Some 3,000 tern eggs were abandoned at a Southern California nesting island after a drone crashed and scared off the birds, a newspaper reported in June.
In May, two drones were flown illegally over the Bolsa Chica Ecological Reserve in Huntington Beach, California. One of them went down in the wetlands, The Orange County Register, a local newspaper, reported.
Fearing an attack from a predator, several thousand terns abandoned their ground-based nests, reported the state’s Department of Fish and Wildlife.
Usually during June, the white birds would be watching their eggs as they begin to hatch. But now, the sand is filled with eggshells.

Melissa Loebl is the manager of the nature reserve. She called it one of the largest abandonment of eggs ever at the coastal area. The reserve is about 160 km north of San Diego, California.
Last year, the pandemic brought more and more people to outdoor spaces. In 2020, about 100,000 visitors came to the Bolsa Chica reserve. That is up from about 60,000 in 2019, she told the newspaper.
That has led to an increase in human activity, including flying drones, walking dogs, and riding bicycles. All these activities are not permitted.
Loebl said that there has been a great increase in dogs, particularly those permitted to run free. She explained that this is especially bad during the nesting season.
“The dogs chase the birds, and the birds abandon their nests,” she said.
Another problem is the development of multimillion-dollar homes near the reserve, said Fish and Wildlife guardian Nick Molsberry. While most residents respect the rules of the reserve, he said, some do not.
Some residents, suggested Molsberry, feel entitled and feel they “should be able to use the land as they like.” Officials, however, are increasing enforcement and fining people who break the rules.
The reserve is the largest saltwater marsh between Monterey Bay just south of San Francisco and the Tijuana River Estuary in Mexico. Some 800 species of plants and animals live at or migrate to Bolsa Chica.
