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?

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.

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.

It is well known that pigs are intelligent and curious. In nature, sows make a secure nest for their piglets and there are strong bonds between mother and young.
Recent research with pigs found that they have “episodic-like memory” – a particular kind of memory which indicates highly developed mental abilities.
Despite our knowledge of their sentience, the majority of the world’s pigs are kept in factory farms. And if the animal welfare reasons are not enough to end factory farming, swine flu may give us another reason. Cramped, stressed animals in filthy conditions provide the ideal breeding ground for bugs. (The link takes you to a short clip on CNN News with disease expert Dr Michael Greger).

High welfare, free range or preferably organic systems can provide a much better life for pigs. Let’s give them space, fresh air and a life worth living.
