Specimens of this Parrot vary a good deal as to the relative amount of the white 
and blue colouring of the top of the bead, the white in some specimens encroaching on 
the blue, and in others the opposite is the case. Most specimens, but not all, have a 
narrow frontal edge of red feathers. 
The range of C. albifrons is somewhat remarkable. In Mexico it is a bird of the 
west coast from Sonora to Tehuantepec. It is absent from the Eastern States, but in 
Yucatan it is abundant. In Guatemala, again, it appears as a western bird, with the 
exception of the flock or flocks which frequent the hot springs situated on the road to 
Vera Paz between the Rio Motagua and the village of Chuacus. Our skins from 
Nicaragua are from the central region and Chontales on the eastern side. In Costa 
Rica it appears to be a western bird.
