Snow Goose
Anser caerulescensAlso known as Blue Goose, Lesser Snow Goose, Greater Snow Goose, Wavey
Flocking by the tens of thousands, snow geese create sweeping white blizzards across North American flyways during migration, filling the air with a constant, high-pitched chorus of nasal barks. Adults mate for life and nest in dense colonies across coastal Arctic tundra, where both classic white and slate-gray 'blue' morphs interbreed freely. Their voracious feeding style of digging up roots and rhizomes has profoundly reshaped fragile northern coastal ecosystems as continental numbers have surged.

Responsible observation
- Flock Etiquette: Remain inside viewing blinds or your vehicle along refuge drives to avoid flushing massive resting flocks.
- Scanning Flocks: Use spotting scopes to search white aggregations for dark-phase blue morphs and the stubby-billed Ross's goose.
- Timing Migrations: Plan visits to key migratory stopover wetlands during peak November and March flight windows.
