Note 71 — Chapter VIII
Reading edition
Humboldt's statement that the condor flies higher than Chimborazo has been questioned; but we have seen numbers hovering at least a thousand feet above the summit of Pichincha. Baron Müller, in his ascent of Orizaba, saw two falcons flying at the height of full 18,000 feet; Dr. Hooker found crows and ravens on the Himalayas at 16,500 feet; and flocks of wild geese are said to fly over the peak of Kintschinghow, 22,756 feet.
