52 GAME BIRDS OF NORTH AMERICA. 



Partridge should inhabit the same district as the Scaled 

 Partridge, the two species associate together apparently 

 on most amicable terms, but the kind of ground each 

 prefers is usually of so different a character that they are 

 not often found together. The Blue Partridge is a hand- 

 some bird and attractive in spite of its unsportsmanlike 

 habits, the markings of its plumage causing it to appear 

 as if covered with imbricated scales, a rather unique dress 

 among its brethren.
