A eucalyptus tree in Burton Chace Park, Marina del Rey, became unstable due to strong winds, leading to a rescue operation for dozens of double-crested cormorant eggs. Earlier this month, park officials discovered 20 nests containing over 60 unhatched eggs and chicks in the tree, which had suffered a trunk split, causing a large branch to fall near a public walkway.
The Los Angeles County Department of Beaches and Harbors, along with the International Bird Rescue’s Los Angeles Wildlife Center, organized a team to ensure the safety of the eggs and chicks. On March 10, two wildlife biologists worked alongside the rescue crew to carefully relocate the vulnerable nests to a safer environment. After the successful operation, the eggs and chicks were transported to a wildlife center in San Pedro, while the damaged tree was cut down to prevent further risk.
Most of the nests held three to four eggs, with some already hatched. Double-crested cormorants typically build their nests in large groups and prefer elevated areas near water, as they primarily feed on fish. However, these birds often face criticism for the damage they cause to trees and local fish populations. In fact, cormorants have been linked to significant declines in fish numbers in places like Lake Huron.
Cormorants can consume about a pound of fish each day, which has raised concerns among local communities. Their droppings, which are highly acidic, can harm trees and other vegetation, and they often strip foliage for nesting materials.
During the incubation period, both parents take turns caring for the eggs, which usually lasts about a month. After hatching, it can take cormorant chicks five to six weeks to fly independently. They typically become fully independent around ten months of age.
The staff at the wildlife center are working diligently to care for the rescued chicks, with many expected to remain in care for up to three months. Once ready, the young cormorants will be released into established cormorant colonies, ensuring they have a chance to thrive in their natural habitat.
