The Eurasian Eagle Owl (Bubo bubo) is a species of horned owl resident in much of Europe and Asia.

The Eagle Owl is a very large and powerful bird, though despite its name it is much smaller than the Golden Eagle. It is the largest species of owl with a wingspan of up to 200 cm. Adults can weigh in excess of 4 kg, in comparison the common Barn Owl weighs about 500 g. It mainly feeds on small mammals but will take prey up to the size of foxes and young deer. It will also take many other birds including other birds of prey.

The calls of the Eagle Owl is a deep resonant “ooh-hu” with emphasis on the first syllable for the male, and a more high-pitched uh-Hu for the female. A recent study have shown that these calls are easily individualized. Thus we can identified all the individuals of an Eagle Owl population using their vocalizations .

The size, ear tufts and orange eyes make this a very distinctive species. It has a strong direct flight.

The horned owls are a part of the larger grouping of owls known as the typical owls, Strigidae, which contains most species of owl. The other grouping is the barn owls, Tytonidae.

The Eagle Owl is not naturally resident in England, but (ref. a BBC TV program) a pair have been breeding for several years in a valley in Ministry of Defence land in North Yorkshire. There is some debate as to whether these birds are escapees or whether they have arrived naturally from the continent which would only be a relatively short journey. At the time the program was made, they had reared 20 young to independence, and they had 3 young in the nest. Nothing was known of what happened to those 20 young, except that one of them electrocuted itself on power lines in south Wales.

The Eagle Owl's scientific name comes from its deep booming call. The word "bubo," based on the call, has referred to owls, particularly the Eagle Owl, since the dark ages, and is mentioned in Middle English bestiaries.
