Green Sandpipers resemble Wood Sandpipers, but are slightly larger and stockier, with darker and less spotted backs, and more uniformly white flanks. Their wings are also wider than those of Wood Sandpipers and have darker undersides. In flight their white rumps contrast strikingly with their otherwise darker upperparts, making them look like a large House Martin. They have grey legs, black beaks with a reddish base, and dark brown irises.
