This is a young Kookaburra (called Dundee) fascinated by a R.A.F fighter jet that was flying past. It was the first time it had ever seen or heard a plane and fixated on it for about 2 minutes.
For those interested it was taken with a Nikon D50 with the Nikkor 70-300 f5.6 lens. The camera was set up on shutter prioity at 1/500. ISO 800.
