1979 Walter D. Koenig Melanerpes formicivorus School Hill West Hastings Reservation 21 April 1030. A surprise! At least 2 birds here-①♂ub and ②♀m. Both in this area, hawking on the side up above Gate. 1045. The banded ♂ flew off and greeted a 3rd bird! 1100. Now ♂ub on the far (SW) side along with ②♀ub. Now that I think about this, I bet these are the Westgate birds -♂ub, ♀ub, and ♂58. This makes at least as much sense as there being a whole new group up here, especially given that they have been almost entirely missing from their real territory lately. Also, both these birds finally disappeared by moseying down the hill more or less towards the Gate. I do wonder, however- might they be roosting up here? It might be worth checking. 1600. Returned here and fixed up the old roost hole in the Black Oak, where my cut section had fallen out. 15 May 24 June (Probably 13-14th day) 1330. Nobody seen here in passing. 1750. A big surprise! I flushed a bird from the Black Oak upon arrival, prompting me to go up and check the hole that I've previously opened, only to find 3 still juicy but mostly decayed carcasses of AW babies whose crown feathers were already ~1/8" long and who were thus ~15 days old I'd guess (their primaries were just breaking their sheaths). The soft parts were mostly but not entirely gone, and I'd guess they'd been dead at least a week, possibly a little longer. Thus, they may have died during last week's cold spell (16-17 June) when many of the other nests here failed. In any case, I removed the remains, and am now left to wonder who is living here - the Westgate birds, as I
