Bird nests

So I learned about bird nests from a video I watched. The first bird is called a Humming bird. It makes it's nest by getting fine silk to shape into a little nest and then it gets spider silk to bring it all together. The second one is my favorite it is a bird, oh I forgot it's name but it is awesome it makes it's nest out of mud and grass. It bakes it so it divides it into two parts and they leave a little opening at the ending and then you go threw there and you get to the eggs. It is very smart. The other one is called a cowbird. It lays it's eggs into other birds nests and they let the other birds take care of their eggs. Sometimes the eggs get thrown out but sometimes they actually raise them. Then there is another bird which I forgot its name but it makes its nest on the harbor and out off big twigs and then they have to keep predators off. They have to keep predators off because sometimes they are two lazy.
