Location : Zagreb / Croatia, near the bank of Sava river.
I have been watching birds for many years using Collins guide but this time i can't find a help.
Bird was yesterday on the very top of cedar and attract me at first with specific song which i have never heard before, three times strong scream/whistle.
Back and wings faethers are greyish brown, front neck and undertail light greenish/yellow, dark pointed beak, blackbird size and shape.
It lasted short time so i can't use a camera only less than a minute by binoculars. Bird fly away on some nearest tree that i cant see her but stil can hear specific three times song.
Thank in advance for help or advice.

Hi, first off welcome to the forum on behalf of the staff and moderators. I can’t help with an ID, if the bird comes back hopefully you can get a photo. And I hope someone from your side of the pond will be along to help. I’m also going to add Zagreb to the title which might get more help.

Maybe female/juvenile golden oriole?

Thanks to all for hearty welcome and help to identify the bird. According to some web sources it is juvenile golden oriole. Fun fact : in croatian, oriole name is "vuga" and this is also croatian surname.
