374 NOliTII AMERICAN BIRDS. 



This species was found breeding at Fort Resolution, latitude 02°, by Mr. 

 Kennieott, the ne.st being in an alder-bush, and al)out live feet from the 

 ground. It was also found nesting in the same locality by Mr. Ross and by 

 Mr. Lockhart. Its nest was found at Lake Manitobah by Mr. McTavish, 

 and at Fort Simpson by Mr. lloss. 



This species has been gradually undergoing certain modifications of habits 

 and manners in conse([uence of its contact with civilization and becoming 

 familiarized to the society of man. In nothing is this made more apparent 

 than in the construction of its nests. Those made on the edge of woodlands 

 or in remote (orchards are wrought almost entirely of line deciduous bark, 

 hempen fibres of vegetables, feathers, dried fragments of insect cocoons, and 

 other miscellaneous substances felted and impacted together ; within this is 

 a lining of tine strips of vegetable bark, woody fibres, fine lichens, and soft 

 downy feathers. In some the lining is exclusively of fine pine leaves, in 

 ot lid's with the seeds or pappus of compositaceous plants. The nests are 

 always quit(; small, rarely measuring more than three inches in diameter or 

 two in height. Those made in the vicinity of dwellings indicate their neigh- 

 borhood by the variety of miscellaneous and convenient materials, such as 

 bits of paper, rags, cotton, wool, and the larger and more conspicuous feath- 

 ers of ihe poultry-yard. AVhere raw cotton was abundantly provided, I have 

 known thin material, strengthened with a few straws and woody fibres, with 

 a lining of fea<^^^'^^« constitute the whole substance of the nest. 



..^.-sL, constructed in a thick tamarack swamp in Wisconsin, is com- 

 posed of a dense, impacted mass of a dirty white vegetable wool, inter- 

 twined at the base with shreds of bark, vegetable stems, and small black 

 roots. The inner rim and frame of the nest are made of black, shining root- 

 lets, intermingled with slender leaves and stems of dry sedges, and lined 

 with the pappus of a small composite plant and a few feathers. 



The eggs of this species are pure white, never, so far as I am aw^are, spot- 

 ted, of a rounded-oval shape, nearly equally obtuse at either end, and meas- 

 uring about .60 of an inch in length by .50 in breadth.
