Between-year changes in the wintering sites of Ruddy Turnstones Arenaria interpres: a response to diminished food resources?
 

Burton, N.H.K., Fuller, R.A. & Eaton, M.A. 2005. Between-year changes in the wintering sites of Ruddy Turnstones Arenaria interpres: a response to diminished food resources? Bulletin of the Wader Study Group, 107, 36–39.

Individual Ruddy Turnstones Arenaria interpres have previously been found to be highly faithful to their wintering sites both within and between years. Here we describe between-year shifts (of 64–77 km) in the wintering sites of five birds colour-ringed in NE England. A local population decline following the cessation of sewage discharges suggests that four of these atypical movements might have been a response to diminished food resources. A fifth bird moved to the area with the presumed diminished resources, but then returned to its original wintering site.
