Springtime is full of activity as ducks try to attract the attention of the opposite sex. Males attract females with their vibrant colors.
The female common mergansers don’t change their plumage much, if at all.
But their attitude seems to change quite a bit during courtship. They choose a mate and chase the other males away. Sometimes it looks like she’s even grouchy with her mate though.
(By the way, I don’t have any control over what videos Youtube displays after mine. Please tell me if it shows offensive video choices.)
When it’s time to mate, though, the female gets very quiet.
She probably laid stretched out in the water for about 5 minutes before her partner was ready.
