How can a duck drown?

Ducks can drown or look like they are drowning when they are mating or - the obvious answer - fighting.

Male ducks ( Drakes) will fight each other for mates and if you observe them will sometimes try and mate with a female in water..this looks like he is drowning her.

Female ducks will sometimes (I have seen this with my own eyes) try to drown another duck's ducklings. This is a horrible sight. The cause of these 'killings' is the natural instinct to survive. The mothers both want their ducklings to have the best chance of survival.

I hope this has helped you!
