Soaring of Hawk

Abstract

THE rest-house in which I now am stands close to the edge of a precipitous descent. There is a covered verandah in front, and we are nearly 9000 feet above the sea. I have just seen a hawk, or vulture hawk, circle round three times over the precipice. The whole time its wings were motionless (to the sight). Its first circle was on a level with me, the second was higher, the third was unquestionably higher still. As I sat I could see both the complete first and second circles. To see the last I should have had to go to the edge of the verandah. This appears to be a clear case of rising circles without (apparent) motion of the wings. I have seen the same thing from the plains, but have not been so sure of the fact observed. There is a light wind blowing, scarcely moving the trees.
