Wildlife Health Alert: Highly Pathogenic Avian Influenza Detections Continue in Portions of North Texas
February 18, 2026 – AUSTIN —Texas Parks and Wildlife Department (TPWD) urges caution as highly pathogenic avian influenza (HPAI) continues to circulate among wild birds in Amarillo and Lubbock.
Detected in all 50 states across the U.S. and Puerto Rico, HPAI is a highly contagious zoonotic virus (meaning that humans can catch the virus) that transmits easily among wild and domestic birds. It can spread directly between animals and indirectly through environmental contamination.
The congregation of waterfowl and other migratory birds around food, water sources and backyard flocks increases the potential spread of the disease.
The public can assist in interrupting HPAI transmission by limiting all unnecessary contact with wild birds. In areas that currently have a higher number of HPAI detections, TPWD discourages the public from feeding wildlife, which includes the use of bird feeders. Staff also recommends the hazing of wildlife away from food and water sources.
The public should take general precautions by not handling any sick or dead wildlife and by not allowing pets to interact with sick or dead wildlife. If a pet frequents areas with wildlife, they should make sure their pets are up to date on vaccinations.
If you encounter a wild animal with signs consistent with HPAI, contact your local TPWD wildlife biologist.
What is Avian Influenza:
Avian Influenza, caused by influenza type A viruses, is a contagious viral disease that poses a major threat to the poultry industry and animal health. Migratory waterfowl and other waterbirds are a natural reservoir for this disease as they congregate on wintering grounds
There are many strains of the virus that vary in severity based on the species affected. These strains are put into two general classifications— low pathogenic (LPAI) and highly pathogenic (HPAI). LPAI generally causes only minor illnesses and occurs naturally in migratory birds. HPAI spreads rapidly and has a high death rate in birds.
Additionally, select mammal species are highly susceptible to HPAI including domestic cats, skunks, foxes, raccoons, bobcats, mountain lions and black bears.
Due to the ease of transmission, TPWD recommends wildlife rehabilitators remain cautious when handling wild animals with clinical signs consistent with HPAI and quarantining animals to limit the potential for HPAI exposure to other animals within the facility. Backyard poultry may infect or be infected by contact with wild birds. If a wildlife rehabilitator suspects HPAI in an animal, contact TPWD within 24 hours of intake.
Clinical Signs and Transmission:
Clinical signs include neurological disease such as incoordination or stumbling, lethargy, trembling, seizures, lack of fear of people, coughing and sneezing and sudden death, though birds infected with HPAI may not always have outward signs of infection. The virus may spread in a variety of ways, including through contact with infected wild and domestic birds as well as by contaminated equipment, clothing and shoes of caretakers.
For mammals, transmission occurs primarily through the consumption of infected animal carcasses and contaminated equipment.
Currently, the transmission risk of avian influenza from infected birds to people remains low, but the public should take basic protective measures if contact with wild animals cannot be avoided. Public and health care professionals can find more information about HPAI in humans from the Texas Department of State Health Services. If you develop signs of illness after you have been in contact with an HPAI-positive animal or animal with clinical signs suspicious for HPAI immediately contact your healthcare provider and let them know about the exposure.
Prevention:
TPWD currently suggests discontinuing the use of bird feeders but if they are left up in areas with higher detections numbers then the bird feeders and water sources should be cleaned at least every two weeks with a solution of one part household bleach to nine parts water. Change water in birdbaths every few days and regularly remove wet feed and seed from feed and water sources.
