Learn why these diverse birds inspired Charles Darwin and how they're still informing evolutionary biologists today. Henk, I agree not all ash red spreads are lavender and I also agree it is incredibly variable but the ash red birds who remain almost completely unaffected by the spread gene are very rare from what I have seen.
