Pregnant elephant seal in Sonoma Co. moved to Point Reyes

SONOMA, Calif. (KGO) -- There was good news Tuesday night for the stubborn elephant seal who refused to leave a busy North Bay highway.

The massive mom-to-be was finally captured at the Sonoma mud flats near Highways 37 and 121 and was then moved to Chimney Rock at Point Reyes.

The 900-pound elephant seal was released in the dark in hopes of not disturbing the others on the protected beach. A male elephant seal, also called a bull, was heard lurking in the night.

"The big bulls are definitely a risk for us, they're dangerous to people, absolutely. They heard the noise. They heard the jostle. They wanted to know who it was. That was them trying to find out who was in their territory," said Laura Chapman of the Marine Mammal Center.

Earlier Tuesday, marine mammal experts spent a second day preventing the determined female elephant seal from crossing Highway 37 near the Highway 121 split.


"Elephant seals in general are stubborn. You usually have to use twice as much pressure, or a little bit of effort, more than other animals," said Barbie Halaska of the Marine Mammal Center.

She had already crawled out onto the highway the day before, causing a huge traffic jam.

"We were able push her back in the water, and we were hoping she would go back out with the tide last night. Unfortunately, she was still here in the morning," said Marine Mammal Center director of veterinary science Shawn Johnson.


Finally, the wayward elephant seal found a culvert. She swam down the creek, under Highway 37 and plopped down in the field she was trying to reach. Marine mammal experts quickly tranquilized her and performed an ultrasound.

"We did see a fetus, so she is pregnant. It will be great to get her back out where she can have her pup on the beach where she should," said Johnson.

Rescue workers named her Tolay after the creek she swam down. Tolay is now on the beach at Point Reyes where she can avoid the traffic and have her pup, where elephant seals have been breeding for more than 150 years.
