These handsome waterfowls breed in temperate Eurasia and migrate to subtropical areas in the winter.
In the breeding season, the male Shelduck's bill appears bright red and bears a prominent knob on its forehead.
One or two adult Shelducks are often seen with a very large flock of young - this group is likely to be a creche into which most breeding parents will leave their partially grown offspring.
To protect the young ducks from predators, an adult Shelduck will fly away as a decoy while the young duck will dive under the water.
