140 USEFUL BIRDS. 



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

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

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

 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 Iheni 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 larv;e that were I'esting 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 cankerworms to their j^oung. They 

 averaged one each, every three minutes for nearlj- thirty minutes. In 

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

 not have been more than a day old. A Yellow A^^arbler 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 cankerworms. Four Waxwings 

 visited the orchard for a few minutes and ate a few cankerworms, 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 tliick 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 awa}' with 

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

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

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

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

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

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

 ate sixteen and the female twent3-five brown-tails. They 

 were in the tree seven minutes. A Yellow-billed ("uckoo 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 brow^n-tail larvic. 

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

 of Chickadees also visited the tree ; they sta^'ed about five minutes. 

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

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