1982 R. L. Munne Melanerpes fornicivorus Upper Arnold 2 9 April Counted stores, 1500 hrs: "2" granary 1050 "1" granary 1100 TOTAL 2150 While counted, ♂681 or/yellow showed up, chasing a rather persistent Nuthatch, and then, in the big VD E of the main granary area, I saw 2 ♀♀, at least one of which was unbanded. Not what I wanted to see, given all the unbanded birds up here. Not absolutely certain if the ♀♀ really belonged here. Unfortunately, it started to rain, so I couldn't hang around. 2 May Walking up here at 1000 with Alan, we find a ♂ looking out of the upper opened hole in the Blue Oak nest tree. Climbing up later at 1215, I find 5 eggs about 5-6 days old, perhaps, I would guess hatching may occur about 9 May, and barring improved information around that date, banding around 31 May. Also, the facts that ① Clutch is small ② Nest is relatively early ③ Eggs are nearly all the same size ④ All indicate that there are probably not two new ♀NB here, but we will have to watch the nest some to find out for sure. 14 May Checked nest: 1420: 4 nice-looking nestlings, with no sign of a 5th egg: Young about 5-6 days old. 31 May Banded-bled 4 nestlings, Juns # 778-781.
