Ruddy Shelduck
Tadorna ferruginea (Pallas, 1764)
UD
RUDSH
1710
Family: Anseriformes > Anatidae
In some Buddhist countries the Ruddy Shelduck is protected because its colour is said to resemble that of a monk's robes. During migration, Ruddy Shelduck have been recorded flying at heights of up to 6,800 m.
Most records are undoubtedly of escapees from collections, and the situation is complicated by the growth of feral populations in Germany that migrate to The Netherlands to moult; wild individuals from their breeding grounds in SE Europe and central Asia may have occurred, the challenge is in proving it

DISTRIBUTION
There are historical records that may relate to genuine vagrants from breeding grounds in southeast Europe, north Africa and Central Asia, but it is thought that most birds recorded nowadays are escapes from wildfowl collections. Winter records mainly in southern and central England. There is a small feral breeding population the southern half of Britain.
