The App "KraMobil" is now available! Visitors of the Zoo Vienna can spot crows with the app "KraMobil" and thus help to find out which species and subspecies of crows are living in the zoo and what behaviour they exhibit. Unfortunately Zoo Vienna is currently closed due to the Corona crisis, but we hope that this situation will change soon. The app is already available for download and can be tested by watching crows from the window. The project "Krähen im Zoo" is a cooperation of the Department of Behavioural and Cognitive Biology and the Core Facility Konrad Lorenz Research Center for Behaviour and Cognition of the University of Vienna with the Zoo Vienna.
