Take a step back in time and relive your favorite moments from the nest box on the 2017 WBU Barred Owl cam!  Watch the owls deliver prey of all types as they work to raise three owlets to fledging.

The three eggs hatched on April 6, 8, and 10. The Barred Owls sole focus for the next 4–5 weeks will be to provide enough food and warmth to their owlets as they grow old enough to venture into the wild beyond the nest box.

*******************************
Jim Carpenter, President and CEO of Wild Birds Unlimited, has hosted a camera-equipped owl box in his wooded backyard since 1999. Set more than 30 feet high against the trunk of a pignut hickory tree, this Barred Owl box was first occupied in 2006. Since then, the box has hosted several nests, including successful attempts since 2013.

The camera system was updated in 2013 with an Axis P3364-LVE security camera and microphone mounted to the side of the box and connected to Jim’s house via 200 feet of ethernet cable. To keep predators like raccoons from investigating the nest, aluminum flashing was wrapped around the tree. An infrared illuminator in the box means you can keep track of the owls’ comings and goings throughout the night (don’t worry—the light is invisible to the owls).

Since the birds aren’t banded, we can’t tell whether this is the same pair as in past years. Although male and female Barred Owls look alike in their plumage, females can be up to a third bigger than males. You can also tell the difference between them by watching their behavior; only the female incubates the eggs and chicks, but the male is responsible for the bulk of the feeding, ferrying prey items to the incubating female, and sharing them with her inside and outside of the box.

For the second year in a row, the female laid her first egg on March 5; if all goes well, we can expect the owlets to start hatching between April 5 – 10. They’ll leave the nest four to five weeks after hatching.
