We have very large flocks of galahs, a parrot about the size of a large pidgeon, and they often sit on roads in country areas where grain or feed trucks have spilled food. Any decent person slows right down, but occasionally you see where some feral has just ploughed through a flock killing dozens of them. Makes me sick of humanity sometimes. Swans are protected in the UK because they were reserved for the table of the King/Queen. Any commoner nicking one went straight to gaol.
