1981 R.L. Mumme Melanerpes Formicivorus School Hill Hastings Reservation 22 Jan A successful ambush in the 1980 (2nd) nest hole, catching ♀604 and ♂86, whose blood we were after. I had to open up the nest hole and pull them out, as both birds were lying extremely low, hunkered down at the bottom of the nest. I thought nobody was home for the longest time. The previous night, one other bird seemed to roost in the old Valley Oak hole, but I saw no sign of anyone else. 25 Jan Start watch 1135. ♀524 metal / shows up, starts sapsucking from Scruggly blue oak at the edge of the field, due east of the exclosure and 30-40 meters uphill from the Valley Oak nest-roost hole, ♀602 also sapsucks. 1220 ♀604 flies to the granary tree, and ♂86 jumps all over her, pecking her hard around the head+neck, for about 5 sec, until she moved off the storage limb. Is he trying to exclude her from the granary? 1340 end-watch No sign of ♂402 + ♀260. Especially worrisome about ♀260, since I saw her only poorly last time I watched, and today I confused BLK-wht/metal at ♀602 for ♀260's whtrm. Black is thought to see in poor light. Could she be gone? whow, 1355, on the way down the hill I find ♀260 ... / m, Not a great look, but good enough to exclude other possibilities. So where is ♂402? 6 March Start 0945. 1030, ♀260 wht/m shows to chase PNB intruder. ♀604 Red-wht/Black, ♀602 BLK-wht/m also turn Yellow/OPink up. 1200. Complete census eve ♂402, ♂86 mauve/mauve OPink/m, ♀523 DBlue-wht/DBlue
