Melanerpes formicivorus
Hastings Reservation
11 January 1545. 2 birds were in one of the Black locusts on the south side
of the barn by the trough; one was unbanded.
12 January 1000. Unbanded in tree next to storage tree, flew to telephone
pole. Stores appear to have diminished considerably - only
a few marked acorns seem to remain.
1605. ♂CB/CB in Live Oak just above road across from lower barn.
His activity not at all clear. (♂#22) [Probably Sapsucking (2/4/76)]
19 January Counted stores: only 50 remain. Of the marked acorns,
I could find only 6. These birds have really torn
through their stores.
At 1650 I finally saw ♂or/R-w/n sitting in the locusts by
the barn by herself.
28 January Only 13 acorns remain in storage.
3 February 1540. I'd heard some calls from over here, so I stopped to look-
at a bird sitting in the large sycamore at the fork, who turned out
not to be a Y bird at all but good old j#192 (♂RW) from School Hill
(where I'd seen her this morning). She flew up to the next
sycamore by the tall telephone pole and sat for a minute or so until
♂or = #16 displaced her; I lost her movement subsequently.
Meanwhile I saw ♂ unbanded #309 eating an acorn in the
locusts & in front of the barn.
1550. ♂ub and ♂DBlue/or = #22 were seen up in the sycamore by
the tall telephone pole together.
5 February 1020. With 3" of snow around, 2 birds were up high in the
pinetrees by the Schoolhouse karit-cutting through as I was
leaving. I watched one for a short time, but he was
apparently only sitting up here and not feeding.
