Ruddy Shelduck, Amy Lewis

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
