Brown bear (ursus arctos) and red salmon (oncorhynchus nerka)
I watched this female brown bear capture many red salmon in the Brooks river of Katmai national park, in southwest Alaska. She had one cub of the year to feed, who watched from the river bank keeping alert for other bears. This picture was taken at a focal length of 700mm, which makes it seem closer than it actually was, but even still, I happened to be in a position that did not allow for me to back up easily, which sometimes happens photographing bears. The bear had approached me while chasing fish in the river, so I grabbed a few shots before she walked back to the bank to feed her cub. Photographing a moving subject, in low light, with a long lens resulted in many out of focus shots. The depth of field is very narrow at f/4 at this distance, and the eye needs to be sharp. This was a successful one, and I liked how it reveals the dexterous manner in which the bears can handle fish, she is holding it with her teeth by the dorsal fin.
