The size, ear tufts and orange eyes make this a distinctive species. It has a strong direct flight. The difference between the male and female is that male's ear tufts are more upright than the female's. 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 largely nocturnal and is found in mountains and forests with cliffs and rocky areas, usually nesting on cliff ledges. They live for around 20 years although like many other bird species in captivity they can live much longer, perhaps up to 60 years. Although Eagle Owls are usually considered to be a bird of the great wilderness, they have been observed hunting vermin on open landfills in Northern Europe. This poses a certain risk for the owls as any pollutants the rats they feed on have ingested may be enriched in the owls. Eagle Owls that hunt on landfills have also sometimes been seen flying with waste entangled around their feet.
