Status Reports on Twelve Raptors
Author: David Lawrence Evans

ISBN:
Category : Birds of prey
Languages : en
Pages : 76
Book Description
Depletion of fisheries due to acid rain may pose a future threat to bald eagle and osprey populations in some regions. Loss of essential habitat has affected declines in the caracara and western burrowing owl and the disappearance of the norther aplomado falcon from the southern United States. Most populations of the ferruginous hawk, marsh hawk, and prairie falcon appear stable; habitat loss is the most critical factor in population changes.
