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 ...
Mating activity of grey foam-nest tree frogs typically occurs at night from October to February in south-eastern Africa's wet summer months. These frogs choose to mate in arboreal settings, as they create their foam nests in tree branches overhanging bodies of water.
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.
Males produce both advertisement calls, long-range calls that signal a male's position to other males and to attract females, and courtship calls, short-range calls that are directed toward nearby females to inform them that the male is ready to mate. [20] A male, spring peeper with its vocal sac inflated as it performs its mating call.
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.
Frogs produce two types of calls that most experiments tend to focus on, which are release calling and mating calling. Only the male frogs are able to produce mating calls to attract gravid female frogs. When male and non-gravid female frogs are clasped by sexually active male frogs, they produce a release call. In the leopard frog, there are ...
When animals choose mating partners, traits such as signalling are subject to evolutionary pressure. For example, the male gray tree frog, Hyla versicolor, produces a call to attract females. Once a female chooses a mate, this selects for a specific style of male calling, thus propagating a specific signalling ability.
The male has a dark throat. This frog is very similar to the larger gray tree frog (Dryophytes versicolor), but that species has an orange flash on its hind legs. Both have a whitish square region just underneath the eyes. The bird-voiced tree frog is easily distinguishable during the spring and summer when it gives its characteristic call. [3 ...
