Janich 1953 Stercorarius pomarinus June 3 Point Barrow, Alaska On the Ridge area I noted a raised wing threat display by one bird as another flew overhead. June 4 One dark phase bird in area south of the base this afternoon. Two found this afternoon in steel fox traps on tundra. Each had one leg caught and broken. The traps have been exposed by advancing melt off, likely in the last day or two, after laying beneath the snow over possibly much of the winter. We could not determine what prompted the birds to step into the traps. June 6 In the past two days several birds have been in and about the drum area, and calling is occasionally heard there. At 7:20 a.m. today 3 birds were on the ground. One had its wings raised and the other two stood with their breasts prominently displayed, leaning back a little, standing together about 2" from the other bird that was on higher ground. Then one of the two poked at the other and drove it away. The third bird on higher ground meanwhile had lowered its wings. June 8 Three birds are common inland in the dry lake. Chrowih Lake area, about the same density as in the beach ridge area. I collected one specimen today.
