Melanerpes formicivorus
New School Hill Hastings Reservation
(3 February)
the 2nd unbanded ♀, different from the one down in the main
School Hill area. It will be interesting to see how complete
the "split", which is gradually forming here, goes.
This takes care of all the birds except #195, who was last
seen last week.
1322. ♂ub and ♀LBRW both in storage tree still. ♂88 flew up over me
to top of field.
1324. ♂86 returned, greeted by ♀, while the juv. sat and squeed
begged just below where he landed.
1325. Juv. still in tree; adults briefly disappeared around the hill:
1328. ♀ eating acorn bit now.
5th Field
A goodly amount of greeting and
contact vocalizations, even when no one new lands, is taking place
here, not unlike the high level of activity one finds in a group having
recently undergone a revolution. Perhaps they have indeed split,
through one or more of the 1st year birds (e.g. #193, who roosts up
here but was just seen down in the main area) may not have quite
decided where their allegiance should lie.
1330. leaving. Burts out of storage tree right now.
1545. jFORW#192 down at Y. See Y notes.
17 March 1650. Walked up to School Hill B area, where there was a notable
lack of any woodpecker activity whatsoever. As an explanatory
factor, the storage tree here was totally depleted of acorns.
Meanwhile, calling was emanating from lower down in
the main part of the territory.
