stratus at Rim level, fair SW breeze. There seemed to be a condor squated in #12 nest cave. Tbird's finally showing is sheltered from above by an overhanging rock which protrudes 4+ ft [illegible]cave. At 12:20 I saw two circling & rising over North Point. I timed 3 circles of one at 17, 18, & 19 seconds. At 500' alt. they flew glided toward Old Colin, just under & sometimes in base of cloud cloud.
At 12:35 I saw one adult perched atop Flat Ro. Occasional sunshine through cloud breaks. Turkey vultures soared with great steadiness near the foregoing circling condors.

One spiraled near North Creek falls, feet down, but then seemed flight near North Point with feet up. 1:20 one circling over Arundell Ridge & 1 adult perched there. 1:30, 3 soaring over Arundell Ridge.
One adult alighted atop a rock outcropping about [illegible]there

The displayer tracked away when approached &
