Dendropsophus microcephalus, a small tree frog, will produce 100 notes per minute for several hours, requiring up to 25 times more oxygen. [24] Some frogs produce less energetic calls and remain in chorus for longer periods of time with the ability to remain active longer being better for mating success than a higher energy vocal display.

Sounds of North American Frogs is a 1958 album of frog vocalizations narrated by herpetologist Charles M. Bogert. The album includes the calls of 57 species of frogs in 92 separate tracks. The album includes the calls of 57 species of frogs in 92 separate tracks.
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 ...
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.
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 ...
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.
Cope's gray tree frog: Dryophytes chrysoscelis (Cope, 1880) Apparently secure [6] Usually indistinguishable from Dryophytes versicolor without DNA analysis or analysis of mating call [7] Sometimes put in the genus Hyla: Most of Arkansas except the northwest Green tree frog: Dryophytes cinereus (Schneider, 1799) Secure [8] Sometimes put in the ...
The Pacific tree frog begins mating in early winter to early spring. Since these frogs are so widespread geographically, their breeding season is thought to be determined by local conditions. When it is time, the males migrate to the water. They then make a call at the same time. This lures the females to the water, where they mate.
