On the Trail of the Weasel

Who's in the Camera Box?

A joint initiative byUniversity of Zurich / ETH Zurich

Searching for Weasels With Camera Traps

Weasels are under increasing pressure in Switzerland. Their habitat is becoming smaller and observations of these elusive animals are becoming increasingly rare. As predators, however, weasels provide important information on the condition of the entire ecosystem. We therefore use camera traps to investigate the occurrence of weasels and their prey in the Swiss Midlands. Help us us evaluate these videos so that we can monitor their movements!

Help us to identify the filmed animals.

At various locations we have set up boxes equipped with a wildlife camera. The pictures give us an insight into the visitors of the box. In addition to weasels, numerous other species have visited the boxes. Help us to discover and identify these secret visitors!

Weasels in Switzerland

Anyone who has ever seen a weasel will never forget this observation. These elusive and clever animals fascinate people. But how are weasel populations in Switzerland doing? Did you know that there are two weasel species in Switzerland?

«I am very interested in the wildlife in our present cultural landscape. Therefore, I was tempted to make a contribution for the weasel project.»
