quently noted in the burned lands, but had practically disappeared by August 

 16. It was seen most frequently in the wild cherry trees as the fruit ripened, 

 where it fed in company with the cedar waxwings. It was often noted in 

 the dense poplar growths. 



86. Hylocichla guttata pallasi. Hermit Thrush. — This thrush was often 

 seen about the !)urned lands and the margin of the hardwood forest. It 

 was very shy, but the clear sweet song of the male even in the hotter parts 

 of the clay proclaimed its presence. , It was rarely noted after the tenth of 

 August. 



87. Planesticus migratorius migratorius. Robin. — The robin was common 

 thruout the burned lands during the summer. Its numbers decreased no- 

 ticeably after August 13, but many individuals were still present when we 

 left the region, August 24. Two nests found on July 2 and 23 each con- 

 tained three young birds nearly ready to fly. 



88. Sialia sialis sialis. Bluebird. — This species was frequently seen in 

 both July and August. It avoided the unburned areas, and bred commonly 

 in the burn where trees had been left. There were always plenty of aban- 

 oned woodpecker holes and other hollows for nesting sites in these places. 

 In August the birds were often found feeding high up in the groves of un- 

 burned pines in company with the chipping sparrows. Young birds just 

 able to fly were recorded on July 6, and from that date till the sixteenth 

 young birds in various stages were frequently seen.
