NOAA Fisheries announced a historic wildlife event along Southern California’s shoreline: a female olive ridley sea turtle has laid two nests in Orange County, the first documented West Coast nesting for this highly endangered and protected species.

First nest discovered at Seal Beach

Last week, wildlife cameras captured the turtle emerging on the beach at Seal Beach during daylight, an unusual behavior for a species that typically nests at night. The animal deposited an estimated 50 to 100 eggs before covering the nest. NOAA’s Justin Viezbicke called the find “our first‑ever documented case of a nest for an olive ridley turtle here on the West Coast,” emphasizing the rarity of the occurrence.

Second sighting at Huntington Beach

Later in the week, the same turtle – believed to be the same individual – was observed at Huntington Beach, again laying a clutch of eggs before returning to the ocean. Both sites have been cordoned off and warning signs posted to keep the public away and give the eggs the best chance of hatching.

Why this matters

Olive ridley turtles are listed as endangered, and their nesting habitats are limited primarily to tropical and subtropical regions. The daytime, sunset‑time nesting observed by Viezbicke is atypical, suggesting the turtle may be adapting to local conditions or that other, undiscovered nests could exist along the coast.

Temperature plays a crucial role in the incubation process, which lasts between 45 and 60 days. Warmer sands tend to produce more female hatchlings, while cooler sands yield more males, a factor that can influence future population balance.

Protective actions and public guidance

Local officials have placed protective barriers around each nest and posted signage urging beachgoers to stay clear. Disturbance can jeopardize the fragile eggs, reducing the already slim odds of successful hatching. The public is asked to respect these measures and report any additional turtle activity to NOAA or local wildlife agencies.

Looking ahead

While it may be weeks before hatchlings emerge, the discovery offers scientists a valuable opportunity to study olive ridley behavior on the West Coast and to assess the health of marine ecosystems in the region. Continued monitoring and community cooperation will be essential to protect this rare nesting event and to support the broader conservation of endangered sea turtles.
