Some Buzzards were fighting among themselves over small bits of carrion. The Condor would bluff these Buzzards away, then search about on the ground what they were fighting over. I never saw the Condor pick anything sizable although it would pick at the ground where Buzzards had been competing among themselves. At no time did the Condor go to the Jackrabbit bodies that lay on the ground within ten feet of it most of the time it was among the Buzzards. Now if it or any of the Buzzards touch the lamb carcass although a Raven occasion, a Pine Tar Preparation which is put on the lambs, when the tails are docked, or the young bucks are castrated, leaves a sticky, smelly, substance about where it's applied. This may be the reason this lamb carcass was not Eaten On. At 3:50 p.m. Something frightened the Buzzards that all took to the wing, some alighting 50 feet away, others circled the area several minutes before returning to feed. When Buzzards took flight the Condor hopped about flapping its wings as though confused, then ran up the hill 30 feet and looked about as the Buzzards returned. The Condor remained on the hillside, above where the Buzzards were again feeding, seeming nervous and suspicious. At 3:55 p.m. it partially opened its wings, lowered its head close to the ground, then hopped twice and was airborne.

Here this Condor seemed to hit air currents that during three turning circles raised the bird
