Say hello to D12 and D13. Those are the names of the eggs -- and perhaps the eaglets to come -- laid this week and last in the nest of the most watched eagle family on the planet.

Managed by the Raptor Resource Project in Decorah, Iowa, the camera poised above the next in a tree in Decorah has provided an intimate look at the daily life of a pair of eagles and their offspring. Last year, some 200 million people in more than 180 countries checked in on the eagles -- watched the eggs hatch, the constant delivery of rabbits, rodents and other prey, watched them fight and watched them fly.

Now, you can do it all over again. The birds are now sitting on two eggs that should hatch sometime in April.

This year the project has added a whole new element -- a tracking device on a young eagle that allows viewers to follow her where ever she flies. That, and much more information on eagles and on the web cams can be found at the Raptor Resource Project web site and blogs.
