Abstract :

Point counts of diurnal birds of prey on Boulder, CO, grasslands were performed for three winters and summers and related to the landscape features of the count areas. Counts of the wintering raptors Bald Eagles, Ferruginous Hawks, Rough-legged Hawks and Prairie Falcons were observed to be negatively correlated with the degree of urban development in the area. Findings showed that urban grasslands can support most diurnal birds of prey as long as prey populations are present. However, some species are very susceptible to the degree of urbanization.
