BEAR AND FOX IN SHOWDOWN

This is the moment a nimble red fox and a lumbering Alaskan brown bear were locked in a tense stand-off. The 500lb bear confronted the fox on the tidal flats of the Katmai National Park in southern Alaska. After a short chase, where the quick-footed fox deftly outmanoeuvred the bear, the two animals sat completely still and waited for the other to make a move. American photographer Nate Zeman witnessed the scene in the Alaskan national park after he saw the bear emerge from a nearby forest and approach the fox.
