In buff birds, and in red birds in which it is desired to reduce the black as much as possible, slate in undercolor should be scrupulously avoided, and selection made for under- color as near the surface color as possible. The strongest buff and red undercolor is always a little lighter than the surface color, but strong surface color is often found with weak undercolor. In these colors, if surface and undercolor are very nearly the same shade and the former somewhat faded and mottled by exposure, a bird may appear to have good undercolor and poor surface, and in such cases the under- color may afford a better index of the breeding char- y\g. 56S.
