   Upperparts are dark brown to olive-brown, heavily spotted and streaked with white or pale buff, giving a 'scaly' appearance. Underparts are white, with fine streaking on the breast and flanks, especially in breeding plumage. A prominent pale supercilium extends behind the eye. The rump is white, and the tail is white with narrow dark bars.

5. 5

   Caratteristiche distintive

   Tratti distintivi che separano questa specie.

   Prominent pale supercilium, finely spotted upperparts, white rump, barred tail, and greenish legs. In flight, the lack of a wing-bar and the white rump are key features.

6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles have more uniformly buff-spotted upperparts, often appearing 'neater' than adults. The breast streaking is less defined, and the legs may be duller.

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   Breeding plumage is more intensely marked with darker upperparts and more prominent white spotting. Non-breeding plumage is duller, with less distinct spotting and streaking, and a more uniform grey-brown appearance on the upperparts.

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Males and females are generally similar in plumage, though females may be slightly larger on average. No obvious sexual dimorphism in coloration.

Segni di campo chiave

• Size and Shape. A small, elegant wader with a relatively long neck and legs, and a slender bill. Often appears 'perky' with a slight head-bob.
• Plumage (Upperparts). Look for dark olive-brown upperparts heavily spotted and streaked with white or pale buff, giving a finely 'scaly' or 'spangled' appearance. This is a key distinction from the uniform dark upperparts of the Green Sandpiper.
• Supercilium. A prominent, long, pale supercilium (stripe above the eye) that extends well behind the eye is a strong field mark.
• Rump and Tail. In flight, observe the bright white rump contrasting sharply with the dark wings. The tail is white with fine dark barring, especially visible when fanned.
• Legs. Long, greenish-yellow to olive-green legs are characteristic. The color can vary with age and season but is generally lighter than the dark legs of a Green Sandpiper.
• Call. Listen for its distinctive sharp, high-pitched 'chip-chip-chip' or 'chiff-chiff-chiff' call, especially when flushed.
• Behavior. Often forages actively in shallow water, wading and probing. It frequently bobs its head and tail when standing, though less pronounced than a Common Sandpiper.
