Pike in the area?

A couple of fishermen were further along the river and for some reason there were lots of ducks all along the bank. It must be predator fish, the water was too cold or something - it was a little different to see them all like this.

I have had a strange thing tonight. Came home at 23.11 to find my neighbours from hell having a meeting at one of the lorries but they seemed to panic and disappear as I got out of my car. How odd.
