1982 R.L. Munne Mela-erpes formicivorus Low Hay 16 July Good watch here, 0730 - 0930: 7 dominance interactions! Basically, I saw J772 peck everybody (770 3 times, 771 once, 774 once), and so he is definitely the dominant juvenile. I also saw J770 peck at 774 twice, so J774 is probably the subordinate juvenile. I still lacks J771-774 and J770-771 interactions, before I get a full table. J773 is certainly gone 19 July 0720 - 0920, OK dominance watch. Didn't see either of the two interactions indeed, but I saw J772 peck J771 3 times, and 772 pecks both 770 & 774 once each. 8461 + 9524 seen, but not 9587. 28 July 0550, watching for juv dom. 0750, not very successful. All 4 surviving juveniles (770, 771, 772, 774) plus 8461 + 9524. 9587, however, is missing once again. A ♂ + ♀ NB intruder were here early, but closed out. 16 Aug Counted stores, 0800: 2°g 2 1°g 800 800 TOTAL Doing pretty well, considering the late date. 21 Aug OK watch here, 0720 - 0930: 8461, 9524, J770, 771, 774 all here, but 9587 is now conspicuously absent, as is, surprisingly, the dom. J772. Both may well be gone Also, I got a few very iffy hints about dom. 771 may be dom over both 770 + 774: Both gave way to 771 on branches But by no means conclusive.
