One hears them long before they appear in sight. The stunning, loud calls become louder and louder tearing the air apart—this means an immense cloud of wild geese is hurrying back home to Alaska, Canada, and Greenland after their winter stay as far south as Texas or Mexico.
The spring migration is way more impressive than autumn, as in spring the birds act more unified in a large stream. Flocks of snow geese set off north already in late February, and in March the migration is already at full speed.
The bird cloud paves its way across Canada and the northern U.S. In Alaska, you can spot migrating birds at the Matanuska Valley in the southcentral part of the state, not far from Anchorage. Copper River Delta and Stikine River Delta, in southeastern Alaska, are great locations to observe clouds of geese during both spring and fall migrations. A considerable population of snow geese stays to breed and build nests in Alaska. The largest colonies can be found in the northernmost North Slope region, where geese are attracted by rich cotton grass and huge open spaces. The Ikpikpuk River Delta and the Kukpowruk River delta host the largest colonies of these waterfowl over the summer.
