Behavior

  • They flap their wings to ward off predators.
  • Unlike other ducks, they rest on rocks instead of water.
  • During spring, their migration starts from coastline areas and ends in inland regions. Sub-adult ducks and if any members get injured, they refrain from further migration.

Mating and Reproduction

Around October male ducks dance by shaking both their heads and tails, producing a whistling sound to allure females who also look for potential mates who have the brightest plumage. Once a pair is bonded, the duo takes a short flight and engages in mating. The breeding occurs from May to June. Female ducks have 5-8 eggs in a clutch which they incubate all by themselves. The hatching starts after 27-29 days.

Life-cycle

Young ducks depend on their mothers to learn preying and it is around after 45 days they start flying on their own. Later on, upon reaching adulthood, the ducks and their mothers migrate to the coastlines. Some individuals stay connected to their mothers as both parties fly back to the same areas.
