D.A. Pass E.C. Beggs G.L. Pearson 1975 <p><span>Natural pox infection occurred in a free-living rough-legged hawk (</span><i>Buteo lagopus</i><span>) in northeastern North Dakota. Gross, histological and electron microscopic findings were typical of pox infection, and characteristic lesions developed in red-tailed hawks (</span><i>Buteo jamaicensis</i><span>) but not in great horned owls (</span><i>Bubo virginianus</i><span>) following inoculation with case material. Death of the rough-legged hawk was attributed to starvation resulting from inability to capture prey and to blood loss from foot lesions.</span></p> application/pdf 10.7589/0090-3558-11.2.224 en Wildlife Disease Association Fatal pox infection in a rough-legged hawk article
