General

Great Skua: Large, heavy-bodied seabird with prominent white patch in primary feathers. Overall color ranges from a light bleached brown to dark brown, but all have a cinammon wash that makes the bird look red-tinged. Sexes similar. Juveniles lack the streaked upperparts of adults and show scalloped fringes on their feathers instead. Great Skua was split into Great Skua and Brown Skua (not in North American range) in 2015 by the American Ornithologist Union.
