With Avian Influenza circulating, here’s how to help protect birds

Highly Pathogenic Avian Influenza, known as HPAI, has landed in Southern California. HPAI affects both domestic and wild birds, and the threat of HPAI has caused serious concern. Pasadena Humane cares for both domestic and wild birds and has implemented biosecurity measures to prevent the bird flu from spreading at the shelter.

Sadly, you may have heard that Highly Pathogenic Avian Influenza, known as HPAI, has landed in Southern California. This extremely contagious flu with a high mortality rate has killed nearly 23 million birds in the United States since first being identified on the East Coast in January 2022.

A few weeks ago, our Animal Care and Control Officers were called out to a private pond where multiple geese had been found dead. Testing revealed the cause of death was HPAI, the first confirmed case of the pathogen in Pasadena.

Pasadena Humane’s health and wildlife teams have been carefully watching the migration of this deadly illness over the past year, while working closely with state and local health agencies in preparation for its arrival here.

HPAI affects both domestic and wild birds, and the threat of HPAI has caused serious concern. Pasadena Humane cares for both domestic birds, such as chickens and cockatiels, as well as wild birds like hawks, cormorants, and finches.

Dr. Maria Pyrdek, Pasadena Humane’s chief veterinarian, has been leading the way on biosecurity measures to prevent the bird flu from spreading at the shelter. Our Animal Care and Control officers now wear complete personal protective equipment when responding to bird calls to prevent contamination. All birds entering the shelter receive a physical exam to screen for signs of HPAI. Species most at risk — wild waterfowl and domestic chickens — are housed in separate areas and handled only by staff wearing full protective equipment.

Recently Dr. Pyrdek was asked to present Pasadena Humane’s HPAI protocols at the California Certified Wildlife Rehabilitation Conference to help other organizations identify potential weaknesses and better protect against the spread of HPAI.

Pasadena Humane continues to work closely with local public health departments, the California Department of Fish and Wildlife, and the California Department of Food and Agriculture to report and test any suspicious cases and share best practices in disease control.

Here are some ways you can help protect birds and control the spread of HPAI:

As the first line of defense against HPAI spreading at our shelter, we recommend that anyone who needs to rehome their pet bird first try home-to-home adoptions. And, for wild birds in need of assistance, contact our Wildlife Helpline at for expert guidance before touching the bird or bringing the bird to the shelter.

To reduce cross contamination in the community, remove bird feeders and bird baths. Feeders and baths encourage multiple species of birds to congregate together, making it easier for the disease to spread.

Keep cats indoors to prevent contact with infected birds. Walk your dog on a leash and avoid direct exposure to waterfowl and their feces.

Pet birds should be kept indoors and have no contact with other birds. Wash your hands thoroughly before and after handling your bird. If you notice any signs of illness, contact your veterinarian immediately.

If you own chickens, do not allow visitors into your chicken coop. Keep your birds in confined housing with a solid roof and walls, and wear dedicated clothing and shoes in the chicken’s housing areas.

For tracking purposes, report sick or dead birds to the appropriate state authorities. For domestic birds, contact the California Department of Food and Agriculture’s hotline at . Wild Birds should be reported to the California Department of Fish and Wildlife at or https://wildlife.ca.gov/Conservation/Laboratories/Wildlife-Health/Monitoring/Mortality-Report.

The Centers for Disease Control considers the transmission risk of avian influenza to people to be low, but as a general precaution the CDC recommends limiting contact with wild birds and sick or dead poultry.
