Two Against One

I was going to take some photoes about ducks and doves. And I went to river near the city.... I was wondering, why the ducks were not in the water. I took some pics and heard all the time some strange little voice.... and then one man there said to me: Look, its there again, Quick, use your cam!!! And there were they... two otters and one duck. Duck was fighting for his life... and he lost that :(
I was little late with adjustments, so pic is not so clear.. but havnt never seen this kind, so thats why I put this here....................
I like otters, but this wasnt so nice to see and hear...ANd most of all, almost in the centre of city.. that was a big surprise !
