Thousands of elegant tern eggs were abandoned recently after an errant drone crashed among their nesting field at the Bolsa Chica Ecological Reserve, frightening the birds away from their natural breeding ground.
The 1,300-acre coastal estuary is a premier birding location in Southern California sought by many populations of migratory birds, including numerous tern species. Bolsa Chica is home to the largest colony of elegant terns in the United States.
