1This is going to be the end of the road for a lot of salmon.
2These bears are really hungry.
3They haven't tasted salmon for ten months
4and the big males battle for the best fishing spots.
5The longer the salmon take over their journey upstream, the weaker they become.
6And these falls present them with their biggest challenge yet.
7Although the falls aren't very tall, the bears hold the high ground.
8The salmon make short exploratory leaps to see where the bears are.
9But they don't always get it right.
10This mother bear has been waiting months for this moment.
11Competition is fierce for these first salmon,
12even between a mother and her own cubs.
13More and more fish arrive at the foot of the falls.
14Eventually, they have to go for it, regardless of the danger.
15...
16But numbers are on their side.
17For every salmon that gets caught, hundreds make it past the bears.
