Each bird species builds its own special kind of nest. The most common materials used for nests are grasses, branches and feathers. A bird must weave these materials into a nest. Just imagine building a house without cement or nails to hold together.

Another bird is called the weaver bird. 'The weaver bird builds a nest that looks like a basket. The nest is shaped like a pear with a hole in the middle. The hole is the door of the nest.

A third bird is called the oven bird. The oven bird makes a nest that is very solid. The nest is made of mud. The oven bird forms the mud into the shape of an oven and then let it dry in the sun. The sun bakes. the mud, making it very hard.

Not all birds make their homes in branches. Some birds build their nests on the ground, while others bury their eggs under the ground. And some birds do not build nests at all.

So when you look for nests and eggs in the branches of the trees and bushes, remember, that some nests may be right trader your feet.

B．An oven.

C．An egg.

D．A basket.
