California Condor Ebon Mcmillan 15 January 1964 Tempests. In fact the Condor seemed to search out the most turbulent areas and so there to spend sometime just sitting on these winds and apparently handling them with ease and dexterity. From what I have seen of Condor in flight, during the last two days, I would say Calm air, and not strong, turbulent winds, are more of a problem to Condor to cope with. Of course boosting could be another matter and perhaps this is one reason the Condor return to the Hole-in-the-Wall to roost in winter and spring seasons, when heavy, stormy winds prevail. Perhaps the great cave, or cirque, that forms the Hole-in-the-Wall, modifies these strong winds to a point whereby Condor can come in to roost, in late evenings, without any trouble. As was our observations in past trips, to this area of the Percy Ranch, and Hopper Mountain, we have noted that Condor do not use the Hole-in-the-Wall in late spring and summer and, well into the fall months. Evidence is now beginning to build up that the Hopper Canyon, and its Hole-in-the- Wall roost area, are very critical to the welfare of Condor in winter and early spring seasons. It could be that without the Sespe Wildlife Refuge, a fall back on at this time of the year, Condor could have long since become extinct. At 9:07 A.M. as I was climbing up the east face of Hopper Mountain from our Camp and having already gained about one-half the distance, to the top, I saw a Condor (adult) coming around the ridge to the south flying close in towards the mountainside and about 200 feet below me. As this Condor crossed a fairly deep ravine
