That's eeeeeeeeeh not eeeeeeeh necessarily true, now, Joe - unless a gaggle of them managed to escape Bono's Killiney compound. You see, I have seen said bird with my own two peepers, and it's a Peahen - not nearly as ornate but just as weird to see loitering about the roof of your new extension.

Let's start from the beginning(ish). It was Ali Hewson's 50th birthday not long ago - doesn't she look great, etc. etc - so Bono reportedly got her a load of Peacocks and Peahens for the garden. According to a recent newspaper article, one of them has gone AWOL. Thankfully my sister had read said article, so it wasn't a massively jarring surprise when her husband quietly nudged her to look out their bedroom window a week ago. Peering straight in at them was an extremely large white peahen.

So, the sister rang various pet rescues and bird sanctuaries, and there was a recurring answer: "That's nice, here's what you should feed it". She dutifully got some bird feed, so it looks like the beautiful beggar's hanging about in the short term. But what of the long term?

She rang Dalkey Garda Station, you know, just in case Bono called looking for it they could tell him it's hanging around the Springhill Park area. The Garda who answered laughed and said "Brilliant, maybe you'll get free concert tickets for the next couple of years!" She replied "that'd be super, but it's more about the welfare of the bird."

When the peahen isn't hanging around the roof of the sister's new extension, she can be seen trying to get comfortable on various windowsills, etc, in the Springhill Park area. She seems particularly fond of one large house near the entrance to the estate. The man who lives there has been a resident for over 30 years, is a keen bird enthusiast, and this is the first time he's ever encountered a peahen. When the sister informed him of the possible owner, he chirruped "Brilliant, maybe I can get my bin charges paid for the next couple of years!"

Yes, but what of the welfare of the bird? Well, nobody's called to pick her up yet, and this is beginning to irk some neighbours - according to Joe Duffy.

Joe.ie reports: "Some of the best lines from today's debate which included a peacock enthusiast telling Joe that he had "given up the cock" and sightings as far-flung as Cunningham Drive, Killiney, Dalkey and one neighbour's rooftop. One Liveline listener even told the host that last he had heard, Bono's prized peahen was being held hostage in Ballinclea Heights."

Here's the best bit: "Growing increasingly unhinged, Joe began playing a mash-up of peacock screeching with U2's classic 'Still Haven't Found What I'm Looking For' while callers began reciting their probably completely made-up sightings."

Yep, the bird is now that famous it warranted a 40 minute debate on RTE Radio 1's Liveline. Sadly, I missed the show - and the aforementioned mash-up - but the fellah rang in a flap (apologies) saying "They're talking about your sister's peahen on Liveline!" So the peahen is officially my sister's now, can't wait to tell her.
