90 SIXTEENTH REPORT. 



77. Dumetella carolinensis. Catbird. — This species was seen frequently 

 during July, but had disappeared entirely by August 10. It reached its 

 maximum abundance during the last week in July. 



78. Toxostoma rufum. Brown Thrasher. — A few pairs of thrashers bred 

 in the burned lands, Init the species was rare. On July 8 to 30 two pair 

 were often seen about camp, l)ut were not recorded after the latter date. 

 They were extremely shy. A nest with four eggs was found in the burned 

 land, July 11. It was situated on the ground under a partly dead bush. 

 On July 29 it contained three young birds, which had fallen prey to some 

 enemy by August 2. The adults also had disappeared by that time. 



79. Troglodytes aedon aedon. House Wren. — This species was common 

 during the summer, becoming more abundant in the latter part. It was 

 often found in the burned cedar swamps, where, with the white-throated 

 sparrow, it often furnished the only visible bird life. All thru the burned 

 lands it was heard and seen daily, and even came into the willow thickets 

 along the river. A pair of wrens started to build a nest on July 3 in a stub 

 near camp. When it was completed, the birds abandoned it and built 

 another in the decayed end of a pine log in the side of the house, and here 

 raised their brood. The first young birds to be recorded were a family of 

 five in a burned cedar swamp on July 13. 



80. Nannus hiemalis hiemalis. Winter Wren. — This wren was heard al- 

 most daily in July and the first week in August, but after the sixth of Aug- 

 ust it rapidly decreased in numbers and was not recorded after the twelfth. 

 It frequented the densest of the river thickets, the depths of the unburned 

 swamps, and the lower, wet swales in the hardwood forest. It was most 

 typical of the first two habitats. Were it not for the loud, unmistakable 

 song of the males, the species could easily be overlooked, as it is extremely 

 shy. 



81. Certhia familiaris americana. Brown Creeper. — This species was seen 

 but rarely. The first record was made on July 10 when a single bird was 

 found among the hemlocks. A juvenile bird taken August 9 at the edge of 

 the forest was the last record. 



82. Sitta carolinensis carolinensis. White-breasted Nuthatch. — This spe- 

 cies was seen occasionally during the summer, usually in the hardwood 

 forest, more rarely in the burned lands where a few trees had remained 

 standing. 



83. Penthestes atricapillus atricapillus. Chickadee. — The chickadees 

 were rarely seen far from the unburned cedar, spruce and tamarack swamps 

 in July In these places, however, they were commonly seen and their 

 notes were freciuently heard when the l)irds themselves were invisible. As 

 August advanced, they were found more frequently in the hardwood forest 

 and among the hemlocks. They fed there in company with the warblers 

 that had left the river thickets, and very frequently flocks were located by 

 the chickadee's note. Rarely the species was observed in the burned lands, 

 and rather more frequently in the river thickets. On July 19 a family of 

 five young just able to fly, in company with the two adults, was seen in 

 an unburned spruce swamp near the beaver meadow. After this date, 

 several other broods were ol)scrved. 



84. Regulus satrapa satrapa. Golden-crowned Kinglet. — Two individuals 

 of this species were seen on July 23 in the hemlocks. They were with a 

 small flock of chickadees and warblers. The one collected was a juvenile 

 male. 



85. Hylocichla fuscescens fuscescens. Veerj'^ — This species was fre-
