Melanerpes formicivorus
Fanny Arnold
HNHR
11 January
1300. Counted stores: 943, scattered among 5 trees here.
I'd give their total capacity at 1100, and probably growing.

3 May → DA → 26 March ± 1 month.
22 February
1250. ①♂ or-wh #835 seen in trees between Fanny Arnold
& Arnold I. At least 1 other bird here also. They're here
eating Valley Oak catkins, which are well out already!
Also here: ②♂ BIK/M #1023; ③♀ or/Bik-wh #834; I think
at least a 4th bird.
The baby (①1023) managed to pull out a Valley Oak acorn that
was somehow still in one of the trees. Mostly they are here
for the catkins, however. This tree is definitely the farthest
along up here, and even here there are only a few oaks flowering.
5 March
1345. Several birds in the "open" area above here again!
One is ♂ wn-or/or ??
1348. ③♂ BIK/M #1023, In same trees as on 22 Feb. ④♀ wh-DB/M #834.
17 April
1730. Finally found the nest here - a new hole very high in
the same tree as last year (near, but worse, than a hole Ron
opened up here a few years ago). They have 3 eggs, 2 of which
looked clean and fresh, one of which was dirty (marked #1).
15 May
Banded the 2 babies here as #1249 & 1250. They are (empirically)
between 18 and 22 days old, but they are a tad young, so
I'd say they're ~19 days old.
21 May
There are stores remaining here, somehow!
