Harlequin Duck:
IUCN Listing: Least Concern - increasing population

Foraging Technique: Diving
Breeding Habitat: Fast flowing rivers and streams away from the salty oceans they spend most of their time in
Nesting Preference: Nest close to a stream in high cover on the ground
Average Clutch Size: 6 eggs
First age of Breeding: Second or third winter
