There was a flock of them swimming with Canada Geese. Perhaps 20 or 30. This is the second day I’ve seen them there.

Just before I could set my camera up I witnessed a Common Merganser mother of two, drop her brood off with a larger group. The mother of two headed up stream leaving her offspring with a single female Common Merganser who was already watching 15 young Mergansers. Because ducks forage for themselves from the day they are born, they don't rely on there parents for food. A mother Merganser who looks after multiple broods is also increasing her broods chance of survival from predator attacks. The more ducklings there are in a group the less of a chance one of her own will be a casualty.

Le Harle bièvre est un canard piscivore qui ne niche en France que sur les grands lacs Alpins (Annecy, Léman). Il fréquente volontiers les ports. Les Harles de cette vidéo ont été filmés en Suisse à Genève où ils sont assez faciles à observer.
