Feb 26 U.C. Botanical Gardens, Bordley, Plamda Co.,
California
Hiked up at 10:30 am. Clear, fairly
warm, slight wind. 4 of Red-tailed Hawks
seen were carrying on some sort
of display (mating?). One of the two in each pair
of them both flying behind
the other with legs & feet held
straight down stiffly and occasionally
swooping down on the other. At Gardens
birds were still thick around the
Chicken manure piles but noticeably
lacking were White-crowned Sparrows
- none seen or heard. Saw what looked
like a 1mm. Purple Finch (either
caulif. or Carins, I don't know which)
feeding on large berries on ground.
Fairly olive-brown above (not just
brown) especially on rump. Very quiet
singing bird. No calls or song. Stowwe
Jays seemed very much in evidence
as were Spotted Townees & Brown
Townees were hard to find.
Heard a song I didn't know from
Bachris thicket in NE part of
gardens. "see chirrrrrr" (-~--)
Repeated several times maybe 20 or
30 seconds apart. Clear first note
& chirr on about same pitch.
Ran down the Hutton Virgos call
"Zu-weep" (it sometimes runs together
as Zweeps). Also got good looks at
the bird near the Country Husbandry
building. I think I've camera some
Hutton's Virgos Ruby-cre's Hummers before
but think I've got them straight now.
At 11:15 am heard Stowee (?) Jays 'shy'm'
