What's the name of this bird? This morning I saw a bird that I have never seen before. Since it was quite big, I'm very interested in knowing its name. The bird was quite big, at least 2-3 times of a common blackbird. The wings were completely black but the whole back strip was quite yellow. Also the tail was yellow. The tail widens towards the end. The bird flew very strange... it trundled towards the ground and then flew back up some meters before trundling down again. I observed the bird in Zurich, Switzerland at the outer border of the city. A big forest is quite near and there are some huge trees very close to the bird. Then one last thing to add: I'm not really sure about that, but it could be that the bird had a nest on top of a big tree. Any ideas which bird that could be?

Following your answer to my comment, I deduced the “yellow” color to be more brownish as there is not big bird with really bright yellow color (like the golden oriole). With these parameters I search as well in the ornitho.ch database (all observations given by ornithologist professionals and amateurs) : there was no observation of vulture or eagle in that area (could be possible sometime when they migrate).

Then the more possible answer was a red kite which is quite common summer time in this area (mainly on the north part of Switzerland).

Next time you see a bird of prey, try to take notice of the tail form (forked or flat or round) that can help more for determining the bird.
