Image of Cackling goose

Description:

Left foreground is a Ridgway's Cackling Goose (B. h. minima)hatch-year, right foreground an Aleutian Cackling Goose (B. h. leukopareia) hatch-year. Note that the Aleutian lacks the white collar that some observers believe is a good identification mark for this subspecies; the collar does not molt in until sometime in mid-winter. In the background is a Great Basin Canada Goose.
