At the end of winter ducks start to form couples and this means a lot of displaying that goes with it. At the Brouwersdam I was guiding a tour and we first trying to photograph three Long-tailed Ducks when this flock of Eider (12 males and a single female) came towards us.
So we sat down at the water level and waited for the birds to come our way. It was a fantastic sight. Males displaying, flapping their wings and chasing others away. Meanwhile she was in the center with the most dominant male pointing out the males he had to chase off.
This spectacle was right in front of us and very close. It was hard to focus with all the action going on so it was just a matter of shooting and see what comes out.
