Richardson 1937 Barley Camp, Warner Mts., 14 mi. SW Abell, Lake G., Oregon. June 8, 1937 - Collecting and observation were done mostly at the lower edge of the forested area, where sagebrush occupies much space between isolated or small groups of firs or junipers. Such a habitat is probably of particular advantage to certain species of birds: Green-tailed Towhees, breeding typically in sagebrush areas, use the trees as lookout and singing perches; Fox Sparrows may often nest in close proximity to trees (aspens, pines -) though they typically forage in adjacent sage- brush or open areas. Sapewchers drill the Western Juniper often; Sparrow Hawks seem to prefer such habitat, perching or nesting in high, isolated trees; Steller Jays, though found in the forest also frequently pass from one large isolated tree to another and may forage on ground between. Woodpeckers are very abundant and are perhaps the most fully represented group of birds in this region. This may be explained by the variety of trees outing both sapewchers and woodpeckers, abundant insect food's, natural conditions as to dead stumps or trees, a partial combination of Upper Sonoran Transition and Canadian zones, with (apparently) fairly mild climate temperature).
