Kate Brandis, an Australian researcher, has enlisted the public to help her track elusive waterfowl as the country’s wetlands disappear.

Instead of a letter inside, she found the feathers of an Australian white ibis. A day or so later, another envelope arrived, stuffed with more feathers. In the days following, more began to come.
