The U.S. Fish and Wildlife Service’s Incident Command Team, in collaboration with partner agencies, continues to develop and implement conservation strategies to help California condors considering Highly Pathogenic Avian Influenza (HPAI). Early vaccine trial results available; birds from L.A. Zoo, San Diego Zoo Wildlife Alliance and Oregon Zoo participated in trial.
Birds from L.A. Zoo, San Diego Zoo Wildlife Alliance and Oregon Zoo participated in trial. Final analysis for the samples from Group 1 for condors are complete. USDA conducted hemagglutination inhibition tests on serum samples collected 42 days after the vaccination. The samples were evaluated for antibody titers that are commonly used as surrogate markers against influenza and other pathogens.
Group 1 received a vaccination of 0.5ml on two occasions (initial injection and booster). Results show that 60% of the condors had titers that are expected to provide partial protection against mortality, while 10% of those birds had titers expected to provide protection against mortality.

Black Vulture Vaccination Trial Results
No additional information since the last report. Titers (concentration of antibodies) present in the birds are still being evaluated by USDA’s Southeast Poultry Research Laboratory through refined testing methods to improve clarity in the results.
California Condor Vaccination Trial
Vaccination of condors in managed care began this week with three condors. The birds are doing well, and no adverse reactions have been observed during the evaluations on Wednesday and today, Friday July 21.
The trial will now continue with additional condors next week. Blood samples from the birds will be collected 21-days and 42-days following vaccination to evaluate the immune response from two different vaccination approaches. Group one will receive a vaccination of 0.5ml on two occasions, 21 days apart (initial injection and booster). Group two will receive a single vaccination of 1ml. A third group will serve as a control and receive no vaccinations, only blood sample collections. The administration of the vaccine in a single dose is being explored because it could streamline vaccinations in wild, free-flying birds if deemed appropriate. Trials will run into September.

Incident Update
The final blood samples from the black vulture trial were collected this week. Samples are being analyzed and results are pending. The Incident Command is continuing to prepare to implement vaccinations in condors in managed care. Vaccinations are expected to initiate in mid-July with the standard application of the vaccine - initial shot followed by a booster shot 21 days later - in three captive California condors to verify safety before proceeding with additional bird in the trial.
Ongoing Field Operations
The California Condor Recovery Program continue to implement standard operations and we are hopeful this will include the release of juveniles this year. However, due to the dynamic nature of HPAI outbreaks, and logistics around potential future vaccinations, adjustments will be made accordingly.

Incident Update
All vultures that received the HPAI vaccine as part of the initial trial on May 16 and June 5, appear to be in good health with no vaccine site reactions.
The preliminary antibody tests with blood samples collected in the black vultures 3 weeks after vaccination show that 2 individuals demonstrated clear positive titers to HPAI (commonly referred to antibody response) and several individuals indicated marginal antibody response. The second dose of the vaccine was administered the same day the samples were collected. Additional monitoring is necessary to determine the effectiveness of the vaccine in producing an antibody response which would be anticipated to demonstrate protection from the current HPAI virus.
Having demonstrated that the vaccine in the single and double dose application was safe in black vultures, the Incident Command is continuing to prepare to implement vaccinations in condors in managed care. Vaccination of condors will be administered by a state-licensed veterinarian at facilities with both state approval and a USDA-approved vaccination plan. Vaccinations are expected to commence with 3 captive California condors with a single dose to verify safety sometime after June 25.
Although the initial outbreak of HPAI in condors in Arizona appears to have ended, wildlife officials anticipate HPAI to spike during migration seasons and the potential for condors to be affected by the virus remains. As such, field monitoring across the population continues. The California Condor Recovery Program partners are continuing our standard management practices; and we are hopeful this will include the release of juveniles in the fall. However, due to the dynamic nature of HPAI outbreaks, adjustments will be made accordingly.
Carolina Raptor Center Director of Avian Operations Kristin Dean, holds a Black Vulture for North Carolina Department of Agriculture State Veterinarian Dr. Mike Martin, while U.S. Fish and Wildlife Service Veterinarian Dr. Samantha Gibbs draws up a dose of the HPAI vaccine. The vultures are serving as surrogates for the California condor to determine safety and assess the level of immunity induced by the vaccine.
On June 6, one of the cohorts of black vultures (10 of the 28 vultures) in the vaccine trial received their second dose of the HPAI vaccine at the Carolina Raptor Center, just outside of Charlotte, North Carolina. The other cohort of 10 vultures received a single double dose when the vaccines was initially administered on May 16. The remaining eight vultures are a control group and did not receive any vaccination. The two vaccinated cohorts will allow us to compare the effectiveness of the vaccine when administered through a single shot and through staggered shots. Blood samples were collected from all the black vultures in the trial at the same time as vaccinations. June 6 is 21 days after the first vaccine and is typically that amount of time needed to observe an immune response from the vaccine should it occur. Samples have been sent to the USDA’s Southeast Poultry Research Center for analysis. Since the vaccine has thus far been proven safe with the black vulture trials at the Carolina Raptor Center, the IC plans to move forward with vaccinating condors in managed care sometime after June 21.

The number of deceased condors and samples tested for HPAI in northern Arizona remain unchanged. Please refer to the update from April 17 below for additional information.
April 17, 2023
Free-flying California condors in Arizona continue to be confirmed with Highly Pathogenic Avian Influenza (HPAI). To be as transparent as possible to the public and stakeholders about the potential extent of this outbreak, until further notice, the Service will disclose and report all deceased condors in the Southwest Flock found on or after March 30, 2023, prior to necropsy and preliminary testing. As results are confirmed at the U.S. Department of Agriculture’s National Veterinary Service Laboratory, we will report them as "confirmed HPAI."
As of April 17, 2023, 20 condors have died in the Arizona-Utah flock; HPAI has been confirmed for 10 of those condors. Eight birds were captured and brought in for supportive care. Four of those condors died shortly thereafter and are included in the total of 20 deceased birds. Four condors are still receiving supportive care and have shown improvement. Learn more about HPAI.
Background
On April 7, Highly Pathogenic Avian Influenza (HPAI) was publicly confirmed as the cause of mortality for three California condors found in northern Arizona, according to wildlife officials. The Arizona-Utah population moves throughout northern Arizona and southern Utah, using the landscape within Grand Canyon National Park, Zion National Park, Vermillion Cliffs National Monument, the Kaibab Plateau, and surrounding areas. To date, the virus has not been detected in the other condor populations in California or Baja California, Mexico.
On March 9, The Peregrine Fund, which manages the Arizona-Utah condor flock, first observed a bird in the wild exhibiting signs of illness, initially suspected to be lead poisoning. Crews continued to monitor this bird and others showing similar behavior. On March 20, they collected a deceased female below her nest, which was the first bird confirmed positive with HPAI.
Upon collection, the bird was went to the U.S. Fish and Wildlife Service’s Clark R. Bavin National Fish and Wildlife Forensics Laboratory for necropsy to determine the cause of death. Oregon Veterinary Diagnostic Lab analyzed samples, and preliminary results indicated the bird tested positive for HPAI subtype H5N1. The positive result was confirmed by the U.S. Department of Agriculture’s National Veterinary Service Laboratory on March 30.
When initially reported by partners on April 4, a total of three deceased birds were confirmed as HPAI positive.
California condor populations face multiple stressors, such as exposure to lead shot and habitat degradation, that have reduced the resiliency of the population. To address the unfolding threat of HPAI, coordination is ongoing with avian influenza experts, veterinarians, and Tribal, state and federal partners across the condor’s range. California condor recovery partners are mobilizing resources and taking preemptive steps to protect wild birds from HPAI. Across the condor’s range, daily activities continue, such as captive breeding and the monitoring of breeding and nesting sites.
Potential exposure of HPAI is expected to rise during the spring migration of birds north to their breeding grounds. HPAI has been detected in all U.S. states, except Hawaii, in wild and domestic animals.
HPAI is considered low risk as a human health concern, according to the Centers for Disease Control; however, infections in humans have been reported. HPAI is highly contagious in wildlife and can spread quickly by several routes, including bird-to-bird contact, environmental contamination with fecal material, and via exposed clothing, shoes and vehicles. To protect people and birds, it is important to take precautions to prevent spread of the virus.
The Southwest Condor Working Group is supporting The Peregrine Fund and collaborating on monitoring condor health and behavior, identifying symptomatic birds, and transporting distressed birds to Liberty Wildlife, where they are receiving supportive care.
Ways to help
If you see a condor exhibiting any of the following signs of illness in Arizona or Utah, please contact The Peregrine Fund at (928) 352-8551 or condorprogram@peregrinefund.org. Signs include lethargy, incoordination, presenting as dull or unresponsive, holding head in an unusual position, and walking in circles.
If you see condors, please observe from a distance. Stress can be harmful to birds exhibiting symptoms of compromised health. Please be respectful and limit human disturbance when encountering these birds on public lands.
Report bird mortalities to your state wildlife management agency immediately so that bird die-offs can be investigated and tested for avian influenza: Report dead wild birds in Arizona call USDA 1-866-536-7593 and dead wild birds in Utah to local DWR office or call USDA 1-866-536-7593.
Please follow the below guidance to help limit the spread of the virus and avoid bird-human contact: To report dead or sick animals, please contact your state wildlife agency.
Keep your family, including pets, a safe distance away from wildlife.
Do not feed, handle or approach sick or dead animals or their droppings.
Always wash your hands after working or playing outside.
Prevent contact of domestic or captive birds with wild birds.
Leave young animals alone. Often, the parent animals are close by and will return for their young. For guidance on orphaned or injured wild birds, please contact your nearest wildlife rehabilitation center, state wildlife agency, or local land management agency.
