The first distinctive characteristic among birds is that which
bears reference more especially to their feet: they have either
hooked talons, or else toes, or else, again, they belong to the
web-footed class, geese for instance, and most of the aquatic
birds. Those which have hooked talons feed, for the most
part, upon nothing but flesh.
