Falcon

I've tried to blip this fellow for quite a while now.

While he's sitting in tree he's almost invisible, and when I spot him, he's seen me first and is already gone. Seems hopeless...

Today I managed to catch his silhouette against the morning sun in the east. I'm quite sure this falconiform is a falcon, but I don't know which species. There are 6 different ones to choose from in Central Europe...

By the way: This is not a b/w pic. It's just a terribly grey day.

Have a lovely weekend!
