obscure as to be passed over unnoticed by most birds. Ants are eaten 
mostly in spring, grasshoppers in July and August, and wasps and 
spiders with considerable regularity throughout the season. 
Vegetable matter amounts to only a little more than 16 per cent of 
the food during the bird’s stay in the United States, so that the possi- 
bility of the oriole doing much damage to crops is very limited. The bird 
has been accused of eating peas to a considerable extent, but remains 
of peas were found in only two stomacrs. One writer says that it 
damages grapes, but none were found. In fact, a few blackberries and

groves and windbreaks near farms instead of the natural “timber” 
which it formerly used. It breeds also in parks and near buildings, 
often in considerable colonies. Farther east, in New England, it is only 
locally abundant, though frequently seen in migration. After July it
