Garden bird feeders and water baths could be hotspots for infectious disease transmission.
Millions of Americans feed wild birds, especially in winter and spring. Studies show that this can influence birds' health and behavior in surprising ways.
Feeding wild birds is discouraged in Australia despite its popularity in other countries. But many Australians still put food out for the birds, and that's not a problem if it's the right food.
Is providing birds with food and water making them too dependent? Or are gardens just the new frontier of Australia's urban landscape? New research aims to find out.
