Voice: Call is a short high trill, a little more musical than the Cope's Gray Treefrog, and slower. Pulse rate varies from 17-35 pulses/sec. We have heard them call from May though July. The few records we have are from west Tennessee. In this recording a slow trill versicolor call (21 pulses/sec) alternates with a fast trill chrysoscelis (53 pulses/sec).
Habitat: Outside of the breeding season these frogs are arboreal, foraging in the tree canopy.
Range: The range of the gray treefrogs in Tennessee is not well known. We have only recorded calls that indicate Hyla versicolor in the western part of the state.
