Lob-sided?

Does your budgie hold his head to one side, and walk around himself? There may be a number of reasons for this: Parasitic infections such as toxoplasmosis can induce sever symptoms, such as blindness, head tilt, circling and paralysis. Vitamin E and selenium deficiencies can be a chronic deficiency in adults, and can cause weakness and head tilt amongst other symptoms. Also, an ear infection could be the cause; a bird's ears open near the eyes and are well hidden by the feathers. If you part the feathers, you may be able to see the opening, which should not be swollen or have a discharge. If there is a bacterial infection, the tissues will become swollen and the opening is no longer clearly visible. Without a thorough vet examination there is no way of checking which of these illnesses your bird has, and several possible causes are extremely dangerous indeed. So make sure you get to the vet!
