J.P. Myers 1975 Journal IBP area 11 August (cont’) Pluvialis d. — saw 3 all afternoons, a pair w/its chick. This was especially frustrating because the express purpose of the afternoon outing was to compile more Pluvialis arcticus points (I finished melanotus this am). Other spp. of shorebirds are about now from the tundra. During the afternoon trek I wandered W from the Smithsonian building as far as the Barrow slough, then cut S from there to North Lake. In doing so I traversed a considerable diversity of habitat. Circio 3 12 August 0900 in a moderate and increasing southerly wind I began cursing Circio 3. With the shift in wind direction the temperature soared to a balmy 38° — it is incredible what difference there is. Cloud cover 80% and decreasing, although intermittent rain drops pelted. (We once hailed upon earlier in the am). And with the southerly wind have come immigrants: thousands of Calidris flew by me during the morning hours. That is no exaggeration. As can be seen from the census totals, melanotus appear to be on the move as well. I identified no adult QP — no one on the grid is protecting chicks any longer, and all the birds I was able to see well were juveniles. The quail j’s were moving alot in flocks + small groups, making counting somewhat difficult. I was conservative in counting, and made fair sense of who was whom + where they might have been on my last pass day. Circio totals: al. 25 alpina i 3 melanotus j 0 16 fulicanus j 2 3 The alpina are also obviously up to something. Indeed they are over the entire grid. I find the spp. length adj./juv. ratio enthralling, particularly as it is so long the littoral. (Ask RL); the adult alpina were foraging in all micro-habitats, including low peat/ash stuff, although they appeared to be more common in higher places. During the afternoon I went to transect 3 and worked on intermediate macro-habitat characterization of the transect units. Nothing remarkable of a botanical or ornithological nature happened.
