There are so many types of birds. Some are large and colorful while others are smaller and less noticeable. In any case, they are all part of the animal kingdom and have been around for about 150 million years. There are also many different kinds, habitats, and migration patterns for birds to follow. Once beloved by humans, birds have now become a nuisance in society. They are a nuisance not only because of their noisy calls, but also because they can damage our cars and homes.
