Melanerpes formicivorus
Y
(25 Jan) good to get them banded. The Knoll Set birds do "own" the
sycamore below the Y. One knoll-setter is garricising occasionally,
It might be 8564, or perhaps a NB intruder I thought
that I saw earlier.
Y proper, birds are still harvesting & storing Live Oak
acorns, apparently from the late-ripening tree near the bridge
just below the Griffins house. 8669, 9714, 9NB, 8402 all
seen, but 9668 not yet confirmed. End 1120
30 Jan Successful ambush here at the same hole as 8 Jan, but
all I come up with is 8669 & 9714. Both processed and
released.
31 Jan Strolling down from S Hill, after seeing nobody there, I fi-d
5 birds in the trees right around the Y, 1710: 9668,
8669, 9714, 8402, 9NB. I don't know about 9668. She
hasn't been seen at the Y granary in some time now.
Also, at 1715 she clearly flew up to S Hill (to roost?).
At least some birds were roosting in the 30 Jan ambush
hole (!).
3 Mar I sneak some glances here while looking for Knoll Setters, and
pull off a complete census, 1600: 9668, 8669, 9714, 9NB
all seen well.
4 March Set up an ambush at the same hole as 8 Jan, then had an
extremely successful roost watch. Y birds seemed to roost
about 1800, including the 9NB and another bird in
the ambushhole. Sitting near the Blonquist gate, Ether
turned my attention to the Knoll Set birds, I found
9715 & 9NB in the Valley Oaks 20 m "upstream" from the
