The gray treefrog (Dryophytes versicolor) is a species of small arboreal holarctic tree frog native to much of the eastern United States and southeastern Canada. [2] It is sometimes referred to as the eastern gray treefrog, northern gray treefrog, [3] common gray treefrog, or tetraploid gray treefrog to distinguish it from its more southern ...
The barking tree frog is known for its loud, strident, barking call. It may also utter a repetitive single-syllable mating call. The calls of the barking tree frog sound like a church bell and have been described as "tonk" and "doonk". [6] It has been known to chorus with other frogs of the same and similar species.
Cope's gray treefrog [2] (Dryophytes chrysoscelis) is a species of treefrog found in the United States and Canada. It is almost indistinguishable from the gray treefrog (Dryophytes versicolor), and shares much of its geographic range. Both species are variable in color, mottled gray to gray-green, resembling the bark of trees.
The album developed a cult following [15] [16] and by the 1990s, college radio stations were featuring a frog "call of the day" from the album. [10] In its October 1998 issue, CMJ New Music Monthly named the record its Weird Album of the Month, noting that the barking tree frog's hypnotic chirp "wouldn't sound out of place on an Oval record".

For the Concave-eared torrent frog (Amolops tormotus), they produce sounds in the ultrasonic range. [8] Three areas that are highly involved in frog calls are the preoptic area, the medulla-midbrain junction, and the medulla-spinal cord junction. The preoptic area is important in order the frog to initiate mate calling.
Tree frogs typically have well-developed discs at the finger and toe tips, they rely on several attachment mechanisms that vary with circumstances, tree frogs require static and dynamic, adhesive and frictional, reversible and repeatable force generation; the fingers and toes themselves, as well as the limbs, tend to be rather small, resulting ...

Male Dendropsophus microcephalus calling. Sexual selection in amphibians involves sexual selection processes in amphibians, including frogs, salamanders and newts.Prolonged breeders, the majority of frog species, have breeding seasons at regular intervals where male-male competition occurs with males arriving at the waters edge first in large number and producing a wide range of vocalizations ...
