CDFW Provides Update on California Brown Pelican Stranding Event

Fri, 24 Jun 2022 16:42:06 GMT

Since approximately May 13, 2022, several Central and Southern California wildlife rehabilitation facilities from Monterey County south to San Diego County have admitted hundreds of sick California brown pelicans, a fully protected species in California.

The pelicans arrived emaciated, and some had secondary injuries or fractures. Almost 700 pelicans were admitted for rehabilitation during this stranding event. After rehabilitative care and careful monitoring, more than 130 of these pelicans have gained weight, demonstrated normal behaviors and have subsequently been released. Additional pelicans will be released in coming weeks. Pelicans that sustained injuries will require several more weeks of care before they can be released.

The California Department of Fish and Wildlife (CDFW), along with the U.S. Fish and Wildlife Service (USFWS), wildlife rehabilitation facilities and other state partners submitted carcasses for postmortem examination to determine the cause of mortality. Among the pelicans that were necropsied, the primary finding was emaciated body condition. No diseases or toxins were detected. Avian influenza was not detected in the examined pelicans. The cause of this stranding event was determined to be starvation. The factors that contributed to starvation are still under investigation.

Pelicans feed primarily on anchovies, but anchovies are currently abundant, and it is unclear why these pelicans were not able to find enough prey over this relatively short timeframe in May. It is possible the prolonged periods of unusually strong winds in late April and early May interfered with their ability to forage. Additionally, the overall population of pelicans has been increasing over the last several years, potentially leading to more competition for food resources. CDFW continues to compile information on the possible factors involved in this event.

Residents may report dead birds to CDFW’s Wildlife Health Laboratory using the mortality reporting form, which helps biologists monitor these events. If live birds in need of assistance are found, please contact your nearest wildlife rehabilitation center for advice.

Wildlife Scientists Continue to Seek Cause of California Brown Pelican Illness and Mortality

Since approximately May 13, 2022, several Southern and Central California wildlife rehabilitation facilities from San Luis Obispo County south to San Diego County have been admitting hundreds of California brown pelicans, a fully protected species in California. The pelicans have been found emaciated and frequently with secondary injuries or broken wings. Many of these birds died shortly after arrival at a facility. The California Department of Fish and Wildlife (CDFW), the U.S. Fish and Wildlife Service (USFWS), local wildlife rehabilitation facilities and other state partners are coordinating to assess the ongoing situation.

CDFW is conducting postmortem examination and testing on pelicans that have been brought into rehabilitation facilities. Results indicate that pelicans are succumbing to starvation-related problems. Currently, there are no indications of disease or unusual parasites. CDFW is unable to provide information on the underlying cause of this event at this time.

For your safety -- and that of the birds -- CDFW, USFWS and wildlife rehabilitation facilities ask the public to not touch, attempt to feed, or take photographs (“selfies”) with the birds. Please do not attempt to remove fishing lines or embedded fishing hooks from entangled birds as this may cause further injury.

Here’s how you can help

Report dead pelicans using the CDFW’s Wildlife Health Laboratory mortality reporting form to help monitor unusual mortality events. Please include photos if possible.
Support Wildlife Rehabilitation Facilities. Consider supporting one of the permitted facilities intaking brown pelicans and contact them directly for how to best assist.
Support the Coastal Ocean Mammal and Bird Education and Research Surveys (BeachCOMBERS) program. This collaborative project between Moss Landing Marine Laboratories, Monterey Bay National Marine Sanctuary, USFWS, CDFW and other partners enlists trained volunteers to monitor unusual mortality events.

California brown pelicans need your help! This species was listed as federally endangered under the Endangered Species Act in 1970 due to the impacts of DDT, a pesticide. After DDT was banned, they made a remarkable recovery and were removed from the endangered species list in 2009. This species plays an important role in the Pacific Coast ecosystem feeding on northern anchovy, Pacific sardine and mackerel.

CDFW, USFWS and partners will continue to track this unusual event. We value the public’s interest and appreciate all efforts to report.
