169.1. Chen caerulescens (Linn.). Blue Goose. 



Anas caerulescens. A nser caerulescens. Blue-winged Goose. Young of 

 Snow Goose. 



Geog. Dist. — Interior of North America. Breeding ground 

 unknown but thought to be on eastern shores of Hudson Bay. 

 In winter through Mississippi \^alley to Gulf coast, chiefly west 

 of the Mississippi River. 



In Missouri the Blue Goose is a fairly common transient visi- 

 tant in spring in flocks by themselves or mixed with Snow Geese. 

 Available dates run from March 17 to April 2; no fall record is 

 at present at hand. Formerly considered to be the young or a 

 colored phase of the Snow Goose, this species did not receive 

 that measure of observers' attention which it deserves. More- 

 over the young of the two species resemble each other perfectly 

 in form and size, and enough in color to make identification at a 

 distance difficult. Both, old and young, were formerly not rare 

 in the St. Louis market. Two fine specimens of adult birds 

 are in the Eimbeck, one in the Hurter collection and some in 

 several other private collections in St. Louis.
