Flammulated Owl (Otus flammeolus) The flammulated owl is a small insectivorous neo-tropical migrant of ponderosa pine and mixed forest types. They aze secondary cavity nesters selecting cavities in the largest and oldest snags and live trees available. Foraging of insects is often concentrated in 1-4 acre open patches of mature ponderosa pine on mid-slopes or ridge tops with southerly aspect. Daytime roosting occurs in dense thickets or large trees with a sprawling form. Old growth and mature ponderosa pine, Douglas fir, lodgepole pine, mixed conifer, aspen, spruce/fir, pinyon juniper, hardwood forests. Western Burrowing Owl (Athene cunicularia) Common throughout the west where vacant prairie dog holes are available in prairie regions. Also use rabbit or badger holes. In winter they migrate to southern U.S. and most of Mexico. Main diet consists of grasshoppers, some beetles and moths. Also takes small birds, mice and some crustaceans. Usually found below 9,000 feet, but occasionally higher in elevation.. Not likely on National Forest lands. Peregrine Falcon (PereQrinus americanus) Recently taken off endangered species list because of its recovery. Usually found below 10,000 feet, very rare to 11,500 feet. Nests on cliffs, forages over adjacent coniferous and riparian forests, and other habitats Migrants occur mostly around reservoirs, rivers, and mazshes, but also grasslands, agricultural areas, and other habitats. Feeds mostly on passerine birds and waterfowl. Ferruginous Hawk (Buteo reealis) Ferruginous hawks are found over the western half of North America wherever the combination of nesting sites in deciduous and coniferous trees, rock ledges and an abundant rodent populations occur.. They aze yeaz round residents in Colorado. They prefer habitats of deciduous trees, riparian zones at lower elevations in the foothills and on the plains. Ferruginous hawks prey primarily on ]agomorphs and rodents with a few birds and reptiles taken. Merlin (Falco columbarius) This small falcon is a resident of boreal forests of Canada and Alaska. It is widely distributed in North America but it is uncommon. Merlins prefer open areas to hunt and primarily coniferous forests in which to nest. In winter they frequent open pazkland and prairies with a few scattered trees. Merlins use old nests of magpies and crows in deciduous or coniferous trees, especially along a watercourse. Merlin prey upon small to mid-sized birds, and most birds are captured on the wing. Merlins periodically eat mice, insects, reptiles and amphibians. Osprey (Pandion haliaetus) This large fish eating raptor utilizes forested wetlands along larger rivers, lakes and reservoirs. Ospreys food source is primarily fish, hunting from snags or lazge trees next to water bodies. Ospreys require lazge diameter snags or live trees to build their nests with an unrestricted view. Nests aze constructed near large bodies of water. Ospreys migrate to the southern U.S., Mexico and Central America in winter.
