The virus used to infect animals in these studies was a second Vero cell passage of strain NY385-99, originally isolated from the liver of a Snowy Owl (Nyctea scandiaca
) that died at the Bronx Zoo during the 1999 WNV epizootic in New York City (7).
Others identified were red-tailed hawk (Buteo jamaicensis, 6), snowy owl (Nyctea scandiaca
, 2), turkey vulture (Cathartes aura, 2), and red-shouldered hawk (Buteo lineatus, 1).
Earle signed a law protecting all raptors, excepting the three species of "bird-killing" accipiters and two species of owls, the great homed owl and the snowy owl (Nyctea scandiaca

Previous reports of knemidokoptic mange in raptors are scarce and include K mutans in a great-horned owl (Bubo virginianus) (10) and unidentified Knemidokoptes species in a snowy owl (Nyctea scandiaca
), (11) a Swainson's hawk (Buteo swainsoni), (12) and in accipiters in Great Britain." To our knowledge, no Micnemidocoptes mite has been found on a raptor previously and the congeneric, M derooi, was only described once in African palm swifts (Cypsiurus parvus) (4) Another golden eagle identified concurrently with this case was infested with the same mite, based on SEM and DNA testing.
