Abstract

In the present study 6 male swans two black (Cygnus atratus) and four white (Cygnus cygnus), weighing about 5.5-7.5 kg, with bilateral wing sagging and turning out of the wing tips belonging to Parks and Gardens Directorate of Metropolitan Municipality were used as materials. The swans were being fed on daily ration (pellet feed) as well as food residues such as bread, bagels, chips, etc. thrown by visitors. The clinical examination revealed that developing feathers and the tips of the wings of swans were stuck up from its normal position. The wings of the swans were bandaged adjacent to their bodies for one week and their rations were arranged. Angel wings have a high chance of being treated if the problem is diagnosed early.

Genome‐wide association study identified the candidate genes associated with angel wing trait in Pekin duck

“…It affects the carpometacarpus or the joint between the third and fourth metacarpals, which twists outward away from the body, mostly during growth, resulting in wings resembling those of an angel (Shaw et al, 2012). The phenomenon is more common among domesticated birds or wild birds raised in captivity, especially in waterfowl (Lin et al, 2016), such as geese (Shaw et al, 2012), swans (Arican et al, 2019) and ducks (Shaw et al, 2012); however, cases in other species including psittacines, raptors, bustards, herons and cranes have also been reported (Kear, 1973; Naldo et al, 1998; Serafin, 1982; Zsivanovits et al, 2006). Duck is particularly well suited for further exploration in these areas as an economically representative waterfowl and a source of meat, eggs and feathers (Huang et al, 2013; Zhou et al, 2018).…”

“…

The angel wing (AW) phenomenon in birds is considered to be due to excessive pressure on the muscles and ligaments of the wrist joints and the metacarpal bone, leading to malformation of the distal carpal bones and causing the forewings to twist outward (Arican et al, 2019). It affects the carpometacarpus or the joint between the third and fourth metacarpals, which twists outward away from the body, mostly during growth, resulting in wings resembling those of an angel (Shaw et al, 2012).
