WBU Barred Owl Female Prepping for Breeding Season! Cornell Lab | Wild Birds Unlimited Feb 23, 2023

The Barred Owls at the WBU Barred Owl Cam in central Indiana have been busy over the last week or two, making nightly visits to the nestbox to rearrange the interior and get ready for another breeding season. We plan on launching the livestream as soon as the owls choose to lay an egg—hopefully we'll see that happen in the next week!

*******************************
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 2021 with a 1080p Axis P3375-LVE security camera 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.
