Horses are great at reading body language, even that of the humans around them – in fact a horse known as ‘Clever Hans’ was able to answer mathematical questions by tapping his hoof, based on the very subtle signals given out by the person asking the question! Even though they didn’t mean to give any secret messages to the horse, he could read small changes in facial expression or intakes of breath – and then work out what the right answer was!
Clever Hans
At the time, people thought he was working out the maths himself, and were disappointed to learn that he was reading their body language instead. But the fact that Hans could answer the questions by this method is in itself amazing. He was seeing small changes in the behaviour of his questioners which people did not see – and it took an extensive experiment for us to find out what Hans knew all along.
Other animals are also more tuned in to us than we might expect. In a previous post about Sociable sheep we found out that sheep preferred the faces of smiling people rather than stressed or angry people.
This leads us to consider, how much do animals really know about what we’re thinking?

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.

A recent test found that pigs understand mirrors, and can learn where a food bowl is through looking at the reflection. One group of pigs had time to get used to the mirror before they were tested, and another group were only shown a mirror at the beginning of the test. A hidden food bowl was then shown to them in the mirror. The food bowl was empty – so the pigs would not be relying on their sense of smell to locate it.
All but one of the pigs who were familiar with the mirror found the food bowl in less than 23 seconds – whereas the pigs who were new to it looked behind the mirror for the bowl.
Again, we see the amazing capacities of animals to work out their environment and shows the importance of using only high welfare farming systems as pigs easily become bored and frustrated in barren factory farms. At a minimum, all pigs should have access to bedding materials that let them root and explore like their wild ancestors.

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.
Bonnie and Clyde are inseparable border collies. Dogs are social animals so company is very important for them. But this is a bond with a difference: Bonnie is Clyde’s guide dog.
The Daily Mail reports that Bonnie leads Clyde “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. It appears they were lost in a storm and no-one has come forward for them. Obviously these two have a vital bond and they must be rehomed together.
