The hair of the common capucin is of a golden olive, with white fur
bordering the face.
These curious little creatures are noted for forming a friendship with
other animals when in captivity. Baron Humboldt mentions one which used
to mount on the back of a pig every morning, and continued sitting there
during the whole of the day; and even when the pig went out feeding on
the campos, it still kept its seat, riding back again in the evening to
its home. Others have been known to choose cats for their steeds, and
perseveringly to keep their hold in spite of their active movements--
seeming to enjoy them as much as the llanero does those of a colt he is
engaged in breaking-in.
