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.

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.

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
