80 BIRDS OF CALIFORNIA AFFECTING FRUIT INDUSTRY. 
recorded it is evident that the birds must exert a powerful restrictive 
influence upon the increase of the codling moth, as well as other 
insects. 
SUMMARY. 
In a résumé of the food of the bush tit the most prominent points 
to be considered are the fact that four-fifths of its diet consists of 
insects and spiders, nearly all of which are harmful; that more than 
half of its animal food is limited to a single order of insects, Hemip- 
tera; that it eats the particular families of this order which contain 
the worst of insect pests; that the vegetable contingent of the food is 
made up almost entirely of substances of no economic value. It is 
doubtful if more efficient checks upon the increase of many species 
of forest and orchard insects can be found than the titmice and other 
closely related species. Bush tits, therefore, are a valuable asset to 
the State of California and should be protected and encouraged in 
every possible way. 
Following is a list of insects identified in the stomachs of bush tits:

Membracidie, Aphididae. 
Jasside. 
KINGLETS. 
Kinglets, like gnatcatchers and titmice, are small, active birds and 
spend most of their lives on trees. So nearly do the feeding habits of 
these diminutive arboreal species resemble each other that in winter 
it is not unusual to see companies of titimice, kinglets, creepers, and 
nuthatehes all together, engaged in the same unending search for
