1982 1983 Walter D. Koenig Melanerpes formicivorus 1500 HNHR 23 October 1220. Counted stores: Main tree: 845 20 tree: 116 1983 4 January 1445. Counted stores: Main tree: 2011 20 tree: 308 Also took a sample of 35 acorns from the stores, which I froze right away. 2 May 1400. Sacrificed egg #1 (there are 2 in the nest now, only 1 yesterday, so that's the one I used) for incubation monitoring. Everything looks great. I threaded the line through a hole in the bottom of the nest and you really can't tell it's there. So here's hoping. I started the recorder at 1436 PST. 8 May 915. Came down here to see what the problem is - specifically, why the recorder randomly jumps up to 45° and then settles back down. It turns out that whenever the egg moves the recorder goes crazy for some unknown reason. So I put a dab more epoxy on the egg to try and hold the wires more securely. Otherwise the temperatures seem fine, and perhaps a bonus is that we can tell every time they turn the eggs! Also, egg #1 is not developing, of course, but neither is #2. Thus, only the 3rd egg will hatch, apparently. 13 May 800. Eggs not hatched yet; both #2 and 3 did develop. 14 May !1430! Nest failed! Hole empty! The scene: I arrive: no one in hole. Upon beginning to set up the rope ladder, I discover 1 embryo still in a rather smashed egg on the ground below the nest, and a 2nd embryo carcass, somewhat eaten,
