You know how geese fly in a “v” shaped pattern in the sky? One side of the “v” is usually longer than the other. The reason for that is that there’s more geese on that side.
You can tell by the way it is!
They do it for efficiency, like ducklings after their mother. Have you ever seen a large boat from above? The wake spreads out behind it, in this v-shape. It's like a wave following the boat, and the ducklings can "surf" on the v-shaped wave, after their mother, and they don't have to paddle as hard.
And the name of that shape is a chevron.
