My short blog on London’s ring-necked parakeets has sparked some comment, particularly whether they are a menace to our indigenous birds.

Kate commented: “Unfortunately they take food and nest sites that native species like robins, blue tits and sparrows need.”

James said: “I have noticed a HUGE decline in small birds in the back garden since the arrival of the parakeets.”

To try and get beyond anecdotal evidence I turned to the RSPB to see what they had to say. Here’s what I learnt.

There are various reasons why parakeets do so well here:

• They originated in Lowland India and the foothills of the Himalayas, so obviously don’t mind a bit of a nip in the air.
• There is a plentiful supply of food for them in London from berries to bird-tables.
• Their breeding season starts very early; often in January so they have an enviable supply of nesting sites with little competition from our indigenous species some of which don’t lay eggs until June. They are hole-nesters in competition with owls, woodpeckers and starlings.

The RSPB is concerned about the interlopers’ effect on our native fauna, but are not currently calling for a cull. This may change as their population rises and their numbers need to be monitored.

Despite being incomers the ring-necked parakeet is protected under the Wildlife and Countryside Act, though it is illegal to release them into the wild.

So in short, it looks like the RSPB, along with most avian species, is sitting firmly on the fence when it comes to the Posh Pigeon. It also means I’ve probably not moved this debate on any further.

Blue Planet II

But here’s something animal related that is unequivocally good; Blue Planet II is currently the most watched programme of 2017. Yes, a show about animals presented by someone in his nineties has scored 14 million viewers. According to The Guardian newspaper this made it not only the most watched programme of this year but the third most watched of the past five years, behind only the football World Cup final in 2014 and last year’s Great British Bake Off final.

As the camera goes deeper towards the ocean floor, seven miles down last week as I recall, the animal life gets more and more strange and everything starts to look like a 1970s prog rock album cover.

Posh Pigeons, London Pests or Parrots, if you live in the capital you must have seen or at least heard these green screaming banshees. Not sure what I’m talking about? London is now home to thousands of ring-necked parakeets.

When out walking the dog I usually hear them first as they shriek from tree to tree, then catch a flash of green as they speed past. I don’t know if they’re just trying to warm up, but they seem to fly faster than indigenous birds. Their numbers are booming, but why? Could it be global warming? Whatever the reason there seem to be a plague of them about town.

So, I hear you asking where the hell did they come from? This is where the story gets a little murky. Some claim they are the descendants of birds that escaped from Isleworth Studios during the filming of the movie ‘The African Queen’ which starred Humphrey Bogart and Katharine Hepburn. But that was made in 1951, and I’m sure I never saw the little pests when I first moved to London.

Another bonkers theory is that Jimi Hendrix released a breeding pair during the 1968 Summer of Love.

A more likely explanation is that they are just escaped pets, which have somehow adapted to our rigorous climate.

Some would like to wring the necks of these ring-necked parakeets but not me; they don’t seem to bother other species and with winter on its way, they add a little tropical colour to our sometimes monochrome city.
