Canada goose

• One of nature’s great spectacles: thousands fill - The flyways on their journey south in autumn
• Travels in V-formations, creating slipstreams - To minimize the effort of migratory flight
• Has a built-in compass to aid navigation when Clouds obscure landmarks and hide the stars

WHERE IN THE WORLD? Breeds across northern North America; winters farther south in the U.S. And Mexico; introduced into Britain, Scandinavia and New Zealand.
