Photographer Sam Rowley’s image of two mice fighting over leftover food in the London Underground won People’s Choice Wildlife Photographer of the Year. The snap was selected by the public from more than 48,000 submissions to London’s Natural History Museum.

Entitled “Station Squabble,” the photo depicts how some wildlife have adapted to survive in urban environments.

“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,” says the 25-year-old photographer.

“I hope it shows people the unexpected drama found in the most familiar of urban environments.”

Rowley spent an entire week in the London Underground following the critters around and waiting for the perfect shot. Thankfully, he was rewarded for his patience.
