236 Honywill, Birds of the Crooked Lake Region, Minn. [April 



first houses were replaced by new ones. There were perhaps twelve pairs 

 of birds nesting about the camp, although the exact number could not be 

 ascertained. This year another house was erected and a further increase 

 of the flock noticed. A few days before they left this fall I was able to 

 count over fifty birds, and without doubt there were more. Average date 

 of departure, August 25. Latest seen August 29, 1908. 



63. Petrochelidon lunifrons lunifrons. Cliff Swallow. — A few 

 occasionally seen in the fall. 



64. Hirundo erythrogastra. Barn Swallow. — Never seen in the 

 immediate vicinity of Crooked Lake, but observed along the road to Pine 

 River, where the country is more settled. 



65. Bombycilla cedrorum. Cedar Waxwing. — Common. On 

 Aug. 4, 1908, four young birds were found that were not quite able to fly. 

 While arranging them to be photographed one of the old birds came and 

 fed them. The old birds appeared to be fearless, and fed the young ones 

 blueberries and wild cherries while I held them enclosed in my hands, 

 and even tried to get to their young when I pushed them gently aside. 

 Nests were sometimes located in the Norway pines, from the noise made by 

 the young in calling for food. Usually these nests were placed upon the 

 extreme ends of the branches and were inaccessible. They were generally 

 composed almost entirely of usnea moss. 



66. Vireosylva olivacea. Red-eyed Vireo. — Very common. From 

 August 21 to 24, 1910, large numbers of migrants were seen. 



67. Mniotilta varia. Black and White Warbler. — One was heard 

 singing on Aug. 11, 1910. Migrants were fairly common on, and for a few 

 days after, the twenty-first of the month. 



68. Vermivora rubricapilla rubricapilla. Nashville Warbler. — 

 A bird was seen in the second growth near the bank of a small lake on 

 August 17, 1910. and was identified as belonging to this species. 



69. Dendroica aestiva sestiva. Yellow Warbler. — Not uncom- 

 mon along the borders of the lakes. 



70. Dendroica pensylvanica. Chestnut-sided Warbler. — Rather 

 rare summer resident; more common after the middle of August. 



71. Dendroica virens. Black-throated Green Warbler. — I 

 have never observed this bird in the pines around the camp, although I 

 have heard the song on the drive into camp. 



72. Dendroica vigorsi. Pine Warbler. — Quite often observed in 

 the pines near the camp, where it probably breeds. 



73. Seiurus aurocapillus. Ovenbird. — Common. 



74. Seiurus noveboracensis noveboracensis. Water Thrush. — 

 Quite common from August 24 to 27, 1910, when it was observed in the 

 birch woods as well as along the water's edge. 



75. Geothlypis trichas trichas. Maryland Yellow-throat. — 

 Abundant. 



76. Wilsonia canadensis. Canada Warbler. — Migrants were 

 seen on August 21 and 24, 1910.
