BIRDS, CATERPILLARS, AND PLAN! LICE. 135 
trees, and took two of the tent caterpillars from a low branch. She 
would hammer them on the ground for quite a time, then swallow them 
whole. When she had swallowed the second one she saw me, and flew 
away. 
May 19.—A pair of Redstarts were in the orchard most of the fore- 
noon, and were apparently eating cankerworms most of the time. ‘They 
would take those that were spinning down by threads. In the afternoon 
I saw one come to the 
apple tree and remain 
for about five min- 
utes, and take eleven 
brown-tail larve. A 
pair of Tanagers came 
to the apple tree and 
remained four min- 
utes, and one took nine 
and the other sixteen 
brown-tail larve. <A 
Black and White War- 
bler came to the apple 
tree and remained 
about ten minutes, 
and took twenty-eight 
brown-tail larvee, that 
I saw, from the leaves 
andtrunks. He prob- 
ably took many nore. Fig. 44.— Warblers feeding on young caterpillars of the 
gipsy moth. 
A pair of Yellow 
Warblers came to the tree, and each took a few, but they were so 
active I could keep them in sight but a moment at a time. 
May 20.—In the swamp off Broadway, Everett, the Warblers were 
very plentiful in the morning, and were present in quite large numbers 
until about 10 o’clock. Most of them were in the tops of the trees, and 
it was a difficult thing to see what they were eating. The Yellow War- 
blers, Yellow-throats, and Redstarts were feeding on the trunks of the 
trees. There are very few limbs on the trees for a distance of fifteen 
or twenty feet from the ground. The Warblers would cling to the 
bark and pick the gipsy moth larvee from the crevices of the bark. 
Their habits were different from those of a Creeper. Instead of cling- 
ing to the bark with the body lengthwise of the trunk, and supported 
by the tail, their bodies were crosswise of the trunk, and they depended 
wholly on their feet to hold and balance them. They were hopping 
round and round the trunks so that it was impossible to count the number 
of larvze eaten by any one Warbler, or to keep him in sight any length 
of time, on account of his swift movements. There were a great many 
Crow Blackbirds that were nesting in the evergreens in Woodlawn Cem-
