No two drummers are ever the same in the world of Woodpeckers - we discover their sophisticated art of rolls, strokes and rhythms. Professor Josep Call from the University of St. Andrews tells us about Wikie the talking Whale. And Terry Flanagan reports on some frisky swan activity on Lough Ennell... Your panel tonight: Richard Collins, Eanna ni Lamhna and Niall Hatch...
We know that many birds make specific calls or songs which allow them to identify individuals, and separate them from others nearby - for example, female zebra finches can identify their mates, and king penguin chicks can pick out their parents amid thousands of birds in a colony.

Now, new research shows that great spotted woodpeckers communicate with "talking drums", which can identify individual birds from others in the locality. Researchers in Poland recorded the sounds of 41 woodpeckers drumming against dead tree trunks and branches. To tell us more, we're joined in studio by our panel of Niall Hatch, Development Officer with BirdWatch Ireland, zoologist Dr. Richard Collins and entomologist Eanna ni Lamhna...

If someone asked you what separates humans from other animals, one of the first things that would probably come to mind is language. It is so fundamental to human life that it's hard to imagine what life would be like without it. Our vocal cords can of course produce a large number of sounds, and tens of thousands of distinct words. Animals and birds have entirely different biological structures, which impact the way they form sounds.
Talking birds can mimic the spoken language of humans. But a new experiment has shown that something else can join the short list of creatures capable to mimicking human speech, and the implications are far-reaching.
Wikie the Killer Whale, lives in an aquarium in southern France, and has been taught to copy human words through her blowhole. Josep Call is Professor in Evolutionary Origins of Mind at the University of St Andrews in Scotland, and a co-author of the study; he joins us this evening from the University to tell us more...

About 15,000 Whooper swans overwinter in Ireland every year. Having spent the summer in Iceland they make the journey south in October to see out the winter months here. One of our most important sites for Whoopers is Lough Ennell in Co Westmeath, which is a well known haven for all kinds of birds, from waders to wildfowl, and the native Mute swan is present there all year round.

Earlier this week Terry Flanagan headed off to the "Lakes County", as Co. Westmeath is known, and met up with Derry Kilroy, who lives on the edge of the lake and who has been keeping a close eye on ALL the swans there...
If you'd like to learn more about the Whooper Swan, why not listen back to this Mooney Goes Wild documentary: The Whooper Swan - From Iceland To Ireland. Professor John O'Halloran is an ornithologist at UCC. In this documentary, John focuses on the Whooper swan, which is one of three species of swan that occur in Ireland along with the Mute Swan and the Bewick's swan. The documentary was produced by Derek Mooney. Click here to download The Whooper Swan - From Iceland To Ireland.
