An image of two mice fighting on a London Underground station platform has won the Wildlife Photographer of the Year LUMIX People's Choice Award.
The perfectly timed shot of the 'station squabble' is a portrait of urban wildlife that took Bristol-based photographer Sam Rowley a week to capture.
Mr Rowley's image was selected from a shortlist of 25 images that were chosen by the Natural History Museum from more than 48,000 entries for the 2019 competition.
Wildlife Photographer of the Year is developed and produced by the Natural History Museum, London.
The image will be displayed in the Wildlife Photographer of the Year exhibition at the Natural History Museum until it closes on 31 May 2020.
The mice were fighting over a few leftover crumbs, and their encounter lasted just a split second before one scurried away, triumphant.
Sam visited multiple platforms every night over the course of a week, and was the subject of curious looks from passengers as he lay on the ground waiting for the perfect shot.
When he saw the mice coming for the crumbs, he knew his patience had paid off.
"I'm so pleased to win this award. It's been a lifetime dream to succeed in this competition in this way, with such a relatable photo taken in such an everyday environment in my hometown," he said.
"I hope it shows people the unexpected drama found in the most familiar of urban environments."
Director of the Natural History Museum, Michael Dixon, said Sam's image provides "a fascinating glimpse into how wildlife functions in a human-dominated environment".
"The mice's behaviour is sculpted by our daily routine, the transport we use and the food we discard. This image reminds us that while we may wander past it every day, humans are inherently intertwined with the nature that is on our doorstep - I hope it inspires people to think about and value this relationship more," he said.
