SPECIES IN FOCUS- GRAY TREEFROG (Hyla versicolor) CANADA

         

This arboreal frog is native to southeastern Canada and the eastern United States.  Gray treefrogs are rarely seen because of their amazing colour patterns that keep them camouflaged on bark.  They can actually change their colour from gray to brown to green and back again.  The best time to see the adults is in the evening in June when the males sing (This gives away their location).  Surprisingly these animals are not always in trees, sometimes they can be found on the ground along marshy shores.  The tadpoles have a distictly reddish colouring on the fin (Image below).  The juveniles are bright green.
