Based on physical examination, hematologic findings, and radiographic results, the gyrfalcon
was diagnosed with severe tracheitis, airsacculitis, and pneumonia, presumptively due to aspergillosis.
A white male gyrfalcon
can cost thousands of pounds more.
Two separate virus strains were identified: H5N2 in northern pintail ducks and H5N8 in captive gyrfalcons
that were fed hunter-killed wild birds.
She then describes the characteristics of six species of falcons from North America: the American Kestrel, Merlin, Aplomado Falcon, Prairie Falcon, Peregrine Falcon, and Gyrfalcon
. Many color and b&w photos by photographers Dunlop and Palmer are included, as are illustrations, diagrams, and range maps.
While we rode the bus, we saw nine bears--including five cubs, two moose, tons of Dall sheep, lots of caribou, a wolf, a red fox, a rare gyrfalcon

(Falco rusticolus) survives the winter on a diet of ptarmigan and willow grouse.
The answer certainly surprised researchers at Duke University in Durham, North Carolina, who tracked the diving speeds of a tame gyrfalcon
(JER-falkon), an Arctic falcon named Kumpan.
New techniques of measurement are revealing how a gyrfalcon
sky dives without ending up as a splat of feathers.
