1981 R.L. Murme Melanerpes formicivorus Blom one 14 Sept Well we do indeed have a threesome at Blomone. Watching the granary at 0815 I spot ♀649 white/DBlue and old ♂623 Black/Or-black back and looking like a member is good standing. Plus a third bird (♂) which must certainly be ♂492, though I didn't see bands. Birds shuttling back and forth between the big knoll and the granary. No evidence of any of the current 1500 Juveniles hanging around the granary, but I need to check the knoll area. 0930: Great stuff. On the knoll, in the VO's on the north side, I find 1500 J♂677 M/Dblue-Yellow (N) / DBlue actually defending a small area around a small, mistletoe capped VO. I even saw him chase 2-3 times ♂623 his older brother who helped raise J♂677! What a punk! I guess this says something about site-related dominance. ♂677 seems pretty serious. Also saw him chasing a ♂NB. Very strange: there are, of course, a very few storage limbs up here on the knoll. And there are a lot of acorns up here. So who knows? 1 Oct A quick walk by ♀649 wht/DBlue These birds (now just 2?) have started storing! About 30 or so new acorns in the granary ** 6 Oct Group update: ①♀648 is clearly gone, almost certainly returning to her natal territory (wherever it might be), with rejoining ♀650. ♀648 last seen on [illegible], June and I think certainly absent by 8 June, so say ♀648 left group about 5 June ± 0. ② ♂493 moved Blom 2 14 July ±2weeks: Last seen certainly at Blom one 25 June, but was visiting
