No, that’s not fly dirt on the picture — it’s the pair of wedge-tailed eagles who lord it over the upper skies here, and have done for the 30 years I’ve been here. They usually have a third in tow, their young one.
They cruise so high up it’s amazing they can spot anything down here on the ground. Their eyesight is equal to ours when using binoculars with 20 times magnification powers.
No other bird can make it up there, although the magpies will chase eagles a long way above the treeline.
I zoom in to check, but oh yes, it’s the wedgies.
