Beechey at Mazatlan, and the type is preserved in the British Museum. Nothing has 
been recorded about the habits of this species, but they are probably very similar to 
those of its northern ally Z. gambeli.

In the Barred Partridge the sexes are similar in plumage, and have a well-developed 
crest extending much beyond the feathers of the head. The tail is nearly three-fourths 
of the length of the wing, and composed of twelve feathers. The first primary-quill is 
intermediate in length between the ninth and tenth. 
Only one species is known.

Nothing is known concerning the habits of this bird, which appears to be confined 
to Mexico. The locality “ California,” given by Gould when describing the species, is 
no.doubt erroneous. Immature specimens are peculiar in differing from the adult in 
having the eyebrow-stripes and the greater part of the chin and throat black, and have 
been described in this phase of plumage under the name P. personatus.
