The ability to co-operate with your companions is believed to show a higher level of thought – and is an ability once thought to be unique to humans. In a recent study hyenas were found to be great team players, with a 100% success rate in a group challenge. They had to work together to reach food from a platform which they couldn’t get to alone. It was even found that when a hyena who had worked out the ‘platform puzzle’ was paired up with one who was new to it, the experienced hyena changed his behaviour – as we would when showing someone a new task.

Chimps in Japan have been seen helping their companions out, purely on the basis of need. They would hand tools over to chimps in a nearby pen; and most notably this was most likely to happen if the chimp really needed the tool and requested it, rather than if they just wanted it to play with. This shows that chimps care about the welfare of their fellows and will assist them even if there is nothing to be gained themselves.
This helping is not just reserved for other chimps too – in a previous study by Warneken, chimps were also witnessed helping humans in a similar task and handing a stick to them on request. Videos of both of these experiments can be found below.

If by the word ‘language’ we mean a system of communication, animals have different languages of their own. Hens and chickens have over 30 different calls, which they use to alert their group to food or danger, for example. Chicks start communicating with their mother hen while they are still in the egg and cockerels have a special food call to let the hens know that food has been found. Hens make a gentle crowing sound when they are happy.

Pigs are very chatty, communicating with grunts, squeals, snarls and snorts, champing their jaws and clacking their teeth. Sows have a special call for their piglets when it’s time for the piglets to suckle. Sows and piglets keep contact with each other and with their mother by squeals and grunts. If piglets are separated from Mum, they squeal for her. Scientists found that sows responded more strongly to the desperate squeals from cold, hungry piglets than they did to calls from larger, more well-fed piglets.
Animals can also understand each other’s language. For example, some animals can understand the meaning of another’s alarm call.
Dogs and humans have a long history of living together. While dogs are often quick are picking up what humans are saying – perhaps by the tone of voice rather than by all the actual words – we humans often seem to struggle to understand dog ‘bark language.’ In this really interesting video, courtesy of the social networking site Petstreet , dog communication expert John Rogerson helps us decipher what our furry friends are wanting to tell us.
Sakura, a baby chimpanzee, is showing that chimps prefer melodic music. During a research trial to see which kind of music Sakura would chose, she preferred to listen to a pleasant melody than to discordant musical chords.

This shows us more fascinating evidence about the sentience of chimps. In this case, Sakura is in a human-designed, captive environment, which may be somewhat enriched, but which is still unnatural for a chimp. The fact that Sakura works out what to do in these circumstances tells us even more about chimp awareness and understanding. These abilities are strong indicators of animal sentience.
Sakura is not alone in preferring sweet music. Back in 2001, there was research investigating how cows reacted to fast beats or to softer music. The researchers said: “We found that slow music improved milk yields perhaps because it relaxes the cows in much the same way as it relaxes humans.”
Despite increasing awareness of animal sentience, there is still resistance to appreciating or acknowledging that animals are sentient beings and there is reluctance to peer over the barrier of “human vs other animals” that we ourselves have created.

It was previously thought that this kind of choice and preference about music was a “uniquely human trait.” So we see that Sakura and the dairy cows have overcome yet another barrier!
As reported in the Daily Mail, Clyde is blind, and Bonnie leads him “to food or water, and lets him rest his head on her haunches when he feels a bit lost. They are inseparable, and if Bonnie isn’t nearby Clyde refuses to move a paw.”
Bonnie and Clyde were rescued as strays recently and now they happily have a new home. The BBC’s One Show has a special page and film about these two great friends.
Mila is a beluga whale at an aquarium in Harbin, NE China. The pool she lives in has an arctic temperature and is also used by divers. In a recent exercise, diver Yang Yun got into trouble and was unable to kick her way back up the surface. But suddenly she felt herself being pushed upwards – Mila was rescuing her.
According to reports, “Mila had spotted her difficulties and using her sensitive dolphin-like nose guided Yun safely to the surface.”
One of the staff is quoted as saying: “Mila noticed the problem before we did. She’s a sensitive animal who works closely with humans and I think this girl owes her her life.”
Belugas are very social and because they are so chatty, they are also known as sea canaries. When you have to swim great distances under ice in the Arctic Sea, it helps to be a good communicator so you can keep up with your pod and let each other know what’s going on. Sadly, beluga whales are yet another threatened species.

Dr Jane Goodall’s pioneering studies of wild chimpanzees revolutionised our knowledge about the sentience of these amazing animals.
This event is an exciting chance to meet Dr Goodall, hear more about her fascinating life and work, and take part in an informative question and answer session. Tickets are £20 for members of the Jane Goodall Institute and £40 for non members.
Mockingbirds can quickly recognise individual humans who seem to be a threat to their nest. After only a short time, the birds recognise someone who has bothered them and make big efforts to drive them away. But they ignore other passers-by or nearby strangers.
This research took place at the University of Florida, where Professor Doug Levey, a zoologist, is reported as saying:
Mockingbirds can quickly learn to recognise individuals
“We don’t know whether it’s unique to mockingbirds, but it does suggest these birds are a heck of a lot more intelligent than people have ever given them credit for. People have known for a long time that crows and parrots for example have a lot of intelligence. But these birds are fairly small. … It’ll change the way people view the intelligence of birds like this.”
The mockingbirds live in what is considered to be a natural environment, and researchers say their scientific paper will be the first published research to show that “wild animals living in their natural settings recognize individuals of other species.”
These clever birds show us yet again that we need to respect animals’ abilities when human actions affect their lives.
LuLu the Vietnamese pot-bellied pig is a star pig. When her human companion suffered a heart attack in their isolated holiday home, thirteen-month old LuLu charged to the rescue.
She squeezed through the ‘dog door’, scraping herself in the process, and headed for the road. This meant her leaving the fenced yard, which she never usually did on her own.
Then she laid in the road waiting for a car to stop. According to witnesses, it took 45 minutes before a kind driver did get out to see what was up. LuLu led him to the house and Jo Ann’s life was saved.
A follow-up article reported that the world was fascinated by LuLu’s courage and clever action. LuLu has had worldwide media coverage and TV appearances and she has been given a gold medal from the American Society for the Prevention of Cruelty to Animals.
