Common Redstart

When I was staring a bit out of my window,
I was suddenly on the alert by a very unusual bird.
He has a beautiful reddish-brown breast and a quickly moving, shivering reddish tail!
An amazing bird, white forehead, black around his face and throat, greyish feathers.

A common redstart, Phoenicurus phoenicurus, or gekraagde roodstaart.
At first, I thought I had never seen such a bird, but then I remembered years ago, I had one in my garden, back in 2010 (male), 2010 (female) and 2011, and even 2012.
