31 March
1215. At CV#1: ♀ in hole; nest could be soon. Also there
were the feathers from a well-plucked Woodpecker on the
fallen limb directly below the tree. No hope of identification!
But it looked like a Cooper's Hawk killing perch. Hence, one
of the birds here has probably recently been nabbed.
1225. At CV#2: ♂MV LG
Or-w/n/da-la #959; a baby from last year.
in the granary.
7 April
♀941 from CV Grande seen intruding at Blountoo.
10 April
700. Power Struggle at CV#1! Going to Dark Hollow but I
will return here.
8943
815. Nets up (2) at CV#1. Caught 1 ♂; ♀943 from CV Grande.
850. Watching: ⚪♀LB/Or-LB #960 from CV#2 (Blountoo??)
976 from
Sch Hill
③♂Or/LG-w/n(n)
④? ♂ LB-BLk /M → both these are prob 976.
910. Caught 9990 being chased! ⚪♀ M/Red-w/n #819 formerly of
Cazcbo
Seems to be 10-12 birds here, mostly ♀♀.
920: LB-DG/LP = 9966 from Blomore.
930. Caught a third banded bird being chased: ⚪above #819.
940. 9960, 9990, and ub ♀ together - all 3 (from "Blountoo") are
here. Furthermore, if I had to guess, I'd say they were winning.
945. ⚪♂LB/LP #966 from Blomore
Most of the serious fighting seems to be between (among) ♀♀.
953. ♂Or/blk-or #967 have eating an acorn. Most of the activity
seems to be ♀ generated. There are several ub ♀♀ here.
1000. Finally got an ub♀, so I have to head home and get bands.
1045. Have 3 more, inc. 9990 again; also 9960, 2 ub ♀♀.
1110. Watching again. Things have calmed down, but there's
still a fair amount of chasing.
