Behaviour |
Social behaviour: Communal | Mobility: Nomadic/dispersive | Elementary unit: Pair/flock |
Hardheads are known to be diving ducks and have been observed by us to do so. They can stay under water for a considerable time (30 seconds and more) and over considerable distances (100 m or more).
Especially outside the breeding season Hardheads can form large flocks;

Birds that are preyed upon by raptors have wide-angle vision, i.e. their eyes are on the sides of their heads. When checking their surroundings, they typically look at things sideways, as shown in the photos below.
