Melanerpes formicivorus
Black Oak
Hastings Reservation
(8 November) The granaries here are about as full as I suspect they could get!
10 November Finally saw several of these birds (8427, 8320, 8321,
and 8497 for sure; possibly 8426 as well), over on the
knoll by Bianca-LA2. See Bianca notes for details.
28 December 1200. Counted stores: Main area: 2135
Side area: 564
The granaries are really stuffed full here. I noted
essentially no Black Oak acorns at all when I climbed
around to get a sample of stores (I got ~85). (I did
see 1, but that was it). No sign of the birds while I
was here.
