Roos, and emus as dumb as politicians
Roo stands perfectly still until you are level, then jumps as your nose passes and ends up trying to come in through the rear door. Don't ask how I know this .
Emus are as stupid as roos, and exhibit the same behaviours as bep describes above.
I have also almost collected an eagle the size of a large child, feasting on roo carcass courtesy of an earlier truck, decides to take off before I get to him and has not compensated for the n many kilos heavier it is . Its talons left a small chip just above the windshield.
