second bird, which fed the little birds. At 4 :10 the first bird 

 left while the second bird sat on the side of the nest with its 

 mouth open. The station thermometer registered 86 degrees 

 that day. At 4:30 the parent preened the feathers on its 

 breast. 



July 23, 8 :30-10 :40 A. M,. 

 The sun was very bright and warm, the temperature reach- 

 ing 90 degrees in the shade. At 8 :35 the parent bird was not 

 on the nest. The nestlings had downy feathers on their breasts 

 and showed definite feathers an inch long on their wings and 

 tail. On their backs the apteria showed plainly. At 8 :50 the 

 ^second bird returned with an insect, which it gave to the little 

 birds. At a noise from the laboratory it flew off, uttering one 

 shrill note and was absent until 9 :15, by which time the lit- 

 tle birds had become very much excited. When the second 

 bird approached it showed no food in its bill, but soon regurg- 

 itated two blue berries. Several people approached and the 

 birds seemed excited, but it remained on the nest. At 9 :40 

 the little birds kept stretching their necks upwards with their 

 mouths wide open and two minutes later the second bird 

 brought several blue berries, which it fed to each of the 

 young, and then perched on the nest. It was still there at 

 10 :35, when the first bird returned with a worm, which was 

 first given to the second bird, who swallowed it and later gave 

 a part to each little bird.

 As I approached the first bird came with food, which it 

 regurgitated and gave to each bird. It perched on a limb 

 near the nest, where it stayed for three minutes. At 11:03 

 it returned with a worm, which it first placed on the side of 

 the nest and pinched apart with its beak. Then it swallowed 

 the worm, which was regurgitated after a minute and fed to 

 the young, each receiving some food, although perhaps not all 

 a piece of the worm. At 11 :08 the bird flew away, but was 

 back in two minutes and fed each bird twice and then the 

 parent perched on the side of the nest for five minutes. In
