There seemed to be a correlation between the many ravens along the Mount Kosciuszko trails and the movement of walkers. As scavengers it would seem reasonable to assume they do pick up the odd morsel here and there.
In Australia we have five species of the family
Corvus, two crows and three ravens. I am reasonably sure this is the 'Little Raven',
Corvus mellori.
This beautiful image of the strong downward thrust during flight highlights the airfoil structure in the wings while the upturned tips hint at the intensity of the beat as the raven flies close to the ground.
