Pomarine Skua

The Pomarine Skua is a rare migrant in Britain, typically seen during the summer months, particularly in the eastern and northern coastal regions. It is most often observed in the vicinity of the North Sea, where it can be spotted from shore or on pelagic trips.
Field Identification Guide
Use these features to identify Pomarine Skua in the field.
The Pomarine Skua can be identified by its distinctive central tail feathers, which are long and pointed, as well as its broad, rounded wings and a prominent white wing bar. Its brownish-grey plumage with a pale belly is also a key feature.
The Pomarine Skua is slightly larger than a Herring Gull, with a more compact and agile appearance.
The male Pomarine Skua has a dark brown back and wings, with a pale grey-brown belly and a white wing bar, and its plumage remains relatively consistent throughout the year.
The female Pomarine Skua is similar to the male, with no significant differences in plumage, although some females may have a slightly more mottled appearance.
The Pomarine Skua's call is a harsh, rasping "kraa" or "kaa", often repeated in a series of loud, screeching notes.
Pomarine Skuas are predatory birds that feed on small fish, crustaceans, and other marine animals, often obtained by harassing other seabirds into dropping their catch, and they are known for their agile and swift flight.
The Pomarine Skua can be confused with other skua species, such as the Arctic Skua, but can be distinguished by its longer central tail feathers and broader wings, as well as its more robust build and darker plumage.
