Very nice website http://birdmap.5dvision.ee/EN/2016/autumn?line=1&track=0&speed=1 with near real life locations and tracks of 9 species. 

On the attached picture the stunning tracks of 7 Lesser Spotted Eagles. 

Their migration path is more than 8000 km's long and for the most part not wider than about 100 km's!
