This is especially true in areas where an adequate prey base is available <br />and natural nesting sites are scarce. The project area fits both of ,these criteria. <br />Raptor species that may be attracted to artificial nesting platforms in the <br />project area include the golden eagle, ferruginous hawk, red-tailed hawk, <br />swainson's hawk, common raven and the great horned owl. The kestrel readily <br />adapts to nest boxes placed on trees or wooden poles. <br /> <br />To improve nesting habitat for raptors in the project area, poles with an attached <br />nesting platform should be installed about one mile apart within the canal right- <br />of-way. The poles should vary from about 10 to 40 feet high. The poles and <br />materials for the platforms should be provided by the Bureau of Reclamation. <br />Labor for constructing the platforms and putting the poles up could be provided <br />by the Colorado Division of Wildlife and our Service. <br /> <br />31 <br />
