Zumwalt Prairie is home to a diverse array of raptor species and includes the grassland-dependent ferruginous hawk (Buteo regalis), swainson's hawk ("Buteo swainsoni"), rough-legged hawk ("Buteo lagopus"), and the red-tailed hawk ("Buteo jamaicensis"). Golden eagles ("Aquila chrysaetos") are a common sight soaring high above the prairie. The Zumwalt also supports important breeding populations of grassland songbirds, including Savannah sparrow ("Passerculus sandwichensis"), western meadowlark (Sturnella neglecta), vesper sparrow ("Pooecetes gramineus"), horned lark ("Eremophila alpestris") and grasshopper sparrow ("Ammodramus savannarum"). Grassland birds are highly threatened and many need large areas to maintain viable populations. The Columbian Sharp-tailed Grouse, which had been extirpated from the Zumwalt Prairie by 1947 is being reintroduced in an effort spearheaded by Oregon Department of Fish and Wildlife.
