1976 Walter D. Koenig 23 Melanerpes formicivorus Plague Hastings Reservation (9 August) in the lower area; also present is #157, who arrived and repeated the earlier performance with #22, and a 2nd δ, presumably unring, who was not molested and was higher in the tree. The δ again got pursued out of the lower area where the δ is concentrating and was last seen sapsucking on the smaller limbs in the upper section of the tree, above the main area being usurped by #22. 17 August 1145. δ in sap tree sitting; chased a Nuthatch. 1153. #157 here sapsucking now; δ not in evidence. 1155. δ returned; soft wake given by δ; no direct interaction. 20 August 1800. #157 and δub seen sapsucking in the Live Oak above the labs. A storage limb has fallen from Plague tree, losing about 150 holes. 21 August 1730. #22 and a δ atop Plague; #22 eating a green acorn. 915. Birds are next to the upper barn and past it up Chongo. 924. #157 and a 2nd bird (landed at) the 2º tree. 933. A bird (δub?) landing in 2º tree was displaced. 942. 3 birds just flew from the barn up Chongo; a 4th, again no doubt an intruder, had just headed up beyond the Hastings cabin 1005. Several ub birds found above barn; eating green acorns. 1012. Some of these extra birds may very well be Buckeye birds, as I've seen them fly up and off towards that group. 1018. A little chasing going on here. 3 September 1630. δub and a 2nd bird in 2º tree; 2nd bird with a big green acorn. Both flew to forest by upper barn, where there was at least a third bird. 1637. #157 by upper barn preening. 1850. An ub δ is in the tree just past the woodpile: are these Buckeye birds? 1659. There are now 2 ub δs by the upper barn together.
