Nests can tell us a lot. You can learn the species. You can learn how long ago the bird left the nest. And various other facts. You can learn the species because some birds have unique nests. Osprey nests are probably larger than a big coffee table. Also, Ovenbird nests are two-room domes. Then, how torn the nest is can tell you how old the nest is, and gives you an estimate of when the bird family parted with the nest.And gives you a good hint to when the bird was in the breeding season, and when it wintered (depending when you get the nest). So a lot can be discovered about birds just by looking at there nests.
