Emu

Emu (Dromaius novaehollandiae) are endemic to Australia. There are feral populations around the world where it was the fashion to farm them in the 80s. When that ended in disaster as they churned up any soft ground, birds were, at times, released. On eBird, feral populations are shown in orange. 

They are found across Australia, perhaps surprisingly, except in the really dry and hot areas of the central west. Large and placid, they never strike you as being particularly intelligent although they do have sense enough to move away from humans. At times I have seen them running alongside my vehicle as they try to escape. 

Emu flock in small or large groups and are nomadic, moving through open country as they graze. Their plumage is a range of greys and often looks oily.  A bright orange/red eye stares out from a sometimes bald head and neck.
