(11 February) 1115. Leaving. Nobody seems anxious to get where I could see them.
16 February Purge:
♂#196 (jun.) Last seen 2 Nov. 1975, gone by 9 December, Dis. about 21 Nov. 7-2 wks.
This bird does have a small probability of still existing, inasmuch
as he apparently had lost his wing-sheath. I suspect that
he's gone, however.
1 March 1645. Saw jLaRW#231, ♂rad/light#66 + 1-2 others all up in
the Valley Oak perch tree during a short pass.
8 March 1330. Came by to see what's up. Found ⚫♀CBLW#232 • up on the
knoll toward ARF, flycatching despite cool, cloudy conditions.
1430. 28° in another perch tree a little further away; one begged
from the ⚫ second and was apparently unbanded (@8349), the
adult couldn't be identified. Still nobody down at storage trees.
1440. ⚫♂Rw/1B-w#66 went to eat an acorn at the top of the
sycamore nest tree, then flew across the road to the area
where the other birds are.
1500. I went out and climbed up the hill; just as ☀️ I passed
the Valley Oak perch tree I heard a call and at least 5
birds appeared in another Valley Oak a little further up;
I saw ⚫♂La-Blk/1G-Blk#63 and possibly ♂yellow, 1 am (the
adult I haven't seen since December).
1525. All of a sudden birds began showing up at the Valley Oak perch
tree (now below me); possibly a bird (intruder) was chased. Seen
were ⚫, ⚫, and ⚫♂WRW#233, ⚫♀CBLW#231. Birds are definitely
spending much of their time up here in the gulch area down
as far as the perch tree, and up probably almost to ARF.
1540. Success! ⚫♂ye/1Bor1G-#87 came to the Valley Oak perch tree,
