Endangered Sea Turtle Makes History Nesting on California Coast
First-ever documented olive ridley nest found in Orange County, with experts monitoring unusual behavior.
An endangered olive ridley sea turtle has laid eggs in two separate nests on the Orange County coast, marking the first time this species has been documented nesting on the U.S. West Coast. The nests were discovered in Seal Beach and Huntington Beach.
NOAA Fisheries is monitoring the situation, noting that the turtle's behavior has been unusual. "Typically, they do it during the night. This one has been a little abnormal in the fact she came up during the day and right as the sun was setting," said Justin Viezbicke of NOAA Fisheries, as reported by ABC 7. He added, "There is potential there could be other nests we do not know about."
The initial discovery occurred in Seal Beach when beachgoers reported what they believed to be an injured turtle. Lifeguards responded and found the animal was healthy and digging a nest. The same turtle was later observed in Huntington Beach, where it laid a second batch of eggs before returning to the ocean.
Olive ridley sea turtles typically nest much farther south, with their closest usual nesting grounds located near the southern tip of Baja California, Mexico. Scientists speculate that warming ocean waters, potentially linked to El Niño, may have influenced the turtle to travel hundreds of miles north of its typical range.
"This is our first ever documented case of a nest for an olive ridley turtle here on the West Coast," Viezbicke stated. "This is a highly endangered and protected species."
Both nesting sites have been secured with fencing and warning signs. Experts will maintain continuous monitoring of the nests throughout the incubation period, which typically lasts 45 to 60 days. Beachgoers are urged to maintain distance from the protected areas to ensure the eggs have the best chance of hatching.
Each nest is estimated to contain between 50 and 100 eggs. The success of hatching and the development of a new generation of olive ridleys will depend on several factors, including incubation temperature and the protection of the nesting sites.
