Four out of five of Australia's black cockatoo species are now under threat nationally 💔 💔 💔 They are facing habitat loss from land clearing, competition from invasive species, declining food supplies, and bushfire-destroyed tree-hollows that they desperately need for safety and nesting. We are in urgent need of strong nature laws, to protect our most iconic species from extinction. Sign the petition: https://bit.ly/3eLeuDX | Australian Conservation Foundation
