Abstract
A newly constructed Ferruginous Hawk (Buteo regalis) nest was dismantled to determine the species origin, length, diameter and weight of each of the sticks of which it was constructed. Sagebrush (Artemesia tridentata) and juniper (Juniperus osteosperma) sticks composed 75.58% and 23.26% of the total. No significant deviation existed between sagebrush percent composition of the nest and that of vegetation surrounding the nest. The mean size of juniper sticks in the nest differed significantly from those on the ground in the vicinity of the nest. A possible explanation for the inclusion of rubbish in Ferruginous Hawk nests is offered.
