Gymnogyps californianus March 9, 1946 Hopper Canyon, C.T. and rising. About 7 cardors were seen in vicinity of the pool atop Big Cave (dry?). We left & hiked up the trail at 7:45. At that time there were about 7 cardors in air milling above Big Cave. Later there were 9. Only about 3 at 5 p.m. These birds were probably disturbed by our presence the none of them soared close over us. The last arriving birds got to Big Cave about 4:30 p.m. -- a rather late arrival time & be- lieve possibly due to distant travel today or to light breezes in the afternoon. Sky clear but heavy haze to about 7500 ft. level. We went to Old Cabin to camp. Work told me that Dan Bleitz brought a man from Colliers magazine & a female model up to the Wolk cardor nest on the day the chick was found dead. Supposedly this was for the purpose of getting pictures & an article for Colliers. Work also said his group found 2 adults hanging around Arundell Cliffs quite consistently last year. He also said the road through the head of Hopper Canyon had been gone over, & repaired since his last visit here (Oct. '45). He said he had spent 5 days in the cave blinds trying to get pictures
