Got it!


Many birds


make a slow-


moving river their


hunting ground,


snatching small fish


from the water. The


kingfisher is a colourful


inhabitant of many


European rivers.


The flowing current


Changing the landscape


Over millions of years, rivers cut channels in


the earth. A notable example of this is the


Colorado River and the Grand Canyon.


The fish is held
in the bird’s
dagger-like beak.


The kingfisher
will dive to about
25 cm (10 in) to
grab a fish.

Against the flow
Swift-flowing water
captures oxygen, helping
fish to breathe. Chinook salmon
swim against the current heading
for their spawning grounds. It’s a
dangerous journey.

A brown bear is
drawn to the river
by the presence
of salmon.
