84 BIRDS OF CALIFORNIA AFFECTING FRUIT INDUSTRY. 
food consists so largely of insects and as these include so small a per- 
centage of useful kinds, the kinglet must be classed as one of the 
most beneficial of birds. To the horticulturist it is especially valu- 
able, as nearly all of its food is obtained from trees. With respect to 
the persistency with which it forages among trees, it differs conspicu- 
ously from such aboreal species as leave the trees in midsummer to 
feed upon grasshoppers. 
WESTERN GOLDEN-CROWN IKINGLET. 
(Regulis satrapm olivacens, ) 
Another kinglet, the western golden-crown, occurs sparingly in 
winter in some parts of California. Only 9 stomachs have been 
examined, but these in the nature of their contents are so similar to 
those of the ruby-crown that statements applicable to the latter are 
almost certain to apply as well to this species. No vegetable matter 
was found in any of the 9 stomachs, and the insects belong to the 
same orders and were taken in essentially the same proportions as by 
the other species. 
Following is a list of beetles which were identified in the stomachs 
of the two kinglets: 
Coccinella t. californica, Aphodius rugifrous, 
Adalia frigid. Diachis auratus. 
Newminus pallens, Crepidodera helLrines. 
NCYMIHUS HODUTOSUS, Hpitriv parvula, 
Hesperobarus abbreviatus. Notorus alameda, 
Corticaria ferrugiied, Aathicus vitidulus, 
Throscus sericcus, Lpion vespertinun, 
Listrus interruptus, Pityophthorus pubipennis, 
Beetles were identified as belonging to the following families: 
Staphylinidie, Scarabiwidiv. 
Coccinellidie. Chrysomelidie. 
Monotomide. Tenebrionidee, 
Lathridiidie. Anthicidie. 
Hlateridiv. Curculionids, 
Throscide. Scolytidie. 
Lampyridie. Other Rhynchophora. 
Milachiidee. 
GNATCATCHERS. 
(Polioptila spp.) 
Gnateatchers are small, active birds of modest colors and unob- 
trusive notes. While not conspicuous, they are none the less deserv- 
ing of respect and consideration. No complaints have been made 
that these busy creatures ever injure fruit or other crops. Their food
