Daniel Trim’s airport-roosting pied wagtail has won the 2017 competition, which celebrates the work of amateur and professional photographers and the beauty and diversity of British wildlife
Overall and urban wildlife category winner: Daniel Trim, Heathrow roostings
“In winter, pied wagtails roost communally in urban areas, both for protection and for the additional warmth given off by buildings and lights. This extra degree or two can make the difference in harsh weather.
Here, a single individual out of hundreds is silhouetted by the lights of Terminal 5 at Heathrow airport.”
