Snow-vultures are numerous in Kan-su, and we often wondered how they could find sufficient food, especially as the Mongols, Tangutans, and Chinese often eat carrion themselves, and the vultures would have but a small share of the dead domestic cattle.

A flight of a few hundred miles is no exertion to this bird, which sails all day long beneath the clouds almost without flapping its wings.
Such is their rapacity that notwithstanding their habitual wanness they return to the carrion after they have been several times fired at. Their tenacity of life is almost incredible: my companion and I once fired a dozen charges of slugs at a number of them only fifty paces off, without killing one.
