Melanerpes fomincivorus
Road 1
(11 March) from the tree, and >50 others were in the area; nonetheless,
a perusal of their stores revealed only the 1 red marked
acorn seen before. Clearly they have been using the
fallen stores to some extent, however.
Several crows were up in the main granary here
unsuccessfully being harassed by the woodpeckers.
5 April
Counted stores: 538. All in main tree. Things quiet.
13 April
Came by at dusk and found birds roosting in 2 holes in a sycamore
by the creek and down toward Gate from the old nest tree. Saw no
evidence of anybody roosting in the lathalla hole. I'm going to have
to be careful, though- with the old tree down this group's nest may
be hard to find.
17 April
At least 2 RI 우우 (354,180) over at Finch- see Finch notes.
No sign of anybody in holes, but with this business over
at Finch it may be a little while. It turns out that there
are at least 5 holes in the sycamore over by the river; one
of them will probably end up being it.
20 April
$354 plus (probably) others still interested over at Finch- see notes.
25 April
$354, $180 still at Finch.
1715. Walked around, checking out old holes and looking for
whatever. Got no good leads, but I did finally find the birds - 6+
of them, up in the sun on the side of Poison Oak Hill. I didn't
search up there for holes, but I probably should.
26 April
1740. Birds are again in the same sunlit tree up on the side of
PO Hill. Identified were ①♂DBRW#222, ②♀LG-DG/LG-DG#406,
③♀LG-DG/LG-DG #407, and ④♀LD/DP#409. This tree is really
attracting birds - for buds, insects, and maybe sap as well.
