1977 Walter D. Koenig Melanerpes formicivorus 1500 Hastings Reservation (17 July) presumably "following" the older School Hill birds who had previously moved there. Seen at 60th School Hill and 1500 on "several" dates between 12 Oct. 1976 and 18 March 77, when he was last seen at School Hill. Was at 1500 prior to and following the 20 March revolution, then lived over at Y for 2-3 weeks following the 20 April revolution there. Returned to 1500 between 9-16 May, and has been there consistently since except for fuddling around at the near end of 1800 during the revolution there. Most conservative route is perhaps -> Moved - watched group about 19 March 1977; Moved as Juv. to 1500 19 March. Obviously this bird could be considered a resident here as early as late December; that he was certainly transitional for a long time. Also, whether or not he really "belonged" to 1500 in March-April (or even December-Jan.) is an unanswerable query. I think the above solution is a fair compromise: he was never seen at School Hill after 18 March so must objectively be moved at least by then; his persistent presence at 1500 after and even before then makes it reasonable to move him then directly. The episode at Y was clearly a side issue and doesn't warrant special consideration other than noting his participation. ♂297. The history of this bird is not so different from ♂296, except that he fed the babies at School Hill on 18 May and was there again on 22 May, whereas ♂296 never returned during the breeding season at all as far as I could tell. Obviously this bird was at 1500 or Y more than at School Hill up to Mid May and as early as 22 Feb, but at least by 4 April.
