What do barn owls eat when they are born in captivity?

When barn owls are born and are still in the nest in captivity, they usually eat various rodent species offered by their parents or given to them by researchers. Barn owl parents or caregivers typically bring and offer small mammal prey such as mice, voles, and shrews to the owlets. These animals provide sufficient nutrition for the growing owlets and ensure they receive essential nutrients for healthy development.
