1 1 ERE i^ another of those Hyperborean strangers, of which we know al- 

 most nothing, save thai now and then one ventures upon our hospitality and is 

 promptl) betrayed. Dr. Wheaton was the first to record the species for Ohio. 

 having identified two in Columbus in 1875. On October 28, 1896, a pair 

 were taken en the water-works reservoir at Oberlin; and other records have 

 since been made. 



Samuel Hearne, writing more than a century ago, clearly distinguished 

 this species from the Snow Goose (C. hyperborea nivalis) but later writers, 

 including Audubon, fell into the mistake of regarding it as the young of the 

 other species, and the Blue Goose was for a long time lost to view. During 

 migrations the two species are not infrequently found together, and the mis- 

 take w as n, .t unnatural. 



"i:> Indian report the great breeding ground of the carulescens is the 

 countrj lying in the interior from the northeast point of Labrador. Exten- 

 sive swamps and impassable bogs prevail there, and the Geese incubate in the 

 lid and driest tufts dispersed over the morasses, safe from the approach 



an or any other than a winged enemv" 1 Brewer).
