BRANTA CANADENSIS, WILD GOOSE. 553 



upon aquatic insects, small molluscs, and marine invertebrates of vari- 

 ous kinds; for tliey are often observed on mud-flats and rocky places by 

 the sea-side, where there is no vegetation whatever ; and it is probable 

 that when they pass over meadows they do not spare the grasshoppers. 

 Audubon relates, that in Louisiana he has often seen the Geese feeding 

 in wheat-fields, where they plucked up the young plants entire.

Hab. — Arctic America. South to Sau Francisco in winter. 



This curious little Chen, in which a long-lost species is perfectly recog- 

 nized, is an inhabitant chiefly of Arctic America, but, like the Snow 

 Goose, is now known to migrate into the United States in winter. It 

 has been taken at San Francisco. With exactly the coloration and form 

 of A. hyperboretis, it is immediately recognized by its small size, being 

 no larger thau a Mallard, less exposure of the teeth of the bill, corruga- 

 tion of the base of the bill, and the nearly straight instead of strongly 

 convex outline of the feathers at the sides.

This proves to be a perfectly distinct species from A. Jiyperhoreus, the 

 young of which, however much resembling it, is quite different. In 

 adult plumage it bears a curious superficial resemblance to Philacte 

 eanagica, the distribution of the colors being much the same. Speci- 

 mens are in the Smithsonian from Chicago, and various localities in 

 North America, where its distribution is apparently general.
