BIRDS, CATERPILLARS, AND PLANT LICE. 127 
twice and ate plant lice and some small larve. Three Red-eyed Vireos 
came to the oak trees and ate the larvae from the leaves and the plant 
lice from the birch leaves. 
June 38, 1898. —I went to the park near the boulevard. Saw an 
Oriole take four forest tent caterpillars, one at a time, and carry them 
away to its young. A Yellow Warbler was eating plant lice for fifteen 
minutes, although it rained quite hard. <A pair of Oven-birds were 
feeding on plant lice fora long time. Several Chestnut-sided Warblers 
came to the birch trees and ate plant lice, then went to the oaks and 
poplars and took larvee of different kinds and ate them. A Catbird was 
picking larvee from the under sides of the leaves; most of them were 
green larvee. Two Chewinks (Towhees) were scratching in the leaves, 
but I could not see what they got from the ground. They took some 
forest tent caterpillars from the trunks of the oaks. A Maryland Yel- 
low-throat came out of the thick brush and ate plant lice for about ten 
minutes. A Rose-breasted Grosbeak was busy in the oak trees. He 
came to the birches for a moment and ate plant lice. A Red-eyed 
Vireo ate two forest: tent caterpillars, taking them from the under side 
of alimb. The Indigo Bird could not be easily observed; he was evi- 
dently eating plant lice. The Brown Thrush could not be seen dis- 
tinctly ; he was searching in the fallen leaves. A Black-billed Cuckoo 
had a nest near, and carried forest tent caterpillars to its mate. 
JUNE 6, 1898.— The Red-eyed Vireos seem to be feeding on more 
gipsy larve than the other birds that come near enough to be observed. 
They will take a larva from the under side of a leaf or a crevice in 
the bark, and, putting one foot on the larva, will proceed to pull it to 
pieces, eating the softer parts and dropping the hairy parts. An Oven- 
bird came to the colony and ate four of ‘the small larve, picking them 
from the under sides of the leaves. I saw a Black and White Warbler 
carrying cankerworms to its young; it would take two and sometimes 
three at atime. A Baltimore Oriole was taking tent caterpillars to its 
young, taking those that were on the outside of the nest. A male Bobo- 
link came to the birch trees and remained about twenty minutes, picking 
plant lice. ‘The Field Sparrows and Indigo Birds were also busy feed- 
ing on plant lice. A Wood Thrush took the cankerworms away to its 
young. A Chewink took two tent caterpillars from a bush and ate them. 
A Scarlet Tanager flew from the oaks into the apple tree and ate canker- 
worms. The Chestnut-sided Warblers were the most plentiful of any 
of the birds, and were eating plant lice almost constantly. i 
JUNE 8, 1898. —I went to the park, Stoneham, near Spot Pond, to 
observe the feeding habits of birds. A pair of Brown Thrushes were 
feeding their young ; they averaged going to the nest one every five 
minutes, and carried several larvee each time. A Kingbird caught a 
Buprestid beetle and ate it. I had made an attempt at catching it when 
it was on the trunk of the apple tree; it flew, and was snapped up by 
the Kingbird. This orchard is infested with cankerworms. It is situ-
