Provide artificial nesting sites for raptors Bird Conservation

A small study at a reservoir in Arizona, USA (Grubb 1983), found that a bald eagle Haliaeetus leucocephalus pair used an artificial nesting structure in the breeding season of 1978-9, but failed to fledge any chicks. The structure consisted of a tripod of aluminium pipes supporting an existing nest which had failed in 1976 (when it fell in the water) and 1977 (when it was blown down in high winds). The nest was thought to have failed due to thin egg shells.
