In breeding, the smallest individuals which are suitable in other respects for breeders, should be selected in order to keep down the size and offset the tendency to breed larger in successive generations. In type the Calls are practically miniature Pekins except that they should have a very short, rather broad head and bill. The broad flat and short bill and the round short head give the head an appearance which is often described by the term "button headed". In this breed avoid birds which show arched backs. The body should have what is known as a flatiron shape, that is, should be broad at the shoulders and taper toward the tail. Too deep keels and narrow shoulders should be avoided as should also too long bills. Call ducks, together with East Indias and Mallards should have their wings clipped or be pinioned, that is, have the first joint of one wing cut off, to prevent them from flying away. _The Gray Call._ The plumage of the Gray Call is practically that of the Rouen although they are not quite as good in color as a breed. There is more of a tendency for some of the birds to run to dark and others, especially the males, to run too light in color. While they are likely to be well penciled the shade of color is apt to be wrong. White in the flights and under the wings must be guarded against as must also absence of ribbon or wing bar in females. The color of the plumage is likely to fade with age but after the birds moult and secure their new plumage, the color is usually higher again. In general the same color characteristics hold true as with the Rouen and the same defects must be guarded against. [Illustration: FIG. 8. Upper--Gray Call Drake. Lower--Gray Call Duck.

They breed very true in color and should be free from creaminess. The same general defects must be watched for and avoided as in the Pekin. [Illustration: FIG. 9. Upper--White Call Duck. Lower--White Call Drake. (_Photographs from the Bureau of Animal Industry, U. S. Department of Agriculture._)] _The Black East India._ This is a black breed which is small in size being a bantam duck like the Call. As a matter of fact it is a miniature Cayuga. The color should be black throughout and the same color characteristics hold true as in the case of the Cayuga. The same color defects must therefore be guarded against, the worst one being white in the breast of females especially. Avoid breeding from a drake with a black bill as in this respect the breed differs from the Cayuga since the bill of the duck should be black but that of the drake should be very dark green. Purple barring must be carefully selected against.
