Thorington1,2,* and Kimberly B. Brand3 Abstract - Habitat islands, corridors, and patches within the urban–rural mosaic provide important resources for migratory and resident species and may be crucial for breeding success and survival. In suburban areas, corridor width and patch size are strongly correlated with community composition. We assessed the breeding bird community in the Historic Bethabara Park Complex (HBPC) by territory mapping during April–July 2009 and 2010. HBPC is a 77-ha habitat island in Winston-Salem (Forsyth County), NC. We detected 109 bird species in HBPC, including 60 for which we documented at least 1 breeding territory in either year. Each year we found territories of 58 species; 57 species were the same between years. The majority of birds encountered in this study nest in the canopy, in shrubs, or in cavities. The breeding community was roughly split between migrants (32) and residents (34) and included 3 exotic species. We documented territories for 10 woodland interior specialists including Hylocichla mustelina (Wood Thrush), Seiurus aurocapilla (Ovenbird), and Piranga olivacea (Scarlet Tanager). Two of these observed bird species—Wood Thrush and Sitta pusilla (Brown-headed Nuthatch)—are designated as US birds of conservation concern by Partners in Flight (PIF). Eight of the species we documented are considered by PIF to be species of conservation concern in the Piedmont Region during the breeding season and and 3 of these are common species in steep decline: Chaetura pelagica (Chimney Swift), Megaceryle alcyon (Belted Kingfisher), and Colaptes auratus (Northern Flicker). HBPC is historically and currently species-rich and has a community composition similar to that seen in other NC Piedmont studies. We recommend periodic monitoring as the local landscape and climate change. Further research is needed to determine to what degree the park complex functions as an oasis or population sink for the bird community, especially for forest-interior obligates, Neotropical migrants, and species of concern. Introduction Like much of the eastern US, North Carolina has experienced rapid increases in population and urbanized land use (Brown et al. 2005, City–County Planning Board 2012). Urbanization causes disturbances to native biotic communities, including changes in landscape connectivity, increases in invasive plant-cover density, invasive plant-species richness, and homogenization of the bird community (Blair and Johnson 2008, Mason et al. 2007, McKinney 2006, Olden et al. 2006, Rudnick et al. 2012). Habitat loss is one of the major causes of species decline, especially for forest-interior birds and Neotropical migrants (Sauer and Link 2011). Bird-species richness initially increases in response to a minimal level of human disturbance, then 1Department of Biology, Wake Forest University, PO Box 7325, Winston-Salem, NC 27109. 2Current address - Department of Biology, McDaniel College, 2 College Hill, Westminster, MD 21157. 3Audubon Society of Forsyth County, 2170 Faculty Drive, Winston-Salem, NC 27106.

Brand 2014 Vol. 13, No. 4 decreases with denser urbanization (Beissinger and Osborne 1982, Donnelly and Marzluff 2006, Minor and Urban 2010, Tratalos et al. 2007). Higher housing density results in changes in the dominant foraging and habitat guilds, leading to an increase in invasive and granivorous species richness (Mason et al. 2007, Minor and Urban 2010). Suburban woodlots, especially those with connectivity to other greenspace, may become species rich and therefore be important for maintaining biodiversity (Lumpkin et al. 2012, Rudnick et al. 2012, Tratalos et al. 2007). There is an ongoing need for urban habitat-island baseline data (Donnelly and Marzluff 2006, Lumpkin et al. 2012, Marzluff 2001, Minor and Urban 2010). As urban greenspace islands become the predominant available habitat, it is important to know how the composition of the breeding bird community changes over time (Donnelly and Marzluff 2006). Historic Bethabara Park (HBP) in Winston-Salem, NC, is a site on the North Carolina Birding Trail (North Carolina Birding Trail 2008) and is used extensively for hiking, running, seasonal festivals, and birding. The modern bird community is well documented in a county checklist (ASFC 2007), a birding guide (Disher 2010), and on eBird (eBird 2013, Sullivan et al. 2009). Using the Audubon watch list (Butcher et al. 2007, National Audubon Society 2007), and Partners in Flight (PIF 2013a, Panjabi et al. 2012), we gathered information on the conservation status of bird species detected. Historical data and notes from naturalists are often used to inform research on community composition and climate change (Bryce et al. 2002; Ellwood et al. 2010, 2013). The land around and within the park has been noted for its biological diversity since Moravian settlement in the 1750s (Fries 1922, 1925), and modern studies have focused on historical botanical data (Browne and LaVoie 2004, Bynum 1996). In 1762, the botanist J. Bartram described the richness of plant species on the hillside below God’s Acre (the Moravian graveyard in Bethabara) as “a great treasure-house” (Bynum 1996, Fries 1922). Specific written records of The Wachovia Tract (40,058 ha [98,985 ac] in present-day Forsyth County, including Bethabara and Winston- Salem) start with the surveyor C.G. Reuter’s notes and the Moravian diaries, which document several bird species that are now very rare (Caprimulgus vociferous [Whip-poor-will] and Colinus virginianus [Northern Bobwhite]), extirpated from Forsyth County (Bonasa umbellus [Ruffed Grouse]), or extinct (Ectopistes migratorius [Passenger Pigeon]) (Davis 2000, Fries 1925). Although these records, especially Reuter’s bird surveys, were not systematic because he focused on fauna and flora that were economically valuable or dangerous to humans, these writings suggest a diverse and potentially rich avifauna (Fries 1925). The detailed land-use knowledge and the availability of historical and countylevel records make the Historic Bethabara Park Complex an ideal location to address the effects of anthropogenic change on the breeding bird community. Territory-mapping methods are a good way to collect a detailed snapshot of the bird community at a particular site (Bibby et al. 2000). Data generated from mapping provide information on whether a specific location should be targeted for continued monitoring to elucidate patterns associated with habitat and climate change over the coming decades (La Sorte and Boecklen 2005). To that end, our goals were Southeastern Naturalist K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 772 to 1) conduct a study to provide 21st-century baseline breeding-bird data from HBPC that will facilitate documentation of future changes associated with local human land-use, invasive species, climate change, and habitat-island source-sink dynamics; and 2) present a replicable model for the use of territory mapping in citizen-science monitoring by Audubon chapters or bird clubs. We expected the bird community at the HBPC to be similar to those documented by other Piedmont area studies (Mason et al. 2007, Minor and Urban 2010). Field-site Description The Historic Bethabara Park Complex (HBPC; 30°09'N, 80°18'W) is comprised of Historic Bethabara Park, Bethabara City Park, and several privately owned parcels where public access is allowed. HBPC’s 74 ha include a large wetland (5.3 ha), vernal pools (2.5 ha), 2 creeks (2.6 ha), woodlands (30 ha hardwood, 16.2 ha Pinus [pine], 4 ha mixed), and grassy/human-modified areas (13 ha) (Fig. 1). We used ArcGIS 10.1 (ESRI, Redlands, CA) to measure habitat areas. Due to the nature of park and property edges, our census covered 77 ha. The additional 3 ha are suburban edges of the park complex. The 2 main creeks that run though the riparian woodlands were straightened and deepened by dredging in the 1930s and 1940s, and are heavily eroded urban/suburban streams (Bridle 1996). Upland areas are variably aged second-growth forest, resulting in patches of river bluff forest, Quercus (oak)–Carya (hickory) forest, successional Pinus (pine) stands, and mixed successional patches. Along the creeks, alluvial forest and basic mesic forest are the primary plant communities (for detailed community descriptions see Spira 2011). Figure 1. Habitat composition of the Historic Bethabara Park Complex in which the census was conducted. Southeastern Naturalist 773 K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 The understory along the creeks is heavily influenced by invasive species such as Ligustrum spp. (privet), but native shrubs—Corylus americana Walter (American Hazelnut), Lindera benzoin (L.) Blume (Northern Spicebush), Asimina triloba (L.) Dunal (Common Pawpaw), and Alnus serrulata (Aiton) Willd. (Tag Alder) —persist. HBPC retains a variety of native ephemeral wildflowers and other native herbs (K.K. Thorington and K.B. Brand, pers. observ.). Since European settlement, the Bethabara wetland has consisted of wetlands, bottomland wet forest, and farmland. The current pond and marsh area formed in the early 1990s as a result of construction activities by humans and Castor canadensis Kuhl (Beaver) (Bridle 1996). Today it consists of 2–3 ha of seasonally fluctuating open water surrounded by a 2–3-ha Scirpus sp. (bulrush) and Typha latifolia L. (Common Cattail) marsh with encroaching woody vegetation. A few snags remain from the bottomland forest that grew after farm abandonment (due to increased wetness) after 1941 (Tennant 2007). Much of the open water is covered annually by exotic Nelumbo nucifera Gaertn. (Sacred Lotus). The landscape around the Park is primarily suburban residential. Building density and usage measures were generated in ArcGIS 10.1 using publicly available data from the City of Winston-Salem (http://www.cityofws.org/Home/GIS/Articles/GIS). Using imagery from Google Earth (Google, Inc., Mountain View, CA), the 2005 structure data layer from the City of Winston-Salem was updated to include new structures built within 1 km of the park from 2005 to 2010. Building density (mean ± st dev) is 3 ± 0.05 structures per 1 ha within a 1-km radius of the park (total area = 8.4 km2; 65% single-family homes [SFH], 16% apartment complexes [AC], and 12% business and industry [BI]). Within a 5-km radius of the park, average structure-density is 2.6 ± 0.43 structure/ha (total area = 102.3 km2; SFH 69%, 6% AC, and 15% BI). Methods Field methods Twelve birders from the Audubon Society of Forsyth County conducted territory mapping following methods from Bibby et al. (2000). Each had a minimum of 10 years experience identifying birds (average for all 12 was 25 years, the most experienced had 45 years), and the two with the least experience have advanced biology degrees and formal ornithological research training. In April 2009, these individuals spent an average of 15 days a month birding when not involved in this work. We accompanied these observers on their first territory-mapping visit to provide on-the-ground training and methods clarification. The 77-ha complex was divided into 5 census areas ranging from 12 to 21 ha each (Fig. 2). Observers canvassed census areas on foot, passing within 50 m of every point inside the park complex and as close as practical to the perimeter. Use of the 14.5-km trail system brought observers within 25 m of 53 ha—69% of the total census area—and within 50 m of 71 ha—92% of the census area (Fig. 2). In the few spots of HBPC where trails did not pass within at least 50 m of each other or the census-area boundary, observers walked off-trail except in those parts of the wetland that would have required walking in water. Each census visit started at a different location to avoid time biases. A Southeastern Naturalist K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 774 pair of observers shared responsibility for visiting each area 10 times between 12 April and 4 July, with each observer visiting the area 4–6 times. Observers were the same between years, except 3 in 2009 and 2 in 2010 who performed surveys in one year only. Both K.K. Thorington and K.B. Brand performed surveys for >1 census area in both years. Census-area visits occurred approximately 7 days apart. The visit week averaged 7.2 d (range = 3–17) in 2009 and 7 d (range = 3–11) in 2010. Observation sessions lasted an average of 2 h and 35 min ± 44 min. Observers conducted sessions primarily between sunrise and 11:00 h, and each session began within 1.5 h after sunrise. Three evening surveys, 1 in 2009 and 2 in 2010, occurred between 17:00 h and sunset. No census visits were performed during rain, heavy fog, or wind greater than Beaufort scale 5 (small trees in motion). Observers recorded all birds detected—using standard codes for species, sex, age, behavior, and movement— on a 1:2400 field map generated in ArcGIS 9.3 (ESRI). We transferred observation data from field maps to cumulative species maps for each season and archived species-count data on eBird (eBird 2013). The eBird observer is listed as HBP/ASFC BBC20092010 for all lists. Project lists are personal locations. The first author conducted additional surveys for low-detectability and nocturnal or crepuscular species such as owls. We examined data from additional surveys after compiling species-specific maps for each season. In 2010 and 2011, late winter (25 January–15 March) evening surveys were conducted to detect Scolopax Figure 2. Breeding bird census areas in HBPC showing the park trail system, roads, and creeks. Census work was conducted primarily from the trails because 92% of habitat within the park is ≤50 m from a trail. In locations lacking trail access within 50 m of a point, offtrail surveying was conducted as part of a census visit. Census areas were measured to the nearest hectare. Southeastern Naturalist 775 K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 minor (American Woodcock). In 2009, 6 observers used location data from census observation-sessions to guide nest-searching activities for a pilot study of Wood Thrush nesting success. Territory analysis We assessed observations of each species for the entire study season in each year to determine the number of territories (Bibby et al. 2000). If a species was detected during ≤8 census visits, the minimum requirement for a territory was 2 detections at least 10 days apart. If a species was detected during ≥9 of the 10 visits, the minimum requirement for a territory was at least 3 detections. A single observation of a nest with eggs or young automatically defined a territory (Bibbey et al. 2000). We consulted the Birds of North America Online species accounts (Poole 2005) for known territory sizes to set the maximum distance between observations defining a territory cluster. For highly detectable common species such as Cardinalis cardinalis (Northern Cardinal), we looked for a continuous temporal spread of observations across the season and viewed territories with only 3 detections skeptically. For colonial, semicolonial, and non-territorial species, we determined the number of breeding pairs/ groups via a group-cluster count analysis where the second highest count-number of breeding males, in sexually dimorphic species, or the second highest number of adults divided by 2 within an observed cluster, defined the number of territories (Bibby et al. 2000). We required the presence of a potential suitable nesting site within a reasonable distance of the observed cluster, i.e., chimneys for Chimney Swifts, in order to recognize a territory. We treated edge territories in the same manner as internal territories (not as half, as in Bibby et al. 2000) because our goal was to determine species usage of the entire HBPC. Generally, we did not treat observations of fledglings and fly-overs as territory-defining registrations. Analyses and statistics We classified birds according to behavioral guilds (foraging, nesting, migration, and habitat preference; Ehrlich et al. 1988, Mason et al. 2007, Minor and Urban 2010, Poole 2005). To test whether the number of species detected in each habitat guild was similar to the availability of habitat we used a chi-squared statistic. PIF continental combined scores (CCS) and regional concern scores-breeding (RCS-b) were collected from the PIF online species-assessment database (PIF 2013a, Panjabi et al. 2012) for the observed bird community to quantify the number of concern and watch-list species (higher scores) and to provide comparisons with other regional studies. Regional scores are for the Piedmont, bird conservation region 29 (BCR29; PIF 2013b). We calculated territory densities for species considered of concern at either the regional or national level or both. Interpretation of historical records In addition to the published bird-population records from the 20th and 21st century (ASFC 2007, Disher 2010), K.K. Thorington examined both the original documents and English translations of 1764 Wachau or Dobbs Parish, attributed to Christian Gottlieb Reuter (Fries 1925), and Reuter’s Booklet for the Land Register about Southeastern Naturalist K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 776 Wachovia, 1760 (Huber 1953); the Fries (1925, 1922) translations of the Moravian diaries were also examined. The Wachovia Tract (Wachau or Dobbs Parish) was 40,058 ha (98,985 ac) that encompassed what is now the City of Winston-Salem, including HBPC. To create a minimum estimate of 18th-century species richness, we compared bird names and notes from these documents to modern bird descriptions in European and American field guides (Jonsson 1992, Mountfort et al. 1993, National Geographic 2002, Peterson 2002, Sibley 2000). This minimum estimate is a count of distinct species with categories such as ducks counted as a single species, and thus undercounts the species richness observed during the 18th century. We determined an expanded estimated range by counting present-day species in those categories, using the bird assemblage now present in Forsyth County to provide a proxy for species richness (numbers, not identity) in the 18th century, with the exclusion of known introductions (e.g., Sturnus vulgaris [European Starling]; Cabe 1993) or range expansions (e.g., Molothrush ater [Brown-headed Cowbird]; Lowther 1993). The low end of this expanded estimated range includes species in Reuter’s categories that are now common. The high end of the range includes irruptive species and those seen routinely but not annually, such as Sitta canadensis (Red-breasted Nuthatch). Results We detected 109 species of birds in the Historic Bethabara Park Complex: 101 in 2009 and 95 in 2010 (Appendix 1). In 2009, observers recorded 6464 bird observations resulting in an average 646 ± 94 detected birds per visit week, or 8 ± 1 birds per ha in HBPC. In 2010, observers recorded 6665 birds, average 667 ± 123 birds per visit week or 9 ± 2 birds per ha. Of the 109 species detected, 87 were documented Forsyth County breeders and represent 81% of the 107 known and historical Forsyth County breeders (ASFC 2007, Disher 2010). The other 22 species detected were a combination of winter residents and passing Neotropical migrants. Fifty-nine of the known breeding species (ASFC 2007, Disher 2010) had at least 1 breeding territory in either year, with Archilochus colubris (Ruby-throated Hummingbird; 2010 only) and Icterus spurious (Orchard Oriole; 2009 only) the only species not to have at least 1 territory documented in each year (Appendix 1). Observations for Setophaga caerulescens (Black-throated Blue Warbler) met territory criteria for 2 territories in 2009; however, with no breeding records in the county, and taking into account the proximity to known mountain breeding grounds (Holmes et al. 2005) and the seasonal timing (birds were only present on area visits 26 April–21 May 2009), we do not consider it a breeder. We found 544 territories of 58 species in 2009 and 618 territories of 58 species in 2010. Eighteen species had fewer territories (total of 40 less) in 2010 than in 2009, 24 species had more territories (total of 114 more), and 18 species had the same number of territories between years. Half of the additional territories came from 4 highly detectable common species: Northern Cardinal (20 more territories), Turdus migratorius (American Robin; 17); Poecile carolinensis (Carolina Chickadee; 11 more territories); and Thryothorus ludovicianus (Carolina Wren; 9 more Southeastern Naturalist 777 K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 territories). Territory-number reductions were more evenly spread between the 18 species: 8 species had 1 less territory and 8 had 2–4 fewer territories. Geothlypis trichas (Common Yellowthroat) had the largest reduction in territory numbers (8 less) between years. The nesting-guilds of HBPC breeders were cavity (33% of species), canopy (28%), shrub (30%), ground (12%), and other (0.1%); species nesting in multiple types were counted at each location. During our census, we found a total of 62 nests of 23 species—2009: 34 nests, 16 species; 2010: 28 nests, 16 species. We observed fledglings or family groups of 30 species, 23 species per year. Foraging strategies were dominated by breeding season insectivores (67%; Appendix 1). Breeding birds were roughly split between Neotropical migrants (37%) and resident species (56%) with a few short-distance migrants (17%) and 3 exotic species (Appendix 1). Breeding species composition reflects available habitat in the park and did not differ from the available habitat (χ 2 = 7.1, P ≥ 0.15, df = 5; Table 1). Of the 87 Forsyth County breeders observed, the 78 land birds had an average PIF CCS of 8 (range = 5–14; Appendix 1; for details of scoring criteria see Carter et al. 2000, Nuttle et al. 2003, Panjabi et al. 2012). The average CCS for the 51 HBPC breeding land birds was 8.9 (range = 5–14). PIF scores are not available for the 9 non-land birds observed breeding in HBPC. Of the species we observed, Brown-Headed Nuthatch (CCS 13) and Wood Thrush (CCS 14) had the highest PIF CCS and were the only species listed on the continental PIF watch lists (PIF 2013a). The lists were revised in 2012, and Brown-headed Nuthatch is listed multiple ways (PIF2013a, b). At the regional level, the mean PIF RCS-b was 12.8 (range = 8–17). For the 51 breeding land-bird species that had territories in HBPC, the mean RCS-b was 10.9 (range = 8–17). Ten of these species were of regional concern—Chimney Swift, Belted Kingfisher, Northern Flicker, Dryocopus pileatus (Pileated Woodpecker), Contopus virens (Eastern Wood Pewee), Tyrannus tyrannus (Eastern Kingbird), Hirundo rustica (Barn Swallow), Brown-Headed Nuthatch, Wood Thrush, and Pipilo erythrophthalmus (Eastern Towhee)—and 2 species—Chimney Swift, Table 1.

We documented breeding territories of 10 woodland interior-specialist species in HBPC (Appendix 1). Of these species, we found nests for Accipiter cooperii (Cooper’s Hawk), Buteo lineatus (Red-shouldered Hawk), Strix varia (Barred Owl), Pileated Woodpecker, and Wood Thrush. Observers detected at least one fledgling of all these woodland interior specialists except Pileated Woodpecker. In each year, Barred Owls fledged 2 chicks. Red-shouldered Hawks fledged 3 chicks in 2009, but no Red-shouldered Hawk chicks were observed in 2010. Because overall detection of fledglings was low, lack of fledgling observations says little about whether or not a particular pair or species successfully fledged young. In the 2009 Wood Thrush pilot study, we found 9 nests and 21 territories; 2.8 territories per 10 ha. Nests were located in a variety of plant species: 1 in privet, 3 in Fagus grandifolia Ehrh. (American Beech), 1 in Ulmus americana L. (American Elm), 2 in Acer sp. (maple), 1 in Elaeagnus angustifolia L. (Russian Olive), Table 2.

In 2010 when we were not looking specifically for nests, we found 18 territories and 1 nest; 2.4 territories/10 ha. These territories were concentrated in low-lying riparian areas (HBPC east side sites: territory densities were 2.4 territories/10 ha in upland areas and 10 territories/10 ha in riparian areas in 2009, and 1.4 territories/10 ha upland and 7.7 territories/10 ha riparian in 2010; HBPC west-side sites: territory densities were1.5 territories/10 ha upland and 1.3 territories/10 ha riparian in 2009, and 0 territories/10 ha upland and 3.1 territories/10 ha riparian in 2010; Fig. 3). The Brown-headed Nuthatch is a regional species of highest concern for the Piedmont BCR29 (ACJV 2013). Territories were concentrated in habitats with access to pine stands with a territory density for the whole park of 0.5 per 10 ha in 2009 and 0.8 per 10 ha in 2010 (Fig. 4). In pine habitat only, the density was 2.4 per 10 ha in 2009 and 3 per 10 ha in 2010. The lead author’s examination of the historical records shows that Reuter recorded 36 bird categories in his 1764 Wachau or Dobbs Parish list (Fries 1925). A close reading of the translated records produced a conservative minimum recordedspecies richness in 1760 and 1764 of 38 (Appendix 2; counting the heron and owl Figure 3. Approximate locations for the activity center of Wood Thrush territories observed in 2009 (Squares) and 2010 (Circles). Territory locations show similar habitat-usage patterns in both years. Nest = yes indicates a nest was found. Nest = no indicates that we did not find a nest. Nest = Pilot indicates a nest was found during the pilot study but is not associated with a detected territory. Note that within the higher density of territories on the east side of HBPC, the wooded, wet lowland areas are more densely used than upland areas. In 2009, we found 5 territories with nests (out of the 8 found) located in the vernal pool behind the historic village (arrow); of these, 2 nests were active simultaneously during visit week 5, and 3 other nests were active visit week 8. Southeastern Naturalist K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 780 categories as 2 species), of which 24 are individual species and 14 are species groups. We are confident of the hypothesized identification for 17 species and 14 groups, with only 4 species lacking a hypothesized identification (Appendix 2). The Passenger Pigeon has gone extinct, Ruffed Grouse has been extirpated from the county (ASFC 2007) and North Carolina, and Meleagris gallopavo (Wild Turkey) populations were drastically reduced—possibly extirpated from Forsyth County— and successfully reintroduced (Disher 2010, Eaton 1992). The count of present-day species in Reuter’s categories produced an extrapolated estimate of 63–114 species, including 26–52 breeders (Appendix 2). Discussion The diversity of the bird community within Historic Bethabara Park and the surrounding landscape makes it a particularly rich place. Of the 109 species detected in the park, 87 were known Forsyth County breeders and 60 had breeding territories. Of the 39 Neotropical migrants observed, 22 established breeding territories. Other studies of North Carolina Piedmont habitat islands and greenways generally observed similar breeding bird-community composition, but fewer bird species overall than our study, despite their larger study sampling areas and greater number of study sites. In part, this is likely due to study design and focus; using point counts, Mason et al. (2007) reported 53 breeding species of which 16 were Neotropical migrants. Similarly, Minor and Urban (2010) recorded 19 Neotropical Figure 4. Approximate locations for the activity center of Brown-headed Nuthatch territories. In 2009, 50% of territories were in pine stands; in 2010, 83% were in pine stands. Nest = yes indicates a nest was found. Nest = no indicates that we did not find a nest. Southeastern Naturalist 781 K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 migrants out of 54 breeding species. They observed a total of 69 species compared to our total of 109. In 272 point-count locations, they observed 4 PIF watch list species: Brown-Headed Nuthatch, Wood Thrush, Mniotilta varia (Prothonotary Warbler), and Geothlypis formosa (Kentucky Warbler). PIF CCS scores ranged from 5 to 15 in the triangle region of NC (Minor and Urban 2010), compared to our 5–14 range. Mason et al. (2007) did not use PIF scores to categorize their bird assemblage; however, they observed 3 watch list species: Brown-Headed Nuthatch, Wood Thrush, and Prothonotary Warbler. Both Prothonotary and Kentucky Warblers have been seen in HBPC during migration (eBird 2013), but were not detected during our census. Both Triangle area studies began a month later than our study, in mid-May, so smaller numbers of Neotropical migrants are not surprising. Insectivorous species dominated the counts recorded in all 3 studies. Our study detected the largest number of carnivores because we found hawk and owl nests, which are more likely to be found during multiple-hour census visits than during 8- or 10-minute point-count surveys. Territory mapping differs from point counts, distance sampling, and breeding bird survey methods in that it requires the observer to travel throughout the census area and accurately record observations on a map. Visual confirmation of familiar and unfamiliar songs and calls is encouraged; these methods allow more time for detailed observations of courtship, breeding, and other behaviors. Territory-mapping methods, as used in our study, are less sensitive to space-related variability issues (MacKenzie et al. 2002) than point counts and line transects because the entire area of interest was covered by the census. Gottschalk and Huettmann (2011) suggested that the 50-m distance recommended by Bibby et al. (2000) is too wide a spacing, and recommend reducing the spacing but did not give a specific distance. Windy conditions and anthropogenic background noise reduce song and calldetection probabilities and observer accuracy at distances beyond 40 m (Simons et al. 2007). In our study, although we followed Bibby’s (2000) 50-m rule, in practice we passed within 25 m of 69% and 30 m of 82% (63 ha) of the census area because of the extensive trail network and open space. Working within 25–30 m allowed for increased detection of elusive species. For most species, our territory-mapping methods were also less sensitive to non-detection and over-detection errors than other methods because the measure of abundance is the seasonal territory rather than the count statistics (birds detected on one visit; MacKenzie et al. 2003). This difference is likely to be especially important in urban and suburban habitat islands because the duration and repetition of census visits increases detection for all species despite anthropogenic noise (Gottschalk and Huettmann 2011, Simons et al. 2007). In any study, there will be some gap between birds present (availability) and birds actually detected (detectability; Simons et al. 2007). Species detectability and timing of breeding influence these data. In 2010, Carolina Bird Club members found a Ruby-throated Hummingbird nest that signified a territory not found on our census visits. American Woodcock also may breed in the park; however, their territorial displays occur between late January and mid-March in this part of NC (Keppie and Whiting 1994), a period outside of our sampling Southeastern Naturalist K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 782 dates. Offseason surveys in 2010 and 2011 identified 2 American Woodcock territories in 2010 and 1 territory in 2011, which increases the total number of known park breeders to 60 (Appendix 1). Additional surveys conducted for Ovenbirds, another low-detectability/low-density species, resulted in the same territory number (1) as the 2009 census data, so these additional surveys for that species were not continued in 2010 and were excluded from the territory analyses. Because Forsyth County breeding records exist for Ovenbirds, we counted them as breeders. Coccyzus americanus (Yellow-billed Cuckoo) may also be an off-season breeder for which additional surveys in July would be helpful; however the oddities of their breeding system (Hughes 1999) may make territory mapping a poor choice for this species. Wild Turkey populations are on the rise (Butcher and Niven 2007, Disher 2010), and regular reports on the Forsythbirds listserve and eBird of Wild Turkeys with young suggest that they nest near or in the park. Because home-range size is highly variable (300–24,590 ha), territory mapping within a 77-ha area is unlikely to adequately capture the status of the Wild Turkey (Eaton 1992). The four species that gained large numbers of territories between years are common and highly detectable; thus, over-detection may have occurred. For example, the apparent Northern Cardinal territory increase may have been caused when observers used the field notation for simultaneous conspecific detections more frequently in the second year of the study, allowing for finer resolution of territories. Northern Cardinal breeding-territory density is close to 1.1 territories/ha compared to the range in the literature of 0.21–2.6 territories/ha (Halkin and Linville 1999). Increases in observer quality have been documented in the North American Breeding Bird Survey (Sauer et al. 1994), but because our total bird observation numbers are similar between years and our observers were experienced before the study, observer experience was likely a minor issue. Housing density has been shown to affect breeding bird densities positively and negatively and to increase predation pressure on birds (Lumpkin et al. 2012, Thorington and Bowman 2003, Tratalos et al. 2007). Bird communities show similar responses to urbanization, classified by road density, noise pollution, and discontinuity of vegetation, as they do to housing density, with changes in species composition, distribution, and behavior (Barber et al. 2010, Minor and Urban 2010). Landscape structure, in terms of road density and proportion of edge habitat of the entire landscape, may be more important than proximity to an edge for a particular edge-species territory (Minor and Urban 2010), but bird responses to habitat features are scale-dependent (Donnelly and Marzluff 2006, McCaffrey and Mannan 2012, Thorington and Bowman 2003). Responses to disturbance are different in suburban and urban habitat islands than at the county or state scale. The Winston- Salem/Forsyth County area is growing and becoming more urbanized; between 1980 and 2010, the Winston-Salem population increased 75 percent, and population density there dropped from 3.3 to 2.7 people per acre. Low-density residential development continues, and the population is expected to grow by 34 percent between 2010 and 2030 (City-County Planning Board 2012). As this occurs, changes in birdcommunity composition may be an indicator of the health of the remaining habitat. Southeastern Naturalist 783 K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 However, these changes will not provide a measure of habitat quality for any one species (Matthew 2007). HBPC is located within a suburban (3 houses/ha) residential area of Winston-Salem. The relatively small area of non-edge habitat in HBPC (12.3 ha) reduces the likelihood of finding successfully breeding woodland-interior obligate species. Forest-corridor width and patch size are strongly correlated with the species richness of forest-interior birds; a crucial minimum forest width of 300 m has been demonstrated in the Triangle area of NC (Mason et al. 2007). Additionally, species such as Empidonax virescens (Acadian Flycatcher), Ovenbird, and Wood Thrush are generally missing from riparian habitats that are less than 95 m wide (Peak and Thompson 2006). The largest contiguous forest patch in HBPC is 27 ha and contains 6 km of trails (Fig. 2), and the width of undisrupted forested habitat averages considerably less than 300 m; nonetheless, we documented territories for 4 interior-forest breeding species. Future monitoring should assess whether these are successful breeding populations producing offspring or whether they represent population sinks with low or nonexistent reproductive success. Wood Thrushes are Neotropical migrants of both continental and regional conservation concern. Territory density was similar between the two study years, but the population will likely face increasing pressure as building density and hard-surface area around the park increase. The Wood Thrush may be responding to habitat patch-size shape and adjacent patch type within the park. During this study, observed densities were much higher on the east side of the park than on the west side (Fig. 3). In the east side of the park, Wood Thrush territory density in riparian woods (10 territories/10 ha) was similar to the higher extreme of densities previously reported (Evans et al. 2011); however in one 2.8-ha patch, territory density was much higher in both years (9 territories in 2009, equivalent of 32.7 territories/10 ha; 4 territories in 2010, 14.5/10 ha). Five of the 9 nests found in the 2009 pilot study were situated within this patch. Each nest appeared to belong to an individual territory. Two nests were active simultaneously during visit weeks 4–5, and 3 others were active simultaneously during visit-week 8. Stem tallies in 0.2-ha (½-ac) sample plots showed that the overstory is mostly Platanus occidentalis L. (American Sycamore; 51%), Liriodendron tulipifera L. (Tulip Poplar; 36%), and Acer rubrum L. (Red Maple; 13%). The shrub understory here was predominantly exotic invasive plants (privet, 85%; Rosa multiflora Thunb. [Multiflora Rose; 13%]). The sandy substrate is regularly inundated with storm water that causes significant disturbance in the herb layer. One of the older forest patches dominated by beech/maple/oak/ hickory forest is uphill to the west. On the west side of the park, there is a similar riparian privet patch (3 ha; overstory consisting of 40% American Sycamore, 29% Tulip Poplar, 26% Red Maple; 49% understory privet, and 46% Multiflora Rose), in which we recorded no Wood Thrush territories in 2009 and only 1 in 2010. This western patch is adjacent to suburban housing rather than hardwood forest, suggesting that patch context may be important in understanding Wood Thrush use of invasive-dominated understory habitat. The concentration of the Wood Thrush population in the eastern low-lying riparian edge-interior woods is of concern because the area is vulnerable to disturbance from activities on the Southeastern Naturalist K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 784 greenway, and erosion from storm-water runoff. We recommend continued assessment of this high-concern species within HBPC and Forsyth County. Monitoring of Wood Thrush breeding demography is labor intensive and proved overly ambitious in conjunction with territory mapping. Brown-headed Nuthatch is an open pine-woods specialist (Cox et al. 2012, Withgott and Smith 1998) and Piedmont BCR29 PIF highest priority species (ACJV 2013, PIF 2013a) With 4 territories in 2009 and 6 in 2010, this small population should be monitored to determine if it is stable. All observed territories were within 125 m of a pine (Pinus sp.) stand and included one or more pines. However, 3 of the 4 known nest locations—those on the wetlands—were in snags standing in permanent water. With common dispersal distances ranging 150–300 m (Cox and Slater 2007), movements of the species to other parks and habitat patches in Winston-Salem may be limited. In addition to the Wood Thrush and Brown-headed Nuthatch, we observed 13 PIF/BCR29 concern species with breeding territories in HBPC. Of those, 8 species— Wood Duck, Belted Kingfisher, Pileated Woodpecker, Eastern Kingbird, Barn Swallow, Carolina Wren, Eastern Towhee, and Indigo Bunting—had territory densities within published ranges in preferred habitat (Brown and Brown 1999, Bull and Jackson 2011, Greenlaw 1996, Haggerty and Morton 1995, Hepp and Bellrose 1995, Kelly et al. 2009, Murphy 1996, Payne 2006). The Chimney Swift and Northern Flicker are common birds in steep decline, and the Northern Flicker had a territory density in HBPC on the low end of the species average (Cink and Collins 2002, PIF 2013b, Wiebe and Moore 2008). Three species—American Woodcock, Eastern Wood Pewee, and Pine Warbler—have lower than expected territory density in HBPC (Keppie and Whiting 1994, McCarty 1996, Rodewald et al. 1999). Wood Duck and American Woodcock are not scored by PIF because they are not land birds, however, the BCR29 local committee considers them high priority (ACJV 2013). Carolina Wren, Pine Warbler, and Indigo Bunting are US/ Canada stewardship species, listed as concern species because they are important indicators of community health (Panjabi et al. 2012, PIF 2013b). Like the present, the second half of the 18th century when the Moravians settled in North Carolina, was a time of landscape change and loss of biodiversity (Davis 2000). Reuter’s documented 36 categories of birds (Fries 1925, 1922) suggest that a diverse bird community was present and provides a context in which to interpret the contemporary bird assemblage. Our expanded species-richness range has limitations in that it is based on non-systematic surveys and uses the present-day bird assemblage as a proxy to extrapolate species richness in the 18th century. That said, it is interesting to note that our extrapolation (63 to 114 species) is similar to our present-day breeding season total (109 species). Both counts represent approximately ½ of current Forsyth County species richness (257; Disher 2010). The similarity between postulated historical and current systematically measured species richness suggests that human modifications to habitat have not greatly reduced local species richness. Alternatively, contemporary Forsyth County and HBPC species richness may be momentarily greater due to the initial increases of species Southeastern Naturalist 785 K.K. Thorington and K.B. Brand 2014 Vol. 13, No. 4 numbers commonly seen with exurban and suburban development (Lumpkin et al. 2012, Mason et al. 2007, Minor and Urban 2010, Rudnick et al. 2012, Tratalos et al. 2007). Continued work on the Moravian documents with translations focused on biological questions could further inform contemporary studies. It is likely that un-translated descriptions of birds, especially game species such as ducks, exist in the early diaries. Any notations of Wood Thrushes would be particularly interesting; based on historical data from Cambridge, MA, Ellwood et al. (2010) noted that Wood Thrush was the only species to arrive later in warmer years. The temperature dependency of Wood Thrush arrival dates is a pattern to follow in future monitoring of Wood Thrush populations. Our goal of creating a replicable citizen-science model for periodic locationspecific monitoring was successful. Our results provide a robust comparison for future repetitions of the census. Audubon Christmas (http://birds.audubon.org/ christmas-bird-count) and spring bird-counts published in The Chat (http://www. carolinabirdclub.org/chat/) have traced the species assemblage though the 20th century. These modern citizen-science efforts provide a coarse-resolution measure of bird occurrence and abundance useful for analysis at the county, state, and continent level (Bibby 2000, Dickinson et al. 2012). Territory mapping, as used in this study, provides a detailed snapshot with fine spatial resolution. For example, we found an average of 19.5 Wood Thrush territories per season, suggesting 36–42 Wood Thrushes in HBPC each spring, whereas eBird high-count data for 2009 and 2010 suggest a maximum of 11 birds. With ongoing rapid urbanization and climate change, more comprehensive systematic surveys and location-specific monitoring are needed. As a direct result of this study, Forsyth Audubon members have powerful information for future conservation efforts at Historic Bethabara Park. In particular, the territory maps for concern species will provide a valuable tool as Forsyth Audubon members advocate for bird-friendly management practices throughout the county.

Reuter’s 36 categories of birds listed in 1764 Wachau or Dobbs Parish–attributed to Christian Gottlieb Reuter (CGR; Fries 1925), and Reuter’s Booklet for the Land Register about Wachovia, 1760 (Huber [1953] unpublished translation for Old Salem, Inc). Category is the English name or phrase used by CGR and his translators. Current name is from the AOU checklist (http://checklist.aou.org/; Chester et al. 2012). Names are of the modern bird that is most likely to be the bird(s) on Reuter’s list. Superscripts: AForsyth County breeders, BHBPC breeders, and Cbirds for which we have high confidence of the contemporary identification that are no longer found in HBPC (they may be rare in the county, extirpated, or extinct). Names of other county resident bird species not recorded from HBPC are excluded for brevity. Count = the contemporary Forsyth County richness for each category regardless of breeding status (ASFC 2007, Disher 2010, eBird 2013). We used this count and an expanded version to extrapolate the potential historical richness range to 63–114 species. Extant birds are followed by extinct species then b y unidentified species. Category Current names Count Notes Wild Geese 1 CGR is possibly referring to multiple species but gives no specificity. Canada Goose, Branta canadensisB Other geese are occasionally present in winter. Ducks 4 No specificity. Currently, Mallard and Wood Duck breed in HBPC. Mallard, Anas platyrhynchosB Bufflehead and Blue-winged Teal pass through HPBC. 14 other Wood Duck, Aix sponsaB species occur with annual frequency in the county (Disher 2010). Bufflehead, Bucephala albeola (L.) Blue-winged Teal, Anas discors Partridge 1 Not resident in HBPC. Breeds in county. ID from Davis (2000).

Thrush 1 Translation states “thrushes … male is blood-red”, is most likely the Eastern Bluebird, Sialia sialis American Robin; however, Wood Thrush or transient spotted thrushes Veery, Catharus fuscescens (Stephens) are possibilities as they look more like European thrushes. The low Gray-cheeked Thrush, Catharus minimus (Lafresnaye) count here is 1 because there is no indication that CGR is talking Swainson’s Thrush, Catharus ustulatus (Nuttall) about more than one species.
