Stopover-site Fidelity at a Near-coastal Banding Site in
Scott G. Somershoe1,*, Don G. Cohrs2, and Doris A. Cohrs2
Abstract - We documented one Seiurus noveboracensis (Northern Waterthrush) exhibiting
stopover-site fidelity by returning to a near-coastal stopover site at the Butler
Island Auxiliary Station (BIAS) on the Altamaha Waterfowl Management Area in
southeast Georgia during banding operations from 1995–2000. The Northern Waterthrush
was recaptured in fall 2000 after being banded at BIAS in fall 1997. Although
few individual passerine migrants have exhibited stopover-site fidelity, the majority
were recaptured at banding stations nearer (<500 km) breeding populations of the
respective species. Stopover-site fidelity is rarely documented in the southeast, as migration
banding stations are generally located at coastal migrant traps, which primarily
capture hatching-year birds that likely migrate to inland locations in subsequent fall
migrations and do not return to coastal migrant traps. High percentages of hatchingyear
migrants at our near-coastal site suggest that this area is used by migrants in a
similar fashion to coastal sites; however, we found possible benefits received by young
birds returning to this site in subsequent years. Although rarely documented, passerine
migrants may encounter some of the same benefits that wading birds, waterfowl, and
shorebirds encounter in using the same stopover locations annually.
Migrant birds of many different groups have been well documented
exhibiting fidelity to breeding and non-breeding grounds (Greenwood and
Harvey 1982, Holmes and Sherry 1992). Such fidelity provides advantages
of increased familiarity with local resources, territorial dominance, and
predator avoidance (Brown et al. 2002, Latta and Faaborg 2001). The selection
pressures that provide site fidelity to breeding and non-breeding areas
may also be expected to be found in en route migrants (Catry et al. 2004).
Shorebirds, wading birds, and waterfowl have well-documented fidelity
to stopover sites since they tend to be tied to specific habitats that are not
generally available across the landscape, i.e., wetlands, streams, mud fl ats,
lakes, etc. (Evans and Townshend 1988, Harrington et al. 1988, Robertson
and Cooke 1999, Smith and Houghton 1984). We may expect stopover-site
fidelity to be less common in passerines, especially long-distance passerine
migrants, in relation to waterfowl, shorebirds, and wading birds. Indeed,
fidelity to stopover sites along migration routes has rarely been reported in
long-distance migrant passerines in North America (Somershoe and Chandler
2000, Winker et al. 1991) and central Iberia (Bermejo and de la Puente
2002, Cantos and Tellería 1994); however Catry et al. (2004) documented
up to 12.9% of passage migrants returning to the same sites in Portugal.

We find few stopover-site faithful passerines for a couple of reasons.
First, suitable stopover sites are generally in greater supply than for wetland-
specific species. Passerines are more fl exible in their habitat selection
during stopover and can gain weight, or at minimum, maintain weight even
in dry forests (Schaub and Jenni 2001). Second, the typical fl ight speed of
migrating passerines is lower than for larger-bodied geese and shorebirds;
therefore, passerines are more sensitive to wind conditions. A slower fl ying
speed would result in passerines experiencing greater wind drift, likely
needing many more stopover locations, and migration may be much more
dependent on current weather conditions that infl uence whether a bird stops
at a previous stopover location or continues with favorable wind conditions
(Catry et al. 2004).
In North America, stopover-site fidelity has been rarely documented.
Nisbet (1969) published the first compilation of records of stopover-sitefaithful
transients, which he describes as individuals that return to the site of
banding in subsequent years and whose regular breeding and non-breeding
areas are at least 161 km from the banding site. Winker et al. (1991) summarized
8 published articles and found a total of approximately 21 individuals
of 10 species that exhibited stopover-site fidelity. All of these documented
cases were at inland sites (≥40 km from the nearest large water barrier) and
were generally located closer to the nearest breeding populations for the
species. Somershoe and Chandler (2000) documented the first site-faithful
migrants (four Seiurus noveboracensis Gmelin [Northern Waterthrush] and
one Dendroica petechia L. [Yellow Warbler]) at a near-coastal stopover site
(≤40 km from the nearest large water barrier) in southeast Georgia.
The first objective of this paper is to report an additional stopover-sitefaithful
migrant at a near-coastal site in Georgia. Second, we assess possible
benefits to migrants utilizing the same stopover site annually. Third, we
review the literature of stopover-site-faithful passerine migrants in North
America and assess species-specific likelihoods of stopover-site fidelity of
transients. Finally, we address factors infl uencing the likelihood of migrants
to return to stopover sites with respect to distance between the banding station
to the nearest breeding population of the respective species, distance
between the banding station and the nearest large water barrier, and proportion
of hatching-year individuals captured at each site.
We banded birds at the Butler Island Auxiliary Station (BIAS) within
the Altamaha Waterfowl Management Area, a near-coastal site located
approximately 20 km from the Atlantic coastline in southeastern Georgia
(McIntosh County; 31°21'N, 81°26'W). Mist nets were located along a series
of levees used to control water levels on the management area. The levees
and the pond edges adjacent to the net lanes were dominated by Celtis laevigata
Willd. (Sugarberry), Prunus serotina Ehrh. (Black Cherry), Diospyros
virginiana L. (Persimmon), Morella cerifera (L.) Small (Wax Myrtle), and
2009 S. Somershoe, D.G. Cohrs, and D.A. Cohrs 539
Rubus spp. (Blackberry). Altamaha Waterfowl Management Area has a variety
of habitats along the fl oodplain of the Altamaha River, including old
diked rice fields, Pinus spp. savannas, tidal creeks, hardwood fl oodplain
forests, and old-growth stands of Taxodium distichum L. (Bald Cypress).
Although BIAS is not located on the immediate coast nor truly inland, we
consider BIAS a near-coastal banding station because of its close proximity
(≤40 km) to the Atlantic coast. There are extensive fl oodplain marshes to the
east between BIAS, the mouth of the Altamaha River, and Sapelo Island.
We also report data from the Jekyll Island Banding Station (JIBS), a
nearby coastal banding site, on Jekyll Island, Glynn County, GA (31°00'N,
81°25'W). JIBS is 40 km south of the BIAS site on the immediate Atlantic
coast, and nets were placed within early successional habitat at the southern
tip of Jekyll Island. The site is dominated by Quercus virginiana P. Mill
(Live Oak), Wax Myrtle, Serenoa repens Bartr. (Saw Palmetto), and Persea
borbonia L. (Red Bay) (Cohrs and Cohrs 1994).
We operated 12–15 mist nets (12 x 2.6 m, 32-mm mesh) at BIAS daily,
weather permitting, from 29 August through 5 November 1995–2000. We
opened nets at dawn and operated them 6 hours/day (mean of 57 days and
2166 net hrs/year). We operated 9–15 nets at JIBS between 21 September
and 25 October 1986–2001 in a similar fashion to our procedures at BIAS,
with an average of 22 days and 1374 net hrs/year. Each bird captured was
banded with a USGS aluminum band and released at a central banding station
under permit to D.G. Cohrs and D.A. Cohrs.
For comparison of age ratios at other banding stations in the southeast
United States, we assessed banding from two inland banding stations at Wekiva
Springs State Park and Rock Springs Run State Reserve (WSSP/RSRSR)
near Orlando, Orange County, FL (C.R.D. Brown and R.T. Poole, Orlando,
FL, unpubl. data; see Poole et al.  and Somershoe et al.  for site
descriptions). Birds were banded in fall migration, i.e., 1 September through
31 October 1997–2001. We combined data because sites were within 5 km and
consisted of similar habitats. We assessed age ratios at a coastal site of birds
banded at Ft Morgan, AL from 1 September through 30 October 1991–2007,
excluding 1998 and 2003 (F.R. Moore, University of Southern Mississippi,
Hattiesburg, MS, unpubl. data). We generated chi-square values for contingency
table analysis with 95% confidence limits to test the hypothesis that age
ratios were not different between sites (Zar 1996).
One Northern Waterthrush was recaptured on 22 September 2000 after
initially being banded as a hatching-year bird at BIAS on 28 September 1997.
We did not recapture the individual more than once during either year of
encounter. The individual weighed 18.0 g upon original banding and 18.8 g
upon recapture in 2000 and had no fat reserves during either capture.
With 4 site-faithful Northern Waterthrush from Somershoe and Chandler
(2000) and 1 in this paper, 5 of 733 Northern Waterthrush banded at BIAS
540 Southeastern Naturalist Vol. 8, No. 3
from 1995–1999, with returns possible in 1996–2000, exhibited stopoversite
fidelity at BIAS (0.7%). We are unable to assess stopover-site fidelity
in other species as we did not capture many individuals of most transients
species at BIAS during that time span, i.e., only 30 Catharus fuscescens
Stephens (Veery), 20 Dendroica caerulescens Gmelin (Black-throated Blue
Warbler), and 83 Setophaga ruticilla L. (American Redstart); however, 1
of 166 (0.6%) Yellow Warbler returned to our study site (Somershoe and
Of the 5 Northern Waterthrush exhibiting stopover-site fidelity at BIAS,
4 of 5 were hatching-year at the time of initial capture. All individuals
subsequently returned to BIAS on an ordinal date earlier than that of initial
capture, while all but 1 recapture occurred within 10 days of the initial banding
date (Table 1). All individuals had the same or greater fat score (range
0–3) upon recapture. Only 1 individual had a lower mass upon recapture
(0.4 g lower), while the remaining 4 birds averaged 1.5 g higher mass than
at initial capture (range = 0.3–3.2 g). On the other hand, the Yellow Warbler
that returned to BIAS was recaptured on an ordinal date 11 days after initial
banding and with a reduced fat score and mass (1.5 g lower).
We found no stopover-site-faithful individuals of species fitting Nisbet’s
(1969) criteria from >4500 individuals of 13 species banded at JIBS from
1986–2000, allowing for recaptures in 2001. We also did not document any
stopover-site-faithful individuals from >30,500 individuals of 7 species
that do not strictly fit the criteria, but are common during fall migration and
may return annually, i.e., Dumetella carolinensis L. (Gray Catbird), Seiurus
aurocapillis L. (Ovenbird), Dendroica p. palmarum Gmelin (Western Palm
Warbler), Dendroica discolor Vieillot (Prairie Warbler), Geothlypis trichas
L. (Common Yellowthroat), Vireo olivaceous L. (Red-eyed Vireo), and Passerina
cyanea L. (Indigo Bunting).
We did not find stopover-site-faithful birds in either spring or fall at
other coastal stopover sites in the southeast United States where large numbers
of migrants, including those meeting and not meeting Nisbet’s (1969)
criteria are banded annually, i.e., Peveto Woods, LA (>10,000 individuals,
27 species, spring 1982–1991), Johnson Bayou, LA (>19,000 individuals, 25
species, spring 1993–2006), and Ft. Morgan, AL (>31,100 individuals, 31
species, fall 1991–2007) (F.R. Moore, University of Southern Mississippi,
Hattiesburg, MS, unpubl. data). In addition, no stopover-site faithful birds
were found from over 1500 individuals of 13 transient species fitting Nisbet’s
criteria that were banded from 1997–2000 at the inland site WSSP/
RSRSR. We only included species that strictly fit Nisbet’s criteria, as individuals
of several migratory species returned to winter grounds annually,
e.g., Gray Catbird and Ovenbird (Somershoe et al. 2009).
We reviewed and critiqued records of stopover-site-faithful migrants
from the literature and consider 25 individuals of 9 species strictly fitting
Nisbet’s criteria with the inclusion of the 1 new record in this paper
(Table 1). We excluded 3 Dendroica c. coronata L. (Myrtle Warbler) and 2

Zonotrichia albicollis Gmelin (White-throated Sparrow) possibly accepted
by Winker et al. (1991) due to the fact that the banding station was within the
winter range of the species (Foy 1975, Johnson and Lee 1974). Twenty-one
of the 25 site-faithful migrants (84%) returned to a stopover site within 10
ordinal days of the initial banding date, accounting for leap years. Sixteen of
the 25 migrants (64%) were recaptured at banding stations ≤500 km from the
nearest respective breeding population, with 7 of these birds (28%) returning
to sites ≤250 km of the nearest breeding population (Table 1). Only 7
individuals returned to sites ≥700 km from the nearest breeding population.
All documented stopover-site-faithful individuals occurred in fall, with the
exception of 1 Northern Waterthrush in spring (Table 1). The 6 individuals
that returned to BIAS (Somershoe and Chandler 2000 and this paper) are the
only recorded stopover-site-faithful migrants to return to a site ≤40 km from
the nearest large water barrier.

Age ratios of migrants at coastal, near-coastal, and inland stopover sites
were significantly different (Table 2). We found that age ratios at the 2
coastal sites differed for all species. We found that the coastal stopover sites
captured a higher percentage of hatching-year birds than the inland and nearcoastal
site, with the exception of Yellow Warbler at Ft. Morgan and BIAS.
Although nearly all sites had significantly different age ratios, BIAS typically
had hatching-year percentages more similar to those from the coastal
sites than the inland site in Florida, with the exception of Black-throated
Blue Warbler, which had a relatively small sample size at BIAS (Table 2).
The tendency of songbirds to be faithful to stopover sites along the migration
route is rare due to a myriad of potential physical and environmental
factors. Although this phenomenon is uncommon, we found that 48% of
documented site-faithful individuals were either Northern Waterthrush or
Dendroica striata Forster (Blackpoll Warbler), suggesting that they may
tend to exhibit stopover-site fidelity more often than other species. Benefits
of stopover-site fidelity to Northern Waterthrush at BIAS may be evident
from the general pattern of higher mass and fat scores upon recapture as
adults. Northern Waterthrush are territorial on migration, and there may be
benefits of returning to a known stopover site for locating and defending
areas of adequate food resources for fat deposition or replenishment (Rappole
and Warner 1976). The benefit of stopover-site fidelity to Blackpoll
Warbler in eastern Massachusetts may be familiarity of sites for fat deposition,
as these areas are concentration areas near departure locations for the
long offshore migration undertaken by this species; however, we do not have
fat and mass scores for a preliminary assessment (Hunt and Eliason 1999).
Birds with more fat reserves during migration may have a greater chance
of selecting stopover habitat. In addition, the possible benefit of more rapid
deposition of fat and mass at a revisited stopover site and a similar passage
window for the majority of stopover-site-faithful migrants may indicate that
individuals generally have a relatively small migration window and so efficient use of a familiar stopover site can be important. There may be some
physiological benefit of stopover-site fidelity in passerines, but measuring
success of returning individuals is difficult, if not impossible.
The possible benefits of utilizing a stopover site annually may be important
to passerine migrants; however, several factors greatly reduce
the likelihood of a passerine returning to a stopover site. One factor is the
geographic location and distance of the breeding range to the southern most
stopover site. A latitudinal analysis of probability of stopover-site fidelity
is difficult to do with each species having a different breeding range and
location of breeding populations in the eastern United States and Canada.
There appears to be a tendency for stopover-site-faithful migrants to return
more often to sites ≤500 km of the nearest breeding population for the
respective species. Only 7 individuals returned to sites ≥700 km distant.

As migrants reach areas more distant from the breeding grounds, the cumulative
effects of variable wind conditions are more likely to increase
the amount of drift from a possibly predetermined migratory pathway and/
or affect the distance an individual can successfully migrate in a given period
of time. The benefit of correcting for such drift errors, albeit slight or
significant, may not outweigh the cost of expending energy returning to a
familiar patch of forest, whereas the larger benefit of continuing migration
when conditions are favorable likely outweigh the smaller benefit of shortstopping
a flight for a known location. The distance migrants travel from
breeding grounds in Canada and northern United States to southeastern
banding stations is generally >500–700 km and may be too far to adjust for
drift and utilize familiar locations, thus resulting in a scarcity of stopoversite-
faithful records for species that strictly fit Nisbet’s (1969) criteria.
The distance of banding stations to the immediate coast (i.e., nearest large
water barrier) and the segment of the migratory population of each species
using those sites likely affect the probability of stopover-site fidelity. Assessment
of age ratios of passage migrants captured at various locations across
the southeast support the hypothesis that adult birds appear to use more
inland sites during migration, that coastal areas are dominated by inexperienced,
and possibly disoriented, hatching-year birds, and that inland sites
support more adult birds in fall migration (Moore 1984, Murray 1966, Ralph
1978). Ralph (1981) and Moore (1984) also suggested that adult birds have
more experience in migration orientation; thus, we would not expect adult
birds to show fidelity to a coastal site since these individuals are not returning
to coastal areas in subsequent years. Adult birds may also migrate inland
in order to attempt to avoid higher densities of birds along the coastal sites,
possibly reduced availability of resources and/or territories on the coast, and
reduced risk of fl ight error due to wind drift upon initiating a fl ight from the
edge of a water barrier, especially the southeastern Atlantic coast. Many adult
birds captured in fall at migrant traps on the coast of the Gulf of Mexico may
be captured after returning to land as a correction for over-shooting the coast
during a night fl ight and encountering poor migratory conditions (R. Sargent,
Hummer Bird Study Group, Clay, AL, pers. comm.).
The high percentage of hatching-year birds at BIAS suggest migrants
may perceive the site as a coastal location rather than an inland site, although
the proximity of the site prevents clear determination of category.
Regardless, the 6 returning birds at BIAS represent the first records of sitefaithful
transients returning to a site ≤40 km from a large water barrier. The
site-faithful birds banded as hatching-year at BIAS in a site dominated by
inexperienced, hatching-year birds, returned to utilize the near-coastal location
and may have been able to take advantage of familiarity of the site and
knowledge of resources in order to increase body fat and mass. The higher
percentages of adult birds at inland sites and the lack of site-faithful migrants
at banding stations on the immediate southeastern Atlantic coast suggests
possible inter-annual variability in migration routes between age classes.
We also suggest that stopover-site fidelity may be a small and generally
2009 S. Somershoe, D.G. Cohrs, and D.A. Cohrs 545
unimportant factor to long-distance migrant passerines in North America.
Further research comparing stopover length, rates of fat and mass deposition,
and age ratios may elucidate differences in migratory behavior of birds
between coastal, near-coastal, and inland sites.
