Brush turkeys are often the last holdouts against gentrification. But they still face peril in urban environments and researchers are enlisting citizen scientists to understand how they can better survive

It’s hard not to look at the brush turkey as the avian archetype of the Aussie battler – persisting and thriving, even though the odds are stacked against it. These birds’ work ethic in the face of almost impossible living conditions, environmental hardship and sometimes outright hostility is truly something to behold.
