1915 BIRDS OF CALIFORNIA 69 
Status—Common in summer practically throughout the state; abundant in 
winter below the level of heavy snowfall. Breeds from the hottest parts of the 
Lower Sonoran zone (Colorado River near Yuma, ete.) up at least through the 
Canadian zone on the higher mountains, and from the dryest deserts to the north- 
ern humid coast belt. This hawk is thus one of the few birds of marked indif- 
ference to climatie conditions. There is possibly a distinguishable race in the 
extreme southeastern corner of the state, in the ‘‘sahuaro belt’’ (see Grinnell, 
Univ. Calif. Publ. Zool., xm, 1914, p. 126).
