WaldrApp is a Citizen Science project from the University of Vienna aiming to collect ecologic Information on the whereabouts of "Waldrapps" (English: northern bald ibis). Since these birds are an endangered species, the data collected through the app can help gain essential data for future settling projects. Feel free to join and contribute to this citizen observatory!

Citizen Scientists are spotting an endagered bird species

The northern bald ibis choose their feeding areas according to different characteristics: areas that are a long way away from roads, houses and trees and those with short vegetation are preferred. In addition, resource availability, as well as local loyalty and the formation of traditions play a role. With the help of interested citizens, this information should now be collected via the WaldrApp app.
