of its California cousin and store up much food that it never eats, 

 thus contributing to the welfare of pilferers of the food. 



Lepidoptera, that is, caterpillars, are apparently not a favorite 

 food of the redhead. A few were eaten in the months from April to 

 October, inclusive, but in May only do they reach 10 per cent of the 

 food. The average for the year is 1 .63 per cent. One harmful species, 

 the wheat-head army worm (Helio-phila albilinea), was identified in 

 one stomach, which contained about a dozen specimens. Dragon- 

 flies, spiders, and millepeds, bits of a crayfish, eggshells, and a few 

 bits of bone and hair of some small rodent, altogether make up the 

 remaining 1 per cent.
