Advertisement Calls

An advertisement call is the most well-known call of a frog. It is produced by a male frog in order to attract females during the breeding season and to warn other 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, and sometimes during daylight at the peak of the breeding season.


The advertisement call of the Green Treefrog is a loud abrupt nasal honk or bark, repeated up to 75 times per minute, though it is commonly described as a loud bell-like sound (the origin of the common names "Bell Frog" and "Cowbell Frog").
