Emus are birds of the plains and are a fairly common sight from BrokenHill to Sturt NP. These ones showed no fear of me and approached me while I took photos of them. Emus are very primitive birds and this is reflected in their feathers which are a more for insulating them from the weather rather than anything to be used for flying. The feather barbs dont lock together like those on birds that can fly. If eagles had emu feathers they would never get off the ground.
