Pomarine Skua Taken at  Musselburgh on 23rd August 2018 using Nikon D5200 with Sigma 600 mm zoom lens.  Pomarine Skua. Species : Order: Family: Local names: Stercorarius pomarinus. Charadriiformes. Stercorariidae. Pomarine jaeger Site Of Nest: Food: Plumage: Length: Wingspan: Eggs: Feature: Arctic tundra and islands. Fish, carrion, rodents and small birds. Identification  is complicated due to the existence of three morphs. Light-morph adult pomarine jaegers have a brown back, mainly white underparts and dark primary wing feathers with a white "flash". The head and neck are yellowish-white with a black cap. Dark morph adults are dark brown, and intermediate morph birds are dark with somewhat paler underparts, head and neck. All morphs have the white wing flash, which appears as a diagnostic double flash on the underwing. In breeding adults of all morphs, the two central tail feathers are much longer than the others, spoon-shaped, and twisted from the horizontal. Juveniles are even more problematic to identify. 46 - 67 cms. 110 - 138 cms 2 - 3 Olive Brown. They robs Gulls, Terns and even Gannets of their catches. Voice Courtsy of Xeno Canto
