Plea to drivers as rare species makes return to Aussie island after 50 years

Plea to drivers as rare species makes return to Aussie island after 50 years

Yahoo2 days ago
Drivers have been warned they will likely be the difference between a native bird species surviving or not on a famous Australian island, after the species was recently reintroduced in an extensive conservation effort that still hangs in the balance.
For the first time in nearly 50 years, bush stone-curlew birds have been heard chirping on Victoria's Philip Island after scientists released a small number back in August, and again in April. Continued efforts are in place today with Australian National University PhD researcher Paula Wasiak, fellow researchers and volunteers, desperately trying to reintroduce and boost the population that was described as "functionally extinct" in the area.
The bush stone-curlew population suffered a drastic loss due to fox predation. However, after the island was declared fox-free in 2017 after 25 years of removal efforts, cars are now recognised as the "number one cause of mortality" to the birds, with several already being killed due to vehicle collisions in the last few months.
"We currently have 22 birds at the moment, but we have had some fatalities due to road strikes," Paula Wasiak told Yahoo News this week. "People need to be aware of wildlife on the roads, particularly at night. It's not just the curlews that are out and about. Slowing down can help hugely... there's a mix of roads with and without lights."
Driving behaviour can make all the difference, expert urges
Wasiak, who has been a Philip Island resident for 16 years, said driving behaviour will make the world of difference in their conservation efforts with the native birds. The initiative has been widely regarded a success with a 75 per cent survival rate. Vehicle collisions have accounted for the other 25 per cent.
"The birds we've introduced so far have been captive bred, so they may not respond how we may think a bird will respond to a vehicle," Wasiak explained. "They may not initially perceive a vehicle as a threat."

Simply slowing down on the road, reporting roadside sightings, or any road collisions, will make a huge difference in closing the gap between those birds that are thriving, and those being killed.
"We want to learn how they can live among us... We know how to introduce these birds within a fenced haven, but we now want to take this information and bring it to the urban environment of the island."
Success story hopes to pave way for more conservation efforts
The unfolding situation on Philip Island will hopefully pave the way for more conversation efforts of other dying native species.
"Bush stone-curlews are critically endangered," Wasiak stressed. "They're pretty much functionally extinct, so introducing these again will hopefully create a stronghold for the species."
She said the model they are using could be used for future reproduction efforts. "That's really the crux of it," she said. "We want to reintroduce so we can coexist with vulnerable species again.
"Making sure our cats remain on our property, making sure that we follow any sort of pet containment laws that keep our dogs on leads. That can really reduce the impact on our native wildlife."

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.

Motion cameras were set up in the jungles of Guatemala — and they captured something incredible

During a nasty summer heat wave — see: much of the US right now — water is a reliable source of relief. Where there are no rivers or lakes to swim in, we still might have swimming pools, sprinklers, and popsicles to keep ourselves cool. Wild animals don't have such luxuries. Bouts of extreme heat and drought — which are becoming more common and less predictable as global temperatures rise — can cause natural watering holes in many different types of ecosystems to dry up. And animals don't have a tap they can simply turn on. That leaves them with few places to hydrate and cool off, putting their lives, often already imperiled, at risk. But in some parts of the world, humans are offering help. In the jungles of northern Guatemala, which have been abnormally hot in recent years, environmental groups placed several large tubs of water in nature reserves. They refill them regularly, providing a reliable source of fresh water that animals can drink from or splash in, even when there's no rain. And luckily for us, they also put motion-activated cameras nearby to see which animals were using them. You might call them thirst traps. Courtesy of Wildlife Conservation Society 'The diversity of species using the water sources was amazing,' said Gabriela Ponce, head of Wildlife Conservation Society Guatemala, a group involved in the project with several others, including the local Guatemala NGO Foundation for Ecodevelopment and Conservation. The footage reveals a diverse cast of jungle characters, including those that are rarely seen, like jaguars and tapirs — large herbivores with distinct trunk-like noses. It also exposed some interesting animal behaviors, Ponce said. Researchers noticed that spider monkeys seemed to prefer drinking from raised water containers — perhaps so that they can quickly escape if predators approach, Ponce said. Wild animals are often more sensitive to environmental impacts than we are. They don't have technologies like air conditioning and water purification to survive all the ways in which we're altering the planet, from heating it up to filling it with pollution. And when climate disasters hit, the impacts are often devastating to wild animals, too. But there are simple ways to help wildlife cope with the world we've created for them, like putting out (clean) hummingbird feeders and bird baths or extinguishing invasive mosquitos that are spreading avian malaria. 'Artificial watering holes are not a permanent solution,' Rony García-Anleu, who leads biological research at Wildlife Conservation Society Guatemala, said in a press release. 'But they are a vital tool in helping wildlife adapt to increasingly unpredictable environmental conditions.' Solve the daily Crossword

A Biologist Spotlights The Most Abundant ‘Bird Of Prey' In The World. Hint: More Than 5 Million Exist, But You Won't Find Any In North America

Raptors, also known as 'birds of prey,' are not nearly as common as their less confrontational ... More cousins, like the sparrow, starling or swallow. Here's the raptor that you're most likely to find in the wild, assuming you don't live in the Americas. Generally speaking, there are three groups of raptors. One is 'accipitriformes.' These are diurnal (daytime) raptors and include hawks, eagles, kites, vultures and harriers. There's also 'strigiformes.' These are nocturnal (nighttime) raptors and include all species of owls. Then there's 'falconiformes.' This class comprises all falcon species – which, although also diurnal, are genetically distinct from eagles, hawks and the other accipitriformes. Some ornithologists might get fancier with their raptor classifications – possibly further subdividing these to highlight the evolutionary uniqueness of new world vultures, the secretarybird and the osprey – but the delineation above works as a general rule of thumb. Remember, what separates raptors from all other bird species is their carnivorous diet and hunting ability, including sharp talons, hooked beaks, keen eyesight and powerful flight muscles. However, these traits don't necessarily reflect shared ancestry. For example, falcons are more closely related to songbirds than to other raptor lineages. Of all of these raptor species, the most abundant is the black kite. Here's the story of the world's most common bird of prey. (Sidebar: Fascinated by remarkable birds? See here to meet the world's rarest eagle, and here to learn about the oldest known bird still alive today.) The Black Kite - The Most Common In A Class Of Rarities Black Kite (Milvus migrans). Abundant, adaptable, and widespread, the black kite (Milvus migrans) is a unique raptor. While many birds of prey are elusive, rare, or highly specialized, black kites thrive across a variety of environments, with an estimated population of more than 5 million individuals worldwide. That makes them the most numerous raptor on the planet. You won't find black kites in the Americas, however. Their range covers much of Europe, Asia, Africa and Australia. Black kites belong to the family Accipitridae, which also includes hawks, eagles, harriers and other kites. They inhabit a variety of environments, from open countryside and wetlands to urban areas. In cities, they are often seen soaring above garbage dumps, marketplaces and riverbanks, scavenging for scraps and small prey. This opportunistic feeding strategy sets black kites apart from more specialized raptors that rely primarily on hunting live prey. Their diet is famously varied: carrion, small mammals, insects, fish, reptiles and even stolen food from other birds. They are known for their intelligence and nimbleness, often stealing food mid-air from other birds, a behavior called kleptoparasitism. According to a 2008 study published in the Journal of Raptor Research, black kites at a landfill in Rome relied heavily on kleptoparasitism to get their meals – stealing food in more than 75% of observed feeding attempts. Most thefts targeted gulls, which were abundant and easy to rob, though kites also stole from each other. Researchers found that this strategy became more common and effective as kite numbers grew, especially later in the breeding season. Unlike many raptors that are solitary or live in pairs, black kites are often highly social. They congregate in large groups, especially at roosting sites where thousands may gather to rest overnight. These communal roosts provide safety in numbers and opportunities for social learning. During migration, black kites form large flocks, sometimes numbering in the thousands. These spectacles are a favorite among birdwatchers worldwide. Black kites share the hallmark raptor features that make birds of prey such efficient hunters. They have sharp, curved talons and hooked beaks designed for tearing flesh. Their eyesight is exceptionally keen, capable of spotting small prey or carrion from high in the air. Their long wings and forked tail give black kites exceptional maneuverability, allowing them to ride thermal currents for hours and conserve energy during long-distance travel. Thanks to their global abundance and wide distribution, they provide a valuable model for studying population structure and variation in migratory behavior across a broad geographic range. A black kite in flight. Some populations migrate thousands of kilometers between breeding and ... More wintering grounds, while others remain year-round residents. According to research published in Ethology Ecology & Evolution and the Journal of Avian Biology, their movement patterns vary across regions, with some Palearctic populations migrating long distances while others, particularly in India and Australia, remain year-round residents. GPS tracking has confirmed that individuals from northern Asia overwinter in South and Southeast Asia, while tropical populations tend to stay put. These regional differences are reflected in their genetics. DNA analyses show that populations from Europe, northern Asia, India, and Australia carry distinct haplogroups, suggesting historical separation and limited gene flow. A 2024 Zootaxa study found that Indian and Australian kites likely diverged at the end of the last Ice Age and no longer share haplotypes. Meanwhile, African populations, especially the yellow-billed kite, are genetically distinct enough that many researchers now consider them a separate species. Altogether, these findings point to a complex evolutionary history shaped by geography, climate shifts, and variable migration strategies. While many raptors face threats from habitat loss, pollution and persecution, the black kite has so far maintained stable populations across much of its range. Its ability to exploit human-altered landscapes has certainly helped. Their success story offers a striking contrast to the fate of many other raptors, which often decline in the face of urbanization. The black kite stands out as a reminder that adaptability is a powerful survival strategy. They may not be the rarest or most iconic raptor, but in terms of resilience, global reach, and sheer numbers, no other bird of prey comes close.
