This video from North America is called Barred Owl nest and youngsters fledging.
From the Cornell Lab of Ornithology in the USA:
Our Owls Are a Hoot!
With the launch of two new owl cams—the Barn Owl cam in Texas and the Wild Birds Unlimited Barred Owl cam in Indiana—the excitement is building. Early in the morning on April 8, the first of three Barred Owl eggs hatched revealing a downy owlet (watch the highlight). A second owlet hatched out on April 9, and the third appears to have hatched today. The Barn Owls‘ first egg appeared the same day the Barred Owls began hatching, and today they added a second! They’re expected to continue to add to their clutch over the next week.
