Question: Why Does My Bird Hang Upside Down?
I've noticed my bird hanging upside down from his perch quite a bit lately. What does this mean? Is there something wrong with him?

Answer: First time bird owners often become alarmed when they find their feathered friends spending time hanging upside down. The truth is, this is a normal and natural behavior for birds, and should not be a cause for worry.

In fact, an upside down bird can be a good sign. A bird that feels comfortable enough to assume this vulnerable stance is almost certainly a bird that is happy, healthy, and secure in his home. If you find your pet swinging or hanging upside down, you can pretty much assume that he or she is in a playful and content mood.

If you feel like your pet is spending too much time "standing on his head" or otherwise behaving abnormally, the best thing to do is to schedule an appointment with your avian vet to rule out any possible health concerns.
