BOULDER, Colo. -- An owl family of four has moved into a nest in front of a camera in Boulder.

The two adult Great Horned Owls and their two babies are nesting in front of a Web cam that can be seen live on the internet.

The camera is at the National Center for Atmospheric Research (NCAR) in Boulder, and its staff has apparently named the two Great Horned Owls "Harold" and "Maude."

The owls have taken over a nest that was used by ravens last year.

On its Web site, NCAR said the ravens "have not been pleased with their living situation, occasionally circling the area, trying to reoccupy their home. The two owls are unconcerned with the ravens' menacing behavior, and fiercely defend their 'new' nest."

Wikipedia's Web site said Great Horned Owls live in both North America and South America. The birds are found in forests, tropical rainforests, prairie, mountainous areas, deserts, subarctic tundra, rocky coasts, mangrove swamps, and some urban areas.

Great Horned Owls are considered some of the earliest-breeding birds in North America. They breed in late January or early February through April.

To see the nest and hopefully a glimpse of the owlets, visit NCAR's Web site. The image is updated every three seconds.

Xcel Energy also has several bird cams on its Web site. The cameras are set up on nests at Xcel Energy power plants.
