Long-tailed Jaeger (Stercorarius longicaudus)
Hobby (Falco subbuteo)
Breeding plumaged adults with streamers unmistakable (streamers comprising two thirds of total tail length). Adult plumage shows less variation than in other skuas. No hint of breast band, and transition between pale belly and darker vent very diffuse. No white patches at base of primaries of underwing in adults. Juveniles easily confused with juvenile Arctic Skua, but are more slender. Wings narrower and primaries and tail longer. Juvenile Arctic Skua shows white patches at base of primaries on both sides of wings, juvenile Long-tailed only on underwing, and on first few primaries of upper. Barred rump and tail coverts in juveniles. Flight elegant and buoyant.
Sound:Calls sharp and less full-bodied than Arctic Skua, and not so mewing. Short, double-accented "kew-wev" or short "kerk" in agitation. Also a long drawn-out "keeeeaah", resembling both Arctic Skua and Common Gull.

Small and very elegant falcon, with white throat and rufous thighs (adults). Long, narrow wings and medium long tail. Dark grey above and heavily streaked below. Head dark, with marked facial pattern resembling Peregrine. Tail often looks slightly wedge-shaped. Impressive speed of flight, with acrobatic skills when hunting. Often hunts flying birds high in the air. Slower flight action when hunting insects. Will glide, but seldom hovers (as opposed to Red-footed Falcon). Perched birds shows wing-tips reaching end of tail.
Sound:Varied, but not very vocal. Calls when courting and at breeding ground. Most common sound a high-pitched "tew-tew-tew". Similar to Wryneck, but less pleading. Also a sneezing "ktcho".
