1976 Walter D. Koenig Melanerpes formicivorus 1500 (12 July) Furthermore, it means that she is almost certainly ♀ WH/M #260, a ♀ banded at Pump in April, and that she is clearly living here at 1500. A question that I cannot resolve immediately is whether or not she is the unbanded ♀ that used to be here or [illegible] has replaced that ♀. Checking over my notes, I see that I had originally speculated that ♀260 might be the ♀ here when I caught her on 11 April, but that I abandoned the idea when I saw an unbanded ♂ and ♀ [illegible] after seeing a bird flush to here there from 1500. Not convincing contradictory evidence, I should think. Otherwise, I saw an unbanded ♀ here on 22 April. and ♀260, who I confused for ♀42- from 1800 the first several times I saw her, was seen 19 May, 9 June, 19 June, and then 12 July. My guess is that she indeed is the formerly unbanded ♀ here; in any case, that is the conservative route to follow. 13 July 900. A ♀ in the lower sap side; later a bird was seen in tree 1. 11 August 1000. 2 birds heard here; 1, a ♀, seen in lower sap side, then flew up to upper area where she greeted a 2nd bird. 20 August 1015. Several birds (4+) in top edge of the territory here picking acorns from the valley oaks. ♀ WH/M #260 was here; the others were apparently School Hill birds, as I saw ♂ WLL#195, an unringed ♀, and heard a begging juvenile. 22 August 1900. 3 birds in tree 3 proved to be ♂ Pub, ♂ R-W/R/M #194 from School Hill, and ♂ Ad-dark eye, most likely #256 from School Hill; the ♀, at least, flushed up to School Hill. Meanwhile, as these birds merely sat
