Melanerpes formicivorus
Hastings Reservation
(9 November) Purge: 3259. Last seen 13 July. Should have been seen
at least by/on 3 September. :: Disappeared about 8 August ±2wks.
16 November
1045. 816 with acorn in locust. Meanwhile one of the 88 was in a
V alley Oak 1/2 way toward the pond hawking and eating/harvesting
acorns. Several Crows were there too-and I watched one to
actually fly off and then be buzzed by the 8 woodpecker as
he left the area.
Apparently the above tree is another of the big producers this
year, as - lots of Woodpeckers, Crows, and Magpies are vying for its
resources. Florence reports seeing the AW chase several Crows
and Magpies this morning when she passed, some apparently
successfully (before they could grab an acorn). Two birds would
usually gang up on a Crow, but one could successfully
intimidate one if he tried hard enough.
1125. AW are still harvesting from the above Valley Oak (by the teleph)
but no crows are coming by at the moment.
21 November
1200. 816 zooming into the locusts at the lower barn.
5 December
1100. Birds still busy storing in the locusts, harvesting their
acorns from the side of School Hill. No stores in the Valley Oak yet.
