During this month vertebrates continue with lessons on birds. We learn that all birds have feathers. It is fun to discover that it is not flying that makes an animal a part of the bird vertebrate group, but it’s feathers. On different days a lesson will focus on various things about birds, such as bird songs, beaks, parts of a feather, and nests. Children can observe some bird nests on the zoology shelf using a magnifying glass as well.
