coniferous forest), and montane coniferous scrub. Nests are usually on the Bound, occasionally in a shrub, and are well-concealed by surrounding tangles of vegetation. It feeds primarily on insects in summer and on seeds of weeds and some gasses in winter. Found below 11,500 feet in elevation. .During breeding season found in dense, mature spruce/fir, less often in Douglas fir. Winters in ponderosa pine, Douglas fir, pinyon- juniper, riparian forests, scattered conifers. Fox Sparrow (Passerellaa iliaca) Inhabits edges and thickets of deciduous (aspen, willow) and coniferous (spruce, ponderosa pine, lodgepole pine) forests. Prefers willow streams and beaver ponds. Feeds on insects by scratching in fallen litter and eats seeds. Dense shrubby undergowth, including riparian willow, undergowth of deciduous or coniferous forests, scrub, woodland thickets. Baud's sparrow (Ammodramus bairdii) A prairie land species that is considered a migant in this area. Preferred breeding habitat of the Baird's sparrow is native grassland, particulazly extensive mixed•grass prairie, and local pockets ofwet-meadow zone or tall- gass prairie that aze situated in lowland areas along the periphery or prairie ponds and lakes or along intermittent streams. Fall migation occurs in Septemeber and October Black Swift (Cypseloides niter) In Colorado this species is most common in the southwest counties of Gunnison, Montrose and Delta. Nesting occurs on steep cliffs neaz or behind waterfalls. Foraging for insects occurs in open areas, presumably often near wetlands or meadows with high insect populations. Found up to 14,000 feet. Forages over all types of terrain. Purple Martin (ProQne subis) Population breeds from southern Canada to northern Mexico, but populations within this range are small and scattered. Birds nest in natural or woodpecker created cavities in tree trunks. Large aspens adjacent to parks, lakes, wetlands or meadows are preferred. Feeds over open grassy azeas or over water. Colonial, but strongly defensive of individual nest sites. Insectivorous, catches prey while flying. Found azound or below 10,000 feet. OId gowth aspen, mixed aspen/ponderosa pine or Douglas fir, deciduous riparian woodlands, bums with snags especially when near water and open foraging azeas. Pygmy Nuthatch (Sitta pyPmaea) The pygmy nuthatch is most often associated with mature ponderosa pine stands, but use sub-alpine forests, lodgepole pine and aspen. In all forested ecosystems, this species nests in natural or woodpecker created cavities when available. It may also excavate its own cavities when other cavities are not present. Food is mainly insects, which is gleaned from bark. Remainder of food is conifer seeds. During poor cone crop years it switches from pine to spruce fir seeds. Lewis' Woodpecker (Melanerpes Lewis) The three-toed woodpecker is distributed throughout the forested regions of Colorado. Primary habitat is spruce-fir forests, but the species may also inhabit ponderosa pine, lodgepole pine and mixed conifer stands. The basic habitat requirement for three-toed woodpeckers is mature and old gowth forests with abundant snags for foraging and nesting. Snags used for nest cavities aze usually at
