Melanerpes formicivorus

8 May Power struggle here this morning! Jim watching.
I came down about 945 and saw 10+ birds = a good
amount of chasing. Jim reports no activity at nest 36
I checked it: 3 dead babies + 1 unhatched, fertile eggs that
had been pecked at & broken. The latter is the only potential
evidence for infanticide, I fear, as the kits were intact.
1130. Watching with net up. (1) ♀ M/or-DB #2502
3 ♂♂ in Tree#2! (2) Red/or #2507 (3) ♀ DB-or/or-DB #2502 (?)
♀DB-or/or-DB also (3) ♀ LB/LG #2505 - 3 sisters
from WGate here! #2471 here!
In main tree: ♀ DB-wm(N)/DB #2330.(Sch Hill). Presumably
some subset or all of the Schowl Hill helper ♀♀ (there are
7!) here winning. (2) ♂ or/M#2567 (SHill).
1210. Caught ♂ 2471 in net - bled w/in 5 min for
Plasma and released.
Jim's seen several more of the Sch Hill ♀♀. - 5 appear
to have been seen (99 2210, 2330, 2555, 2556, #2567).
1230. ♂ in Tree2: 3 Red DBs ?
♂DB/Wh-Red #2471.
38 are mostly with the SH ♂♂ in Tree#1, coming to
visit the WGate ♀♀ in Tree#2 occasionally. Still going
well at 1245.
1315. 8 birds get together in tree#1: looks like 5 ♂♂ & 3 ♀♀, most
likely the 5 Sch. Hill ♂♂
26 May
930 Watching. All quiet. There are still stores here.
(1) ♀ Bk/LP #2210 (from SchHill). (2) ♂ Red/DB #1901
(3) ? DB-WN(N)/DB #2330 (going into hole!) (4) ♂ DB/M #2473 (to ♂ 1901),
(5) ♀ LP/M #2556. At least 3 of the SHill ♀♀ still here!
