Range Description

Carpodacus cassinii is found throughout the conifer belts of North America's western interior mountains, from southern British Columbia and southern Alberta in Canada, south through the Rocky Mountains of the USA to wintering populations in northern Mexico (Clement et al. 1993, Hahn 1996). Migration is erratic, dependent on food supply in the breeding range (Clement et al. 1993, Hahn 1996). Population trends should therefore probably be viewed with some caution, due to apparent lack of site fidelity (Hahn 1996), but the species has declined by 2.3% annually from 1966 to 2002 (J. Wells and K. Rosenberg in litt. 2003).
