Melanerpes formicivorus
Upper Arnold 2
(26 January) A3 birds, but none seem to have cleanly separated as yet (even though I still expect that one of them, possibly #121, will do so eventually). Certainly she is the only bird that one can count on finding here.
27 January 815. Just walked by - a ♀ was in the storage tree sitting (presumably ♀#128), while a ♂ I'm, apparently ♂121, was sitting quietly in the Valley Oak nest tree. This resighting here under these conditions is enough to make me strongly suspect that he ( [illegible] ) (♂121) has indeed moved over for good at last. [see A3 notes for 27 Jan - he was seen there!]
3 February Purge:
♀230 (LBLW) last seen 19 August, gone by ~23 Sept; → Disappeared about 6 Sept. ±2 weeks
4 February 1300. No birds seen in passage.
1405. ♀, not doubt #128, in the Valley Oak nest tree when I came by again. Another bird seen. Possibly a 2nd bird flushed a minute later.
17 February One bird came by but wasn't identified. The count is 778, all in the main tree except for 1 acorn.
21 March 1550. Walked by, finding ♀128 sitting quietly alone in the top of the storage tree. Eventually she flew off towards the gulch, proceeded apparently by a ♂ from the nest hole area (?) who flew over to the other side (unless he was chased by her!). A few minutes later I watched an unbanded ♀ for a couple minutes sitting atop the tree by Arnold field toward A3; she eventually flew into the territory and was immediately met and chased by ♀128.
22 March The count is 521. I didn't see any birds in the area today.
