Love birds and wetlands? You can help The Australian Nuclear Science and Technology Organisation (ANSTO) and the University of NSW (UNSW) with their citizen science project: the Feather Map of Australia.
The aim of the initiative is to understand and improve the health of wetlands and wetland birds across Australia by collecting feathers that have been dropped by birds. (Yes - you do need to leave any feathers ON birds attached to their owner!)
Feathers and other animal artefacts are often protected, however you can see all the details of the project, including where to send your collected feathers, on the Feather Map of Australia website.
