For Delta and Dawn, the Golden Gate Bridge is getting closer all the time. The mother humpback whale and her calf have now passed under the Richmond San-Rafael Bridge and are making steady progress toward the Pacific Ocean, according to the U.S. Coast Guard.
The humpack duo is headed in the right direction to make it to the Pacific tonight if they keep up their current pace. Reported to be near Tiburon, the pair will have to navigate around that peninsula, which juts in their path. (Track the whales' progress on a Google hybrid map.)
The antibiotics that the whales received yesterday seem to have helped their skin injuries, so officials hoped to administer another dose today. The calf was beginning to act a little frisky, which is a good sign, according to marine biologists.
While everyone involved with the rescue effort hopes Delta and Dawn will make it out to sea tonight, there won't be any more measures taken to herd the humpbacks, according to officials. In the end, they say, it's all up to the whales.
