Pet Connection: Why is bird going bald?

Q: My African grey parrot is losing his feathers, and my veterinarian wants to run lab tests. I thought feather-plucking was a behavioral problem. What can lab tests tell us?

A: Feather-destructive disorder is a common and complex problem in birds. Among the species in which we typically see it are cockatoos, African greys, macaws, conures, cockatiels and lovebirds. It’s normal for birds to preen, or groom, their feathers to remove dirt or parasites, but when they start chewing the feathers, pulling them out altogether or even mutilating their bodies, the cause can be medical, behavioral or a combination of the two.

Underlying medical causes of feather-plucking can include inflammatory skin disease, low levels of thyroid hormones, liver or kidney disorders or tumors, to name just a few. Among the possible environmental causes are low humidity, poor lighting or changes in the bird’s routine. Behavioral causes include boredom, anxiety and frustration. Sometimes the condition can have multiple causes.

A thorough medical history and, ideally, an environmental and behavioral evaluation are the foundation of a diagnosis, but a complete blood count, chemistry profile, screening for infectious disease, bacterial and fungal cultures, fecal exam and skin and feather follicle biopsies can all provide valuable information. Treatment takes time and patience, and it may not lead to a complete cure. Depending on the cause, medication can help reduce inflammation, itchiness and anxiety. Even if the cause is medical, enriching the bird’s environment is a valuable component of treatment.

The buzz

Three huskies and a cat? No, it's not the latest feel-good movie. Lilo, Infinity and Miko, Siberian huskies in San Jose have become best friends with a rescued kitten and taught her to be, well, a dog. Lilo mothered Rosie, who was found near death when she was about 3 weeks old, and the kitten began mimicking everything the dog did, including walking on-leash. Now the four go hiking, kayaking and paddle boarding with their people.
