1990). Range and Habitat: Gray Treefrogs are found throughout Their background colors range from green to yellowish to brown. Because they are physically indistinguishable (see below), only their shared range has so far been fully determined. early summer. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. Wright (1932) reports Hyla versicolor (almost certainly H. chrysoscelis) from the Okefenokee Swamp calling from 10 June–13 August. The Cope's Gray Treefrogs (Hyla chrysoscelis) is sympatric (occurs in the same areas) with this species in southwestern Indiana. Flickr photos, groups, and tags related to the "chrysoscelis" Flickr tag. when exposed. They are heavier-bodied than Pine Woods or Squirrel Treefrogs, Interesting Facts: Hyla chrysoscelis is morphologically indistinguishable from H. versicolor and two species are also sympatric throughout much of their ranges. The two species can be distinguished by their range, but even more so by differences in their call structure, which are dictated by chromosomal variations. They are found in a Compared to other North American frog species. - edited by J.D.

Careful The bird-voiced treefrog, D. avivoca, is similar to D. chrysoscelis and D. versicolor, but is smaller (25–50 mm in length vs 32–62 mm for the gray treefrog). Diagnostic leg coloration. Identification: Kentucky’s two kinds of Gray Treefrogs are identical in appearance - both range to just over 2 inches long as adults and have large sticky toe pads that allow them to climb on just about any surface. Hyla versicolor has a longer, slower call with a pulse rate that is about half as fast as […] Willson unless otherwise noted. But the most noticeable difference between them is their forms of sound. The skin of the gray tree frog is lumpy and has a warty appearance. Schrode KM, Buerkle NP, Brittan-Powell EF, Bee MA. The gray treefrog is capable of surviving freezing of its internal body fluids to temperatures as low as -8 °C.

Gray Treefrogs generally breed in fishless wetlands. The inner surface of the hind legs is yellow or orange, sometimes with black speckling. The upper body is dark and warty. Habits: Gray Treefrogs spend much of the year high in This species of frog is very rarely seen on the ground except during the breeding season (Conant and Collins 1998). A detailed account of the nomenclatural and taxonomic history may be found in Johnson (1961, 1966). 1990). Adult H. chrysoscelis have been used in multiple acoustic playback experiments and exhibit phonotaxis towards conspecific cues when selecting a breeding habitat (Swanson et al. Geographic Range Both gray treefrog species, Hyla versicolor and Hyla chrysoscelis, inhabit a wide range from southern Ontario and Maine, westward to central Texas, northwest to Manitoba, and northern Florida. Photos by J.D. These treefrogs can be found in a variety of colors, in fact, each individual frog can assume a variety of different colors (comparable to a chameleon).Their background colors range from … versicolor, differ in the pulse-rate of the mating call, as established by previous workers, but there is much more overlap in the ranges of variation of the two species than has been realized. An isolated colony is also noted in New Brunswick. There is usually a white or yellow spot below each eye. Toe pads are large and rounded. It can range in color from a mottled gray to brown, to green, depending on its environment. protected in our region. For species specific range information, see the attached Range data. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use.

Photo by Todd Pierson Copes Gray Treefrog. apart by appearance, especially since both are so highly variable. The gray treefrog, sometimes called the Northern gray treefrog, is closely related to the Cope’s gray treefrog (Hyla chrysoscelis), with overlapping range and identical physical appearance. Compared to other North American frog species. Auditory brainstem responses in Cope’s gray treefrog (Hyla chrysoscelis): Effects of frequency, level, sex and size. A Cope’s gray treefrog, Hyla chrysoscelis, from Clayton County, Iowa. Ouachita Parish, Louisiana. In those areas, D. versicolor may be present only in the Appalachians. Hyla chrysoscelis . Their size ranges from 1-1.5 in (2.2-4.1 cm). It is almost indistinguishable from the gray tree frog, Hyla versicolor, and shares much of its geographic range. also sympatric throughout much of their ranges. The tetraploid Gray Treefrog is related to the diploid Cope’s Gray Treefrog and is thought to have evolved through multiple hybridization events with different diploid ancestors. Johnson (1959, 1961, 1963, 1966) reported genetic incompatibility between the call types, prompting him to designate the faster trilling call type as H. chrysoscelis … Hyla versicolor is on the left and Hyla chrysoscelis is on the right. The morphologically identical species of treefrogs,Hyla chryoscelis andH. Typically they have a dark “star-shaped” pattern on their back with many small warts. Once thought to Hyla chrysoscelis is often found in small trees or shrubs located near or in bodies of water, and are very well camouflaged against the trunks of these trees. be single species, recent genetic work revealed H. chrysoscelis General description: Cope's gray treefrog closely resembles the gray treefrog (H. versicolor) and can only be distinguished in the field by their call. These two species are distinguishable based on variation in their calls. Cope's Grey Tree Frog (Hyla chrysoscelis) is virtually indistinguishable from the northern Grey Tree Frog (Hyla versicolor).Aside from their geographic range (H. versicolor doesn't get this far south) they can only be distinguished genetically and by their call.The call of Cope's Tree Frog has a frequency that is twice that of Hyla versicolor. Temperature and body size significantly affected respiration rates in … They are pretty much impossible to tell . Gray Treefrogs generally spend the day hiding in indistinguishable from H. versicolor and two species are Piedmont and Mountain regions of our area. Once thought to be single species, recent genetic work revealed H. chrysoscelis to be diploid and H. versicolor to be tetraploid. Hyla chrysoscelis Cope, 1880 Cope's Gray Treefrog. George R.

This is the most common treefrog species in the Gray tree frogs are very small and range in size from 3.8 to 5.1 cm. Hyla avivoca - Bird-voiced Treefrog. Their size ranges from 1-1.5 in (2.2-4.1 cm). Blair (1958a) plotted distinct geographic distributions of two call types across the range of what was then considered H. versicolor. Photographer: Dana Drake. The frog’s scientific name is Hyla chrysoscelis latin for “belonging to the woods” (Hyla) and golden spots (chrysoscelis) referring to the yellow or orange coloration with spots on the inside of their hind legs. It can also be found in parts of Texas and Arkansas (Wright and Wright 1949). Adult H. chrysoscelis have been used in multiple acoustic playback experiments and exhibit phonotaxis towards conspecific cues when selecting a breeding habitat (Swanson et al. environment and activity. variety of wooded habitats but are most common in mature deciduous trill than H. versicolor. are best distinguished by call; H. chrysoscelis has a faster Photographer: Brad M. Glorioso. It tends to become darker when it is cold or dark. They are very similar in appearance to Cope gray tree frogs (Hyla chrysoscelis). Fun fact: Gray treefrogs (Hyla versicolor) are visually indistinguishable from Cope’s gray treefrog (Hyla chrysoscelis) with which they share much of their range. The range of D. chrysoscelis is more southerly; it is apparently the species found in the lower elevation Piedmont and Coastal Plain of Virginia and the Carolinas. Its coloring helps it blend in with tree bark!�It has light colored spots under its eyes and bright yellow-orange on the underside of its thighs. tree holes or other secluded areas and emerge at night to feed trees and are most often encountered during the breeding season, GAP range maps represent a coarse representation of the total areal extent of a species or the geographic limits within which a species can be found. The nominal species Hyla versicolor has been divided into three subspecies, H. v. versicolor, H. v. chrysoscelis, and H. v. sandersi, pri- marily on the basis of skin texture and color pattern. Hyla chrysoscelis (Cope’s Gray Treefrog)is a nocturnally breeding species found throughout the eastern U.S. (Ritke et al. were confused under the name Hyla versicolor. (1.25 - 2 in; 3.2 - 5.1 cm) with large toe pads and granular skin. when they call from vegetation surrounding wetlands. Each of these vertical blue lines represents on pulse of the trill. Species Range Hyla avivoca - Bird-voiced Treefrog. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. We therefore measured respiration rates across a range of temperatures (18.3–30°C) in wild-caught larval Cope's Gray Tree Frog (Hyla chrysoscelis), a species widespread throughout the eastern and southeastern United States. Hyla versicolor can be found in Maine, southern Canada (west to Manitoba), Minnesota, South Dakota, southern Kansas, Oklahoma, the Gulf States and northern Florida. Geographic Range Both gray treefrog species, Hyla versicolor and Hyla chrysoscelis, are native to North America. For Virginia, Ralin (1977) hypothesized that H. chrysoscelis occurs in the southeastern half of the state and H. Cope’s gray treefrogs, Hyla chrysoscelis, from Monona County, Iowa. Two species This dataset represents a species known range extent for Cope's Gray Treefrog (Hyla chrysoscelis) within the conterminous United States (CONUS) based on 2001 ground conditions. But the most noticeable difference between them is their forms of sound. The known range for a species can be used to constrain the boundaries of the species distribution model and in assessments of the conservation status and/or threats within the range of a species. H. versicolor has a harsher, faster call than the low, metallic call of H. chrysoscelis. This has resulted in considerable taxonomic confusion, especially in early reports. Gray treefrogs inhabit a wide range, and can be found in most of the eastern half of the United States, as far west as central Texas and Oklahoma.They also range into Canada in the provinces of Quebec, Ontario, and Manitoba, with an isolated population in New Brunswick.. i>Hyla chrysoscelis and H. versicolor , are common treefrogs in eastern North America and are a cryptic diploid-tetraploid species pair. These treefrogs can be found in a variety of colors, in fact, each individual frog can assume a variety of different colors (comparable to a chameleon). Also sometimes known as Southern gray treefrog. Grant Parish, Louisiana. The two can only be distinguished by their calls. The range of H. chrysoscelis in the southern United States apparently is di­ vided into western (central Texas) and eastern parts by the interposition ofH.
