This beautiful species was discovered in the course of the voyage of LA PEROUSE, and figured in the atlas accompanying the account of that unfortunate expedition, but without any other notice respecting its habits or distribution, than an intimation of its having been found abundant in the plains and thickets of California, where it formed large flocks. MR. TOWNSEND has lately sent me a beautiful specimen of the male, which he procured on the 6th of March, 1837, near Santa Barbara in California. I have to regret, however, that he has not furnished me with any account of its habits. MR. NUTTALL, in speaking to me of this bird, informed me that it is very gentle or confident, so as to be in a great measure regardless of the approach of man, that its manners resemble those of our Common or Virginian Partridge, and that the males in spring are seen perched on low bushes, where they utter their love-notes in the same emphatic manner as the species just mentioned.

Claws long, rather slender, arched, rather obtuse.
Plumage full, firm, blended. Feathers on the fore part of the head linear, recurved, stiff; those of the neck oblong, of the throat blended, of the other parts generally broadly ovate. On the top of the head is an elegant crest of elongated feathers, six in number, at first decurved, towards the end recurved, narrow at the base, broad towards the end, with the webs deflected, the longest an inch and two-twelfths. Wings short, convex, much rounded, the fourth and fifth quills longest, the first eight-twelfths of an inch shorter. Tail rather short, much rounded, of twelve feathers.

The back and wings are greyish-brown, the outer secondaries margined externally, the inner internally, with light red; the tail brownish-grey.
