The salmon run is the time when salmon, which have migrated from the ocean, swim to the upper reaches of rivers where they spawn on gravel beds. After spawning, all Pacific salmon and most Atlantic salmon die, and the salmon life cycle starts over again. The annual run can be a major event for grizzly bears, bald eagles and sport fishermen.

Salmon spend their early life in rivers, and then swim out to sea where they live their adult lives and gain most of their body mass. When they have matured, they return to the rivers to spawn. Usually they return with uncanny precision to the natal river where they were born, and even to the very spawning ground of their birth. It is thought that, when they are in the ocean, they use magnetoception to locate the general position of their natal river, and once close to the river, that they use their sense of smell to home in on the river entrance and even their natal spawning ground.

In northwest America, salmon is a keystone species, which means the impact they have on other life is greater than would be expected in relation to their biomass. The death of the salmon has important consequences, since it means significant nutrients in their carcasses, rich in nitrogen, sulfur, carbon and phosphorus, are transferred from the ocean to terrestrial wildlife such as bears and riparian woodlands adjacent to the rivers. This has knock-on effects not only for the next generation of salmon, but to every species living in the riparian zones the salmon reach. The nutrients can also be washed downstream into estuaries where they accumulate and provide further support for estuarine breeding birds.

Interesting visual, the birds enjoying the salmon lost or disoriented. Beautiful image and good composition

This series were taken by my first digital camera in almost ten years ago (2002). To pursue this wonderful view, we drove a car for over thousand km distance in Canada. Though the photo quality cannot compete with the one taken by the camera released in the past few year. This photo is still one of my best favorites. It invokes many great memory with my family then.

MF. Suggested a more correct location for this photo too. I see that you state these were taken in 2002. A big sockeye salmon run year. 2006 was the next big year. You should have seen 2010!! Largest run that I have ever seen here. Almost no fish this year. Will have to see what happens in the next major run in 2014.
