The birds of the hardwoods are so typical that many of 

 them are not found in any other habitat in the region. They 

 are birds which inhabit the crowns of trees and many of them 

 would ordinarily escape notice were it not for the song. They 

 are the Red-tailed Hawk, Bald Eagle, Hairy Woodpecker, 

 Down\' Woodpecker, Ruby-throated Humming Bird, Crested 

 Flycatcher, Wood Pewee, Least Flycatcher, Crow, Rose-breast-

 Nuthatch and Red-breasted Nuthatch.
