Segni di campo chiave

• Size and Shape. Look for a very large, long-legged wader with a distinctive, very long, downcurved bill. It's the largest wader in Europe.
• Plumage. Observe the streaky brown upperparts and paler, streaked underparts. Note the white rump, which is a key identifier in flight.
• Bill. The extremely long, decurved bill is unmistakable and unique among European waders of this size.
• Call. Listen for the characteristic melancholic 'cur-lee' or bubbling trill, especially during the breeding season. This is often the first indication of its presence.
• Habitat. Consider the habitat: open moorlands and wet grasslands in summer, coastal mudflats and estuaries in winter.
