1983 Walter D. Koenig Melanerpes famicivorus 1500 (14 May) nearby. (It had possibly hatched.) No sign of the plugged egg (the recorder is showing a constant 19.+ degrees). I climb the nest: it is indeed empty; the thermocouple is caught inside still, buried in the woodchips. Checking the record, I discover the record fairly normal looking at least through 1000 this morning; at that point there is an odd ½ hr + break, followed by some short jumps, until at 1130 the temperature went down to ~190°C and stayed there. So: whatever/whoever did it, it was a diurnal beast. Another Acom Woodpecker? This possibility is particularly intriguing if one of the babies had hatched, as hatching is a time that a fair number of odd disappearances have occurred over the years. In any case: the nest has failed, under odd circumstances. The incubation record is nonetheless virtually complete. 5 June 1600. Counted stores: 140, all in Main tree.
