Archibates lagopus 238 1875. (Nov. 22) which it invariably returned, the appearance of three birds hanging suspended in the air at the height of about 50 ft., all within a radius of 100 yds., and for many minutes without a single movement was very very interesting. Sometimes when the wind came in gusts they seemed to have some difficulty in preserving their equilibrium and flapped their wings rapidly at frequent intervals, but in every event their exact place was maintained to an inch. This descent on this prey was made (as described on p. 132 journal of 1873) in cycloid curves. At times all three would rise to an immense height in the air and sail in company. This sailing was performed with extraordinary ease and grace and the appearance of the bird and the position of the wings was very much like that of Cathartes aura. Heard no cry or note of any bird. They frequently lit on the ground usually on the top of some elevated knoll. Walked out to the sand hills behind Woodbury's when I shot a Finch & Flc, miculi; saw only one or two others of that species and perhaps as many E. corvata. When the small birds came I cannot imagine, as we looked everywhere for them. Saw a few Merques serrator & great numbers of gulls including Larus L. marinus, reached from by 81/2 M.
