OC releases HPAI fact sheet

The Ornithological Council has developed and released a new fact sheet on highly pathogenic avian influenza. The new fact sheet provides background on avian influenza and its effect on birds, precautions that ornithologists should take in the field, and information regarding reporting of possible infections and testing of dead birds.

As of mid-2024, the virus has been detected in wild birds everywhere except for Oceania. Since the first detection of current clade of HPAI H5N1 in the U.S., there have been documented effects on 171 species of wild and captive birds in 16 orders. The newest strain affects wild birds differently than previous strains, causing illness and death in a higher number of bird species, rapidly spreading within wild bird populations across a larger geographic region, and resulting in higher mortality rates in wild birds.
