Scientists at the Australian National University are studying the development of the double-wing in Australian bird species.  This evolutionary improvement can take various forms.  One theory is that since European settlement Australian birds have had to fly further due to land clearing.  Another theory is that something in the Australian environment has accelerated a natural evolutionary trend that will eventually be followed by birds elsewhere.  Of the below pictures, 3 are photographs taken in the field.  The fourth is drawn by an artist with the help of a description of a field observation.
