1982 R. C. Mumme 3 Melanerpes formicivorus Arnold I 27 June J76bl 6cm - DBlue/Lorn seen in passing here, plus many other birds not identified. Later ♀568' wnt-mauve/M and ♂ 679 Bk- CBlue / CBlue - Bk' in the trees up toward Keep Out. Uh Oh, heading back to the truck, I hear a lot of woodpecker baby noises coming from the Valley Oak nearest the turnaround (30 m SE) at the Lambert gate. I investigate & find a very unlikely looking hole in a dead, very shaly limb on the NE side of the tree, about 5 M up. Fortunately, there is a live (but thin) limb next to it, and I climb up, peep in and find 2 (I think! 3 also possible) nestlings ~12-15 days old (no feathers on head to speak of, eyes barely opening, etc). I didn't open it, because this hole is incredibly fragile + shallow. It should only be opened once to band the nestlings, because it may require glue + putty to get back together. It will probably be impossible to drive nails into that limb I should plan to band here on 4 July. It took me a long time to determine that this is Al's nest. It is so close to Keep Out, my first suspicion was that it was KO's nest. After sitting watching the hole for ~2 hrs though, I finally saw a couple of birds fly up from Al to feed the nestlings. Anyway, this was a pretty close call. It would have been very easy to miss this nest, give time, location, etc.
