PLANNING TO VISIT?
The Urban Birder, David Lindo, (theurbanbirderworld.com/ tours) runs owl-spotting tours to northern Serbia in December, led by himself and Milan Ruzic. The 2018 tour costs £1,200, plus flights via Belgrade. Spring tours to Serbia are also available, but these will have a different focus.
There are many other interesting birdwatching tours in Serbia that are offered by Birdwatch Serbia, whose website also offers useful information about the country: birdwatchserbia.rs
