Of the two stomachs not included in the foregoing discussion, the one
taken in Florida in January contained 93 per cent of wild fruit and 7
per cent of weevils, wasps, and spiders; the one collected in Alabama
in February was entirely filled with animal food, of which 88 per cent
was caterpillars, 5 per cent May beetles, 6 per cent bugs, and 1 per
cent spiders.
_Summary._--The animal food of the wood thrush includes remarkably few
useful insects and contains some very harmful ones, as the Colorado
potato beetle and many of the Scarabæidæ, the larval forms of which
are the well-known white grubs which are a pest to agriculture in
preying upon roots of plants. The vegetable portion of the food
contains a small quantity of cultivated fruit, but observation shows
that the thrush is in the habit of picking up fallen fruit instead of
taking it fresh from the tree. The eating of wild fruit has no
economic interest except that it serves to distribute the seeds of
many shrubs and trees. There is no occasion to discriminate against
this bird in any way. It should be rigidly protected.
