1976 Walter D Koenig Melanerpes formicivorus Y Hastings Reservation 2 May 1140. Went over and checked the nest hole. No eggs yet, but it's obvious that the birds are still building it, as it is probably at least 2" deeper now than when I opened it a few days ago, but is still very rough inside. 4 May 1015. Watching. Birds flew from Y area to knoll. 1023. Now 916 and 1-2 others are sap sucking in the Blue Oaks down from and between the 2 nest trees on the knoll. 1028. All 5 birds together on the telephone pole in the Y (briefly). 1030. They are also apparently sap sucking in the Live Oaks at the creek across the road from the barn. → leaving. Watched at dusk. Birds did not roost up on the knoll, but apparently over on the side of School Hill somewhere (presumably where they'd roost last winter). Concerning the revolution, it seems semi-reasonable that the event was a replacement of the adult ♂, and that ♂22 decided to leave when the ♀06 got to be too much for him (I realize that doesn't make a whole lot of sense). Looking over the capture records, it seems likely that both ♂♂ which were banded at Pump and have now moved to Y are 1st-year birds, and thus not ♂309, the former adult ♂. Unless I can catch the 2 running ♂♂ that are there now, I of course cannot prove or even claim plausibly that neither of them are not ♂309, thus one of them will have to be dealt with as such, whether I believe it or not (I don't). Thus 3 ♂♂ must be added (♂259, ♂261, and ♂401) and ♂22 will have to be purged (hopefully I can eventually See [illegible] 19 April- one (at least) is prob. 1st yr.
