two days. When heat and swelling disappear after 8 to 14 days, the 
bandage is removed permanently and the bird is still confined in a 
cage. The joints may then be painted with tincture of iodine. 
Cases that do not recover in three weeks may be regarded as hope-

seldom fly again and their future usefulness is limited to breeding. 
BUMBLEFOOT 
Bumblefoot is a suppurative condition of the feet of walking 
birds. It consists of an inflammatory condition involving the burse, 
tendon sheaths, and tendons of the foot. It is reputed to occur most

The diseased feet are swollen and hot to the touch. In extreme 
cases the swelling becomes so large as to interfere with locomotion.
