Behaviors

Barking tree frogs are spring and summer breeders. There is some indication that the barking tree frog may be cyclic with major breedings taking place several years apart. A breeding chorus of barking tree frogs sounds like a distant barking of dogs. The breeding call is a loud hollow sounding “quonk-quonk” much louder and deeper that that of the green tree frog. The barking tree frog often burrows beneath roots or vegetation during warmer, drier periods. Some have been reportedly seen in gopher tortoise burrows, and at the base of and in knotholes of trees. Others have been observed falling from large trees during windy evening storms.

Adaptions

Barking tree frogs are well adapted to life in an arboreal environment. Their toes have adhesive disks that allow them to climb easily on bark or twigs.

Special Interests

The barking tree frog is so named because of it nine or ten syllable bark-like call. It is one of our largest native tree frogs. Little is known about the life of this frog away from its breeding ponds. These frogs seem to be very secretive and appear only sporadically, even on summer evenings when you would normally expect to hear their choruses.

Folklore

Frogs are generally seen as lucky creatures. To have one jump into the house was believed to bode well for the entire household. Rubbing frog skin against any blemish was said to provide a definite cure, but only when the frog finally took it’s last breath dying from natural causes. Some though believed that this would only happen if the frog was speared, then the procedure commenced until the frog died. Because frogs are often seen in great numbers as it begins to rain, they have long been credited as rain-bringers.

Conservation

Because amphibians absorb moisture and oxygen through their skin, they are sensitive to air and water pollution. Habitat destruction also has an effect on these animals.

Jacksonville Zoo History
