1976 Walter D. Koenig Melanerpes formicivorus 1500 Hastings Reservation (28 September) 1600. Some occurrence along the road brought 6 birds out and down to that locality. Clearly this is where all the "missing" School Hill birds are. 1630. Birds still out along the road. Before leaving I checked stores, of which I found 3 acorns, mice and green, in tree 1. Obviously whoever is actually in residence there has just begun. 4 October Numerous birds were here when we came to set up the Acorn traps. 6 October 1130. Watching from hide. Numerous birds here. ①♂ LB/Or #195 in tree 1 (School Hill bird). ②♂ ca-Bk/yel ③♂ ca-Bk/M ? (maybe #298?) in tree 2. Yes: #298 (SH imm.) seen storing an acorn in tree 2! ③♀ yel-LB/Bk? in 1. only→③♀ ④♂ Or/ yel (#88??) Yes: ♂ Red/yel #88 (School Hill) storing in free 1. ⑤♂ Or-LB/Or #194 in tree 2. No chasing or fighting at all. There are stores here now; these birds aren't just playing around. ①95 storing acorn in tree 2; 2+ other birds in tree 4 area. 1300. Leaving. These birds are living here, by any definition I can think of. Clearly the "split" of School Hill," if indeed that is what it is, isn't entirely through yet, as at least one bird (♂195) is still findable at either locality. It is a very interesting move, however, particularly in regards to the 1st-yr bird(s) apparently going along with the adults. It will be interesting to see what happens next. ? 1-2 other birds may be here also besides the above 5.
