1980 Walter D. Koenig 21 Melanerpes fomcicivorus Plaque (3 October) found quite a few newly stored acorns, all of which have most likely been stored within the last several days. The oak they were harvesting from is one of those that I've been getting samples from. Actually, I soon discovered that the tree I've been getting the samples from is immediately adjacent to the large bunkhouse live oak. 8 October The birds are now quite active and busily storing. Besides the live Oak at the bunkhouse, considerable harvesting from the 2º tree (Valley Oak) was taking place. After watching them take several from there I went over and took a sample of 4 to weigh and analyze. 17 October 900. Counted stores: Plaque tree: 533 2º tree: 59 Tel pole: ~125 (holes are almost all filled with acorns, as they were last year). 14 November 1400. Counted stores: Plaque tree: 1700 2º tree: 187 Tel Pole: ~250 Just about everything is full here, some areas more so than I can ever remember than being in the past. The roost cavity in the tel. pole is completely stuffed; many acorns are stored low in the Plague tree in bark that may never previously have been used. These birds have been busy! I also took a sample of acorns - about 50 - mostly from the Plague tree and about 20 from the Telephone Pole roost hole. 21 December Saw 3521 plus at least 2 others over at MacRoberts.
