Fig. 2. Wildlife cameras revealed that the most common nest predator species were A) Eurasian magpie (photo by Niteforce Professional Trail Camera 12 MP), B) hooded crow (photo by Uovision UV595-Full HD 12MP) and C) raccoon dog (still from video by Uovision with +2 eyeglass lens). D) To adjust the focus of wildlife cameras into less than 1 meter, we attached +2 eyeglass lens (“backwards”) in front of the wildlife camera lens. Tape was then camouflaged.
