There are many different types of owls in the world, and each one has its own unique abilities. Some owls are faster than others, but there is no definitive answer to the question of which owl is the fastest.
One of the fastest owls in the world is the Eurasian eagle-owl (Bubo bubo). This owl can reach speeds of up to 80 kilometers per hour when flying. Another fast owl is the great horned owl (Bubo virginianus), which can reach speeds of up to 60 kilometers per hour.
There are many other types of owls that are also fast flyers, but these two species are some of the quickest. So, while we cannot say definitively which owl is the fastest in the world, we can say that there are some very speedy owls out there!
