The endangered right whale that Georgia wildlife biologists once freed from fishing line caught around its midsection has returned off the coast four years later with a newborn calf in tow. Whale watchers at the state Department of Natural Resources are celebrating, saying it's the first time a whale saved from entanglement in Georgia waters has come back to give birth.
