The Barking Treefrog, Hylagratiosa is the largest treefrog found in the state, measuring 2 and a half to 3 inches in length. This spectacular frog is equally as
colorful as the Green Treefrog. The Barking Treefrog is only found in the part of the Pennyrile known as the western Karst Plains. Males call while floating at the surface of ponds or flooded
agricultural fields. Most
breeding ponds are located in open grassy areas. The call, as its name implies, is a barking "doonk" sound repeated 9 or 10 times at 1-2 second intervals. In Kentucky, the
whereabouts of adults outside the breeding season is unknown. These secretive creatures usually breed during a brief 2-4 week period between May to July when the weather conditions are just
right.
