1980) Walter D. Koenig Melanerpes formicivorus Buckeye (25 April) and Gwen have failed to see anybody incubate. Thus, I came up, flushing 2 birds from the granary (I possibly from the low hole) and checked the nest hole (nobody in it, however). All 6 eggs were still there, but they are stone cold. So I went up and checked the low hole in the granary, also. It was empty, but in good shape. Thus, my guess is that these birds have abandoned the nest, or, at the very least, are rather nonchalant about incubating. We'd better keep an eye out here, since things are probably not settled yet. 27 April 1915. Came up at dusk to try and see what's up here. First of all, checking the nest, there was once again no sign of activity, thus supporting the failed nest hypothesis. I then returned to the granary and watched. At about 1910, the birds - 4 of them - suddenly appeared. Although they didn't appear to all arrive at once, they were all in the granary within 30 sec. of each other. After a short stint of kanitcuts they assembled together on a limb, each only a few inches from the nest. After a brief tense moment one appeared made a move [illegible] and briefly mounted a second bird, but the mounting was broken up in a flash and all 4 birds zipped off in a very tight pack to a 2nd limb. They all stayed there for another 30s or so until several zipped up to a (hitherto unknown) roost hole. Two went in, a 3rd hung around briefly before flying off in a kanit flurry toward the nest tree area. The 4th stayed out a little longer before going to the roost hole, entering it, and then
