Brotherson JD, Szyska LA, Evenson WE. 1981. Bird Community Composition in Relation to Habitat and Season in Betatakin Canyon, Navajo National Monument, Arizona. Great Basin Naturalist (Western North American Naturalist). 41(3):298-309
Birds and their relation to environment were studied at the Betatakin Canyon area of Navajo National Monument. Birds were censused by transect method. Riparian forest and mature pinyon-juniper woodland are the two dominant types of habitat in this area. One hundred and thirty five species of birds were recorded. Differences in the composition of bird communities were more determined by season than habitat. Table 1: Major habitat types along with their total number of bird species, total densities and diversities. Table 2: Perching sites of birds from the spring-summer census of 1977. Pinyon pine and Gambel oak were the popular perch sites. Table 3: Bird species grouped by cluster analysis of niche overlaps.
