“[The] characteristic “owl-face” is due, firstly, to
the forward direction of the eyes; and, secondly, to a circular disc of
radiating feathers, more or less distinctly developed round each eye, and which
may be bounded by a ruff of closely-set feathers. In common with many diurnal
birds of prey, the owls have a short, stout beak, of which the upper ridge is
strongly curved, and the tip deflected in a perpendicular direction ; at its
base is a cere, usually covered with stiff bristles concealing the nostrils.
The feet are furnished with strong, curved, and sharp claws, and have the
fourth toe reversible.”
