Bin-headed cowbirds which lay their <br />eggs in nests of other birds and are considered parasitic are <br />included in this guild since most of their eggs are deposited in <br />open tree and shrub nests and they feed on the ground. Most <br />cowbirds were observed on aspen-edge habitat. Several of the <br />birds of this guild are low density birds and no differences were <br />found among habitats for any of the birds. American robins were <br />the most abundant species of the guild and although they were not <br />counted on the reclaimed sites, the density was not different <br />(P=0.24) among habitats. Mourning doves, considered a foliage <br />nester though sometimes nest on the ground whey. suitable nest <br />sites are unavailable, were observed on all habitats. <br />Black-billed magpies which prefer open terrain but require some <br />trees for nesting, were not counted on the aspen sites. One <br />pair, which nested in a tree pad, fledged young on one of the <br />reclaimed mine sites. American crows were counted on the aspen <br />and reclaimed sites but not on either of the edge habitats. Other <br />birds included in this guild were sage thrashers, Brewer's <br />blackbirds, and chipping sparrows. <br />1986 <br />American robins (P=0.12) again was the most numerous bird of <br />the guild, but there was no difference in species density among <br />habitats. Collectively, birds of the guild were most numerous on <br />mountain shrub but not different from aspen habitats. Densities <br />on aspen, interior aspen, and reclaimed habitats were not <br />different. <br />Foliage nesters - Aerial feeders: <br />1985 <br />None of the birds in this guild were counted on the reclaimed <br />sites and very few were counted on the reclaimed-edge sites, but <br />the densities were not different among the habitats (P=0.057) at <br />the established significance level. Within the guild, <br />broad-tailed hummingbirds, which feed on flower nectar and small <br />insects, were more numerous on the aspen habitats (P=0.02), but <br />western wood-peewee (P=0.40), willow flycatcher, and dusky <br />flycatcher densities were not different among habitats. <br />1986 <br />Again, none of the birds were counted on the reclaimed sites, <br />but more birds (P=0.02) were counted on aspen and mountain shrub <br />habitats than on reclaimed habitats. There was no difference <br />amono_j,~(~r~c* asn n and reclaimed habitats. Individually, <br />earn wood-peewees (P=0.02) were more abundant on aspen, and <br />
