Only the other day, a team of Brazilian scientists released a very interesting article, which says that the bill of Toco Toucan functions as a radiator to control the body temperature by controlling the amount of the blood flow to the veins in it.

I knew that their bill is hot in hot days and cold in cold days, and now I see why and how from the article. However, there may still be some secrets about the bill, and hopefully we'll unveil it some day.
