The great grey owl (Strix nebulosa) (also great gray owl in American English) is a true owl, and is the world's largest species of owl by length. It is distributed across the Northern Hemisphere , and it is the only species in the genus Strix found in both Eastern and Western Hemispheres.
Strix is a genus of owls in the typical owl family (Strigidae), one of the two generally accepted living families of owls, with the other being Tytonidae.Common names are earless owls or wood owls, though they are not the only owls without ear tufts, and "wood owl" is also used as a more generic name for forest-dwelling owls.
A likely event of predation by a barred owl on an adult great grey owl was observed. The authors hypothesized that the victim may have been a smaller male great grey owl (which can be about the same body mass as a large female barred) but this is the only known instance to date of a great gray owl being killed by another species of Strix owl.

Many people think that all owl species make a hooting sound, but that is an overgeneralization based on the call of this particular species. In addition, the double hoot, which many people think is the tawny owl’s prototypical call, is actually a call and response between a male and a female. [3] [4]
During the incubation period, the male feeds the female. These birds are monogamous, with biparental care. The young of most screech owls are altricial to semialtricial. [1] Northern screech owls are found in eastern states, such as New Jersey and New York. The screech owls are named for their piercing calls.
