Barn Owl pellets, diet, and predator-prey relationships
In the course of a year, a breeding pair of Barn Owls needs roughly 4,000 prey items (4/night x 2 adults x 365 days + 4/night x average brood of 3.5 x 70 days) and there are lots of other predators that eat small mammals too. Because so many small mammals are being caught all the time you may think that small mammal populations are controlled by the amount of predation they suffer. In fact, the reverse is true. The predators are controlled by the prey!
