Take a look at this little Blue Tit and admit that you have never seen a more pathetic picture of a bird that combines the colours blue, yellow, green, white, and black in the most marvellous way you have ever seen: Recent research has shown that Leonardo da Vinci showed a Blue Tit to his model while he painted the smile on “Mona Lisa&#.

Given the complexity of the research, the result feels like a bit of a letdown – “northern populations start migration earlier than southern populations, especially in autumn” The species name of the Chestnut-eared Bunting is fucata , from the Latin “fucare”, to paint red. Better safe than sorry.
