Abstract
Roadside raptor surveys were conducted throughout a 12-month period in the eastern Great Basin of Utah. An index of relative abundance was calculated for each species of diurnal raptor present. Communal Bald Eagle roosts were checked routinely and numbers of eagles recorded.
Bald Eagle numbers appear to be stable, but the numbers of Golden Eagles and Ferruginous Hawks have declined since 1968. This decline is probably due to a drop in jackrabbit numbers. The available data do not allow the development of trends for the other raptor species.
