Clever Cockatoos Have Figured Out How to Drink From Water Fountains
In the city's western suburbs, some of the birds have figured out how to use public drinking fountains. The mohawked parrots deftly use one foot to twist the handle open while their other claw grips the spout.
It's unclear why the cockatoos go to the effort of using drinking fountains when there are plenty of accessible water sources nearby. They don't seem to use them more often during hot weather.
One possible explanation is that the task of operating the fountains is simply more fun than sipping water from the local creeks.
'If there is no super urgent need and you're not dying of thirst, then why not do something you enjoy?' said Barbara C. Klump, an author of a study of the birds published on Wednesday in the journal Biology Letters, and a behavioral ecologist at the Max Planck Institute of Animal Behavior in Germany.
It's not the first time cockatoos in this area of Australia have been seen cleverly manipulating urban objects for their own benefit. Dr. Klump and her colleagues have also tracked the birds flipping open garbage bins across greater Sydney, a socially learned behavior that has resulted in an arms race (or maybe a wing race) with human residents.

Australia's rat uprising: footage provides first evidence of native rakali attacking introduced black rat
An introduced black rat scratches through leaf litter, looking for food. Nearby, a native water rat watches on, its beady eyes shining. The native rat pounces out from the shadows, sending the invader fleeing. The encounter in Sydney bushland, captured on video, is the first documented evidence of an aggressive interaction in nature between a native water rat, also known as rakali, and a black rat. The footage, discussed in our new research, provides proof that rakali (Hydromys chrysogaster) actively hunt introduced black rats (Rattus rattus). This behaviour may offer a promising natural form of pest control. Rakali are carnivorous rodents, and the largest of Australia's 60 native rat species. Our findings suggest efforts to conserve the rakali should include Australia's urban environments, where introduced rats cause a host of problems. The problem of black rats Rats have lived with humans for about 4,000 years. In Australia, invasive rats are an ongoing concern. Anecdotal reports suggest Sydney, for example, has a growing vermin problem. Public concern was fuelled late last year when footage emerged of rats scurrying through a food court at a popular Sydney shopping centre (see video below). Black rats and brown rats are the two main pest rat species in Australia. Both were introduced by Europeans. They compete aggressively against other species for food and can breed quickly. Black rats are particularly abundant in urban areas and nearby bushland. They may prefer natural vegetation to urban environments, if there are no competitors around. Their ecological impact is significant. Black rats prey on bird nests, skinks and invertebrates and also eat seeds. Black rats also pose serious health risks to humans, pets and wildlife. They are the primary host of rat lungworm, a parasite on the rise in Australian cities. Rats also spread leptospirosis, a bacterial infection that has killed several dogs in Sydney in recent years, and infected scores of humans. Managing introduced rats is becoming increasingly difficult. Some rodenticides have become less effective as rats developed genetic resistance. And rat poisons have been known to harm native species. Clearly, better ways of managing introduced rats are needed. That's where our new paper comes in. Enter the rakali The rakali, or water rat, is found across much of Australia. It is semi-aquatic and usually lives near fresh or brackish (slightly salty) water such as creeks and estuaries. It is often described as Australia's 'otter'. The rakali weighs up to 1 kilogram – far greater than an adult black rat which typically weighs up to 200 grams. While surveying rakali around Sydney Harbour in June 2011, we captured footage of one lying in wait before ambushing a black rat. The observation took place in bushland on the foreshore of Sydney Harbour, near Collins Beach at North Head. We had set up a motion-sensing wildlife camera as part of a pilot study to understand relationships between rakali and black rats. At 10.22pm, the camera recorded a rakali next to a rock and hidden by vegetation. A black rat approached, and the rakali leapt out and chased it off. But do rakali kill black rats, or just chase them? Captive rakali have been known to kill and eat other rat species in captivity. And given the larger size and carnivorous diet of the rakali, they may in fact prey on black rats in the wild. Or rakali may reduce black rat numbers the same way dingoes reduce fox activity – by both preying on some and scaring others away. Our paper also canvasses growing evidence that native rodents can resist and suppress their invasive counterparts. For example, native bush rats (Rattus fuscipes) were presumed to be outcompeted by black rats. But an experiment at Jervis Bay in New South Wales removed black rats, allowing bush rats to reclaim their territory. After the experiment ended, black rats did not return. At North Head on Sydney Harbour, reintroducing bush rats to areas where they once lived led to a dramatic decline in black rat numbers. Recent research reported on footage captured in a Perth backyard of black rats attacking a native quenda, a small marsupial species found only in southwest Australia. However, the quenda appeared to fend off the attack. This means it's possible rakali, which are much larger than quenda, would be even more aggressive towards black rats. Native rats to the rescue? Evidence is growing that native rodents can help control pest rodents. This is especially true of rakali, which live in all major Australian cities where black rats are common. More research is needed to better understand the potential of rakali to manage invasive black rat populations. Troublingly, however, native rats are vulnerable to rodenticides. To support their role in pest management, the use of poisons to control pest rats should be reconsidered. By allowing native rodents to thrive, we may be able to harness their natural behaviours to control invasive pests safely, sustainably and effectively.

Woolworths investigating after shopper notices issue with popular product
A Woolworths customer is urging other shoppers to 'avoid getting ripped off' by doing one simple task when selecting their items. He's encouraging fellow Aussies to make sure they're getting what they pay for, especially when it comes to some of the more expensive items. Queensland man Ben was checking the weights of the 180g containers of roasted and salted cashews, and took three packets over to the scales in the produce section to see how closely they matched the labelled weight. 'You want to make sure you get what you pay for,' he said. Despite being identical, he found that each of the three packs had a different weight, with one weighing almost 20 per cent less than the heaviest. The discrepancy has caught the attention of Woolworths, who told Yahoo News they are now investigating the issue. While his TikTok video claims that the weights ranged from 145g to 180g, many viewers were quick to point out an issue with the scale. A message on the screen says that it needs to be zeroed, with a measurement under the plate reading negative 35g. This would make the weights of the products between 180g - 215g, which would more accurately count for both the nuts and the packaging. A Yahoo experiment compared the weights of six packets of the same cashews on a correctly working scale inside Woolworths on Monday, and found all six to weigh between 200g and 210g. But did Ben's results still highlight a problem with the products? Woolworths investigating varying weights It can be easy to discredit the video because of the inaccurate weights, but the 35g discrepancy between the products is actually not acceptable in Australian packaging standards. A close look at the container could explain minor fluctuations, with the letter 'e' written beside the 180g weight. The 'e' is a commonly used symbol also known as the estimated sign or the quantité estimée. It can be found on a range of other prepackaged goods, including fruit and vegetables, cereals, snack foods, cheese and meat. In Australia, the 'e' indicates goods have been packed in accordance with the Average Quantity System (AQS), but there are limits to how much the weight can vary. For items between 100g and 200g — like the cashews — an acceptable tolerance is 4.5 per cent of its weight, meaning they can only fluctuate by 8.1g. The heavier the product is, the smaller the margin for error is. 'AQS is based on recommendations developed by the International Organisation of Legal Metrology, and is intended for use in large-scale packaging plants where goods are packed in the same quantity in batches of at least 100 packages,' a spokesman for the National Measurement Institute previously told Yahoo News Australia. He added the AQS helps manufacturers and packers with export, as other countries also use the 'e-mark', and gives international buyers confidence in the quantity presented on the product. Woolworths told Yahoo News that based on the varying weights in Ben's video, they have launched an investigation with their suppliers. "All of our products are expected to meet their weight standard, and we and our suppliers have relevant checks in place on this front," the spokesperson said. "Given what we've seen in this case, we're already working with our supply partner to investigate. "If a customer is ever concerned about the weight of a product, we'd encourage them to take the item to the Service Desk in store. We then have the product details and batch numbers we need to investigate further." Do you have a story tip?

Joan Anderson, Unsung Heroine of Hula Hoop History, Dies at 101
In 1956, Joan Anderson, a Los Angeles housewife and onetime model, flew to Australia, her home country, to visit her parents. When she arrived, she realized that a curious fitness craze had taken hold. 'Everywhere I would go, everybody was giggling,' Ms. Anderson said in 'Hula Girl,' a 2018 documentary. 'I asked what was going on and they said, 'Oh, everyone's doing the hoop.'' The 'hoop,' she discovered, was an exercise ring, made of wood, that was swiveled around the waist and hips. 'Everyone was having such fun,' she added, 'I thought, 'I'd like to do that, too.'' Back in Los Angeles, Ms. Anderson asked her mother to mail her one of the rings from Australia, and it soon brought joy to the Anderson household. Her children played with it. Ms. Anderson swerved it around her hips for friends at dinner parties. When someone told her that it looked as if she was 'doing the hula,' the traditional Hawaiian dance, Ms. Anderson was struck with inspiration. She named the object the hula hoop. What transpired next would place Ms. Anderson at the center of what she described as an American tale of shattered dreams and promises, a business deal made on a handshake, and, eventually, a lawsuit.
