DNA studies suggest that four fishing owls previously in the genus Ketupa, and the Snowy Owl, genus Nyctea are specialised horned owls and should be moved to Bubo.
The great hornedowls facial disk may have orangish or grayish feathers, and whiter feathers that form a V between the yellow eyes with fl pupils.
Great hornedowls tend to perch during the daylight hours in a protected rocky alcove or on a tree limb.
Great hornedowl eyes, which are almost as large as a humans, allows a great amount of light to pass through the pupil, so the owl can see in dark conditions.
The Great HornedOwl, Bubo virginianus, is a very large owl.
This is possible because owl ears are not placed in the same position on either side of their head: the right ear is typically set higher in the skull and at a slightly different angle.
By tilting or turning their head until the sound is the same in each ear the owl can pinpoint both the direction and precise distance to the source of a sound.
