Come listen to the enchanting, haunting, sounds of wolves, coyotes, and dogs, and help us better to understand and conserve these species.

Analysing these recordings is difficult and time consuming. It's easy to make mistakes, and mistakes can change the conclusions that we draw. But here's where you can help! By having hundreds, even thousands, of volunteers giving their own analysis of the canid howls, we can investigate the role of these sounds, and understand more about the social behaviour of the whole range of canid species and breeds.
