Numenius arquata
Biggest wader in area. Differs from Whimbrel in longer bill with a more even curve, only diffuse head markings without crown stripes or marked eye-stripe. Note that young Curlews have much shorter bill than adults. Base of bill pinkish. Plumage gives a paler impression than Whimbrel, with paler underwings and flanks.
Song starts similar to Whimbrel, with long wailing notes "kluuueee", but takes on a different ending as it accelerates to an ascending phrase repeated in rapid cycles .
