Undersized Emu's belligerence is just silly; but otherwise, she is perhaps the smartest emu of all. She is the only wild emu in 18 years to just sorta figure out the free food/tameness thing.
Take a step back: of course, we don't say 'bird brain' for nothing. Over the years, though, it's been interesting to see a few birds who can 'work things out' where others cannot.
The carport is a good example. Most of the 'home team' birds take some time to traverse the car port, but U.E. just wanders backwards and forwards without any concern.
