the vignettes make no distinction but that of colour, which is
indicative of age rather than of kind. The typical Egyptian Hawk may be
identified with the Falco Lanarius, or with the Peregrinus, but
naturalists tell us that “the Lanier of Buffon is the perfect state of
the male Peregrinus,” and that “the Lanner of Pennant is a young female
Peregrine.”
