Can't say I've seen one of those before!
Unfortunately, shutter speed is too slow - you've got some blurring there. The tail is also clipped off, so next time either decide if you want to make a picture from its head, or the whole body, if you choose the whole body back off a bit.
I know where I am today its been very dull, so I'd put the ISO up to allow for a faster shutter speed. Also what aperture did you have on this?
