Dietary biology of the Eurasian eagle-owl own weight, and will kill the young of much larger species such as European otter ("Lutra lutra") and Eurasian badger ("Meles meles"). However, the single most widely reported carnivore is the red fox ("Vulpes vulpes"), as they’ve been recorded in the diet from Denmark and Spain to the Russian Far East. Many fox specimens taken by eagle-owls are young individuals or subadults. Some studies posited that the average fox taken as weighing about , about equal to the eagle-owl’s own weight, but another noted fox specimens killed that were estimated to weigh , much larger than the eagle-owls.

European land mammal age European land mammal age The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of European land mammals. These biozones cover most of the Neogene and Paleogene systems (i.e. rock layers which are 65.5 to 2.588 million years old). In cases when fossils of mammals are abundant, stratigraphers and paleontologists can use these biozones as a more practical regional alternative to the stages of the official ICS geologic timescale.
