19 Winning Photos From Nat Geo's 2016 Nature Photographer Contest That Will Inspire Your Next Trip

"This shot was taken on an early September afternoon along the riverbank at Pasir Ris Park in east Singapore. I was hoping to capture wildlife in action when some movement in the bushes nearby caught my attention. Instinctively, I prepared my equipment to capture any action that might ensue. I was fortunate enough to witness this adult crow chasing an adult buffy fish owl right in front of me, proving at once that the crow was the more aggressive species of the two. The entire spectacle between these day and night creatures lasted less than two seconds and exemplified nature in its uninhibited form."
