PEREGRINE. rea 
head, yellowish white, or pale rufous; neck behind, yellowish 
white with dusky spots; chin, yellowish white; throat, white; 
the band on the side of it blackish brown; breast, reddish 
white, or pale reddish orange, darkest in the middle, with 
longitudinal markings of a dark brown colour, and the centre 
of each feather the same; back, brownish black shaded with 
grey, the feathers edged with pale brown or rufous. The 
quill feathers of the wings are blackish brown, spotted with 
brownish white on the inner webs, and tipped with the same; 
tail, blackish brown, barred and tipped with brownish red, or 
reddish white, greyish towards the base; legs and toes, greyish 
or greenish yellow: as the bird advances towards maturity, a 
bluish shade becomes observable on all the upper parts, while 
the lower parts become more white, and the dark markings 
smaller, as well as more inclined transversely than longi- 
tudinally. 
Sir William Jardine describes a variety in a state of change, 
as having the upper parts of a tint intermediate between 
yellowish brown and clove brown. The tail, instead of being 
barred, has an irregular spot on each web of ochraceous, where 
the pale bands should be, and the longitudinal streakings of 
the lower parts wood brown, instead of the deep ruddy umber 
brown seen generally in the young.
