How many years can an owl live?

It depends if the owl is in the wild or not. An owl in captivity could live well into their 20s and 30s, while a wild one would probably only live a few years, depending on the circumstances. Taking into account the size of the owl helps as well- a wild Elf Owl would live 3-6 years, while a wild Great Horned may live to be 13 years old.
