This video says about itself:
Great Horned Owl (Bubo virginianus) calling for its mate on Dixon Branch of White Rock Creek in Dallas, Texas. This particular owl was hooting a territorial call for another owl that can be faintly heard some distance away beginning after the call around the 1:50 mark. The owls call to each other in a duet before finding each other for night hunting and nest building.
From the Cornell Lab of Ornithology in the USA:
This cam was initially planned to broadcast from an established Bald Eagle nest nearly 80 feet above the coastal Georgia salt marshes. But last month a pair of Great Horned Owls moved into the nest instead. So, we’ll go with the owls.
Right now the female is incubating two eggs, which should hatch around the end of January. Don’t miss your chance to get to know these secretive denizens of the darkness as they raise owlets in the coming weeks.
