Crows safeguard sticks to speed future food-finding forays. Earth - Cuddly sifakas fight off huge marauding snake. Indiana Jones might have struggled to cope with snakes, but Coquerel's sifakas evidently know exactly what to do.
One of these Madagascan primates was attacked last year by a large snake called a Madagascar ground boa. But the other members of her troop attacked the snake, eventually hurting it so badly it died. The incident is described in the journal Primates. The snake attack was witnessed by four hotel workers in Madagascar on 24 March 2014. They subsequently described what happened to Charlie Gardner of the University of Kent in Canterbury, UK and his colleagues. 9 questions about penguins you were too embarrassed to ask. Today is Penguin Awareness Day.
Truth be told, this is an incredibly silly holiday. We should be honoring this majestic beast every day of our lives. Alas, we have just Penguin Awareness Day in January and World Penguin Day in April. Dolphins Use Sponges To Access Novel Food Sources. Indo-Pacific bottlenose dolphins around Shark Bay, Australia, perform a unique behavior called “sponging”, which is where certain animals place sponges over their snouts during foraging activities.
Not all of the dolphins in this area display the behavior, and it was discovered that sponging was in fact culturally transmitted. Although it seemed plausible that sponging could be classified as tool use, it remained a mystery what the precise purpose of this behavior was; scientists postulated that it could serve to protect their beaks against abrasion from sharp objects whilst foraging for food. A new study aimed to shed light on why these animals might be using these sponges; in particular, whether sponging allowed the animals to access certain novel resources that non-spongers could not.
They found evidence that the animals used sponges as tools to access food, meaning that they could exploit an otherwise unused niche. Methods Made Manifest - Episode 2. Methods Made Manifest - Episode 1. Speeding Towards Birds In A Car… For Science! Cunnilingus increases duration of sex in megabat species. The males of a species of megabat have been observed giving oral sex to females in a move that appears to prolong the duration of copulation, a study has shown.
A team of biologists from Madurai Kamaraj University observed 57 separate incidences of copulation in a colony of Indian flying foxes (Pteropus giganteus), a giant species of bat. Before mating, males would typically groom their penis before approaching a nearby female. Females typically moved away, and the males would follow. When the females stopped moving, the males would start licking the female's vagina for around a minute. In the vast majority of cases (57 out of 69), the male then mounted the female for sex -- the act itself lasted between ten and 20 seconds. Chimps' Answer to Einstein. How do elephants trumpet? At last, scientists figure it out. Elephants' deepest calls can thunder up to 6 miles (10 kilometers) away.
Now, researchers have learned for the first time how the massive animals produce these sounds.

Gorilla Youngsters Seen Dismantling Poachers' Traps—A First. "This is absolutely the first time that we've seen juveniles doing that ... I don't know of any other reports in the world of juveniles destroying snares," said Veronica Vecellio , gorilla program coordinator at the Dian Fossey Gorilla Fund 's Karisoke Research Center , located in the reserve where the event took place. "We are the largest database and observer of wild gorillas ... so I would be very surprised if somebody else has seen that," Vecellio added. BBC Nature - Crows know familiar human voices.
11 May 2012Last updated at 12:16 By Victoria Gill Science reporter, BBC Nature The researchers noted when crows turned their heads towards the sound of a familiar voice Crows recognise familiar human voices and the calls of familiar birds from other species, say researchers.
The ability could help the intelligent birds to thrive in urban environments; using vocal cues from their human and avian neighbours to find food or be alerted to potential threats. The team used recordings of human voices and jackdaw calls to test the birds' responses. They published the findings in the journal Animal Cognition. Lead researcher Claudia Wascher from the University of Vienna said that, although it was widely known that crows were "very intelligent", most studies had focused on their ability to recognise and communicate with their own species.
"In cities crows live alongside jackdaws, magpies and seagulls, and alongside humans," Dr Wascher told BBC Nature. Baboons Appear to Recognize Words From Gibberish. BBC Nature - Brown bear exfoliates using rock as a tool. 6 March 2012Last updated at 12:04 The brown bear scrubbed its face using a barnacle-covered rock A wild brown bear has been photographed using a barnacle-covered rock to exfoliate in the first recorded act of tool use by the species.
The observation was made in Glacier Bay National Park, Alaska by the University of Cumbria's Dr Volker Deecke. The bear may have been using the rock to scratch irritated skin or remove food from its fur while moulting, Dr Deecke says. Fish mimics octopus that mimics fish. Science Can Neither Explain Nor Deny the Awesomeness of This Sledding Crow - Alexis Madrigal - Technology. Before we talk, you need to watch the video above.
It's just one minute and 24 seconds. You'll observe a crow (probably a 'hooded crow') pick up the lid to a jar, set it down on the apex of a snow-mottled roof and slide down one side, carefully keeping its feet on the lid until it gets to the bottom. Then it picks up the lid, flies back to the apex, tests out another face of the roof, finds it lacking, returns to the original position, and slides down again. Guest Post! It’s About Time: Delving Into Animals’ Memories. Editor’s Note: Today’s post, coming appropriately after yesterday’s post on human intuitions about memory, comes from Felicity Muth who blogs at Not Bad Science, and tweets as @FelicityMuth. This post, while it can certainly stand alone, is meant to be read after reading Felicity’s contribution to The Guest Blog. We have known for a number of years now that it is possible for animals to have memories for past events or episodes in their lives as we do.
Animal Imagination: The Dog That Pretended to Feed a Frog (and Other Tales) Can dogs pretend?
This is the question I asked yesterday, prompted by Sheril’s story: …this afternoon Happy did something unusual. She carried a toy frog over to her water bowl, and gently put it down as pictured. Given its orientation, I’m skeptical that her placement was an accident.The frog continues to sit like this (20 minutes later) as Happy arranges other toys nearby. Now I admit I may be anthropomorphizing, but her behavior sure reminds me of a child playing “make believe” with stuffed animals. Empathic rats spring each other from jail. You enter a room with two cages.
One contains a friend, who is clearly distressed. The other contains a bar of chocolate, which clearly isn’t. What do you do? While a few people would probably go for the chocolate first (and you know who you are), most would choose to free the friend. Guest Post: the Nature of Octopuses.
