A question has been puzzling me for a long time and the answers I’ve found on the Internet are unsatisfactory, so I’m asking you.
What is the difference between a duck and a goose?
Does a goose have a longer neck or legs? Not always. Consider these black-bellied whistling ducks.
When we see a duck or a goose, intuitively we are able to say, “That’s a duck” or “That’s a goose.”
But how do we know the difference?
Please let me know by posting a comment.

UPDATE: Chuck Tague wrote in the comments: “The difference is social structure. Ducks are seasonally monogamous and form a bond that lasts only through courtship and the initiation of incubation. The male takes no role in raising the young. Geese and swans form strong bonds that last for many seasons (or life) and maintain family units through migration. Whistling ducks are closer to geese than ducks.”
See the other comments, too! Lots of great information.
