Pomarine Jaeger (Stercorarius pomarinus)
Spotted Redshank (Tringa erythropus)
Pale and dark morphs. Often difficult to distinguish from Arctic Skua. Adults with broad, spoon-shaped streamers. These are moulted twice a year, so adults lacking these are not uncommon. The dark cap reaches around the bill base and down to the chin. Breast band in pale morph is generally broader and more pronounced than in Arctic Skua, but in some males it is lacking altogether. Leaves an overall more robust and powerful impression than Arctic. Wings are broader than the distance from trailing wing-edge to tip of tail (streamers excluded), while the hand seems shorter. The light patches at the base of the primaries are more obvious, and many young birds shows a characteristic double patch, formed by additional white base of greater primary coverts (like Lesser Spotted Eagle). Rump and vent of juveniles usually boldly barred, in contrast to unbarred back and belly (visible even in dark morph). Streamers never pointed (in any plumage). Flight pattern straighter, and more determined than in Arctic Skua.
Sound:Short "kea" or "ke", and various mewing calls, usually deeper pitched than Arctic Skua. Also a characteristic, laughing and vibrating "kayayayayaya", heard mostly on breeding ground.

Unmistakable in breeding plumage, with all dark/blackish body unique among Tringas. Most birds seen in Europe will probably be in winter- or juvenile plumage, and can then be mistaken for Redshanks. Spotted Redshanks are slimmer, longer legged and more elegant than Redshanks. The supercilium is much more prominent, the bill is slimmer and longer. Most diagnostic is the lack of white wing-bars, and the white sigar-shaped patch on the back. The barring in juveniles reaches from the belly and all the way back to the vent. Often feeds in deeper water than Redshanks, even by swimming and upending.
Sound:Flight call loud and diagnostic, and is often the first sign of the species' presence; a sharp and short, disyllabic "koo-eett", with the first syllable falling in pitch and the second rising sharply. Display call a squeaky, but melodic "krroo-lee-ooo" repeated in cycles. Alarm call a falcon-like "ke-ke-ke-ke".
