(Buteo jamaicensis) During Manual Restraint" by Grayson A.
Veterinarians at the Cummings School campus treat more than a 100 red-tailed hawks
each year, and the decision to euthanize was based on experience and three weeks of observing Haiti, said Mr.
To investigate the effects of handling stress on physiologic parameters in raptorial birds, 8 red-tailed hawks
(Buteo jamaicensis) were manually restrained over a 15-minute period.
There were also 28 species with less than 100 of each type counted, including three barred and seven saw-whet owls and four each of great horned owls, bald eagles, sharp-shinned and Cooper's hawks; 12 red-tailed hawks
(Buteo jamaicensis) were overrepresented, comprising 66% of colonic prolapse cases.
Abstract: Voriconazole is effective for treatment of aspergillosis, a common disease in captive red-tailed hawks
Abstract: Pharmacokinetic data were determined after a single dose of meloxicam in red-tailed hawks
(RTH; Buteo jamaicensis) and great horned owls (GHO; Bubo virginianus).
Objective--To evaluate the effects of dorsal versus lateral recumbency on the cardiopulmonary system during isoflurane anesthesia in red-tailed hawks
Hematologic values were compiled from 71 red-tailed hawks
(Buteo jamaicensis), 54 Eastern screech owls (Megascops asio), 31 Cooper's hawks (Accipiter cooperii), 30 great-horned owls (Bubo virginianus), 28 barred owls (Strix varia), 16 bald eagles (Haliaeetus leucocephalus), and 12 broad-winged hawks (Buteo platypterus).
This study investigated AR exposure and toxicosis in four species of birds of prey (red-tailed hawks
[Buteo jamaicensis], barred owls [Strix varia], eastern screech owls [Megascops asio] and great horned owls [Bubo virginianus]) presented to a wildlife clinic in Massachusetts.
Therefore, 4 additional red-tailed hawks
with no evidence of cardiac disease, similarly anesthetized with isoflurane and oxygen by mask, were opportunistically tested (Table 1).
