Last seen 18 Aug, gone 7 Oct
29April Walking by 1245, I flush a bird out of the 'usual'
nasty hole in the Valley Oak next to the granary,
Guess they may have a nest
16 May Philip reports considerable interest in the "Poison Oak" Hole
(81 + 82 second nests), but no sign of 9427, and only 7741
going into the hole. Very strange. Also, very quick visits by
all birds, so I'm not sure if they have a nest (Philip
saw no food in bills).
23may Big doings here: Watching from blind, 1400, I learn
① At least 2 new ♀♀ here: 9680 m / Blue and
♀505 (!) wnt/CPink from A1! 9505 is especially
neat, because she is a widowed ♀ (from death of ♂100, see
Susane notes) and apparently decided to leave A1, presumably
because all the ♂ helpers there have prevented replacement
♀505 is being tightly guarded by at least 3 ♂ (I think
♂102, ♂426, ♂691 (!)) and ♀680 appears to be being
guarded by ♂321 (again, not positive). Both ♀♀, but
♀680 in particular* are checking out the PO Hole. ♂497
also seems to be involved in guarding but I'm not
sure how at the moment. Clearly, BO needs no work
