1981 R.C. numme Melanerpes formicivorus 1800 1 Sept I'm fairly certain that both J695 + J696 are in full blown ♂ plumage. Geez, isn't anybody going to produce ♀ this year? Interesting, we have almost all ♂ juveniles this year. 30 Sept Watching, 1400. Granary census on back. 1500, giving up. Couldn't see birds well at all today. Only ♂561 yellow/Bik seen at all well, and I watched him store 3 Blue Oak acorns in the hour I watched. Birds also showed a bit of interest in the 81 nest hole and the "Short stub" roost hole, but I don't think it means nest. Whoa, walking out at 1500, I find a ♂ looking out of the "short stub" hole. What's more, he doesn't flush until I climb halfway up the tree. No "baby" noises. Will have to check 1 Oct Watching from Pearson Field 0850, I find a bird in the 1981 nest hole and ♀193 at the hole looking in. Most peculiar. Both leave 0904. 0930, Nothing more, I guess these birds were just fooling around. 15 Oct Trying again, 1400 granary census on back. 1530, Another waste of time. No storing, nothing. Will lump with the 1 hr from 30 Sept, and try in the morning sometime. 17 Oct ♂561, ♀564 and J695 all at Y. J695 is actually a definite ♀ (I goofed). 29 Oct Trying again, 1115. Granary census on back. Yesterday, ♂564 and ♀695 were at Y, but ♂564 is back here today. 1300, almost a complete census: ♂347, ♂476, ♀193, ♂561, ♂562, ♀564, ♀695 all seen well. ⚠️ Only ♂/♀ (J) 696, who was at Y on 19 Oct, not seen. Some storing activity, too. 1 Nov Granary census again, on back at D. 10,
