Bluebirds & Nesting
Bluebird populations have declined by as much as 90% over the last 50 years. They are a cavity nesting bird and with the disappearance of dead trees and wooden fence posts, they lack enough sites to breed successfully. Bluebirds must also compete for nesting with the imported house sparrow.
