1976 Walter D. Koenig Melanerpes forficivorus MacRoberts Hastings Reservation 4 June 825. Flushed one bird from the storage tree, who flew and landed silently somewhere in the forest between there and the knoll. Now watching from the hill. 837. Pub in storage tree pecking at holes. 839. 9 flew to blue oaks just toward knoll, greeting another bird. 841. 9 162 in storage tree hawking. Pub here hawking also. 842. Both gone. 855. Both back again 915. Now both gone into forest again. 925. My distinct impression is that the patterns shown here indicate that this group is not breeding, and the reason is that the adult 9 is gone, having left only the adult 9 and her son from last year, a pairing which I suspect is non-viable. Activity is clearly being split between the storage tree and the mostly uncharted forest between there and Blon Knoll, a small but hard to watch area without holes to my knowledge. In any case, both birds show up, often simultaneously, at the storage area to flycatch or sit and there is no indication that they are saving what they catch or taking it anywhere in particular; surely incubation is not in progress unless, of course, that's where the 9 has been the last several weeks. 8 June 930. Watching 935. Some calls heard. 937. 9 came to storage tree briefly to chase away a Mourning Dove, then flew down into forest toward Blon Knoll. 950. Pub in storage tree again; moved acorn, then began hawking. 1000-1030. Pub in storage tree, mostly sitting and preening. A 2nd bird heard. She seemed in no hurry to feed anybody or get anywhere.
