1982 R.L. Murme Melanerpes formicivorus SOBO 9 March Shamefully, When Alan & E were up here on 27 Jan, I neglected to write notes on the partial collapse of the SOBO granary. The entire N limb fell during Dec-Jan (I would suspect around Jan 6-7, during the big storm). All that is left of the granary is the south limb, with maybe 500 storage holes maximum. Watching from the N side of the granary, from hide, 1030. Darned if there wasn't a bird in the granary, when I walked up, which I didn't see until it flushed. I count ~220 acorns from where I'm sitting. 18 April I stroll down to last year's nest to unfortunately find that the entire nest tree has collapsed. Burner! It means we're back to square 1 as far as discovering where these guys might nest. I flush 2 birds from what's left of the granary at 1300. 26 April False alarm! Not at all hopeless to find SOBO's nest. I stroll up to the granary at 1730, say hello, and I'm surprised to see a ♂ look out of the lower hole, then fly off. I manage to climb up [illegible] assisted by webbing (I don't recommend it! Very hard. Use rope ladder next time), peep in, and find 4 eggs! Yessiree. A nice little hole: Shallow and thin-walled. Should be easy to open. May 2 I checked the nest, propped it up. 4 eggs still, nearing hatching. Hole was easy to open (very thin), but difficult to put back together for that same reason. I would guess hatching in or about 4 May, and banding about 26 April. 8 May would be a good day to check for hatching
