What Am I ?

Had a lovely day , went to Drymen and had a wee meander around there while our older grandson went for a job interview ( in 5th year at school and looking for weekend and holiday work ) ,Very pleased to say he got the job. Just as well he doesn't start tomorrow as he usually comes to the Sons game with us.

This evening we went for a run in the car to Aberfoyle spotted these ducks in a lochan so had to stop to blip them,this was one of my favourite blips of today. Not sure what kind o duck it is , any help with the ID would be much appreciated.

Large has some lovely detail

Enjoy the weekend.
