The dazzling appearance of a peacock's tail is one of nature's great wonders.

Male peacocks will shake their brilliantly coloured long tail feathers to attract females in a courtship

display known as train rattling.

With its rattling sound and shimmering patterns of emerald and turquoise, the tail feathers appear to almost glow in

their own light.

And now the way in which these colours are produced could help us design the next generation of computer display screens.

Hi there, I'm Patrick Aye and welcome to 30 animals that made us smarter from the BBC World Service.

The podcast which reveals how animals like the Blue Muscle, Tardigrade and Desert Spider have been helping us solve some really challenging problems.

And thanks so much for all your biomimicry ideas. We've chosen some of them for a special live show which will be our final episode of the season,

which we've recorded with an audience and with some animals.

But please do keep sending us your ideas and if we get enough, we might even make another series.

So we look forward to hearing from you.

Okay, in this episode number 28 we'll hear how it's not only female peacocks that are

attracted to the male's dazzling display but scientists too as they look for ways of producing color that uses far less energy.

Just think about this for a moment. How many screens like reading tablets and phones do you have access to?

Now if you multiply that by how many people live on your street,

then your town, your country, and across the whole world,

well, just think about how much energy all that color costs to produce.

If, however, we could find alternative ways of producing colours like the peacock does,

we could make some serious energy savings.

I'm pretty sure that the first time I saw a peacock was in London when I was about 11 or 12 years old.

My uncle used to take us to an adventure fun house on the weekends.
