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 ...
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 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.
Moses Asch. 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 was released on the Folkways Records label as part of its Science Series. By the 1990s, the album had developed a cult following and ...
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. [25]
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.
During the mating season, the male frogs shake the branches where they are sitting to improve their chances of finding a mate by keeping rivals at bay. This is the first evidence that tree-dwelling vertebrates use vibration to communicate. [32] When rainfall is at its highest, a male red-eyed tree frog calls "chack" to get the attention of the ...
