Collins Bird Guide says: "The successful identification of Jaegers in the field requires a lot of practice." Despite my relative lack of knowledge of Jaegers to begin with, I concluded that the first 3 photos were of a juvenile Arctic Jaeger. It is a bit like a dark gull but also looks a bit like a falcon. There are white panels on the wings which are more obvious on the underside than above.

During the breeding season, they feed on birds, small mammals, berries and insects. Outside the breeding season they obtain food by piracy, chasing birds such as terns and gulls until they drop whatever they are eating. The third photograph shows a skua chasing what I believe is a sub-adult Herring Gull.
