Factual error: Grizzly bears and wolves are within the film. In reality, both of these animals were extirpated from Oregon at the time of the film's release.
Plot hole: Eagle catches and flies off with one of the cubs and Benji goes chasing after the eagle. After a bit of searching he spots what appears to be the missing cub but then Benji is chased by the nearby eagle before turning around to drive it off. But strangely Benji abandons looking for the fourth cub, as from this point forward we only see three cubs with him. This doesn't jive, as Benji has up to this point done everything to protect the cubs and keep all four of them together. (00:58:20 - 01:00:06)
