Context: A recent study by UNSW Sydney highlights the role of food theft, or “kleptoparasitism,” in the spread of the deadly H5N1 avian influenza among seabirds.
- This behavior, practiced by species like frigatebirds and skuas, involves forcing other birds to regurgitate prey, potentially transmitting the virus through saliva-coated food.
- Researchers found that this form of transmission could spread the virus across populations and regions, particularly during long migratory journeys.
- Seabirds are especially vulnerable due to their close contact in breeding colonies.
- Early detection is critical for preventing further spread, especially as the virus has not yet reached Australia.
