Australian ‘trash parrots' develop unique drinking ritual seen for the first time
Source: CNN
Wild cockatoos in Sydney, Australia have developed a new way to drink water from twisted-handle water fountains. They use their feet to grip and turn the handle, then lower their body to keep it open.
The video shows the wild cockatoos standing in a queue, and waiting for their turn to have a drink, demonstrating surprising social behaviour. According to a study published on June 4 in the journal Biology Letters, this behaviour qualifies as a newly developed local tradition. The researchers say this skill is not accidental and reflects the cockatoos' intelligence and ability to adapt to urban environments in creative ways.
Clever cockatoos new learning to drink water from fountains
It's not yet clear why Cockatoos choose to drink water specifically from the fountain, despite other water sources also available. The cockatoos use both feet to manipulate the twist handle, then lowering their weight to turn the handle clockwise and keep it from springing back. Around 50% of all the cockatoos succeeded in drinking water from the fountain, after many trials.
The research team installed two motion-triggered cameras surrounding one drinking fountain with a rubber top with embedded spout, and a spring-loaded twist handle.
As they analyzed the video they observed that operating these water fountains is not easy to just stumble upon by accident.
Cockatoos local to Australia are intelligent birds, they can use tools, solve puzzles and play golf. In Sydney, these clever birds have figured out how to open trash bins, which is why locals call them 'trash parrots'. They even manage to outwit humans trying to deter them in what scientists describe as an 'innovation arms race'.
Know about cockatoos birds
Cockatoos are colorful birds with distinctive curved beaks and strong tongues, perfect for foraging for nuts, roots, and grubs. They're known for nesting in tree holes and gathering in loud flocks. Their playful, affectionate nature makes them popular pets, with some living over 50 years. The sulfur-crested cockatoo, with its bright yellow crest, is a favorite due to its striking appearance and charming personality.
However, their long lifespan and intelligence mean they require dedicated care and attention.
The highly social birds forage in flocks numbering from dozens to 100 and gather at night, often in trees near water. While the flock is feeding, a few birds guard in trees, keeping a watch to alert others with loud and noisy calls.
Researchers view about the Cockatoos
Alice Auersperg, cognitive biologist at the University of Veterinary Medicine Vienna in Austria who was not a part of the new study, told Live Science, 'Cockatoos have a playful curiosity'.
She added, "They are highly persistent in their object manipulation, and easily reinforced if a behaviour turns out to be rewarding'.
Another researcher of Western Sydney in 2018 came across the sulphur-crested cockatoos lined up to use a twisted handle watering fountain. 'When she reported this to the lab group, we all got very excited, and started planning how to best further study this unusual behaviour', study co-author Lucy Aplin, a cognitive ecologist at Australian National University shared with Live Science in an email.
Berenika Mioduszewska, animal cognition researcher at the University of Veterinary Medicine Vienna, shared with Live Science, 'I was not surprised to see that cockatoos in Sydney had learned how to use water fountains. These birds are highly curious and manipulative. If the design of a fountain incidentally allows for cockatoo manipulation, it may only be a matter of time before an inquisitive individual starts playing with it and discovers a new source of water'.
The research is a part of a larger project, 'Clever Cockie Project', which studies how behavioral flexibility could enable complex species like cockatoos to adapt in cities.
'The paper also highlights the importance of persistence and focus: longer attempts at the water fountains, and those made when fewer other cockatoos were present, were significantly more likely to succeed,' Mioduszewska said. He added, 'It offers a valuable lesson from the cockatoos- when mastering a skill, it is important to keep trying and to minimize distractions whenever possible'.

6,000-Year-Old Skeletons Have Distinctive DNA With No Link To Modern Humans
In a major archaeological breakthrough, scientists revealed that ancient human remains, unearthed in the Bogota Altiplano in central Colombia, do not match any indigenous human population in the region. The skeletons are 6,000 to 500 years old, and the study revealed that some of the individuals belonged to a previously unknown population. A team of researchers studied the genetic data of 21 individuals and published findings in the journal Science Advances in May. Earlier studies have revealed that two lineages existed - northern Native American and southern Native American. It developed when people started to move south after first arriving on the continent from Siberia. The southern Native American is further divided into at least three sub-lineages. However, scientists have yet to find the exact time and other details when the first people would have moved from Central America to South America. "We show that the hunter-gatherer population from the Altiplano dated to around 6000 yr B.P. lack the genetic ancestry related to the Clovis-associated Anzick-1 genome and to ancient California Channel Island individuals," the study noted. "The analysed Preceramic individuals from Colombia do not share distinct affinity with any ancient or modern-day population from Central and South America studied to date," the study added. "Colombia_Checua_6000BP can thus be modeled as a previously undescribed distinct lineage deriving from the radiation event that gave rise to multiple populations across South America during its initial settlement," it mentioned. The study author, Andrea Casas Vargas, a researcher at the Universidad Nacional de Colombia, told CNN on Wednesday (June 11) that the research team was "very surprised" with the findings. "We did not expect to find a lineage that had not been reported in other populations," Vargas added. Kim-Louise Krettek, lead author and a PhD student at the Senckenberg Center for Human Evolution in Germany, said, as quoted by Express UK, that this area is key to understanding "how the Americas were populated". "It was the land bridge between North and South America and the meeting point of three major cultural regions: Mesoamerica, Amazonia, and the Andes." Krettek added. The study is very important, Vargas said, adding that it is the first to sequence complete genomes in ancient samples from Colombia. Vargas said that the results raise questions "as to where they came from and why they disappeared. "We are not certain what happened at that time that caused their disappearance, whether it was due to environmental changes, or if they were replaced by other population groups," she said, further adding that more research will provide some answers, hopefully.

Visual Glitch Leads To Accidental Discovery Of Spiral In Mysterious Oort Cloud
Scientists have long assumed the Oort Cloud, one of the most mysterious structures in our solar system, to be spherical. But during the pre-production of their new space show, "Encounters in the Milky Way," they noticed a strange spiral pattern in the middle of the cloud. The show, which premiered on Monday at New York City's Hayden Planetarium, featured a computer-generated visualisation of the Oort Cloud on the dome. The team was reviewing the animation when they noticed what appeared to be a spiral structure inside the typically spherical cloud shape. It immediately attracted the attention of astronomers and animators, despite not being a part of the project and only happening by chance. The structure surprised the scientists as it looked like a spiral galaxy like ours. Jackie Faherty, an astrophysicist at the American Museum of Natural History and the curator of the show said, "We hit play on the scene, and immediately we saw it. It was just there. I was confused and thought that was super weird. I didn't know if it was an artefact; I didn't know if it was real," as per CNN. During the investigation, David Nesvorny, an institute scientist with the Southwest Research Institute in Boulder, Colorado, and the Oort Cloud expert said he initially thought the spiral pattern might just be a mistake in the animation. When he rechecked, he found the spiral was real and it wasn't just a glitch. He was surprised to know about this, as he had never noticed it before. Mr Nesvony published a scientific paper in April, "The Astrophysical Journal," saying, "Weird way to discover things... I should know my data better after years of working with it." He explained that the spiral shape in the Oort Cloud happened because of the galactic tide. Although the Sun's gravity controls everything in our solar system, the Oort Cloud is so far away from the Sun that its gravity becomes weaker and it starts to affect the objects there. So, instead of pulling them straight, it twists the way they orbit, giving it a spiral pattern look. The spiral pattern could help scientists better understand how solar systems form and evolve over time.
