3/4 mi E, 1/2 mi N., McChesney mtn, 1900 ft, San Luis Obispo Co., Califf.
Sept. 8.
Dr. Miller, Dehnel, the two McMullans & I
started up early to top McChesney mtn. Went
through open grassy fields with oaks. Dr. Miller
shot a juncce. Saw Bell Sparrows in Adenostoma
on hillriders. At 8 AM. spotted 14 Calif Condors
roosted on burned coulter pine snags in Adenostoma
brush on canyon side 1/2 mile away across canyon
from us. They were dispersed over an area 1/2
mile long along canyon side, a mixture of mature
and immature birds. As they were perched we
could see only about 4 birds with the bright
orange head of the adult. After about 45 min.
a good breeze began to blow up the canyon.
the condors began to stir and stretch. A few
took off, one adult appearing to sail over
to another snag to scare some of the
immatures into taking flight. 12 birds took
off, gained almost 1000 ft in altitude
in less than 5 minutes, and sailed
off in a direct line foo toward the
canizo plain. One bird went off by himself
in a direct line east instead of north,
and one went slowly at low elevation
down Martinez canyon. As the 12 birds
flew over our heads only 2 had the
brown
struck wing patch of the immature.
Several others had patches smaller
