Wild chimpanzees recorded waging ‘civil war’ with coordinated attacks between two groups

New study describes what may be the first case of a unified community of chimps, in Uganda, turning on itself

On a June day in 2015, primatologist Aaron Sandel was quietly observing a small cluster of the Ngogo chimpanzee group in Uganda’s Kibale national park when he noticed something strange. As other members of the chimpanzees’ wider group moved closer through the forest, the chimpanzees in front of him began to display nervous behaviour. They grimaced and touched each other for reassurance, acting more like they were about to meet strangers than close companions.

In hindsight, Sandel said, that moment was the first sign of what would become a years-long bloody conflict between a once close-knit group of chimps.

Crossbreed dogs show more behavioural problems than pure breeds, study suggests

Research finds cockapoo, cavapoo and labradoodle dogs display more undesirable behaviours than breeds they derive from

The UK has oodles of doodles but a study might offer paws for thought: researchers have found some of these designer crossbreed dogs show more behavioural problems than the pure breeds from which they derive.

Crosses between poodles and other dog breeds have become increasingly popular in the UK, with research suggesting the trend is – at least in part – driven by the expectation such dogs will be hypoallergenic, healthy and good with children.

Wild-born birds recruited to teach critically endangered regent honeyeaters their lost songs

Researchers hope restoring the original song will improve breeding prospects for birds released into the wild

Scientists have rescued the lost song of the critically endangered regent honeyeater – one of Australia’s rarest birds.

Regent honeyeaters were once seen in vast flocks across south-eastern Australia, with a distribution that ranged from Queensland to Kangaroo Island in South Australia.

City of Catania calls ruse to avoid CCTV cameras installed to stop fly-tipping ‘as cunning as it is doubly wrong’

A man in Catania, Sicily, trained his dog to dump bags of rubbish by the roadside in an attempt to evade surveillance cameras installed to combat fly-tipping, municipal police have said.

The episode was detailed in a post on the city of Catania’s official Facebook page. Accompanying a video of the dog was a remark from the police that “inventiveness can never become an alibi for incivility”.

Gone in 60 milliseconds: dramatic slow-motion snake bites reveal clues about how fangs and venom kill prey

Posted on by

Vipers target with precision, elapids bite repeatedly and colubrids saw their way in – and if they strike too fast, they might lose their teeth

Venomous snakes must strike fast to sink their fangs in prey before they startle – as quickly as 60 milliseconds when hunting rodents.

New research has captured – in slow-motion footage – the differences in how venomous serpents bite their targets.

Grisly recording reveals bat catching, killing and eating robin mid-flight

Posted on by

Before the Spanish study, some scientists had been sceptical about the mammals attacking migratory birds

Bats are generally viewed as harmless, if spooky, creatures of the night. But scientists have revealed a more savage side, after witnessing a greater noctule bat – Europe’s largest bat species – hunting, killing and devouring a robin mid-flight.

The grisly recording reveals the bat as a formidable predator, climbing to 1.2km (4,000ft) before embarking on a breakneck-speed dive in pursuit of its prey. On capture, the bat delivered a lethal bite and subsequent chewing sounds, recorded between echolocation calls, indicated that the bat consumed the bird continuously during flight for 23 minutes without losing altitude.

Wild chimpanzees filmed by scientists bonding over alcoholic fruit

Footage of apes consuming fermented breadfruit leads researchers to ask if it may shed light on origins of human feasting

Humans have gathered to feast and enjoy a tipple together for thousands of years, but research suggests chimpanzees may also bond over a boozy treat.

Wild chimpanzees in west Africa have been observed sharing fruit containing alcohol – not in quantities to get roaring drunk but, possibly, enough for a fuzzy beer buzz feeling.

LED lights on underside of surfboards may deter great white shark attacks

Posted on by

An Australian-led study using seal-shaped decoys found underside lighting disrupted ability of great whites to see silhouettes against sunlight above

Using LED lighting on the underside of surfboards or kayaks could deter great white shark attacks, new research suggests.

In an Australian-led study using seal-shaped decoys, underside lighting disrupted the ability of great whites to see silhouettes against the sunlight above, reducing the rates at which the sharks followed and attacked the artificial prey. The brighter the lights, the more effective the deterrent was.

Elephants can wash with a hose – and sabotage shower time, scientists say

An elephant at Berlin zoo used its trunk to interrupt flow of water from hose used by another elephant

If you get frustrated by the shower hog in your house you’re not alone: research suggests such behaviour might even irritate elephants.

Scientists say they have not only discovered an elephant with an astonishing ability to shower with a hose, but spotted another cutting off the flow of water – possibly in a deliberate act of sabotage.

$10m prize launched for team that can truly talk to the animals

AI expected to help researchers unlock two-way communication, say team that includes Tel Aviv University

In the Dr Dolittle books and films, the ability to “talk to the animals” captured the imagination. Now scientists are being offered a $10m prize to create real conversations.

The Coller Dolittle Challenge for Interspecies Two-Way Communication has been launched by the Jeremy Coller Foundation and Tel Aviv University. While the use of AI is not obligatory, the team say the technology can boost almost all proposals.

Fox bones at ancient burial site suggest animal may have been kept as pet

Clues at Argentina site raise possibility mammal was buried with human owners about 1,500 years ago

The remains of a fox unearthed at a human burial site in Argentina dating back 1,500 years has raised the possibility the animal may have been kept as a pet, research suggests.

Experts say the remains predate the arrival of domestic dogs in Patagonia, which occurred about 700–900 years ago, with a number of clues suggesting the fox was seen as valuable, and may even have been a companion to the hunter-gatherers it lived with.

Psychologists investigate meerkats’ response to human emotions

Researchers explore whether the animals adapt their behaviour in response to people’s happiness, sadness or anger

They are known for living in packs and being sociable animals. Now meerkats are being investigated to see if they can also pick up on human emotions.

Researchers and psychologists from Nottingham Trent University are studying meerkats in zoos to see if they can detect emotions such as happiness, sadness or anger from people, and whether they then adapt their behaviour accordingly.

Crows and magpies using anti-bird spikes to build nests, researchers find

Dutch study identifies several examples of corvids’ ‘amazing’ ability to adapt to the urban environment

Birds have never shied away from turning human rubbish into nesting materials, but even experts in the field have raised an eyebrow at the latest handiwork to emerge from urban crows and magpies.

Nests recovered from trees in Rotterdam in the Netherlands and Antwerp in Belgium were found to be constructed almost entirely from strips of long metal spikes that are often attached to buildings to deter birds from setting up home on the structures.

Feline uncertain? Cats do give clues if the fur’s about to fly, study finds

Study of 105 pairs of interacting felines decodes the cat behaviour that puzzles humans – and flags up the unsubtle battle cry of claws and yowling

When cats get together it can be difficult to tell rough and tumble play from a full-blown scrap. Now researchers say they have decoded feline behaviour to help owners spot when the fur might be about to fly.

Dr Noema Gajdoš‑Kmecová, first author of the research from the University of Veterinary Medicine and Pharmacy, in Košice, Slovakia – a cat owner herself – said understanding feline interactions could be difficult.
