Conservationists Release Rehabilitated Vultures Back Into The Wild On South African Mountain
The birds were set free on the Magaliesburg Mountains in northern South Africa, where there is an existing vulture colony. Vultures generally are not well-loved because of their appearance and because they feed entirely on carrion–or dead animal carcasses–and are often associated with death. But conservationists say these scavengers are critical for cleaning up ecosystems and preventing animal and human disease outbreaks. Because of their eating habits, vultures are also susceptible to mass poisoning when poachers target other animals, and they can die in their hundreds from a poisoned carcass. Six of Africa's other native vulture species are listed as endangered or critically endangered. The Cape Vulture was removed from the endangered list in 2021 after successful conservation efforts but is still classified as vulnerable. The vulture release was organized by Vulpro and the Humane World for Animals organization.

Scientists in South Africa Are Making Rhino Horns Radioactive to Fight Poaching
A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals but can be detected by customs agents. Under the collaborative project involving the University of the Witwatersrand, nuclear energy officials and conservationists, five rhinos were injected in what the university hopes will be the start of a mass injection of the declining rhino population. They're calling it the Rhisotope Project. Last year, about 20 rhinos at a sanctuary were injected with isotopes in trials that paved the way for Thursday's launch. The radioactive isotopes even at low levels can be recognized by radiation detectors at airports and borders, leading to the arrest of poachers and traffickers. Researchers at Witwatersrand's Radiation and Health Physics Unit say that tests conducted in the pilot study confirmed that the radioactive material was not harmful to the rhinos. 'We have demonstrated, beyond scientific doubt, that the process is completely safe for the animal and effective in making the horn detectable through international customs nuclear security systems,' said James Larkin, chief scientific officer at the Rhisotope Project. 'Even a single horn with significantly lower levels of radioactivity than what will be used in practice successfully triggered alarms in radiation detectors,' said Larkin. The tests also found that horns could be detected inside full 40-foot shipping containers, he said. The International Union for Conservation of Nature estimates that the global rhino population stood at around 500,000 at the beginning of the 20th century but has now declined to around 27,000 due to continued demand for rhino horns on the black market. South Africa has the largest population of rhinos with an estimated 16,000 but the country experiences high levels of poaching with about 500 rhinos killed for their horns every year. The university has urged private wildlife park owners and national conservation authorities to have their rhinos injected.

South Africa starts injecting rhino horns with radioactive material to curb poaching
A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals but which can be detected by customs agents. Under the collaborative project among University of the Witwatersrand nuclear energy officials and conservationists five rhinos were injected Thursday in what the university hopes will be the mass injection of the declining rhino population. Last year about 20 rhinos at a sanctuary were injected with isotopes as part of initial trials that paved the way for Thursday's launch. The radioactive isotopes even at low levels can be recognized by radiation detectors at airports and borders which can lead to the arrest of poachers and traffickers. Researchers at Witwatersrand's Radiation and Health Physics Unit say that tests conducted throughout the pilot study confirmed that the radioactive material was not harmful to the animals. 'We have demonstrated beyond scientific doubt that the process is completely safe for the animal and effective in making the horn detectable through international customs nuclear security systems,' said James Larkin chief scientific officer of the Rhisotope Project. 'Even a single horn with significantly lower levels of radioactivity than what will be used in practice successfully triggered alarms in radiation detectors,' said Larkin. The tests also confirmed that individual horns could be detected inside full 40-foot shipping containers,' he said.

World's smallest snake makes big comeback
WASHINGTON: A snake so small it could be mistaken for a worm has been spotted in Barbados, nearly two decades after it was thought to have been 'lost' to science. The Barbados threadsnake was found hiding under a rock in central Barbados during an ecological survey in March by the Barbados Ministry of the Environment and National Beautification and conservation group Re:wild. 'Barbados threadsnakes are blind snakes, so they're very cryptic,' said Connor Blades, a project officer with the Ministry of Environment in Barbados who helped make the finding, in a statement. 'They're quite rare also, it seems. There have only been a handful of confirmed sightings since 1889, so there are not many people who have ever seen it, unfortunately.' Measuring just three to four inches long when fully grown — tiny enough to almost fit on a US quarter coin — the Barbados threadsnake is the world's smallest species of snake. It is distinguished by orange stripes along its back, eyes on the sides of its head and a small scale on its snout. 'When you are so accustomed to looking for things and you don't see them, you are shocked when you actually find it,' said Justin Springer of Re:wild, who made the discovery alongside Blades. 'You can't believe it. That's how I felt. You don't want to get your hopes up too high.' The breakthrough came after more than a year of searching, as the pair upturned rocks trapped beneath a tree root. The tiny snake, which was found alongside an earthworm, was taken to the University of West Indies for careful examination under a microscope — it closely resembles the Brahminy blind snake, an invasive species, so the finding had to be validated — before it was returned to the forest. Only two percent of the Caribbean island's primary forest remains intact, with the rest cleared for agriculture since the start of the colonial era 400 years ago. The Barbados threadsnake remains particularly vulnerable since it reproduces sexually and females lay a clutch of only one egg. Female Brahminy blind snakes, by contrast, can produce fertile eggs without mating. 'The threadsnake's rediscovery is also a call to all of us as Barbadians that forests in Barbados are very special and need protection,' said Springer. 'Not just for the threadsnake, but for other species as well. For plants, animals and our heritage.'
