Melanerpes formicivorus
Bianca
20 November
3 of the Bianca ♀♀ (213+215, both 2nd yr, and 303, 1st yr) identified as being pretty regular at LA2, where only the ♂ apparently remains. Birds are still flying between these 2 areas, however. See LA2 notes for more details.
8 December
1330. ♂140 plus a few others seen as I counted stores:
Old tree: 341
Blue Oaks: 137
Main tree: 1006
"New" area: 245
Knoll VO: 487
10 December Purge: ♀♀ 213 and 215. Both moved (to LA2) about 15 November. We'll have to wait and see about any others, particularly the 1st-yr ♀ (#303).
12 December
1235. ♂140 and 21 other in knoll Valley Oak.
17 December

1230. Leaving. The 2 ♂♂ (142+214) still around. Others scattered. Young ♀304 sparlos verswunden. Perhaps bringing the captive up here would be a good idea after all.
21 December
1515. Back with the captive up in the main granary.
3 birds flew over almost immediately - 2♂♂ who kept their
