The Voice of the Bald Eagle has a weird, human quality. Dr. Fisher says: f'At a distance the note of the Bald Eagle is not alto- gether unpleasant. resembling somewhat that of Sea Gulls, but near by it is g ’ating and suggests a maniacal laugh.” Dr. William L. Ralph writes in Captain Bendire’s Lit'e Histories of North American Birds, p. 277: “The cry of the male is a loud and clear cuc-rar-cm‘, quite dif- ferent. from that of the female—so much so that I could always recog- nize the sex of the bird by it; the call of the latter is more harsh and often broken.”

The conspicuous white head and tail of adults of this species render it easy of identifi ~ation even at a (zonside ‘able distance. Young birds too closely resemble Golden Eagles to be distinguished with certainty, but the rarity of that species in the ‘ast makes it probable that any Eagle observed is a Bald Eagle.

“The food consists of water-fowl and other birds—largely of Vari- ous arctic species of Grouse which are *aptured on the wing. All these northern Falcons were formerly esteemed l'or hawking. as they still are by the Mongol races; their style of flight is magnificent—much swifter than that of the Peregrine-and both are deadly ‘footcrs’ (i. e., tenacious of grip), but they lack spirit and dash " (Saunders).
