CONSPICUOUSLY BLACK AND WHITE 399 



may be studied in almost any locality from Pasadena to 

 San Diego and eastward. Stragglers have been ob- 

 served as far north as San Jos£, Chico, and Marysville, 

 but their usual haunts are the warmer regions of the 

 southeastern part of the State. Here they nest in the 

 oaks and mesquites, building a loose flat structure which

 cockatoo fashion, as he continues his adulation. In fact, 

 the only time I ever saw it lowered was when one of 

 these handsome birds seemed to be scolding a female, 

 whether his mate or not I do not know. He stood be-

 harsh notes and swaying from side to side in anger. As

One pair which nested in an oak tree near Pasadena 

 appeared suddenly in the neighborhood on the morning 

 of May 16, and a few days later were discovered at work 

 on a nest. A watch was kept from a distance with field
