I don't do a lot of birds, especially when I'm in the city, which is dominated by pigeons. :-( But get outside the city a bit and the variety of birds increases, although not always the size.
This is definitely the largest species I've seen around Kiev. My wife has often referred to them as Ibis, but the best I can tell, (which might not be all that good), this is a White Stork.
Some other time I'll post the original photo, but for now, here's a version I've played with a bit.
