1976 Walter D Koenig 2 Melanerpes formicivorus Black Oak Hastings Reservation (4 February) Burgess: ① j235 banded and last seen 12Aug75, gone by 5 October, Disappeared ~9 Sept. +1½M ② j 243 " " " " 19Aug75, gone by 5 Oct.75, Disappeared ~12 Sept. +1-2 wks. Note: I did observe an unbanded ♀ on 3 November 1975 but she assumed not was not a group member; thus it is not too unexpected to find an unbanded ♀ here. Whether or not she's the same bird as was here last year, is of course another question entirely, I'm afraid. 23 February 1015 Counted stores: Central area: 768 Side area: 364 {1132} I saw/heard no M.f. here. 21 March 1515. Heard plenty of activity here while at Bianca; an intruder there could also have been from here. I walked by to check stores, and there are still plenty here. 22 March Due to a conflict, #392 and 393, the late juveniles from last summer before they were banded, have had their numbers changed to 396 and 397, respectively. 9 April 1130. Count: central area: 908 side area 408 {1316} At least one bird was sitting in the perch forest. Clearly stores have at least not diminished significantly since February. 19 April 1755. One bird flushed from storage area in passing through, none else seen in/out of holes. 20 April 1605. 6 birds flushed out of central area (out of a possible 7).
