792 REPORT OF STATE GEOLOGIST. 



California, however, most of the nests are placed in trees. The nest 

 is large. Two or three eggs are a set, and but one brood is raised in a 

 year. They begin nesting, in this latitude, in March, and continue 

 through May, and even far north fresh eggs have been found in June. 

 Several days, sometimes a week, intervenes between laying the eggs. 

 Incubation lasts about four weeks. It is performed almost entirely 

 by the female, who is supplied with food by the male.
