Question

Birds live in trees. Squirrels also live in trees, but did you know that some frogs live in trees, too?

The tree frog is not easy to find. This frog can change its colour. On green leaves, it stays green. On a brown branch, it turns brown. Some tree frogs can change from green to gold or blue.

Tree frogs have legs and wide feet. They have sticky (粘性的) pads (肉掌) on the end of their toes. These sticky toe pads keep them from falling from the trees.

Trees frogs can be all different colours. Their eyes are different colours, too. Some have green eyes, some grey. Some frogs’ eyes are gold, and some are bright red.

The sounds they make in spring and summer are different, too. One frog makes a sound like dog barking. Another frog makes a loud noise like a snore (鼾声). There is even a frog that whistles (口哨)!
