What is Semialtricial??
Most classifications come with refinements. Birds considered altricial but with slight differences are also labeled semialtricial. Semialtricial birds hatch with down-covered bodies but need to be fed and can't leave the nest. Owls are called semialtricial-2 since the babies are born with down but eyes closed.
Mrs B will remain with Boo for about 3 weeks, while the male Mr B. hunts and takes prey to the nest to feed both.. Boo's eyes will open at about 7 days old and Boo may be ready to leave the nest at or about 4 - 5 weeks of age, when the owlet will crawl out of the nest using the beak and talons to sit on adjoining branches (at this stage they are often referred to as "branchers"). Owlets start flying when they are six weeks old. The parents will continue to feed until the young reach independence at about 6 months old.
