I suspect the bird on the right is a young magpie but I am no expert...
"For whatever reason Tasmanian magpies don't swoop in the same way that mainland magpies swoop," BirdLife Tasmania ornithologist Eric Woehler said.
Dr Woehler said it was unclear whether it was to do with Tasmania not having as many magpies in urban areas like other parts of the country.
"Whether it's just simply that they are a bit more chill down here and a bit less stressed about people or that they don't breed close to people, which brings out this defence behaviour, we don't know," he said.
He said the few reports of swooping magpies in Tasmania were usually because a bird had been harassed.
how interesting! I have lots of maggies on the property and they don't swoop, so there must be something that triggers the behaviour and maybe the younger ones learn by seeing the older ones. what a study that would be!
