Dryophytes gratiosus is the largest native tree frog in the United States, acquiring its name from the raucous and explosive call. [4] It is 5 to 7 cm (2.0 to 2.8 in) in head-body length. [5] It is variable in color, but easily recognizable due to the characteristic dark, round markings on its dorsum. Individuals may be bright or dull green ...
They are among the first frogs in the regions to call in the spring. [35] Unlike A. americanus and P. feriarum whose call activity is dependent on seasonality, 63% of variance in P. crucifer call is explained by temperature. [6] Calling rate can be modified by interactions among neighboring males, which tend to alternate calls with one another. [6]
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 was featured ...
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 three movements for their sound production. First, there are body wall contradictions to serve as a way for the intra ...
The cre-ek call can be quite loud and can thus be heard from very far away. Males also produce a "dry land call", a long cre-ee-ee-eeek, that can be heard anytime in the year except during the coldest and driest periods. Pacific tree frogs are the most commonly heard frogs along much of the West Coast of the United States.
The Appalachian mountain chorus frog has a unique call. It is a faster, higher note, and holds a distinct quality and form. The repetitions are quicker and the pitch higher. It resembles the call of the Pacific chorus frog rather closely but is less clearly two syllabled. When a whole chorus of them are heard, one can tell them apart from other ...
The upland chorus frog (Pseudacris feriarum) is a species of chorus frog found in the United States. It was recently separated from the Western chorus frog (Pseudacris triseriata), being identified as an individual species rather than a subspecies. They are a rarely seen species, but their calls are frequently heard soon after rains in the ...
Frogs of the same species generally prefer local calls, which are calls of other frogs located geographically close. One study demonstrated that the basilar papilla tuning is different among Northern cricket frog females from three different populations (Bastrop, Austin, Indiana), with Bastrop frogs having the highest tuning and Austin frogs ...
