1981 R.L. Mumme Melanerpes formicivorus Road 3 (7 Aug) a nearly complete census, only Juv, 655 not seen. I also got another hint that J709 >7 J710, as J709 charged right past J710 to be fed by an adult, with no protest from J710. End 1030 (0930) whoops, J655 shows, so Complete Census - 5 adults, 6 Juveniles (J707 is of course, gone). 28 Aug Start 0735. Lots of strange goings-on when I arrive. Seems like one or more intruders were hanging around on the periphery. I heard garricks on a couple of occasions and an occasional cheese in the granary area, though it was never able to ID any intruders. The residents here were all quite active, unusually so; 9265 was especially hyped up. She was flying to other group members, tail-raising, open-wings makes the works. 0820, things calm now. 368 harvests a BlackOak green acorn (presumably), and works it in the VO. J710 begs from 368, 368 feeds J710. Well, complete census: 5 adults (368, 368, 9265, 5537, 6618), 6 Juvs (634, 655, 656, 708, 709, 710). And Believe it or not, it looks like J634, J635, and J656 have all acquired adult male plumage. White eyes, look glossy, etc. They certainly should have molted by now, so I can only conclude (tentatively) that they are 8♂. 0920, very quiet now. I did see One juv. dominance interaction, J656 > J709 (very mild), but nothing else. End 0915. 16 Sept A walk past 1500. No body in any holes. No birds period. These guys appear to be finally out of acorns, which probably explains why no birds are around.
