Study reveals Gannets’ Irises Turn Black as a Result of Avian Flu Survival

A recent study has discovered that the irises of Northern Gannets change color from blue to black as a result of surviving avian flu. Northern Gannets are seabirds that breed on cliffs and islands in the North Atlantic. Scientists, who study these seabirds, have noticed that their irises turn black when they are sick or injured, but no one could determine why. After observing these birds for 15 years, a team of experts discovered that the cause lies in avian flu survival.

The discovery process

For over a decade, the team of scientists observed thousands of Gannets as part of a long-term research project. During this period, they noticed that the birds get sick every few years, and about two years ago, there was a particularly severe outbreak of avian flu that killed thousands of birds in Europe. However, they noticed that some birds emerged from the illness with black irises, while others recovered their normal blue eye color. This led the team to conduct further research.

What the study revealed

The study revealed that birds who survived avian flu developed dark patches around their eyes, which caused the irises to turn black. The blackness resulted from the accumulation of melanin in the iris as a protection mechanism against the virus. The researchers found that the pigmentation was permanent and the effects could even be seen in adult birds that had survived the virus as chicks.

Why this discovery matters

This discovery could have a significant impact on how avian flu is studied. It could also be used to detect sick birds in the wild. Currently, scientists have to rely on visible signs of illness, like malnourishment, ruffled feathers, labored breathing, and discharge from the eyes. The researchers say that the color change in Gannets’ irises could be a less invasive and more accessible way to tell if the bird is fighting a virus.

The conclusion

The discovery of the Gannets’ irises turning black as a result of avian flu survival is significant. Understanding this mechanism could lead to better ways of detecting and combating avian flu not only in seabirds but also in domestic birds. It is a remarkable example of how the animal kingdom can help us understand more about ourselves and the world around us.

Summary: Northern Gannets’ irises turn black when they survive avian flu, according to a recent study. This discovery could have a significant impact on how avian flu is studied and help detect sick birds in the wild.
