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?

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.

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.

Hundreds of sheep have been given refuge at Farm Animal Sanctuary. Over time, they have divided naturally into two large flocks of around 200. All the sheep spend winter living together in large barns and yet in Spring, year after year, they will choose to re-group into almost exactly the same flocks as before.
Cambridge scientist Keith Kendrick found that sheep can remember at least 50 different faces for over 2 years.
These observations show the strength of sheep social bonds and the importance of respecting these relationships in modern farming systems. Sheep are often separated from their usual companions during transport, at transit points and at slaughter. Compassion believes that full account of animal sentience must be taken throughout an animal’s life.

Janet Taylor of Farm Animal Sanctuary near Worcester told us this touching tale of two sheep. Jasmine was a mature ewe who hadn’t had a lamb for 6 or 7 years. A group of newly rescued sheep moved into the field next to her, including some orphaned lambs, and over the next few days she began calling to one orphan named Alfie. He was calling back to her and eventually Janet decided to put him over the fence to be with her – and see what happened.
Alfie began to try to suckle Jasmine, as he would have done his biological mother, and Jasmine let him do so. Janet felt that at least this would provide him with the comfort of contact with a ‘mother’ but continued to bottle-feed him. Amazingly, Jasmine began to produce milk herself and was able to feed her newly adopted lamb as her own.
We have heard about a number of female animals who have adopted and fed orphaned youngsters. This even happens across species; for example, pigs are known to have adopted newborn puppies.
This shows the strength of both the maternal instinct and the need to have care from a mother figure. Perhaps all the species we commonly farm have this need but sadly, they are often denied it. In the light of our modern scientific understanding of animal sentience, Compassion in World Farming believes that farming policy and practice must take full account of animal sentience – as is required by European Union law.
