California Condor Eban McMillan 15 may 1964 Sky was clear except for a few patches of high-thin cirrus clouds, it was moderately warm and a gentle west wind was blowing at 11:13 A.m. today as I looked from the front window of my house and saw two rather large bird shadows passing north of my house in a Northerly direction. Going to the large glass window I saw two adult Condor, moderately high, meandering Northward in an uneven sailing flight, as if hunting for food. The two Condor Continued on Northward for about three-quarters of a mile distance where they commenced to circle and gain altitude and were soon quite high. From this height these two Condor went into a flat glide after dipping the wings, and at 11:17 were lost from sight heading North by Northerly Northwest or in a bee line for the Cholame Flats. Today, while watching these Two Condor at a distance, there seems to be Two Charistics that one Can use to positively identify these birds when they are a Good distance away. These two factors would be predicated on Condor being observed to be either Circling or Coming, or going directly To or from the Observer. When Condor are circling the wrist motion of these birds is much more accentuated than is the case in Other large birds. Golden Eagle would more closely resemble a Condor in flight than any other Western American
