Geese

Anser caerulescens
Open tundra for breeding; marshes, wet prairies, flooded fields on migration.
Ne Siberia on Wrangel I.and possibly the Chukotski Pen.; from n Alaska, e along the Canadian Arctic coast and islands to nw Greenland and Ellesmere and Baffin is., s to Southampton I. and Hudson Bay on both coasts s to James Bay.

The former recognition of two species, A. hyperboreus, the Snow Goose, and A. caerulescens, the Blue Goose, was based on treating the two color morphs as separate species.

Branta canadensis
Marshes, meadows, lakes, rivers, tundra; in migration also brackish coastal areas and bays. Relationships among breeding populations uncertain.
This complex consists of at least two species, a large one (canadensis) and a small one (hutchinsii).
B. canadensis breeds from n Alaska (exc. range of B. h. minima) and n Canada (exc. coastally e of Mackenzie) e to sw Baffin I. and Labrador, s to sc,se Alaska w to Alaska Pen., c Calif., n Utah, s Kansas, n Texas, w Oklahoma, n Arkansas, w Tennessee, w Kentucky, c Ohio and se Canada, formerly to New England. There is an east to west color cline of light to dark populations which also differ in size.
The named races, east to west, include canadensis, interior, maxima, moffitti, parvipes, fulva and occidentalis.
Resident populations now established in many areas s of original breeding distribution.
Introduced (primarily canadensis) in w,n Europe, Sardinia, New Zealand.
