Birds live in trees. Squirrels(松鼠) live in trees. But do you know that some frogs live in trees too? Tree frogs are hard to find because they can change their colour. On green leaves,they stay green. On a branch, they keep brown. Some tree frogs can change from green to gold or blue.
Tree frogs have four wide feet and there are sticky pads(爪垫）at the end of their toes. These sticky pads can keep the tree frogs from falling off.
Tree frogs not only have different colours and markings(斑点）on the skins(皮肤），and their eyes are different too. Some have green eyes, and some have grey ones. 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 a dog barking. Another frog makes a loud noise like a snore(呼噜声). There is even a frog that whistles(吹口哨).
