1982 R.L. Mumme 3 Melanerpes formicivorus Y (4 march) big sycamore below the Y, where the birds have been roasting. Between 1800 and 1810, QNB made three trips back & forth between the Valley Oak and the Y granary by the Lower Bard. On each trip, she returned to the VO with an acorn! This amounts to stealing acorns While the owners are in bed. It's very interesting since ① Knoll Set has no granary and no stored acorns, and ② this almost seemed to be an act of intelligent reasoning (dare I say it?) on the part of the QNB. The three acorns, it seemed, were broken up and stored in crevices it bit form, in the Valley Oak. Q715 roasted in the usual sycamore hole about 1805, and QNB followed at about 1820. 5 March SHIT! Ambush here doesn't get the QNB. It was too late. 0550 was not early enough. 0530 is better. Anyway, one bird (QNB) flew out before I got the net over the hole, and all I could get was Q714 again! I'm getting tired of this. But I will probably try again soon... 8 April 1500, I actually see a bird working on the nice East-facing hole in the Blue Oak on the knoll. I climbed up to that hole not too long ago, and found it to be only about 2 inches deep. Indeed, the bird (a ♂: ⑦669?) would have his butt exposed as he pecked at the bottom. 29 April Been watching here casually the last two mornings. The general conclusions are as follows ① The 4 birds are all here: ⑦669, ⑥669, ⑦14, QNB
