Wildlife photographer Sam Hobson, from Bristol, has been photographing peregrine falcons locally since 2011. Several of his shots have been used to illustrate the recently published book, Urban Peregrines, by Bristol peregrine expert Ed Drewitt.
"Before moving to Bristol at the end of 2010 I'd only seen peregrines a handful of times and always at a distance. Soon after moving I realised that I had two pairs pretty much living on my doorstep, which is when I became really interested," he said.
"I met Ed, the local peregrine expert through a joint fascination, and he helped me learn how to identify the peregrines' prey remains.
"Together we have found all kinds of strange birds on the peregrines' menu, including woodcocks, lapwings, jack snipes, golden plovers, cuckoo and other usually rural birds right in the middle of Bristol - caught by the peregrines as they migrated over the city at night."
