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
