Cuckoo (Cuculus canorus)
Great Skua (Stercorarius skua)
Slate grey upperparts with barred white underparts. Female and juvenile sometimes rufous brown. Male with defined grey breast in contrast to barred white belly, female with diffusely barred chest and throat. Yellow iris and thin bill. Wings and tail long and slender, often giving the impression of a small falcon. Often perches with a more horizontal posture than hawks or falcons, i.e. tail pointing backwards and not towards the ground, and drooping wings. In flight wings are not raise above horizontal plane, and it seldom glides like raptors.
Sound:Song: the well known disyllabic "cuck-coo" with emphasis on first note, and the second note a third lower than the first one. Also a harsh "tchaa tchaa", and a bubbly trill, reminiscent of Little Grebe, uttered by the female.

CCLarge and heavy skua with broad wings and short tail. The white patches at base of primaries are more striking than in the other skuas, and are visible both on upper and underside of wings. Size comparable to Herring Gull, but build more compact. Seemingly black at a distance, but white wing-patches usually visible. Confusion with juvenile Pomarine Skua possible, but body is heavier (not just the chest), wings rounder, bill longer, neck thicker and tail shorter.
Sound:Heard mostly at breeding ground. Short, and dry "kek", when agitated. Also a nasal, slightly mewing "kew".
