The Bird Voiced Tree Frog is named for its call that people say sounds like a bird whistle.  It appears very similar to the Eastern Gray Tree Frog and the Cope’s Gray Tree Frog but it doesn’t have any orange coloration on their legs. In Illinois, the frog is listed as threatened.

The breeding season starts in April for the southern populations and in May for the northern populations. Breeding lasts throughout the summer. Males will start to call in trees or other vegetation above the water. Females will approach calling males and the males will initiate amplexus. The females will carry the males down to the water and lay her eggs there. The larval phase of the frogs takes just a month.
