Unusual Food Items from Stomachs of American Badgers
(Taxidea taxus) in Expanding Range in Arkansas
Renn Tumlison1,* and Allison Surf1
Abstract – Taxidea taxus (American Badger), historically a prairie species, has expanded its range
southeastward in Arkansas likely due to habitat alterations resulting from agricultural modification
of the landscape. Its typical foods are an array of small mammals, and seldom have amphibians
been documented in its diet. Northeastern Arkansas was prone to flooding prior to the construction
of levees, and American Badgers have since colonized the agricultural habitat that developed after
flooding stopped. We found that 2 road-killed badgers collected from a newly established population
in northeastern Arkansas had consumed many frogs. This is the first account of numerous amphibians
documented in the diet of badgers.
Taxidea taxus (Schreber) (American Badger, hereafter Badger) is typically considered
to be an inhabitant of plains habitats and is observed less often in forested areas (Bee et al.
1981, Caire et al. 1989, Davis and Schmidly 1994). Badgers are most common where the
soil has a sandy-loam texture, as often occurs in agricultural habitats (Apps et al. 2002, Bee
et al. 1981). In recent years, however, populations have extended their ranges southward
from some northern states (Lindzey 2003) and eastward in the northern US (Nugent and
Choate 1970), Texas (Davis and Schmidly 1994), Oklahoma (Tumlison and Bastarache
2008), and Arkansas (Tumlison et al. 2012). The eastern expansion followed habitat alteration
caused by logging and land clearing (Lindzey 2003, Schwart z and Schwartz 1981).
Heidt et al. (1996) concluded that the Badger was rare in Arkansas. However, deforestation
and construction of levees and drainage systems in the Mississippi alluvial plain
of eastern Arkansas accommodated agriculture and made the area more prairie-like. In
addition, the well-drained loessal soils forming Crowley’s Ridge provided good burrowing
habitat, which likely permitted the recent establishment of a population of Badgers in
northeastern Arkansas (Tumlison et al. 2012).
Generally, the Badger is a grassland carnivore preying most heavily on burrowing
mammals such as rabbits (Leporidae), ground squirrels (Sciuridae), gophers (Geomyidae),
Marmota monax L. (Woodchuck), and small rodents (Lindzey 2003, Mumford and Whitaker
1982). Presence of rabbits, Woodchucks, and many smaller rodents in agricultural areas of
northeastern Arkansas may provide an abundant food supply suitable for Badgers (Tumlison
et al. 2012). However, range expansion also can provide opportunities to incorporate new
food items into the diet of an opportunistic predator.
We examined stomachs of 2 badgers that had been killed on highways in northeastern
Arkansas during 2014. Both specimens appeared to be healthy and had good stores of fat.
We collected an adult male Badger in Mississippi County on AR St. Hwy 18 near Manila,
about 1.6 km west of Big Lake National Wildlife Refuge (GPS 35.872112°N, 90.156273°W)
on 21 August 2014. The stomach contained remains of arthropods including 25 green and
8 brown stink bugs (Hemiptera: Pentatomidae) and 4 kinds of Coleopterans (1 unidentified
Scarabeidae, 2 unidentified different Carabidae, 1 Harmonia axyridis [Pallas] [Multicolored
Asian Lady Beetle; Coccinellidae], and 1 Diabrotica undecimpunctata Mannerheim

[Spotted Cucumber Beetle; Chrysomelidae]). Interestingly, the stomach was filled with
remains of 16 toads (Anaxyrus spp.) either A. americanus (Holbrook) (American Toad) or
A. fowleri (Hinkley) (Fowler’s Toad. Snout–vent lengths of the toads ranged from 25 mm
to 40 mm. Though the viscera of the toads were mostly digested, the intact condition of the
vertebral column and dorsal skin indicated that the items had been consumed a few hours
prior to the Badgers’ deaths (Harlow 1981).
An adult female Badger had been hit about 5.5 km west-northwest of Marion (GPS
35.22627°N, 90.25420°W) in Crittenden County on 11 June 2014. Her stomach contained
remains of arthropods including 1 green Pentatomid and 3 families of Coleopterans (1 small
adult and 2 small larvae [wireworms] of unidentified Elateridae, 1 Multicolored Asian
Lady Beetle [Coccinellidae], and 1 Labidomera clivicollis [Kirby] [Milkweed Leaf Beetle;
Chrysomelidae]). We discriminated unique bones, and determined that the animal had consumed
a minimum of 7 frogs. Sizes of comparable bones approximated the sizes of those
found in frogs from the male Badger.
Although northeastern Arkansas has been transformed from bottomland to agricultural
land, most roads in the area are lined by ditches that usually contain water throughout the
spring and into the summer. We examined a photo taken just prior to retrieval of the specimen
that revealed a roadside ditch full of water at the collection site in Mississippi County.
We suggest that because both Badgers were road-kills, they may have been foraging along
the roads and had opportunistically fed on mating aggregations of frogs in the ditches. We
collected the 2 Badger specimens ~73 km (45 mi) apart; thus they do not represent similar
feeding patterns in a localized area.
As opportunistic predators, Badgers supplement their diets with a variety of prey
(Lampe 1982, Messick 1987, Sovada et al. 1999). Yet, amphibians have been reported only
rarely in studies of Badger foods. Sovada et al. (1999) found 4 Ambystoma tigrinum Green
(Tiger Salamander) in an adult Badger and 1 frog in a juvenile specimen, Errington (1937)
noted the occurrence of 3 frogs (Rana, currently Lithobates) consumed by Badgers in marsh
country, and Long (1964) considered it unusual to find 5 toads (along with 5 mice) in a Badger
stomach. Notably, badgers of the genus Meles (Asian and European badgers) do feed on
anurans (Nowak 1999).
Our discovery revealed that Badgers occurring along roadway ditches in modified habitats
of northeastern Arkansas might rely heavily on anurans during the summer. We found
numerous insects in the 2 stomachs, but, due to their small size, we believe these most likely
represented foods consumed by the toads that later became prey themselves. Occurrence of
insects has previously been interpreted as remains from foods of prey items that secondarily
appeared in Badger stomachs (Errington 1937). Arkansas Badgers most likely also consume
burrowing mammals, as is typical of the species. However, our results suggest that in
agricultural habitat bordered by roads and ditches, American Badgers can feed heavily on
anurans, a previously rarely reported food item.
