Angel Wing or Slipped Wing is a disease that affects waterfowl, primarily geese and ducks. There are two basic theories concerning the cause of angel wing, both of which may be correct and both suppose the root cause to be overfeeding waterfowl. The first involves too much protein and the second involves too many sugars. Angel wing is not generally observed in waterfowl not residing near humans, and the disease can often be observed in areas where geese or ducks are excessively fed bread. To prevent angel wing, waterfowl should not be fed bread, popcorn or other human foodstuffs.

The disease manifests as an incurable anatomical condition which is acquired in young birds. Due to a high-calorie diet, especially one high in proteins and/or low in vitamin D, vitamin E and manganese, one or both carpus (wrist) joints are retarded in their development relative to the rest of the wing; for reasons unknown, if only one wing is affected it is usually the left one.

Angel wing symptoms include stripped remiges (flight feathers) in the wrist area, or remiges protruding from wings at odd angles. In extreme cases, the stripped feathers may resemble sickly blue straw protruding from wings. In adult birds the disease is incurable and usually leads to an early death as affected birds are rendered effectively or totally flightless. In young birds wrapping the wing and binding it against the bird's flank, together with feeding the bird a more natural diet, can reverse the damage.
