It occasionally hoots Grid 2, by Similisian building, Pt Barrow Alaska 12 June 0910 air -1,0 region mixed flock (8+9) of 8 pectorals feeding in recently erupted pond area of berry Artotila. 1025 - considerable melanotos 8 activity since I began working quite close 8 displaying in (7,0)-(7,2) region. 1025 - 8 pect. in (3,0) region flew toward me, this 'scroton hanging'; flew up to (9,1) shooting above pond at (9,1), began to land but fluttered on a few meters to supplement Dunlin. Pect hooted, landed in now standing there. the inflation of its pectoral sac forces it breast feathers to stand out, revealing the dark basal areas of the shafts + causing a distinct pattern to be formed around the base of the chest, in which the demarcation between upperlower areas is already sharp [illegible] (or whatever) It appears that this fellow has a display mound, a ridge, in (9,1), just to W of 9.1 stake along road 9,1 1050: 8 in (7,10) unit another pectoral display mound. 8 near leg. 8 swooped past me displaying within 10'. As it hoots the bird jerks as the bill opens producing a striking head movement and yanking the neck thrust arc. It continually jerks up and back at 3/sec twice per second as is the hoot oscillation 1108 - in (9,0) region: again 8 and supplementing Dunlin: the alpine 8+q were extracting when 8 flew in upon them, chasing them off.
