Previous reintroduction efforts indicate that peregrines normally return in 3-4 years and rear their young at the site where they were released. Ongoing monitoring will determine if any of the birds released at Lake Roosevelt return to nest. But to date no one has seen nesting activity or spotted a peregrine with a leg band. If you see a peregrine falcon, please report it an any Park Service office or visitor center. You can recognize a peregrine by its' pointed wings, narrow tail, and quick wing beats like a pigeon's.
Peregrines are about the size of a crow and have black marks that look like a mustache.
They are blue-gray with a creamy white or pink breast and throat and black markings on the lower breast and abdomen. The National park service encourages and supports efforts to reestablish native wildlife species that have been eliminated due to human disturbance. The National Park Service in cooperation with the Washington State department of Fish and Wildlife and the U.S. Fish and Wildlife Service is managing this multi-year reintroduction program at lake Roosevelt National Recreation Area. The Bonneville Power Administration funded the project as part of their wildlife mitigation strategy on the Columbia River Basin. As of 2001 no nesting peregrine falcons are known of at Lake Roosevelt National Recreation Area.
