NORTH AMERICAN BIRDS. 433 



doubtful breeding bird in Central Ohio, has lately proven to be 

 quite common during the summer months. I took a nest May 27, 

 1885, in the characteristic position at the base of a sapling in swampy 

 woods. The nest is of the usual type, composed of leaves, strips of 

 grapevine bark, weed stems, and lined with black rootlets. This nest 

 contained three eggs of its owner and one of the Cowbird. 



An illustration of a Wilson's Thrush's nest appears in Jones' mag- 

 nificent work, "Nests and Eggs of Birds of Ohio," which was taken 

 May 21, 1884. Dr. Jones took another nest which was placed at the 

 base of the leaf of the skunk-cabbage plant, eighteen inches from the 

 ground, at the edge of swampy woods. Nests of this bird have been 

 found in hollow trunks of trees, fifteen feet from the ground, and in old 

 tin cans lying on the ground in the woods. The eggs are four or five 

 in number, and are plain, pale greenish-blue ; average size, .87 x .64.

Willow Thrush. 



i 

 Hab. Rocky Mountain region of the United States, east casually during the migration to Dakota. 



Minnesota, Illinois, etc. 



The Willow Tawny Thrush inhabits the lower willowy portions of 

 the Rocky Mountain region in United States. Habits, nests and eggs 

 are similar to those of Wilson's Thrush. Eggs, .85 x .66. 



757. Turdus alicise BAIRD [3.] 



Gray-cheeked Thrush* 



Hab. Eastern North America, west to the Great Plains, Alaska, Eastern Siberia north to the Arctic 

 coast. In winter south to Costa Rica. 



The Gray-cheeked Thrush breeds from Labrador and Hudson Bay 

 north to the Arctic coast and the coast of Bering Sea. It has been 

 found breeding abundantly in the Mackenzie River region and on the 

 Anderson River. The nests were found, with all but few exceptions, 

 on the branches of low trees, from two to seven feet from the ground. 

 In a few exceptional cases they were built on the ground. They 

 are usually compact, and composed of an elaborate interweaving of 

 fine sedges, leaves, stems, dry grasses, strips of fine bark and lined 

 with fine grasses. Occasionally nests are found constructed with mud, 

 like those of the common Robin. 



The eggs are usually four in number, and are greenish-blue, 

 marked with spots of russet and yellowish-brown. Capt. B. F. Goss 

 has two eggs of this species, taken by Mr. R. R. MacFarlane, at Fort 

 Anderson, Arctic America. The nest from which these were taken 

 was placed in a low tree. The eggs are greenish-blue, faintly marked 

 over the entire surface with reddish-brown- Their sizes are .91 x .71, 

 ,91 x-72.
