1977 Walter D. Koenig 3 Melanerpes formicivorus Black Oak Hastings Reservation (17 April) 00ub, (2) 8102, (3) 8321, (4) 9320, plus (5) 2ub 9F. 197, the 2nd-year bird, is surely gone. I still think that the 2 9F have replaced the old adult 9F, who naturally was unbanded also. But I'm going to have to catch some of the birds to pin things down any further.-and the roost hole down the hill seems like a pretty good place to start. 28 April 1700. lots of calling brought me over to watch (this area was virtually deserted the last 2 times I walked by since the 17th). There is chasing and lots of wales; perhaps 10- 12 birds altogether, with several loci of activity as usual. I'm having a hell of a time actually seeing anybody, however. 1710. 00ub (just displaced someone?). 1715. 5+ birds rallying in main storage area, inc. 9ub and 3om (#321?). 1725. 3 birds together peacefully in central area: 3ub, 9ub, 9w/yel #102. Perhaps this is another of those attempted crashes (such as at R and Finch a few weeks ago) rather than a revolution directly induced by the disappearance of the 9F. (best way to tell will be, perhaps, to see if extra 9F end up staying or whether only the ( remains). 1730. Hum. 288 (9102 and 9m/DB-yel(n)#321) and 3 9F (at least 1ub) together in main area. 1735. There certainly does seem to be a surplus of ub 9F, some of whom are busy chasing each other. Of course, the 9F aren't helping much- they're friendly to nearly everybody. 1742. There are at least 4 or so ub 9F just nearby, and it's not always obvious that 2-3 of them aren't getting along.
