1981 R.L. Munne Melanerpes formicivorus LA2 (22 may) the fact that I watched here 14 + 17 May ad never saw a bird in or at the hole, they must have had pretty low nest attentiveness. Anyway, it's a safe bet (or fairly safe) that the clutch size was 4 and hatching occurred today Also looks like only 6611 + 9637 are present here, so a pair instead of an unrelated trio, Too bad. 26 may Checked the nest, 1810. 3 very cold basics, no egg. (I was trying to watch the group from a distance, but the birds refused to go to the hole. The 4th egg I saw was gone. I Suspect that it hatched, + the young died. It seems a bit early to be tossing out eggs, but you never know. Still being conservative suggests that we can't say how many eggs hatched, 17 July Watching at LA2, I see juv 698 metal / blue near the LA2 granary at 0845, before it flies off toward LA2 1100, at LA2 I find J698 eating an acorn. Still a few acorns here 18 July Again i passing 1210, J698 m / blue in the granary. 2 other birds as well, but they both flushed quite early as I walked up, 13 Sept A good census here, starting 0900. 6611 DBlue/Blk/Gran-war Q637 LPink/Blk and J697 (not seen previously) M / Blue- Green Blk-Yellow / Blk looking like he may be in 8 plumage. Birds appear to be gathering green acorns from the far, far side of South Ravine 0940, starting to worry a bit about J698. End 1000. These guys out of acorns. 14 oct Storing has begun! ~100 new acorns (Blue Oak?) in the granary.
