Gymnogyps californianus June 6, 1946 Nr. Whiteacre Pk, Calif. flet down, soaring very close to some cliffs, 4 at 10:41 landed on a slightly whitened point of a sandstone cliff about 3/8 mile N. of and 400' below me. This was near top of the lowest of the big ledges below the first W.-running spur S. of Whiteacre Pk. The point was about 10' from top of the 80'+ ledge, & the ground below the cliff sloped steeply away for 1/4 mile to canyon bottom. 2 other points nearby were slightly whitened also. at 10:58 this bird flopped & jumped up- ward and broke into a 'V' in the cliff, out of my sight.

At 11:09 the other adult soared past the nest, crop area bulg- ing greatly. This bird continued 1/2± mile S. of nest, then Suffy Cheeks took off. They circled together, feet down, until at bird level above nest. Then both went into a steep banked dive for 150'+ ft. as a raven attacked them (a raven nest in a near cliff there). The raven attacked several more times, flying after the carders & croaking. Appar- ently it never actually hit a carder.
