BIRDS, CATERPILLARS, AND PLANT LICE. 145 



billed Cuckoos that were coming and going all the time I was there, 

 and they were eating large quantities of larvae. The young would take 

 a larva and work it over with the bill for a long time, and then swallow 

 it. The old ones would take a larva, beat it on a limb a few times, and 

 swallow it. Most of the birds were gone by 8.30 A.M. They were 

 most plentiful between 5.30 and 7 A.M. The Cuckoos and Chickadees 

 were coming and going all day. 1 When we came in sight of the place 

 after dinner we saw nine Crows fly to the edge of the stripped patch, 

 and alight in the trees that were partially stripped, but when we tried 

 to get near them, they flew away. When I went into the colony I 

 found there were still two Crows there. I saw one of them eat three 

 pupae, then they took flight. Several species that were not seen to eat 

 the moth were heard in the woods outside the stripped area. Among 

 the number were the Red-eyed Vireo, Indigo Bird, Wood Thrush, Che- 

 wink, Maryland Yellow -throat, Black- throated Green Warbler, Chest- 

 nut-sided and Yellow Warblers. 



JULY 12. In the morning, when I came in sight of the place, I 

 found the whole flock of Crows there, and could hear them feeding 

 their young very frequently. When I tried to get near enough to see 

 what they were doing, they all flew away. The Grosbeaks were back 

 again to-day. They kept on the farther side of the tract, and were eat- 

 ing both pupae and larvae when they could be observed. The Black- 

 billed Cuckoos were eating great numbers of the larvas, as was the case 

 yesterday. There were three of them in sight at one time, and they 

 were coming and going all day. The Blue Jays were around the col- 

 ony all the time, just outside the stripped area, and when seen were 

 eating both pupse and larvae. They are so shy that it is very hard to 

 get near them. There were a great many Chickadees 

 flying back and forth through the colony. Each one 

 would stop now and then, take a larva from the trunk, 

 take it to a branch, and with its feet on the larva would 

 pull it to pieces and eat it. A pair of Phcebes came to 

 the colony about 8 o'clock and remained nearly two hours, and caught 

 all the male moths that came near them. One of the Great-crested 

 Flycatchers was in and out of the colony at intervals all day, taking 

 food to its young in a hollow apple tree near by. I saw the pair take 

 all forms of the moth to-day, caterpillar, pupa, and male and female 

 moths. They would hop along on a branch, and at a distance might 

 be taken for Robins. I saw them take five pupse, two larvos, and two 

 female moths, besides a great many male moths, and carry them to 

 their young. A Kingbird also came, remained nearly half an hour, and 

 took many male moths. 



JULY 13. The Crows were in the colony when I arrived, and all 



1 Most birds leave the defoliated woods during the hotter part of the day, re- 

 tiring to the cool shade, and feeding in the stripped woods mostly at morning 

 and night.
