If you are travelling in the Balkans/Pannonian region, you may enter your birding lists in eBird.
The list of species entered so far is here: http://ebird.org/ebird/country/RS?yr=all
Many locations were added to eBird hotspots so it would be easier for you to decide what location to assign to your birding list. Right now some of the hotspots seem empty but that will change once more people start adding their lists.
List of currently existing hotspots is here. New ones may be added if you suggest so (try to keep your sites well-defined) :
http://ebird.org/ebird/country/RS/hotspots?yr=all&m=
(Regarding the crows, which seem to be one of the commonest birds here, our grey-and-black form should be entered as Corvus cornix, not Corvus corone as stated in some older field guides. The raven is Corvus corax, so be careful when adding your "corcor" entries. Swifts seen in northern areas are always Apus apus, not Apus pallidus, and Falco naumanni is a rare bird never seen in large cities.)
