Unlike both Arctic and long-tailed skuas, which have pointed central feathers, those of the pomarine are spoon-shaped and are very obvious in adult birds.

Distinguishing this skua from the northern hemisphere Arctic, Pomarine and Long-tailed Skuas is relatively straightforward.

It is especially well known for its bird-life and over 200 species have been recorded at Ogston including Wilson's Phalarope, Sabine's Gull and Long-tailed Skuas.

Two birds swooping through the air at tremendous speed caught our eye, and we watched spellbound as a pair of long-tailed skuas gave a tremendous display of aerobatics before settling on the tundra not far away.

The Pomarine and Great Skuas' mitochondrial DNA (inherited from the mother) is in fact more closely related to each other than it is to either Arctic or Long-tailed Skuas, or to the Southern Hemisphere species.
