In the Owls also the femur is filled with marrow; but in the Diurnal Birds of prey, as in almost all other birds of flight, the femur is filled with air. In the Pelican and Gannet the air enters all the bones with the exception of the phalanges of the toes. In the Hornbill even these are permeated by air. "* My specimen of Cooper's Hawk is one of the largest, some 20 inches long. She is sometimes scarcely more than 18 inches long, while the male is never more than 1 8, and may not exceed 16 inc...hes in length. This species, which in structure and color is almost precisely like that of the Sharp-shinned Hawk, being, however, unmistakably larger, makes with it, and it only in this country, a strongly marked genus, the Accipiter the distinctive generic points being: 1st, that the feathers extend but slightly down the tarsus; 2d, that the toes are long and very slender, much webbed at the base, * Comparative Anatomy and Physiology of Vertebrates, by Richard Owen, Vol. 1, pp. 213, 214.
