Observations of severely alopecic wolves in Białowieża National Park: a – camera trap image of the wolf found dead a day later (Table 1, C1 and Fig. 3); b – camera trap image from the camera positioned on a European bison carcass (Table 1, C4); c – photo taken by a Polish border guard on the border with Belarus on the bridge over the Narewka river (Kosy Most; 52.7996N, 23.8284E) near location of trap C2 (Table 1); d – photo taken by a forest ranger in the same midforest meadow as trap C1 (Table 1)

External inspection of a wolf carcass showing: a – advanced alopecia; hyperkeratosis; emaciation and severe dehydration and anaemia; b – presence of soil and fragments of vegetation in the mouth suggestive of some neurological symptoms, which were nevertheless ruled out by a negative rabies test result
