Snow goose

The snow goose (Chen caerulescens) is a North American goose with white and dark color morphs. It breeds in the Arctic and migrates to wintering grounds farther south.

Chen caerulescens: Chen caerulescens is the scientific name of the snow goose, a species of Arctic-breeding North American goose. This is the species name used in scientific classification.
Bird migration: Bird migration is the regular seasonal movement of birds between breeding and nonbreeding areas. Snow geese travel between Arctic nesting grounds and southern wintering areas.
Light goose conservation order: The Light Goose Conservation Order is a United States management program permitting additional harvest of specified overabundant light geese. It was established to reduce populations that were damaging Arctic breeding habitat.
Overabundant species: An overabundant species has a population large enough to cause substantial ecological, economic, or social effects. Some snow goose populations have grown beyond levels considered sustainable for their breeding habitats.
White morph: The white morph is the snow goose color form with a white body and black wingtips. It is the familiar plumage form that gives the species its common name.
Atlantic Flyway: The Atlantic Flyway is a major North American migration route extending along the continent’s eastern side. Snow geese from eastern populations use this route during seasonal movements.
Arctic coastal plain: The Arctic Coastal Plain is a low-lying region of northern Alaska characterized by tundra, wetlands, and permafrost. Snow goose colonies and feeding grounds occur in this sensitive northern landscape.
Arctic ecosystem: An Arctic ecosystem is a community of organisms interacting with the physical environment of the polar region. Intensive goose grazing can reshape vegetation and affect other organisms in this system.
Blue morph: The blue morph is a dark-bodied color form of the snow goose, usually with a white head. It is the species’ alternative color form, not a separate species.
Mississippi Flyway: The Mississippi Flyway is a North American migration route following the Mississippi River basin and adjacent regions. Many snow geese move south through this corridor.
