Melanerpes formicivorus
MacRoberts
Hastings Reservation
(5 August)
1205. 8ub in storage tree; 3rd #162 below him (ws gone). 8ub
landed and greeted 8ub.
1215. leaving. Looks like either the adult 8 has been replaced or
that I've been too hasty in deleting him; unfortunately in
lack of more convincing evidence otherwise I suspect I'll be
stuck taking the conservative route and assuming the latter.
1 September
1110. No stores remain, but there were 2 nice (big green acorns
in the tree recently stored, but already eaten as well. No birds
seen.
11 September
1400. Within a minute of my arrival 4 (!) birds were all
peacefully coexistent in the storage tree, 288 and 299.
1412. 299, both ub as far as I can tell, in storage tree now. One
just chased off an intruder who landed in the tree briefly.
1418. 8ub here now preening.
1450. Both 88 atop granary; 8 just landed with green acorn. Have seen
only 18 consistently since 1400.
1570. A 3rd 88 was just displaced by one of the 2 already there.
ADD: 8458. First seen as adult at MacRoberts 11 September. 8162
not seen, but "presumably" is the 2nd 8 here at 1400.
1515. [illegible]. The ub 8 landed in the granary and between
several hawkling flights displaced/chased both the 88 here!
He did this again after a few minutes. By 1520, he alone was in the
granary, while the 88 were still nearby but no longer in the same tree.
1525. One of the 88 returned soon after the 8 left.
1530. Leaving.
12 September
1015. In hide watching with net up.
1022. 8ub landed in granary.
