|a Nesting of ferruginous hawks in Washington is confined to the shrubsteppe region in the eastern part of the state. The birds nest in two entirely different situations, either on outcroppings of basalt on the slopes of hillsides and canyons, or on the canopy of Juniper trees. Nests dimensions and materials are described. A nearly complete survey of all available nesting habitat in the state revealed that no fewer than 15 and perhaps 20 pair of adult birds breed in the state. Of these, we expect that 12 or 13 pairs will produce young each year. Dietary analysis revealed that small mammals (pocket gophers and ground squirrels) were the most frequently consumed prey items. Small birds, primarily meadowlarks, were frequently consumed prey by both ground and tree nesters. Insects and lagomorphs were fairly abundant as prey items at a ground nest, while snakes (yellow-bellied racer and bullsnake) seemed to replace them in importance at a Juniper nesting site. Dark phase ferruginous hawks are reported for the first time in Washington State.
