JPIayers 1996 Calidris melanotos NARL, North Slope Borough, Alaska 7 June melanotos 88 setting up today on Grid 1. Active hooting, several intense grosse displays. However area around (0,6) and (1,6) is still confusing: NTS 88 present plus one hooting 8?. Also shade of 9? - at least 6 on the grid. 8 June Grid 2 hooting today- large # of 88 (10+) along with active 8? and uncompletely developed 8? Judging from level of activity it [illegible] could be a good Pectoral year. 12 June the activity of several days ago has waned - a fact made apparent in the last breeding breed run (10-11 June). Also conspicuous today on grids 3 + 2 where Dave + Brian detected fewer than 6/50 ha. (6+6 8?). Very few 8? around also. (W/way 1, attempted to track a 8? on Grid 3 - found myself unable to do so in the weather because of the enormous range of the bird's hooting - over 8ha. What hurts most is the fact that 7-8 June it looked to be a good year, say for the anomalous presence of numerous non-territorial 8? incompletely developed in chest structure. 14 June tracking in earnest. 2 8? on Grid 1, 1 on Grid 2. Both One of them, 7B-1, is quite active in display, according to McCaffrey who trailed it - the other 8 spent clearly all their time feeding in a few discrete spots. It was, in fact, quite difficult to track them because they would feed for a long time each without any display, and then quickly + quickly move to another spot on their territory, separated often 100-200 m distant. Once there, they again resumed feeding inconsistently. McCaffrey's 8?, on the other hand, alternated regularly between bouts of display and periods of feeding. None of them, however, had a 8? on the territory. 8? in fact are quite rare. Occasional one fly by, pursued by local 8?. But travelling 8? appear to move past just as commonly or even more so. They too evoke chaos. 16 June Atkasook 17 June see Journal NARL, N. Slope Borough, Alaska 18 June tracking am. + pm. on grids 1 + 2. Activity increased tremendously on both grids compared to previous day. A new 8? may have arrived on 61 (1978-6). On the other hand, it
