SOUNDS EMITTED BY ANIMALS
The sounds emitted by the tree frog
The tree frog, scientific name Hyla arborea is an amphibian of the familyHylidae. His song is very loud, high-pitched and repeated and is heard hundreds of meters away and is emitted by the male to attract females. The sound is produced thanks to a vocal sac that males have under their throats and which functions as if it were a sounding board. During the mating period, the more males there are in the vicinity, the more frantic the singing becomes.
