What is it about?
A spectrum of feeding of the eagle owl (Bubo bubo) was studied in the Republic of Mordovia. The results of analyzing the droplets o f the bird of prey to determine the specific composition of mammals are presented. Using this method, morethan half of all the registered kinds of rodents and insectivorous mammals were repealed. The most widespread food (55.3%) for the eagle owl in the conditions of Mordovia is Microtus arvalis. Rare species, which were not found earlier in the territories studied using traditional methods of catching, have been registered.

Why is it important?
About 64% of victims of the eagle owl were identified based on the bones of the skull and bottom jaw The importance of various skeleton elements in revealing the specific structure is noted. While using fine mammals for feeding, the percentage of bone remains in the droplets, as a rule, is less than that when feeding on birds.
