1981 R.C. Munne Melanerpes formicivorus Y (19 oct) no takers in 1½ hr, 0900-1030, but the birds show some interest. I may try some more. Anyway, a lot of 1800 birds on the knoll. ♂561, ♂564 anyway, plus ♀NBs. Again here at 1630, ♂562 war-com/m here too, so a large 1800 contingent ♀695 and J696 also here, and I got the fleeting impression that J696 might actually be ♀ too. All 1800 helpers here, except ♀565. Where might she be? Also here are ♀NB, and ♀664 from Buckeye on the knoll. 28 oct Watching 1210. The usual gang in the Lower Barn locusts, ♀668, ♂669, 2♀NB. Plus ♂402 was visiting here again, but at 1215 I saw him (presumably) make (continuous flight from the locusts to School Hill Storing is in progress! Saw each of the 2♀NB store an agrifolia acorn (gathered from the corner live oak) 1330, The knoll is still in contention. ♂564 and ♀695 of 1800, a ♀NB (perhaps 2) and ♀664 of Buckeye all hanging out here (the ♀NB is not the same as the 2 resident ♀NB). Anyway, they (especially the ♀NB) seem to be defending the knoll area from the Y residents. The small but acorn-laden Valley Oak nearest the corner is particularly contested. End 1340. The knoll birds (♂564, ♀NB) in control of the knoll roost tree, as well 20 Nov Just when I think all the confusion at the Y is over, I find out otherwise. Watching here 0930-1130 I find ① All 4 "usuals" in the lower barn locusts, ♀668, ♂669
