Among the substances produced by birds are the secretions of the uropygial
gland, which may be pigmented orange, red or yellow.
There is a striking morphological diversity of the uropygial
gland in regard to size, shape and the presence or absence of the tuft of feathers (Jacob and Ziswiler, 1982; Johnston, 1988; Montalti and Salibian, 2000).
Additionally, the physical examination revealed a mildly distended coelomic cavity and an enlarged, fluid-filled uropygial
In 1 report, a methicillin-resistant S aureus was isolated from the uropygial
gland of a Congo African grey parrot." In this case, the inciting lesion was thought to be caused by a fall; however, evidence suggested that the bird may have been irritated in the area before the event.
Vitamin [D.sub.3] precursors are present in uropygial
(3) It can also manifest as localized infections of the oral cavity or beak, rhinitis, deep proventriculitis, or, rarely, lesions in the cloaca, skin, uropygial
gland, feet, or pericardium.
This study was performed to determine the histologic structure of the uropygial
gland in an osprey.
Preen oil may be important for the plumage condition of birds that possess a uropygial
gland, as well as for waterproofing, in some avian species.
In birds, adenomas have been reported most often to arise from the pituitary gland in budgerigars (17,18) but have also been described to arise from the uropygial
gland, pancreas, thyroid gland, (19) and kidney.
In the other described cases, the skin on various body areas near the beak, uropygial
gland, thigh, and neck were affected.
The chapter further describes specialized adnexal structures, such as the uropygial
gland and feathers.
(9,11) Anatomic locations of squamous cell carcinoma described in captive and free-ranging birds include the tongue, pharynx, gastrointestinal system, uropygial
gland, and upper beak as well as the skin of the head, eyelids, neck, chest, wings, and legs.
