Feeling chirpy

 

 

Things males do to impress the females. Here’s the latest one to add to the list. Scientists have found that some birds, like the Zebra Finch for example, may merrily chirp away to themselves till they notice a female of the same species watching them. What happens next is incredible – realising that they have an audience, male finches will suddenly change their tune. And according to one study, the females much prefer the special songs created for them!
