Nice bird! But a bit problematic, of course.

I have set up a bird feeding house lately. I looks a bit odd, since its standing on the roof in front of my balcony. But I hope I can help the birds a bit, especially in the coming winter.
It looks very bad regarding the bird population here. I have not seen a single black bird anymore for 3 month or so. Also the other small birds a very rare now. Only some pidgeons and crows are still around , but also less than in the past.
And, surprisingly, the are a few birds of prey circling at times. Very big ones, perhaps even eagles - hard to say from the distance.
