1982 R.L. Munne Melanerpes formicivorus Poison Oak Hill 12 May 0800, I finally make the long postponed trip up here to find nests. Right away I get lucky and flush a bird from a very low hole in a large Blue Oak at PO Hill #1. The tree was right along the ridge right in the center of the main granary area. I climb up open the hole (a bit uncomfortable) and find 3 babies, (about 4 days old) and 2 unhatched eggs. The eggs differed greatly in size ① 23.5 X 19.4 and ② 25.2 X 18.1 ② Also had a puncture wound, and all contents had been drained out. The other egg was undeveloped. Still Acorns at PO Hill #1, too. PO Hill #2 -- Lots of acorns, surprisingly, in the big Valley Oak on the ridge 200 m above PO Hill #1. No nest found, but a Big Black Oak 30 m NE of the granary, had several tasty-looking holes in it. I will check it again on the way back. No other holes seen on a rather cursory Search. Revolution -- No stores, no birds, nothing going on in what remains of this territory. Post Flat -- A truly impressive number of acorns here, plus, I find the nest that has long eluded Walter A definite nest (adults feeding + brooding) in a large, totally fire-killed Valley Oak 200 m ESE of the granary, along the ridge that forms the S boundary of Post Flat. It seems a bit farther away from the granary than is usual, but I couldn't [illegible] find any other granaries in the vicinity of the nest tree, and it seemed like the birds were shuttling back and forth
