Radioactivity harms brightly colored birds
11 July 2007 - The University of Pierre and Marie Curie in Paris and the University of South Carolina jointly conducted a study investigating the radioactively contaminated environment around Chernobyl; scientists found that radiation is much more likely to have a harmful effect on birds with colorful plumage. The same applies to migratory birds and species that lay large eggs. What they all have in common is that they require particularly large amounts of antioxidants such as cartenoids. Radiation creates free radicals, which antioxidants help absorb. When a bird has low antioxidant levels, the likelihood of cell damage increases.
