MARINE MAMMALS -- A newborn calf has been spotted among one of the pods of killer whales returning to the Puget Sound.

The Kitsap Sun reports the baby orca was seen Wednesday, when a majority of the three pods of killer whales returned to the San Juan Islands, as they do each year.

Ken Balcomb of the Center for Whale Research says all the adult orcas in the three pods seem to be accounted for, including one whale that had not been seen since February.

Balcomb says the newborn calf is male and still had his umbilical cord attached on Wednesday. That means he is only days old. His birth brings the total Puget Sound or Southern Resident orca population to 88. The whales are listed as endangered under the Endangered Species Act.
