California Condor Eben McMillan 13 September 1964 We continued Talking in moderate tones that the bird could have surely heard. We also moved about in the Jeep that made considerable noise when our feet scraped the tin floor of the body or our knees, or feet, banged against the tin side. The above sub-adult Condor was brownish of color and lacked the ashy Sheen of adult plumage on the back, especially on the upper parts of the wing secondaries and primaries. The head was a pinkish red with a dark band of furry fuzz across the forehead. The upper mandible did not appear to be as Ivory Colored as is the case with an adult and the head was not as broad as is that of the full adult. Also, the definite and clearly defined white line on the back of full adult Condor was missing on this bird and a mottled, ill defined line was evident — see below. [illegible] We left this bird perched on this limb at sunset — 200 plus Turkey Vultures roosting below bent pine in Canyon at dusk.
