The Baltimore Oriole {Icterus galbula). 



Next to the cuckoos the oriole takes rank as a destroyer of caterpillars. 

 Stomach examination shows that thirty-four per cent of the food for the months

 insects. One stomach contained no less than ioo of these creatures. The oriole 

 is not a lover of the forest, but prefers the more open groves, or the borders of 

 the dense wood. The insects which it eats, however, are the same as those which 

 feed upon the leaves of forest trees, so that by destroying them the bird reduces 

 the sum total of the species, and so benefits the forest as much, if not so directly, 

 as it would if it ate them upon the forest trees. Several other species of orioles are 

 found within the borders of our country, and all of them show the same fondness 

 for caterpillars for food. 



The Robin {Morula migrator id). 



The common robin can scarcely be called a forest bird, though instances have 

 been known where it has nested in the depths of the woodland, and it was observed 

 by the writer in the backwoods of Maine, far from farms or any extensive cleared
