296 BLACKBIRDS, ORIOLES, ETC. 



most skillfully wrought nests a bird ever made, a perfect basket, 

 hung by the handle to the drooping bayonets in such a way that the 

 sharp points protected it and yet left the bird an easy entrance. The 

 nest was made of yucca liber, decorative touches being given by bits 

 of gray moss stuck on here and there.

In southern California the Arizona form of <"<-nUn1x has an ag- 

 gravating way of spending his time hunting about in the chaparral, 

 coming into sight only as he makes short sallies into the air or dashes 

 past you from one section of brush to another. 



He sings when out of sight, but the song is delivered with such 

 fervor that you can follow him by it when he is invisible. It is a 

 typical oriole song, a clear whistle with a rhythmic rise and fall, 

 and a chatter interposed between the high and low notes that sounds 

 as if he were taking breath. His mate is a quasi-musician, giving 

 his chatter and the first strain of his song. 



In southern Ari/ona, where mlxnnl is most abundant. Major Ben- 

 dire says that its favorite haunts are dense, shady groves of cotton- 

 woods and mesqnites in the creek bottoms.
