Melanerpes formicivorus
Hastings Reservation
(30 April) a lot of interest in the '75 nest hole even in the few minutes
I was able to watch them, so perhaps they'll be good to us
all and nest there.
5 May
2005. Birds roosting in the sycamore (the weird hole) and
the Blue Oak in the hole I cut open last year (which
wouldn't be a bad place to nest at all).
7 May
1700. Bird(s) in hole in Blue Oak in knoll again (not for roosting
or nesting necessarily - it's raining and cold out.)
9 May
1100. FWRW#326 and 288 seen on the far edge of the knoll.
By now, 4 birds have recovered all but this tall perch tree
and the sap tree from these birds (presumably #326 and the
School Hill 1st-year birds).
13 May
Birds using both holes in the big sycamore at dusk.
19 May
Monica's last day.
20 May
930. Flushed 1-2 birds up Canyon (School Hill side).
1120. Checked both holes up the canyon: the one in the small tree by
opening my cut and the other by carefully probing with my widget.
Nothing in either.
1430. Watching. 3-4 birds in tree up Gulch along Co. road in
dead limb. Could definitely be a hole there. (≈50m up from main
granary). ♀364, ♂16, and ♂261 there for sure.
No intruders on knoll or elsewhere.
1455. At least those 3 still there. ♂322 also can be seen.
3 together within a foot, [illegible]
1515. ♀ here for sure; others not clear. Went to check
limb; the backside does have several holes, which may
be useable. No birds in any of them, though.
