Arctic Skua (juv)

Juvenile Pomarine Skua

[Tony Whitehead]

Pomarine Skua

[Richard Schofield]

I'm going for (juvenile) Pomarine Skua, on the basis of width of inner wing, suggestion of double white patch on wing, and two-tone bill.

Juvenile Arctic Skua

[Nick Allen]

Arctic Skua - juv/1st winter. Lacks double wingflash of Pom and isn't brutish/deep chested/broad-winged enough. Too heavy and not front-heavy/rear elongate like Long-tailed - body plumage too streaky too.

[Jan]

I meant immature Arctic Skua. Sorry.

This one is not easy. First thought was a juvenile Black Backed Gull, but the white flash on the wings and small projection past the tail strongly suggests Skua. Only one white wing flash so Pomarine ruled out. I'll go with Arctic Skua.
