Maclan 1969 Journal (11 June) the morning. Dropped Bill off to sketch shorebirds in Britton's Area. Four Buff-Breasts flew in and performed for us. alpina, bairdii, and pusilla were more dispersed and displaying actively. Was again impressed by bairdii and pusilla displaying over areas only slightly exposed, as if to establish territorial claim, and then landing to feed elsewhere. Walked up to Cake-eater and back. There is quite a bit of continuous exposed ground now. Still small flocks of alpina, while others look as if about ready to lay eggs. Both bairdii and pusilla are abundant. Saw at least 5 white-rumps, and several small flocks of pectorals. 2 pomarine jaegers - 1 of these melanistic. In the afternoon a very heavy but warm fog settled in. Took Bill and Hanes to Britton's Area, then went out to low bluffs just north of Footprint Lake with Tom Caoz and his son. The snow cover there is extensive, although the snow is very slushy. Struggled through it to collect 7 longspurs for Tom to do pesticide analysis. Returned to low, wet area south of FAA to collect red phalaropes for the same purpose (took 6) and
