Great Horned Owl & owlet – Methuen Rookery

April 3, 2014 in Great Horned Owl

The Great Horned Owl pair in Methuen appear to have mated in early to middle of February. The female laid her egg in the middle of February, incubated it 30-35 days, keeping the incubation temperature constant, even during the all snowstorms. The owlet was born in the middle of March and will likely fledge in early June, at about 10 weeks. Owlets open their eyes at one week, and will start to leave the nest at four to five weeks of age. Owlets will then “branch” and then hang around on that branch for another 9 to 12 weeks when they become proficient at flying. The young stay near the parents until the fall, when they are forced to leave their parents territory.
