Stercorarius longicaudus
Family: Skuas Stercorariidae
Appearance: Body similar in size to Black-headed Gull, though mature birds have very elongated central tail feathers. Juveniles have wedge-shaped tails. Beak relatively thick. Pale patch on wings only indistinct.
Size: Length 3541 cm, wingspan 88105 cm, weight 230350 g.
Nest: In a depression on the ground in a dry part of a bog, by dwarf birch trees in marshlands, or on an open arctic fell.
Breeding: 13 eggs laid late May early June, incubated by both parents for 23 days. Fledglings learn to fly within 21 days.
Distribution: Breeds in Finnish and Swedish Lapland. Finnish population estimated at between 100 and 2,000 pairs, varies greatly, due to the availability of lemmings as prey.
Migration: Probably by day. Timing of autumn migration unclear, but in poor years for lemmings may leave breeding areas as early as June or July. Sightings also possible as late as September飽ctober. Returns in May after wintering in the mid-Atlantic and near the Brazilian coast.
Diet: Specialist predator mainly feeding on lemmings, but in years when lemmings are scarce will also feed on young birds, eggs and food scavenged on waste tips or in fishing harbours. May also feed on carrion, berries and insects. In winter practices a form of avian piracy, harassing terns and gulls, forcing them to drop their prey.
Calls: Series of shrill mewing similar to calls of Common Gull.
Long-tailed Skuas breed on arctic fells. They will fearlessly launch aggressive aerial attacks on anyone approaching their nests. They are smaller than the Arctic Skua, and similar in colouring to Arctic Skuas of the darker colour phase, though their caps are darker and more clearly defined against their yellowish cheeks. They have white chests with no dark band. Their middle tail feathers are greatly elongated into a narrow needle-shaped tip. Juveniles tail extensions are only minimal. Juveniles are darker than young Arctic Skuas, and have more patterning on their upper parts. Long-tailed Skuas have dark grey legs, their beaks are greenish brown at the base with black colouring nearer the tip, and they have dark brown irises.

Hello Nuri,
A wonderful image of this beautiful long tailed skua. I like the way it's black cap runs diagonally from mid skull through the eye to the beginning of it's beak. Nicely focused and displaying good eye contact with a tad bit of catchlight. The colorful boulder makes an attractive perch while the blurred BG keeps us focused on the bird. Very informative notes. Well done!!
Ron
