_Vegetable food._--More than nine-tenths of the vegetable food of the
wood thrush can be included in a single item--fruit. Cultivated fruit,
or what was thought to be such, was found in stomachs taken from June
to September, inclusive. It was eaten regularly and moderately, and
the total for the season was 3.74 per cent of the whole food. Wild
fruits or berries of 22 species were found in 72 stomachs, distributed
through every month of the bird's stay at the north. Beginning with
1.18 per cent in April, the quantity gradually increases to 87.17 per
cent in October, when it makes more than five-sixths of the whole
food. The average for the season is 33.51 per cent. In this
investigation _Rubus_ seeds (blackberries or raspberries) are always
reckoned as cultivated fruit, though probably most often wild. Besides
fruit, a few seeds and rose haws were found, which with a little
rubbish complete the vegetable food (40.41 per cent).
Following is a list of fruits, seeds, etc., identified and the number
of stomachs in which found:
