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 Canada, Greenland, and Alaska 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 might pave its way across Canada and northern U.S. It can be observed even in New York. One may also see them resting side by side on a big lake covering the entire water's surface areas.
