LedňáčekThe common kingfisher(Alcedo atthis)
You can see it all across Eurasia and North Africa.
By Eliska
It lives there, but it migrates from areas where rivers freeze in winter.
It feeds mainly on fish, caught by diving, and has special visual adaptations to enable it to see its prey under water.
It lays eggs in a nest at the end of a burrow in a riverbank.
The common kingfisher has no song. The flight call is a short sharp whistle, chee, repeated two or three times.

30 square km. They usually mark their teritory.
Vydra
OtterLutra Lutra
By David
They may inhabit any unpolluted body of fresh water, including lakes, streams,
rivers, and ponds, as long as the food supply is adequate. Eurasian otters may
also live along the coast, in salt water, but require regular access to fresh water
to clean their fur.
The otter is a great swimmer and diver. It can stay longer
than 5 minutes in the water, and can swim up to 400 m.
In one day the otter consumes large amounts of food. It feeds primarily with water animals, especially
fish, sometimes shellfish, amphibians, small mammals and young waterfowl.

Riparian forestA riparian forest or riparian woodland is a wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, sink or reservoir.
• Riparian forests help control sediment, reduce the damaging effects of flooding and help stabilizing stream banks.
• Riparian zones are zones between upland terrestrial land and water environment. Organisms found in this zone are adapted to periodic flooding. Many not only tolerate it, but need – it is important to their health and life. By Jakub
