140 USEFUL B1BD8. 



He then went to the apple tree and took a brown-tail moth larva, picked 

 it to pieces, and swallowed it. He then took another, and was proceed- 

 ing in the same way, when he was driven out by the English Sparrow, 

 and flew up over the ledge out of sight. A pair of Red-eyed Vireos were 

 in the oaks near the apple tree for a long time, foraging. They would 

 hold on to the petiole of the leaf, hang with their heads down, and take 

 insects from the under sides of the leaves. One of them went to the 

 apple tree, took a brown-tail larva from the leaves, beat it on the branch, 

 and swallowed it. His mate then flew across the street, and he followed . 

 A Yellow -throated Vireo went to a small oak tree and took three gipsy 

 moth larvte that were resting on a burlap band. She scarcely stopped 

 to shake them at all, but swallowed them at once. A pair of Chestnut- 

 sided Warblers were busy taking eankerworms to their young. They 

 averaged one each, every three minutes for nearly thirty minutes. In 

 the mean time they themselves ate quite a number. The young could 

 not have been more than a day old. A Yellow Warbler came to an oak 

 tree on the edge of the orchard and took two forest tent caterpillars, then 

 flew to the thick apple trees and fed on eankerworms. Four Waxwings 

 visited the orchard for a few minutes and ate a few eankerworms, but 

 they seemed to be picking into the blossoms of the young fruit more than 

 anything else. A Redstart took a forest tent caterpillar from- a branch, 

 hammered it, and ate it. He then flew out and caught a small moth, 

 then flew into the thick woods. A female Black and White Warbler 

 took a forest tent caterpillar from the trunk of an oak, flew with it to 

 the ground, hammered it until she broke it in pieces, and then swal- 

 lowed the pieces. 



June 1. — An English Sparrow came to the apple tree, took a brown- 

 tail moth larva, and, after hammering it for a moment, flew away with 

 it to her young. A Field Sparrow came to the open space around the 

 apple tree, foraged among the bushes for a few moments, 

 then perched in a small oak and sang. He then flew to the 

 apple tree, took a brown-tail larva, flew to the ground with it, 

 and ate it. He then flew to the open fields across Highland 

 Avenue. A pair of Orioles came to the tree, and the male 

 ate sixteen and the female twenty-five brown-tails. They 

 were in the tree seven minutes. A Yellow-billed Cuckoo came to the 

 tree and stayed about eighteen minutes, including a rest he took. He 

 ate thirty-four brown-tails, then rested seven minutes, and 

 ate twelve more. He would give them a couple of shakes, 

 and swallow them. The Robin coming in spied him, and 

 chased him out. A Rose-breasted Grosbeak visited a tree 

 for a moment and took at least five brown- tail larvas. 

 He probably took more, as he was not in sight all the time. A pair 

 of Chickadees also visited the tree ; they stayed about five minutes. 

 One ate nineteen brown-tail larvas, and the other ate eight that I saw ; 

 he probably ate many more, as I could not watch him all the time,
