(18 Mar) I haven't noticed any Flycatching (Hastings style). It's
always cold, cloudy, or windy - day length is the same.
I can't imagine a big pulse of insects here - what
is growth rate like? Just saw a bird that looked like
a scarlet tanager - striking! 3 black wings w 2 fat white bars
7 similar, but body is yellow
1034 7 arrived at an already opened acorn and began eating
(again, little bites) She continued working on this acorn until 1043, when she Flew away suddenly.
No dark eyed individuals seen yet. Alarm called for
passing small buteo (broad winged hawk?)
There seems to be at least a couple ACWs around the
curve oak at all times. I would investigate other
oaks for acorns, but that would mean climbing fence or
trespassing in this rather populated area. Higher up
the volcano there are fewer people, but there's no way
to get there from here. Though it's 50° or windy, there
are cattle egret here. At 1059 a 7 landed on the same
acorn as 1034 7 and began eating. Her eating rate slowed
until she was just sitting on it looking around. She left at 1105
1115 Watching ravine "nest" Free. Bird sitting
near hole, but did not visit. I think I see a stowed
acorn (!) in a semi-natural hole near the top of the
ravine tree \acorn Watched ravine bird forage
in grass for 1.5 min Others ground foraging too - should
do some sweep netting. 1142 rain - quit
1330 watched Watched ravine "nest" for @ 15 min -
no interest. There are at least 3 birds here,
