Avian Community Structure Along a Mountain Big Sagebrush Successional Gradient
Abstract: We compared vegetative structure and bird communities among 4 successional states in central Oregon representing a continuum from 1) postburn grassland, 2) mountain big sagebrush—Idaho fescue ( Artemisia tridentatA—Festuca idahoensis ) shrub—steppe, 3) sagebrush—steppe—juniper (...

Species richness, evenness, and diversity of bird communities were highest in old‐growth and mid‐successional juniper (22.9 species/transect and 23.6 species/transect, respectively) but lowest in the grasslands (17.6 species/transect). Bird species diversity was positively correlated with physiognomic cover diversity ( r = 0.74, P = 0.001). Density of breeding birds was greatest in old‐growth juniper (6.6 birds/ha) and lowest in postburn grasslands (3.6 birds/ha) but similar in shrub—steppe and sagebrush—steppe—juniper (6.0 birds/ha and 5.5 birds/ha, respectively). Old‐growth juniper had the highest total densities of both tree and cavity nesters. Mountain chickadees ( Parus gambeli ), Cassin's finches ( Carpodacus cassinii ), chipping sparrows ( Spizella passerina ), brown‐headed cowbirds ( Molothrus ater ), mountain bluebirds ( Sialia currucoides ), dark‐eyed juncos ( Junco hyemalis), Empidonax flycatchers, ash‐throated flycatchers ( Myiarchus cinerascens ), and northern flickers ( Colaptes auratus ) were more abundant in cover types dominated by junipers. Vesper sparrows ( Pooecetes gramineus ), western meadowlarks ( Sturnella neglecta ), green‐tailed towhees ( Pipilo chlorurus ), and horned larks ( Eremophila alpestris ) were associated with grassland communities. Brewer's sparrows ( Spizella breweri ), sage sparrows ( Amphispiza belli ), sage thrashers ( Oreoscoptes montanus ), and horned larks ( Eremophila alpestris ) were most abundant in sagebrush cover types.
