There, however, it can remain for hours or even days without once alighting. The Frigate r>ird, or ]\ran-o'-War Bird, has a l)ody scarcely larger than that of a chicken, but its tail is one foot and a half in lentj-th, and its wini^s measure seven to. FriLTute Bird. (Expanse of wings, 7 to 8 feet.) eight feet in extent. Having this enormous spread of sail, its flight is more easy and graceful than that of any living bird. I have seen hundreds of these birds floating in the air, facing the wind, without apparent change of position or the movement of a pinion, for long intervals of time. From this extreme development of the wing as a flight-organ, let us turn to those birds wdio have not the power of flight. The Ostrich, Rhea, Enni, and Cassowary are familar re])rcsentatives of this group. It is generally believed that these birds have lost the power.
