Cayugas are splendid birds for a restricted range and breed well in confinement; they are quiet, docile, and form a strong attachment for their home, evincing no inclination or desire to stray far away from the place where they were bred. They are hardy and prolific, producing from 80 to 90 eggs in the spring, and sometimes they also lay again in the autumn. They are easily kept in good condition, but if fed too liberally they will fatten too quickly and will become too heavy behind. The ducklings are hardy and easy to raise, and attain good size and weight at an early age. The head of the Cayuga is small, with glossy black plumage; bill rather short and broad, of dark color, black being preferred; the eyes dark hazel. The neck is medium, gracefully curved, clad in black feathers with a greenish luster; the back is broad, and the body long, well rounded, and very plump, the feathers being of a glossy black hue. The wings are long and are carried smoothly against the body, and are black in color, excepting those of the duck, which are sometimes of a dark brown. The coverts of the drake are a very lustrous green black; the tail feathers are black, as are the thighs. Black shanks, toes, and webs are preferred, though dark slate color is permissible according to the standard requirements. The color of the plumage must be lustrous black throughout, and feathers of any other color will disqualify a bird in the showroom. =Weight.=--The standard weight of the adult drake is 8 pounds; adult duck, 7 pounds; young drake, 7 pounds, and young duck, 6 pounds. COLORED AND WHITE MUSCOVY DUCKS. =History.=--Muscovy ducks (fig. 6) form a distinct genus, having several peculiarities or characteristics which make them different from others. They are sometimes called the Musk duck, owing to the odor of musk which pervades the skin, but which is not noticeable when cooked. These ducks are found wild in the warmer regions of South America. In Brazil they are extensively domesticated and are prized very highly for eating. In this country and Europe, particularly in Germany, they are bred in large numbers. Wild Muscovies are easily frightened and very good flyers; they fly into trees when alarmed and remain there for long periods of time before leaving their place of concealment. They sometimes build their nests in branches of trees, and also in hollows near water.
