Is that a bird feeder he's sitting on? If it is full marks for ingenuity! How on earth did he get up there... great pic as well, I believe the key to a good animal portrait is keeping the eye sharp and it certainly looks it, good job.
Scurra, it is the bird feeder its sitting on, but what you can't tell from the shot is that the feeder is 5 feet above ground nailed to the top of my fence.
I started at my back door with my SLR and slowly moved forward, after about five minutes I was close enough that it took up the full view finder. After taking 15 shots on slr i switched to my Fujipix A303.
It was not bothered about my presence at all. The shot you see is from the A303 and I am so close I could grab the mouse without extending my arm. (I didn't btw! )
I was out in the snow in shorts, a vest and wellington boots... bloody freezing, but i couldn't pass up the opportunity to photograph it.
