Widmann — A Preliminary Catalog of the Birds of Missouri. 187 



viduals are met with in winter in the vicinity of St. Louis in 

 company of other sparrows, and small troops winter regularly 

 in the sheltering; forests of southern Missouri. 



563a. Spizella pusilla arenacea Chadb. Western Field 

 Sparrow. 



Spizella arenacea. 



Geog. Dist. — Breeds from Nebraska and South Dakota to 

 eastern Montana; winters in southern Texas, Louisiana and 

 northern Mexico. 



Of the four specimens which Mr. E. Seymour WoodrufT col- 

 lected in Shannon Co. in March, 1907, he found ''two to be 

 undoubted arenacea, the other two intermediate between pusilla 

 and arenacea but nearer the latter, because of their longer wings 

 and tail and general paleness." 



567. JuNCO HYEMALis (Linn.). Slate-colored Junco. 



Fringilla hyemalis. Struthus hyemalis. Niphea hyemalis. Junco hiemalis. 

 Fringilla nivalis. Junco. Snowbird. 



Geog. Dist. — Eastern North America and through the interior 

 to the Arctic coast and Alaska ; breeding from the mountains of 

 Pennsylvania, New York and Massachusetts, from Ontario, 

 central Michigan, northern Wisconsin, northern Minnesota 

 northward to Labrador, western shores of Hudson Bay, to the 

 Arctic coast and the valleys of the Yukon and Kowak. Winters 

 from Connecticut, southern Michigan, Wisconsin and eastern 

 Nebraska southward to the Gulf coast, Arizona and Cali- 

 fornia. 



In Missouri a very common winter resident and transient 

 visitant, present fully one-half of the year. The first, exception- 

 ally early arrivals, have been noted at Keokuk, September 11, 

 1894, and September 25, 1899; at St. Louis, September 20 and 

 26, but usually the van does not reach Missouri before the first 

 week of October and St. Louis in some years not before the end 

 of the second week. The main body of the invading army comes 

 to our northern border in the second week of October, to St. 

 Louis about October 20th and to the southeastern corner of the 

 state about the last of the month. Transients throng the state 

 until the middle of November, after which winter numbers remain. 

 As the northern limit of their range varies in different seasons, so
