The long-tailed skua is the smallest member of the skua family we have here in the UK. It is medium-sized seabird roughly the same size of a black-headed gull. They have long streamers on their tails and slim wings. Upper parts are greyish, pale breasts and dusky lower parts. The head has a dark cap and bills are dark too.
These birds breed in the high Arctic and are a passage migrant to the UK. In the winter, high numbers of birds spend their time off west African, Brazillian and Argentinian coasts.
Their diets mainly consist of small mammals, but when at sea this can be small fish, carrion and offal.
