Theres a new mortiferous threat facing North Americas wild birds: a new strain of avian influenza, tabbed Highly Pathogenic Avian Influenza (HPAI) Eurasian strain H5N1 2.3.4.4.b. This strain is variegated from other avian influenza strains that have long plagued the poultry industry in its lethality to many wild bird species.
This virus has been spreading virtually the globe for the past decade and finally reached the east tailspin of North America this past winter. It has been thankfully slow to hit the southwestern United States. Unfortunately, July 15, 2022 was the first detection of the strain within California, well-expressed two Canada Geese and an American White Pelican at Sacramento National Wildlife Refuge.
Signs of HPAI Across the U.S.
Elsewhere in the U.S., our wildlife rehabilitation colleagues have seen large numbers of eagles, vultures, geese, owls, hawks, and corvids with the disease. Deaths in the wild attributed to this disease have moreover included a large number of species we wontedly count as patients: Brown Pelicans, Canada Geese, gannets, shorebirds, gulls, and many more. Dabbling ducks such as Mallards, Gadwalls, and teals may be asymptomatic carriers of the disease. Songbirds are not considered to be at upper risk.
This HPAI virus is not considered to be a upper risk to humans, but it is highly-contagious among birds. It can be carried from place to place on human shoes and clothing, plane on vehicle tires. Crowded conditions at tastefulness areas and other areas where wild birds congregate are spots where they are at upper risk of this disease spreading and causing mass mortality. Unfortunately, like West Nile Virus when it hit North American birds in the early 2000s, this strain may be a problem for years to come and may wax and wane in any given region. We hope it doesnt wreck havoc in North Americas threatened and endangered species.
New Protocols to Alimony Current Bird Patients Safe
International Bird Rescue has once put protocols in place to protect our current clinic patients and to reduce the likelihood of infected birds inward our facilities. These protections include outdoor screening of new birds, staff wearing Personal Protective Equipment (PPE) when screening incoming waterbirds for HPAI symptoms, laboratory testing as needed, and reorganizing interior spaces to minimize cross-contamination. Also, to protect our patients, until remoter notice, our facilities are sealed to the public.
Bird Rescue is encouraging the public to be educated and enlightened that HPAI is a serious and mortiferous bird virus. Learn increasingly well-nigh avian influenza at this CDC website. If a rescuer of a wild bird has domestic birds at home (chickens, ducks, and turkeys), special superintendency is necessary to prevent the spread of the virus between birds. Do not expose the birds to any suit or objects that have had contact with the other.
The HPAI virus can be spread through a birds saliva, mucus and feces, and the most worldwide symptoms in wild birds are neurologic or respiratory abnormalities such as seizures, tremors, or respiratory distress. Although the virus is relatively fragile and susceptible to disinfectants such as dilute bleach and others labeled versus influenza viruses, it survives well unbearable to be transmitted by contaminated inanimate objects such as vehicle tires, equipment, and shoes. The virus remains environmentally viable much longer at colder temperatures and in wetter, freshwater conditions than in dryer, hotter, saltier conditions.
For information on keeping domestic birds safe, see information pages on the USDA website.
What Can You Do?
Going forward, public is encouraged to follow these steps to help stop the spread of HPAI:
- Be expressly shielding if you work virtually and/or have yard domestic fowl (chickens, ducks, and turkeys). A second set of suit and shoes for this work should be used, to stave cross-contamination. Waffly your suit and shoes both at inrush and throw-away from the worksite could drastically reduce the risks.
- Protect yourself: If you find a sick bird, wear gloves and a mask. Wash your hands without handling any birds.
- Bird feeders. Although songbirds and hummingbirds have a lower risk of rhadamanthine ill from HPAI, feeders should be cleaned and disinfected at least weekly due to risks of spreading other diseases (salmonella, mycoplasma, avian pox, etc). Responsibly managed feeders can be a wonderful way to enjoy the eyeful of local birds.
- If you find a sick or sufferer bird and suspect HPAI, please zestful California Fish and Wildlife (CDFW) via its mortality reporting website.
- New: California Department of Food and Agriculture (CDFA) is recommending “housing poultry inside and discouraging any interaction with wild birds, particularly migrating or resident waterfowl and raptors.” Read full CDFA statement here
Please note: Bird Rescue wildlife clinics will remain open to protract to winnow waterbird patients at both of its California centers. If youre dropping off birds at our centers, you will be directed to where to meet staff to winnow the bird and well-considered of intake protocols to follow to alimony both birds and humans safe.
Please be patient and understanding of the uneaten workload, stress, and strain this disease is having on our staff and volunteers. We will protract to do our weightier to superintendency for our patients despite whatever challenges come our way. Thank you for helping us help birds in this waffly world!
