AUSTRALIAN RAVEN

This is an Australian raven (Corvus coronoides), about 45 cm long and characterized by glossy black plumage and a pale white iris. These birds possess all-black glossy feathers with greyish bases hidden underneath. Distinctive white irises surrounding a dark pupil, indicate an adult bird. Strong, heavy black bill and perching posture typical of the Corvus genus.

Australian ravens are exceptionally intelligent birds. Like other corvids, they possess a high brain-to-body mass ratio and cognitive problem-solving abilities that closely rival primates and young children. They have been observed actively shaping and using sticks to extract insects buried deep within tree bark. In urban areas, Australian ravens work together collaboratively to pull heavy plastic liners out of public rubbish bins to access food. They are also famous for stalking bushwalkers and successfully unzipping backpacks to steal snacks.

They can accurately recognize individual human faces and categorize them as either a threat or a friend. They can hold these memories—and potential grudges—for several years. They easily pass vital safety information down through generations, effectively teaching their young which specific neighborhoods or humans are dangerous to approach.
