Little Eagle and Australian Magpie.
This shot is in the latter part of an altercation that lasted only a couple of seconds.
I can't be absolutely sure about how it started as I only picked it up in my peripheral vision, but it seemed like the Little Eagle had been perched in a tree about 3m above ground and the Magpie swooped in and attacked, and the two tumbled to the ground.
I immediately swung around and got them in the viewfinder and managed to get 3 shots off before both had exited the scene.
Not an excellent example photographically, but an interesting record of the event...and another good example of how good Pentax's auto focus really is.
K-3 ii, DFA 150-450, handheld. See exif for shot details, where you will see the camera was set at -1.7EV, the result of previously attempting to shoot black birds.
Cheers,
Terry
