Although flying has become a rarity among domesticated duck breeds, there are some exceptions like Muscovies, Calls, East Indies and Mallards. Not all ducks can fly, however, and the soaring capabilities of ducks vary depending on the breed and its environment.
The main reason some birds can’t fly is their weight. Pekin ducks are too heavy to fly because their diet causes them to gain weight, grounding them. Smaller and lighter Pekin ducks might take short flights, but they can’t soar as high as mallards.
How Do Soaring Ducks Fly?
The ten longest and stiffest feathers on a duck’s wings, farthest from the body, are called primary feathers. They are essential for flying. Domestic ducks, restricted from flying for food and breeding, have these feathers clipped.
The shorter flight feathers on the “forearm” bone, called secondary feathers, work to create lift. As the wings flap upwards, the primary feathers open to let air pass, while the secondary feathers push air up from beneath.

Pekins, Rouen, Cayuga, Welsh Harlequin, Indian Runners, and Buff Orpington ducks don’t usually fly well (except in rare cases).
What Breed Can Fly The Highest?
Scientists have observed a brown and orange duck, similar in size to a mallard, flying at altitudes of 6,800 meters to cross the Himalayas.
Researchers at the University of Exeter used satellite data from 15 ruddy shelducks to discover that this species is the highest-flying duck known.
