Spotted Redshank is a medium-sized wader that winters in Hong Kong from November to April. The breeding individual is quite eye-catching with entirely black plumage and white dots on the upperparts. In non-breeding plumage, the Spotted Redshank is often confused with the Common Redshank (Tringa totanus) which has similar appearance. Both of them have orange-red legs, but Spotted Redshank has a red base at the lower bill and black base at upper bill, whereas both the upper and lower bill base of Common Redshank are red. The Spotted Redshank likes to feed on mudflat in small clusters, and sometimes even swims.
