E.M. Brock 1957 2 Stercorarius pomarinus Atkasuk, Mead River Coal Mine, Alaska June 9 at 4:45 2 pomarines were seen circling the Atkasuk village June 17 A nest was discovered on an island surrounded by shallow water just west of the first large lake south of the coal mine. At first a pair of jaegers were noticed, then I noticed both birds going into the broken wing act. I walked towards the area where I first saw the birds take off from. Both birds took flight and made vocal complaints about my presence, then they started "dive-bombing" me, coming very close to my head. It just so happened that at the same time they were disturbed by a dark phase jaeger which they both warded off. There were two eggs on the nest - dark green with dark brown markings. After I had retreated about 300 yards from the nest, the birds returned to it. On my return to the warigan, as I passed by the coal mine, two jaegers flying just after a dark phase jaeger, were seen overhead. They flew to the locality forementioned and were therefore probably the same birds.
