I can see you!

This seems like a fine candidate for a caption competition. I can imagine the House Sparrow peering at the Coal Tit through the seed and saying "Oi! What you doing?".

Editing the RAW image, I upped the saturation a little as the original image was a little washed out. It is a noisy image - as are all of my images of late - as there wasn't much daylight to be had. It is also a shame that the Coal Tit's head was right in front of the black post.
