Spurting behaviour in wading birds

摘要

Many wading birds, including up to 150 Black-tailed God- wits Limosa limosa ssp. islandica,feed regularly in winter in Emsworth Harbour (50°50'N, 0°57'W), part of the Chichester Harbour complex, a large tidal harbour on the south coast of England. Emsworth is my home town and I have been watching the godwits there for many years, counting and logging the colour-ringed birds and taking photos.
