Peregrine Falcon
Falco peregrinus
Habitat: Breeding pairs nest on cliffs and forage over adjacent coniferous and riparian forests. Migrants and winter residents occur mostly around reservois, rivers, and marshes, but may also be seen in grasslands, agricultural areas.
Range in Colorado: Rare spring and fall migrant in western valleys, foothills, lower mountains, mountain parks, and on eastern plains. At the Dinosaur Ridge hawk watch, Jefferson County, 10 were seen in both spring 1990 and spring 1991 (Nelson 1990, D. Nelson, personal communication). Rare winter resident at Monte Vista National Wildlife Refuge, Rio Grande County, and very rare in western valleys (16 records) and on eastern plains near foothills (25 records). At the same time it is a rare summer resident in foothills and lower mountains. There were 58 active nest sites in 1991, 42 on the western slope (fledging 75 young) and 16 on the eastern slope (fledging 16 young) (Craig 1991b). The number of active sites and young birds produced increases annually. Birds have been reintroduced into former nesting sites, and even into downtown Denver.
