228 USEFUL BIRDS. 
The following, from Mr. Kirkland’s notes, made at Mal- 
den in 1896, shows that this bird is of value in woodlands, for 
the observations were made in the woods : — 
A sawfly (probably Selandria) is at present one of the insects most 
commonly devoured by the Baltimore Oriole. These birds are very 
abundant around the experiment station, and I have repeatedly seen them 
feeding upon these sawflies, even as early as 4.30 one bright morning. 
By 6 or 7 o’clock these birds are well at work, feeding around the build- 
ing. Ihave seen them eat cankerworms, and, what was more interesting, 
devour a large Tortricid larva, which rolls the leaves of the white oak. 
This larva rolls the leaf around itself, thus forming a kind of cylinder, 
within which it feeds. ‘The Orioles put their bills into one end of the 
cylinder without tearing the leaf, and pull out the larva.
