Großer Brachvogel
Compared to the Eurasian curlew, the slender-billed curlew is whiter on the breast, tail, and underwing, and the bill is shorter, more slender, and slightly straighter at the base. The arrowhead-shaped flank spots of the Eurasian curlew also are different from the round or heart-shaped spots of the slender-billed. The head pattern, with a dark cap and whitish supercilium, recalls that of the whimbrel, but that species also has a central crown stripe and a more clearly marked pattern overall; the pattern of the slender-billed curlew would be hard to make out in the field.
