Feather Cysts

Feather cysts form when feathers growing below the bird’s skin fail to emerge properly. They then curl back and continue to grow, forming elongated lumps at the base of one or several feathers. Secondary bacterial infection may set in, exacerbating the problem.

Feather cysts usually form at the base of the primary wing feathers, and are most commonly seen in budgerigars, canaries and macaws. They should be surgically removed by a veterinarian.

Swellings near the Cloaca

A swollen area just above the cloaca (the common opening for the digestive and respiratory systems in birds) is often indicative of a hernia. Usually related to stomach muscle atrophy, hernias are difficult to treat and require veterinary intervention.

Swellings below the cloaca may also indicate a hernia or, more commonly, a tumor. Egg-bound hen budgerigars and other birds will also appear swollen in this area, and may strain in an attempt to dispel the egg. Immediate veterinary attention is necessary.
