According to several observers, the Eedstart is one of the commonest 

 birds along the Missouri River bottoms, breeding abundantly. Dr. 

 Cooper obtained numerous nests at various points between Fort Union 

 and Milk Eiver, and traced the species westward to the Cceur d'Al'ene 

 Mountains. Mr. Allen says it occurs with considerable frequency as a 

 summer resident in the foot-hills west of Denver, where it evidently 

 breeds, and is doubtlessly sparingly represented wherever there are 

 woodlands or thickets, thence eastward to the Atlantic coast, as well as 

 westward throughout the lower mountain valleys, as he found it com- 

 mon about Ogden, Utah, in autumn. In the mountains be did not observe 

 it above 8,000 feet. 



The Eedstart builds an elegant little nest in the fork of a tree, of va- 

 rious soft downy substances matted together, and usually also with 

 fibrous strips. Those built chiefly of down are d*c[uisitely soft and 

 neatly finished with a firm, smooth, circular brim, quite narrow. The 

 interior is lined with a considerable quantity of very fine rootlets, or 

 horse-hair, or both, for the most part circularly arranged. The whole 

 nest is only about two and one-half inches across outside, and the same 

 in external depth; 'the cavity is usually rather deeper than broad. A 

 nest taken at Racine, Wisconsin, by Dr. Hoy, is curiously fixed entirely 

 to one side of an upright fork, setting away from the support altogether, 

 excepting on a small part of its circumference, which is Continued down- 

 ward into the crotch, and to which the rest of the nest is attached more 

 intimately than it is to the fork itself. Bbe eggs, in the examples before 

 me, are mostly four in number ; they are white, quite thickly sprinkled 

 all over, but especially spotted at or around the large end, with usual 

 shades of brown and lilac. Different specimens measure from 0.00 by 

 0.49 to 0.70 by 0.51. The bird breeds in Kansas, and also very abundantly 

 along the Red Eiver, in June.
