The chemical structure of the pigments in Ara macao plumage

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2001
Parrots (Psittaciformes) harbor unusually bright, non-carotenoid, feather pigments. We successfully extracted and purified a sufficient quantity of pigment from the red plumage of the Scarlet Macaw (Ara macao) for a partial chemical analysis.

Lymphosarcoma with Plasmacytoid Differentiation in a Scarlet Macaw (Ara macao)

Avian Diseases, 1997
A lymphosarcoma in a scarlet macaw (Ara macao) affecting periocular structures is described. Microscopically and ultrastructurally, many of the lymphoid cells had plasmacytoid features. Polymerase chain reaction amplification failed to detect exogenous avian retrovirus RAV-1 in the neoplastic mass.

Metastatic Thymoma in a Scarlet Macaw (Ara macao)

Journal of Avian Medicine and Surgery, 2017
A 49-year-old female scarlet macaw ( Ara macao ) was presented with a mass in the cervical region. The bird showed no evidence of pain or discomfort, it swallowed food normally, and its breathing pattern was unremarkable. Results of contrast radiographic imaging revealed a well-demarcated mass in the right cervical region not related to the crop. After

Blood Biochemical Values of Wild Scarlet Macaw (Ara macao macao) Nestlings and Adults

Journal of Avian Medicine and Surgery, 2016
Blood biochemical values are useful as indicators of disease in veterinary practice and for health assessments of free-ranging animal populations. We analyzed blood biochemical values for free-living nestling and adult scarlet macaws ( Ara macao macao) in southeastern Peru with an Abaxis VetScan VS2 portable analyzer with Avian/Reptilian Profile Plus ...

Bilateral Uveitis and Hyphema in a Catalina Macaw (Ara ararauna×Ara macao) With Multicentric Lymphoma

Journal of Avian Medicine and Surgery, 2016
A 20-year-old, female Catalina macaw (Ara ararauna × Ara macao ) was presented with bilateral uveitis and hyphema. The hyphema initially improved with 0.12% prednisolone acetate ophthalmic drops (1 drop OU q4h for 7 days), but the hyphema recurred after the drops were tapered. The bird subsequently developed inappetance, weight loss, regurgitation, and

INTESTINAL AND BLOOD PARASITES IN SCARLET (ARA MACAO) AND GREAT GREEN (ARA AMBIGUA ) MACAWS IN WILDLIFE REHABILITATION CENTERS IN COSTA RICA

Journal of Zoo and Wildlife Medicine, 2020
Costa Rica undertakes continuous efforts to recover the native population of macaw species through rehabilitation programs for breeding and releasing birds in protected areas. In the summer of 2018, a total of 107 scarlet (Ara macao) and 93 great green (Ara ambigua) macaws were sampled in four wildlife rehabilitation centers in Costa Rica.
