In the US, if you stop by a pond or lake, you’re likely to see a mallard or a Canada goose. They’re hard to miss: male mallard ducks have bright green heads, while the females are brown, with some purple feathers on their wings. Canada geese, meanwhile, have long black necks and wingspans reaching up to six feet. But these are just two of the 147 species of ducks, geese, and swans in the world.

Members of this family are found all over the world– there are even ducks that make their way to the coastal parts of Antarctica. And while we’re used to seeing geese on golf courses and corporate parks, some geese travel to more exciting destinations. The bar-headed goose in central Asia has been reported flying over Mount Everest, more than five miles above sea level!
