Avian Influenza Updates & Resources
(Updated February 25, 2025)
Highly Pathogenic Avian Influenza (HPAI) is a highly infectious disease of birds caused by type A strains of influenza virus. HPAI viruses can severely affect domestic and captive animals, wildlife, and is a potential deadly risk to human health. Avian influenza mainly occurs in birds and is spread naturally by wild birds. A second strain is spread through poultry. A third type is affecting dairy cattle and is related to bird strains. All these strains are also being detected in wild mammals and mammals living on dairy farms.
Outbreaks of HPAI have been a major cause of crane deaths in the past. It is estimated that over 10,000 Eurasian cranes were killed by the virus in Hungary in the winter of 2023. This is a tragic example of the potential for this virus to sicken wild birds, particularly cranes.
The International Crane Foundation continues to closely monitor the spread of HPAI. We take this issue very seriously. The health and wellbeing of both wild flocks and the cranes held at our Global Headquarters (Baraboo, Wis.) remains of the utmost importance to us, as well as our team. We employ a specialized full-time veterinary staff, which is prepared to take swift action to prevent and manage the spread of HPAI.
This page is intended to provide updates and resources regarding the current situation with Highly Pathogenic Avian Influenza (HPAI). This page will be updated intermittently. For the most current information, check with your state agriculture, natural resources, or public health agency (see State Agency Resources below).
It takes a flock! Our teams are hard at work to protect cranes in wild flocks around the globe, as well as those in human care. You can support this work by becoming a member or donating.
