The photos were taken at the Broadmeadow river, in Swords, County Dublin, Republic of Ireland.
Mr Marry said: “I was absolutely delighted when I got the set of photos as it was the result of a lot of months of hard work.
“I would sit and wait for hours with my camera and sometimes the bird wouldn’t even show up.
“I was starting to get downhearted and just when I thought about packing it all in it just happened. It was really special.”
