California Condor Elkhorn Mill 2 Sept. 1964 At 6:15 A.M. Fifty Two Turkey Vultures flew from roosting place on north slope of Canyon 1/2 mile SW of Farnsworth Ranch Buildings. Crossed northward over our camp and lit in trees around knoll where a dead Bull lay 1/4 mile North of Farnsworth Barn, and about 3/4 mile North of our Camp. This was 35 minutes before sunrise. The morning was quite cool and damp, with little wind. At 7:35 A.M., 45 minutes after sunrise, the Condor left its roost perch, circled once, flew west along ridge then landed in a dead Pine 300 yards West of the Bear Pine. As this bird preened itself one could see the head was of a light Orange Color but some dark fuzz was evident on the forehead. There was also a [illegible] of some sort at the base of the upper mandible that stuck up about 1/2 inch at least. It could have been a tuft of feathers or a growth of some sort; thus it looked much like the top- KNOT of a turkey gobbler when not extended. Much white could be seen under this bird's wing as it would be raised in preening. From what I could see I close this bird as a sub-adult.
