Tetraogallus himalayensis -- Himalayan Snowcock. Alternate name on piece: Tetragallus himalayensis [Himalayan snow-partridge]. The published plate is completely different in composition and poses, and eliminates a third bird. Artist's name(s): Wolf, Joseph; Gould, John. Text says "taken from a drawing by Mr. Wolf," but this seems clearly to be Gould's work, with color added.
