Collisions of Red-tailed Hawks (Buteo jamaicensis), Turkey Vultures (Cathartes aura), and Black Vultures (Coragyps atratus) with Aircraft: Implications for Bird Strike Reduction

Experimental vacuolar myelinopathy in red-tailed hawks.

Avian vacuolar myelinopathy (AVM) was recognized in 1994 as a cause of wild bird mortality when 29 bald eagles (Haliaeetus leucocephalus) succumbed to the disease at DeGray Lake, Arkansas (USA). The cause of AVM and its source remain undetermined despite extensive diagnostic and research investigations. Two years later, when AVM killed 26 eagles in the same area in Arkansas, it became apparent ...

Fatal pox infection in a rough-legged hawk.

Natural pox infection occurred in a free-living rough-legged hawk (Buteo lagopus) in northeastern North Dakota. Gross, histological and electron microscopic findings were typical of pox infection, and characteristic lesions developed in red-tailed hawks (Buteo jamaicensis) but not in great horned owls (Bubo virginianus) following inoculation with case material. Death of the rough-legged hawk wa...

Ocular Disease Associated with West Nile Virus Infection

Chorioretinal involvement, frequently asymptomatic and self-limited, is common in patients with West Nile virus (WNV) infection associated with neurologic illness. A bilateral multifocal chorioretinitis, with typical clinical and fluorescein angiographic features, is the most common finding, but numerous other ocular manifestations can occur. Diabetes mellitus appears to be a potential risk fac...
