I finally caught up with it at 12 minutes past three and the sun had just dipped behind a large cloud. The light was just about passable although I had to use the fastest ISO speed possible. The good thing was it was settled on a post not far from the road, and I was able park along side without it getting disturbed.
The position of the post was useful as it was easy to drive back a bit, to get a good view from behind. From this angle the beak is almost completely hidden by the face feathers.
With their eyes pointing to the front owls have to turn their heads towards the object they're looking at. They have very large ears, not the feather tufts that give then their name, but large opening on the side of their heads. These are asymmetric and that enables them to know the direction and distance of any sounds they hear.
The last picture I took before it flew off hunting was at sixteen minutes passed three, so I been privileged to just under five minutes of it posing for me. I'm still hoping to bump into it earlier in the day, they do sometimes fly in early afternoon, but I think these were better than the last effort. I took a few more that can be seen here.
