Standing at up to 1.9 metres tall, the flightless Emu is one of the world’s largest birds. One of the first birds to be discovered in Australia by Europeans, it was instantly recognised as an unusual species. One its unusual traits is its domestic life: after the female Emu lays her dozen or so green eggs, she leaves the male to incubate them on his own, and after they have hatched, the striped chicks are also looked after by the male, with no contribution from the female.
