and the juvenals answered, jumping against the sides of the 

 cage. An old bird brought amelanchier berries and it was 

 back again with more at 2 :10, 2 :20 and 2 :40. 



August 4, 8:00-9:40 A. M., 1:15-2-15 P. M. 



The maximum temperature on August 4 was 90 degrees. 

 At 8 :00 the birds were peeping loudly and being answered. 

 A parent approached with a blue berry two- minutes later, but 

 flew off without giving it to them. The juvenals flew against 

 the side of the cage and kept on calling, while one raised its 

 crest. At 8 :05 a parent approached with amelanchier berries, 

 which it gave them and left, returning with more berries, 

 the two feedings taking less than half a minute. By 8 :08 the 

 birds were quiet and preened their feathers, each placing its 

 bill under its wings and tail. At 8 :10 the larger young bird 

 began to chirp again, but I heard no answer. A parent 

 brought blue berries five minutes later and each young bird 

 ate one. The juvenals were fed again by a parent at 8 :i8 

 and then I cleaned the cage. When we touched the young 

 birds they showed no signs of fear. At 8 :25 they were back 

 on their perch and eight minutes later a parent bird brought 

 two amelanchier berries. Half a minute after it fed them it 

 was back with more. At 8 :38, after shaking out their feath- 

 ers and pecking at the bars of the cage the juvenals settletl 

 down to sleep and remained so until 8 :45, when they picked 

 at their wings. A parent gave them each a berry at 8 :55 and 

 then dropped a large one at the bottom of the cage, which a 

 young bird picked up and ate. This was the first time I no- 

 ticed the young- feeding themselves. After this they showed 

 this ability constantly, putting their heads through the bars 

 to reach a berry dropped outside. At 8 :58 and 8 :59 they were 

 fed amelanchier berries by a parent. The young- birds rubbed 

 their bills against the bars of the cag"e as if to clean them. 

 Five minutes later they were dozing', close together on the 

 perch. At 9 :30 the parent brought a large insect of some 

 kind. This was the first time that I had seen animal food 

 brought by a parent since we caged the young birds. At 9 :32 

 a parent brought blue berries and flew back again for more.
