A pair of barred owls have mated and established a nest several feet off the trail at Radnor Natural Area and Wildlife Refuge in Nashville. The nest is in a tree with a cavity about 30 feet from the ground in a shaded area. It’s difficult to see with the naked eye, but with telephoto lenses or binoculars you can see the opening and the owls moving in and out.
Several photographers (self-named “the Radnor paparazzi”) have been keeping watch. We must stay on the trail, so we peep from a distance, and now that spring foliage has blossomed, through leafy branches.
Mrs. Owl has been confined to the nest incubating the eggs until recently. I’ve read that female owls are the sole incubators. They develop a “brood patch” of sparsely covered skin in the breast area. This has a higher density of blood vessels for warming the eggs.
