238 HUMMINGBIRDS 



Distribution. — Central and southern California, chiefly west o£ the 

 mountains, southern Arizona, and Lower California. 



Nest. — Plant down covered with bits of green mosses and lichens, fas- 

 tened by web, sometimes lined with feathers or fur ; placed usually 8 to 15 

 feet from the ground, in trees or bushes often overhanging- water. Eggs : 

 2, white. 



Food. — Spiders, small insects, and nectar from flowers ; also sap exud- 

 ing from sapsucker punctures. 



" Like all the hummingbirds this species follows the flowers, and 

 its local presence or absence is governed by their abundance or 

 scarcity. Thus, in August and September hundreds of Anna hum- 

 mers are to be found over the stubble fields and sunflower patches^ 

 attracted by the flowers of the 'tar-weed.' Duilng the winter 

 months they are found in profusion about the blossoming eucalyptus 

 trees. In January and February when the weather is mild, they 

 appear high on the mountain sides among the flowering manzanitas ; 

 and in March and April in the blossoming orange groves in the 

 valley, and about the currant bushes on the hillsides." (Joseph 

 Grinnell.)
