Footage showing a cassowary stalking a group of bushwalkers along a Far North Queensland walking track.

Senior wildlife officer Dinouk Perera, from the Department of Environment and Science, believes that the bird has probably become used to being fed by humans.

Mr Perera says Cassowaries are unpredictable, potentially dangerous animals and habituated birds have been known to act aggressively and lash out if they don't receive a feed when confronting people in the forest.
