A timely reminder from the news item about the man being menaced by an adult bird.
These animals are either wild or have been fed previously and are therefore humanised to some extent. They also may be defending chicks. They have extremely powerful legs and the middle claw of their 3 toes is like a 12cm long dagger. Stand behind a tree, or reach your arms up to appear taller, if a bird is looking aggressive and you are nearby. Please remember this if you come across an injured bird or a cassowary in the rainforest and keep yourself safe.
