4A, FALCONID A. 
below the eye, nearly black; the back and upper surface 
bluish slate or ash colour, becoming lighter in colour at 
every succeeding moult, the males usually the most so: 
the feathers of the back, wing-coverts, and tail, barred with 
a darker tint; the primary wing-feathers brownish black, 
the inner webs barred and spotted with rufous white; the 
front of the neck white, with dark longitudinal lines; the 
breast rufous white, with dark brown transverse bars; the 
flanks, under tail-coverts, and the under surface of the tail- 
feathers, barred transversely with dark brown and greyish- 
white; legs and toes yellow, the claws black. The figure 
here given was taken from a very fine female of large size, 
in its second year, but still retaining one outer tail-feather 
of the first year on each side. The wing and tail-feathers 
are not changed in the falconide in their first autumn. 
Young Peregrines have the head and upper surface of 
the body and wing-coverts of a brownish ash-colour, the 
edge of each feather rufous; the dark longitudinal streaks 
on the white under side of the body more conspicuous, but 
gradually shortening and spreading laterally, ultimately 
change their direction, and become transverse. This change 
is first observed on the feathers of the belly and flanks. 
The vignette below represents the faleconer bearing his 
Hawks to the field.
