There are thought to be only 85 pairs of these buntings left in the world - RSPB
The RSPB is to release predatory insects onto an island in order to protect the world's rarest bunting, in a new government-funded programme.
The Wilkins Bunting is one of the rarest birds in the world, found on Tristan da Cunha, a British Overseas Territory in the South Atlantic. There are thought to be only 85 pairs left.
Invasive bugs are to blame for their population's crash towards extinction; scale insects have been destroying the native Phylica trees, which the birds depend on for food.
Not only are they beautiful, but the colourful little birds on the island are important for the study of evolution, as they evolved much like Darwin's finches on the Galapagos.
The rarest, the golden Wilkins’ bunting, has a large beak evolved for eating the Phylica fruit.
To save the birds, scientists will be releasing predatory insects to eat the invasive species and prevent them from destroying more of the trees. Researchers are still studying which insects will be used, but ladybirds have been used before in similar projects.
The Department for Environment, Food and Rural Affairs has announced over £5m of environmental funding for the UK Overseas Territories, including a £600,000 grant to fund this project.
Head of the RSPB UK Overseas Territories unit Jonathan Hall said: “This Darwin funding announcement comes in the nick of time to save an incredible bird and an entire forest ecosystem from potentially disappearing forever. There is much work to be done, but we hope this vital grant may provide a lifeline to the islands’ extremely vulnerable wildlife."
Other wildlife to benefit from Defra's new fund include the British Virgin Islands’ turtle populations. They are funding education for local people on turtle conservation, and preserving and their reefs and seagrass meadow habitats.
Additionally, a number of species, such as Antarctic fur seals, albatross and penguin species including macaroni, king and Gentoo, in South Georgia and the South Sandwich Islands will be surveyed through drones to establish their baseline populations to help monitor and manage their long-term recovery .
International Environment Minister Lord Goldsmith said: “Through our Darwin Initiative and Darwin Plus programme, we are restoring many precious natural environments across the world, helping to transform the lives of the poorest communities and prevent the extinction of some of the world’s most wonderful species.”
Here’s what Russia’s 2020 disinformation operations look like, according to two experts on social media and propaganda. By DARREN LINVILL & PATRICK WARREN Internet trolls don’t troll. Not the professionals at least. Professional trolls don’t go on social media to antagonize liberals or belittle conservatives. They are not narrow minded, drunk or angry. They don’t lack basic English language skills. They certainly aren’t “somebody sitting on their bed that weighs 400 pounds,” as the president once put it. Your stereotypical trolls do exist on social media, but the amateurs aren’t a threat to Western democracy. Professional trolls, on the other hand, are the tip of the spear in the new digital, ideological battleground. To combat the threat they pose, we must first understand them — and take them seriously.

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term (Photo: Photos: Getty Images) Americans will almost certainly go to bed on Nov. 3 without knowing who won the presidential election. Since millions of people will vote by mail, constraints on time and resources will slow ballot counting into potentially a weeks-long process. Voting patterns suggest it’s likely that President Donald Trump could end Election Day in the lead in certain key states, only to be overtaken by Democratic opponent Joe Biden when more votes are tallied. This could create a nightmare scenario during the three months stretching from Election Day to the Jan. 20 inauguration: a battle on the state and congressional level over who is the legitimate winner. This could include Congress reconvening on Jan. 6, presided over by Vice President Mike Pence , with no consensus over its potential role in choosing the next president. This is arguably the most likely of th
Here is an interesting question in my list of philosophical questions: 1.) Should governments have penalties for those who live unhealthy lifestyles? A list of unhealthy lifestyles would include things like smoking, drinking, illegal drugs, prostitution, and other “vice” type activities. I guess the “government penalties” would be referring to monetary punishments, withholding medical treatments (insurance companies would love that), possibly imposing/regulating very high (exorbitant) prices on things considered unhealthy in order to cut down on their use, and other possibilities. 2.) Or, would you say that living an unhealthy lifestyle, likely resulting in a LOT of eventual personal pain and suffering, should be punishment enough for unhealthy lifestyles? When people make bad choices in life, often in their youth where ignorance and immediate gratification takes them over, 3.) Should a society be obligated to help "fix" them, by way of tax money? Is that part of
