A goose moves through water using paddling, gliding, and buoyancy:
Paddling: Webbed feet create a larger surface area for propulsion. Geese use both front and rear legs, with power strokes pushing backward and recovery strokes folding the toes to reduce drag.
Gliding: After gaining momentum, geese may paddle less and rely on their streamlined bodies to glide effortlessly.
Buoyancy: Air sacs and hollow feathers trap air, helping geese float and reducing overall density.
By combining these techniques, geese move efficiently and gracefully in aquatic environments.
