Food choices and possible explanation

Like the last few blogs, this blog uses information from the unpublished 1989 report "Conservation of the Ground Parrot in Western Australia".  Below are extracts from the 'Discussion' section. The low rainfall in the study area, to the north of the then Fitzgerald River National Park boundary, is a possible reason why the western Ground Parrot's diet contains much more green fruits and flowers than that of the eastern states birds.

High plant species richness could be a key to the survival of the Ground Parrot where rainfall is both low and variable.

The photos below are frames from videos taken in spring 2006, by Dr Brent Barrett and his team. The totally wild bird, nick-named Charlie, was in the FRNP not far from the study site of the 1988/89 project.
