Arizona Treefrog
Male Calling at Night

Arizona Treefrog habitat Recording Location in Daylight





Advertisement Calls

An advertisement call is the most well-known call of a frog. It is produced by a male during the breeding season to attract females of his own species. It can also serve an agressive function to defend his calling site by warning rival males of his presence. Frogs usually make the calls around bodies of water that are suitable for breeding and egg laying. These calls can be heard during the evening and at night.

Short Videos With Sound

Views of eleven adult male Arizona Treefrogs calling at night from a rain pool in Coconino County, Arizona, with a deafening chorus in the background. Views of three calling males, bothered by other frogs, making a raspy, ratcheting encounter or territorial call. A calling male is swarmed by a bunch of other frogs (presumably males) who begin attempting to amplex each other, resulting in encounter and release calls. It could be that a female had entered the territory and that attracted them. If so, she managed to escape without being grabbed one of the males.
