Day. These seem to arrive & leave at about the same
time as the condors but a few may hang around
or even roost near the food after condors have departed.
9:12, I saw 2 condors circling about ½ mile S. of the
bait, upper one with feet down, & a 3rd, ¼ ± mile
further S. 6 condors & 3 buzzards in a loose group
circling ½ ± mile S. of our bait at 9:15, at 9:17 I saw
one adult drop down as if to land near the power
line & road about ½ ± mile S. of bait. By 9:21 at
least 3 condors had landed at that spot (about 100
yds. from power line towers it appeared). One turkey
vulture passed 100± over the bait, then headed S. 9:24,
I saw 5 condors & 6 ± turkey vultures flapping/flapping
away to W. of the landing spot over the flat ground.
One gave 2+ successive flaps, 9:27, I saw another
rise flapping from that spot. It flapped seldom when
at ± above height of power line towers, & rose
circling over the spot where it took off. A bunch of
condors & buzzards worked nearly over me, &?
at least (condors) were circling 300±' over my bait
at 9:30. The birds left within 2 or 3 minutes - per-
haps they didn't see it. Retrogressing: I watched one
bird circling to gain altitude yesterday, and it
kept the tail constantly tilted with low side away
from the turn. There were no straight stretches
in this circling - all curving flight. I watched
