I often see nankeen kestrels hovering at the side of the road*. They must be the most abundant bird of prey in Australia. Getting a photo of one is another matter, as Duncan at Ben Cruachan blog can attest.
On my way back from North Queensland, I got stuck for a while at some road works. While I was waiting, a kestrel flew past the windscreen and landed on a fence post at the side of the road.
I scrabbled for the camera and got a couple of shots before the bird took off again. They're not the best photos because the camera's autofocus got the background in the first shot and the bashful bird turned away in the second. But ... y'know ... you take what you can get.
* They're the ones doing the hovering, not me.
