California Condor Eben Tschirnian 11 September 1964 Swainson's hawks, which he claims to have seen in large numbers sitting on the ground, for the first time, about 5 or 6 years ago, and that he admitted not knowing adult from Junvenile Condor until Jan acquainted him with the differences in these age groups last year; that the fact 20 plus Condor were counted first when he first saw the 60 plus Condor in November and that the remaining flock had to be made up of 40 plus Condor which with what experience a man had counting large flocks of wheeling and milling birds would be next to impossible especially if the two flocks were only one-quarter mile apart which distance could not well separate two large flocks of wheeling Condor creates a situation that prevents my accepting his observation of 60 plus Condor as correct. As Carl Koford stated when told of this observation "I wouldn't believe it if I had seen it myself!" Another sighting of Bertram Snedden Jr. where his sons Bertram Snedden III and Richard Snedden also were present and counted the birds was made in Santiago Canyon on when all three of the above observers agreed on the number of Condor that swung up out of the canyon as 33 Condor is acceptable on the grounds all three Observers agreed on this number and that this Count was made with members. The three observers scattered at separate locations within plain sight of this gathering of Condor. Shedden Condor sighting 888
