A pair of bald eagles is sharing the incubating duties for an egg in a nest in the Sequoyah National Wildlife Refuge near Vian, Oklahoma.
The Sutton Avian Research Center has a camera on the nest, allowing the world to watch the eagles raise another clutch of eggs.
Dan Reinking, senior biologist with the center, said it's common for bald eagle parents to take turns incubating their eggs.
The center has had a camera on this nest for years. Last year the camera failed just as the eaglets had hatched. Over the summer, at a time when the eagles weren't using the nest, the center replaced it with an upgraded model. The new camera includes an infrared feature, which allows eagle fans to watch the nest even at night.
