The powerfull river Inn seldom freezes over, so it is an important area for birds during moulting season, especially for ducks and other hibernating birds. At least 15 different kinds of ducks have been obsereved here, including sea ducks.
In springtime you can hear a fantastic concert of bird songs - from the islands and from the riverine forests. Voices include the oriole, the bluethroat, the marsh warbler, the river warbler, the penduline-tit and the Savi´s warbler.
Along stretches of flat water you will see great white egrets, little egrets and -with a bit of luck- the very rare black-crowned night heron. Depending on the season you can see a white-tailed eagle, black kites, marsh harriers and the osprey wheel in the sky.
The riverine forests and their adjustment meadows and fields are paradise to black-headed gulls, lapwings, curlews and the "flying gemstone", the Kingfisher.
