Tree frogs grow between less than 1 inch to about 5 inches long. They eat insects and other small animals. Most tree frogs can change color, as a form of defense, but not all. These hoppy little amphibians are a common sight in North and South America. Most people probably hear them more than they see them though. In the early spring and sometimes on mild winter days, some types of tree frogs called "peepers" may be heard around the eastern half of North America.

Peepers are tree frogs just with a nickname. They get this from the noise they make. The males produce high-pitched peeps to attract females. They sometimes form a group of other male's top form a noisy, and distracting group, called a chorus.

Other kinds of tree frogs give their call through most of the summer. They are most commonly heard in the evening, or before it rains in the woodlands. They have a special sense to know when it will rain and sound their call to tell others of their kind it is going to rain. It is kind of like a warning call to tell other frogs to take cover from the rain. They don't take cover though because amphibians (like frogs) spend part of their life on land and other parts in the water. Male tree frogs do the entire calling. When a male calls, its throat swells until it looks like a bubble that is about to burst.

An important feature about this Red-Eyed jumper is that it can change color to blend with its surroundings. This helps protect it from predators. The only thing that doesn't change is its brilliant red eyes, and living in trees. That is how it gets its name.
