• These small ducks are long distance fliers! They spend their summers in North America, from southern Alaska, across Canada to the East Coast. In the fall, they migrate down to South America, sometimes as far south as northern Chile and Argentina! They are one of the first to migrate in the fall and one of the last to return in the spring.
