CEDAR RAPIDS, Iowa (AP) -- The three Decorah eaglets that hatched this spring as millions watched online have left the nest. But one of them was fitted with a satellite transmitter that's allowed researchers to track its growth.

The Cedar Rapids Gazette reports that the eaglet, dubbed D-1 as Decorah's first satellite eagle, was fitted with a transmitter on July 12.

She stayed close to the nest, atop a tree at the Decorah Fish Hatchery, until Aug. 14. Then, Raptor Research Project director Bob Anderson says, the young eagle suddenly took off.

The project's nest-cam website was visited more than 206 million times this year as viewers worldwide watched the eaglets mature and leave the nest on June 16.
