Attractive birds more immune against bird flu

r forehead spots. The new study shows that males that are vaccinated against Newcastle virus produce more antibodies if they have large forehead spots.

"Thus it seems that the female uses the forehead spot as a health indicator. When she chooses males with a large forehead spots, she takes not only the healthiest males but also the ones with the best immune defence against future virus infections."

The study also shows that the male collared flycatcher can change the size of the forehead spot during the mating season and that males that unfurl their forehead spots most are those that produce the most antibodies.

The findings not only enhance our understanding of why animals behave and look the way they do but also help explain why animals that choose their own mates produce healthier offspring than animals whose mates are selected by humans.
