Bears eat salmon they catch while the salmon are traveling upstream to their spawning grounds. The 'spawning run' for most North American salmon species starts in late spring or early summer and ends in the fall, October or November, in most spawning grounds.
The spawning area of salmon is called a "spawning ground" or "spawning bed," where female salmon lay their eggs and male salmon fertilize them. These areas are usually located in freshwater rivers or streams where salmon return to reproduce.
