The 'Ringo Starr' of birds is now endangered: here’s how we can still save our drum-playing palm cockatoos

Australia’s largest parrot, the palm cockatoo, is justifiably famous as the only non-human animal to craft tools for sound. They create drumsticks to make a rhythmic beat.

Destroying vegetation along fences and roads could worsen our extinction crisis, yet the NSW government just allowed it

Many native species can all be found in vegetation along fences and roadsides outside formal conservation areas. And yet, the NSW government last week made it legal for rural landholders to clear vegetation on their properties, up to 25 metres from their property boundaries, without approval.
