California Condor Eden McMillan 8 November 1963 IAn and I left for Berkeley and M.V.Z. at 5:00 A.M. with the Two Condor Carcasses, Specimens No. 4 and 11 in the back of my pickup, arriving at the University of California Museum of Vertebrate Zoology at 9:30 A.M. We went to the office of Dr. Alden H. Miller who after discussing the general progress of the Condor Survey with us, then advised that we bring the Condor carcasses into the museum and turn them over to Ward Russell who will undertake to investigate the remains for any clue as to why they died. This we did. We lunchied with Starker Leopold who later helped us locate the Notes taken by Carl B. Koford during his study of Condor in the late 1940's, and later. We worked with these Notes until 3:30 p.m. When we then looked over five Condor Study Skins that are in the Collection of M.V.Z. trying to work out some clue that we could use in order that we can positively identify some age group of condor especially among large blocks. We thought that the dark color of the mandibles, especially the lower one would be a good clue to follow up in the hopes it would identify birds less than a year out of the Nest. We will have to do more skin comparison in order to follow this lead on to see if it holds up in all Study skins. The length of the Center Toe is less in Young birds as we learned from the M.V.Z. Skins. In doing more walking and climbing a young bird before it leaves the Nest wears the Toes down quite blunt especially the center one. This Center Toe, [illegible] or Talon, becomes long and sharp in the adult birds. Also the Neck feathers on young birds that have just left the Nest are more soft and fluffy than is the case in the-
