OTHER WOODPECKERS, 33 
In addition to the 7 species of woodpeckers whose food has been 
already discussed, 57 stomachs have been examined, belonging to 12 
species and subspecies, mostly from the southern and western parts of 
the United States and British Columbia, as follows:

With such a small number of stomachs it is hardly worth while to dis- 
cuss the food of each species. The Three-toed Woodpeckers (Picoides), 
however, deserve passing notice, since their food contains a larger per- 
centage of wood-boring larve than any other woodpecker examined. 
As the food of the two species is practically the same they may be con- 
sidered together. The contents ofthe 10 stomachs consists of: animal 
matter, 83 percent; vegetable matter, 17 percent. It is a question 
whether this should not all be considered as animal, for the vegetable 
portion consisted almost entirely of rotten wood and similar rubbish, 
probably taken accidentally, and is not in any proper sense food, the 
exception being in one case where a little cambium had been eaten by 
one individual of the Arctic Three-toed Woodpecker (Picoides arcticus) 
aud a few skins of some small fruit by one Alpine Three-toed Wood- 
pecker (P. americanus dorsalis). The animal food consisted of 63 per 
cent of weod-boring Coleopterous larve (beetles), 11 percent of Lepi- 
dopterous larve (caterpillars), probably also wood-borers, and 9 per 
cent of adult beetles, ants, and other Hymenopterous insects.
