Watching like a Hawk: Preston Bus Station's Pigeon patrols

There's a new sight at Preston's grade-II listed Bus Station.

Much to the surprise of commuters they've brought in three hawks to swoop on the troublesome pigeons who love nothing better than spending the day there!

The idea is to scare them away before they cause anymore damage to buildings or leave unwelcome deposits on the shoulders of passengers.
