PLANT COMMUNITIES : 
The ferruginous hawk inhabits grasslands, sagebrush (Artemisia spp.)
scrub, saltbush (Atriplex spp.)-greasewood (Sarcobatus spp.) scrub, and
the periphery of pinyon (Pinus spp.)-juniper (Juniperus spp.) and other
woodlands [11,21].  The ferruginous hawk is an obligate grassland or
desert-shrub nester [26,33].  Ecotones between pinyon-juniper and
sagebrush scrub are commonly used by the ferruginous hawk in the
semiarid western United States [11].
