Gray Treefrog by swimming pool

A Cope's Gray Tree Frog seen singing next to a swimming pool. This is an example of an "ecological trap", where an animal's natural responses to cues cause inappropriate behavioral responses to human disturbances. In this case, the frog is mistakenly singing next to a swimming pool, even though its tadpoles could not survive the chlorinated water.

Gray Treefrog showing flash color on leg

You can see the bright yellow flash color on the underside of this Gray Treefrog's leg. The yellow color may distract predators when the frog jumps.

Predator Induced Red Tail in Treefrog Tadpole

Gray Treefrog Tadpoles develop red tails when they smell predators. The tadpole on top grew up in an environment with predators, and so developed a red tail. The tadpole on bottom grew up in an environment without predators, and so does not have the conspicuous red tail.
