Or, on cloudy, cooler days, it can darken to retain warmth. On winter days it can dull itself to gray for blending into its winter home - a burrow in the ground for hibernation. Flashy yellow is its choice when calling for mates. When night falls, it seeks insects to eat. Because lights attract insects, these opportunistic hunters hang out nearby, waiting for an easy meal.
Green tree frogs like to sing in damp weather, but also in fair weather before a big rainfall.
Several enunciations are attributed to them - even the sound of a cowbell. They really get going during the mating season. Since a chorus of as many as one hundred males may be calling at different pitches, up to seventy-five calls a minute, it can be quite a concert. The fried bacon frog, cowbell frog, rain frog, green tree frog - they are one in the same, and live here on our island where they make great natural insecticides. Listen for their performances March through October.
