JPMjews 1977 Journal Burrow Alaska 15 July (cont'd) Pluvialis dominica now in moulting and occurring in scattered flocks, using habitat similar to years past, i.e. upland meadows, gently sloping creek banks, etc. Decidedly upland in haunts. Nesting birds still linger on in a few places. But the milestones for the day were feeding juveniles C.pusilla and C.bairdii. It happens every year. Pectorals still tutored by S.Weedow lake (see opacent) but Ph.fulicarius not in exactly the same site feeding on what must be the same object. 16 July 0730-1100 on fundra by Coroline Ridge w/ Bonnie Bowens, scouting the area for Dicrostonyx; at least she desires for karyotypic work. We found much lemming sign, most of it obviously from this past winter's pop. The pile of tents was green, certainly fresh. But otherwise there was very little to indicate current lemming activity. The first fog for many days (except yesterday's brief episode) grazed due to 10-15 m. 33° temp brought out the cold, especially with a brisk wind. Birds?: baird + semipalm juveniles, dunlins very b fledge (1-2 days) newly hatched Ph.fulicarius, Parasitic Jaeger chasing birds (juvenile Calcarius); C.melanotos 07:40 in some transect 3 unit along SW side of lake, but reduced numbers. Basically unchanged since yesterday. 17 July 0700-1030 censusing grid. 35°, very light E wind, zephyrs noted. Brilliantly clear until ~0910 when a fog rolled in. But clear again by 1000 with high clouds over < 10%. Pictorial sandpiper density on G2 was SPECTACULAR: GRID 1 GRID 2 C.melanotos ♀ 41 Pluvialis dominica ♂ 2 → !
