The gray whales are back, hugging the California coast while they make their 10,000-mile journey from Alaska to breed in the warm-water lagoons of Baja, Mexico, and back. In January, crew members on a whale-watching boat used a drone to record a baby gray whale and its mom off Salt Creek Beach in Dana Point.

Capt. Frank Brennan of Dana Wharf Whale Watching estimated that the calf spotted Jan. 7 was a day or so old, the Associated Press reported. “You could still see the fetal folds on it behind the blowhole,” he said. (You can watch video at bit.ly/babygraywhale.)
