Parrot comes to puppies’ rescue

Sam, an 18-year old African Grey parrot, has helped save the lives of five premature puppies. It is reported that in the middle of the night, Sam flew upstairs to his owner’s bedroom calling “Come on, come on!”, mimicking his owner’s frequent command to her dog, Sally.

In the eight years he had lived at the house, Sam had never before been in the bedroom.

Going downstairs with Sam, the owner looked in the kitchen and found Sally and her newly born premature puppies in distress on the floor.

The story of Sam is remarkable for many reasons! He was aware of the distress of the dogs – animals of a species different to himself. This ‘interspecies awareness’ can be used by animal scientists as an indicator of animal sentience.

The words “come one, come on!” are used to encourage action or a bit more speed from another, and often they imply some urgency. We don’t know in which context Sally’s owner uses these words to her, but the signs are that Sam the parrot chose these words deliberately to get the urgent response needed.

African Grey parrots are well known for their intelligence and quick wit, and here is yet another example of their abilities.

Dr Irene Pepperberg has carried out extensive studies of parrots’ abilities to understand. Reporting on her findings, she notes: “Given the evolutionary distance between birds and mammals, these results have intriguing implications for the evolution of intelligence, the study of comparative intelligence, and the care and maintenance of birds held in captivity in zoos and as companion animals.”

 This  short film featuring Irene with famous parrots Alex and Griffin gives a very interesting and though-provoking snapshot about these amazing birds.

Chimps free at last

This wonderful film clip is of chimpanzees who are being released to the freedom of a sanctuary. Most of them have endured many, many years of confinement in a laboratory.

Most were snatched from the wild as infants, and some bred in a laboratory, and used in medical experiments. Their reactions as they venture into the outside world clearly show that chimps are sentient, emotional beings.

It’s well worth visiting the sanctuary’s website for great photos of the chimps and their individual stories.  How fantastic that these chimps finally have a life worth living!

Saving Valentina the whale

Whales are sentient beings

There is growing awareness and understanding of the intelligence, understanding and behaviour of whales. Science shows that whales are sentient beings. This means they can suffer fear, pain and other negative states – but that in good circumstances, they also have the ability to enjoy life.

Saving Valentina

Members of the Great Whale Conservancy sighted a young whale who was so entangled in fishing net that she could not move. If they could not free her, she faced certain death.

It must have been nerve-wracking for all parties as the brave rescuers painstakingly hacked away the imprisoning net with the one small knife they had with them. But eventually, they managed to set the whale free and for an hour afterwards, she gave a dramatic display of leaping and diving in what her rescuers felt it was a show of joy. She must have felt wonderful to have been released from the fatal net and she may well have been trying to attract the attention of the rest of the pod of whales, and perhaps her mother.

They named the youngster Valentina and you can see the wonderful film here.

 

Divers rescue whale … and whale rescues diver

We’ve previously written about the rescue of a humpback whale who had become fatally entangled in crab lines. But happily, she was spotted and freed by divers. When she had been freed, she swam around in circles and then went up to each diver one by one and nudged them. One of the rescuers is reported as saying: “It seemed kind of affectionate, like a dog that’s happy to see you … I never felt threatened. It was an amazing, unbelievable experience.”

Mila is a beluga whale in China. Brave Mila rescued a diver who had got into difficulties while practising in the pool. Using her sensitive, dolphin-like nose, Mila guided the diver 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.”

Mother hen

Hens with chicks are well known to be protective and caring of their offspring.  Not only are hens concerned for their chicks’ safety and well-being,  but they feel empathy,  described by scientists as “the ability to be affected by, and share, the emotional state of another”.  Scientists at the University of Bristol, UK, exposed mother hens and their chicks to puffs of air.  When the air puff was directed at the hens, they reacted with signs of fear, becoming more alert and preening less, and their eye temperature decreased. When their chicks were exposed to the puffs of air, the hens showed all these signs but in addition, their heart rate increased and they made more clucking calls to their chicks - strong signs of their concern.     

Mother hens feel empathy for their chicks

Mother hens feel empathy for their chicks

Researcher Jo Edgar said: “We found that adult female birds possess at least one of the essential underpinning attributes of ‘empathy’; the ability to be affected by, and share, the emotional state of another.”

The researchers used chickens for this study because in commercial farming, as they pointed out, “chickens will regularly encounter other chickens showing signs of pain or distress due to routine husbandry practices or because of the high levels of conditions such as bone fractures or leg disorders.”

Scientists have also found that hens can anticipate future events based on previous experience, and make judgements accordingly; they have over 30 different calls for clear communication with each other; and chicks can count!  But these abilities and the sentience of hens and chickens are sadly disregarded in commercial farming conditions. Today’s study on hens and empathy gives yet more weight to the urgent need for more humane farming systems, in which animals can carry out their natural behaviours. Animals are sentient beings, and  what happens to them, matters to them.

Monkey co-operation and fairness

The 2007 BBC documentary: “Capuchins: The Monkey Puzzle”, captures a pair of capuchin monkeys showing very compelling signs of cooperation and a sense of fairness. 

In the first experiment the monkeys work together to solve a problem using tools.  On one side of a see-through divide is a box of hazelnuts and on the other is the flint which is needed to open the lid of the box. One monkey has the rock but cannot reach the nuts; the other monkey has the box of nuts, but has no way of getting them out without a rock. In an act of teamwork, one monkey offers the rock to the other, who uses it to open the box and get out the nuts. He then fairly shares the nuts equally, three for himself and three for his teammate. They worked together to successfully solve a puzzle that they could never have done alone.

The second experiment also suggests that capuchin monkeys understand fairness. Two monkeys were first trained to hand over a white chip to receive a food reward. When the two monkeys were given unequal rewards, the monkey receiving the less desirable treat would rather refuse the reward and go hungry on principal than accept anything less than an equal reward.

The language of dance

Honey bees are social insects that have been shown to co-operate with other individuals in their colony. Worker bees (sterile females) have many duties in the colony. One job of a worker bee is to forage for food. They leave the hive to search for nectar (their source of energy and from which they make honey) and pollen (their source of protein) from flowering plants.

Honey_bee copyright free Once a forager has found pollen or nectar they will return to the hive and perform an elaborate dance on the vertical surface of a honey comb. Karl von Frisch discovered that bees use this dance to communicate the location of food to others in their hive. If the food is relatively far from the hive (as it generally is) the bee will perform a “waggle dance” to communicate two items of information – the distance to and the direction of the food source.

A bee that performs a waggle dance moves in a figure of eight. She waggles her body from side to side and emits a buzzing sound as she moves forward in a straight line, then circles to the right, back to her starting point, waggles ahead again, and then circles to the left and waggles again. This pattern is repeated a number of times.

The duration of the straight run, or “waggle,” tells the other bees how far the nectar or pollen is from the hive. As the distance to the food source increases, the duration of the waggle also increases.

The direction in which the dancing bee faces during the straight portion of her waggle dance indicates the location of the food source in relation to the sun. For example, if the flowers are located 30 degrees to the right of the sun, the dance will be oriented 30 degrees to the right of vertical.

The waggle dance acts as a form of language – the other foragers watch the dancing bee’s movements and receive information about how to get to the food source. They also receive information about what is to be found at the food source through their sense of smell.

How a worker bee communicates the location of food source to other bees in the hive may be one of the most complex forms of social behaviour seen outside of the human race.

Here’s a great video about these amazing bees.

Cultural Transmission and Tool-use in Orangutans

We are finding out more and more about animals who use ‘tools’ in their daily lives. Animals in a group may also learn from each other and pass this information on to each other. Scientists call this ‘cultural transmission’.

The first documented case of wild orangutans making and using tools was reported from a population of orangutans in Indonesia in 1996. They used tools which they had crafted either for extracting insects or seeds to eat.

Researchers then went on to look at how tool-use varied between orangutans living in different regions. They compared the tool-use of orangutans at six different areas. It was found that the different orangutan populations behaved differently and these differences were greatest between groups living furthest apart. Orangutans who lived in larger groups and who were socially tolerant used tools more than those who were isolated.

The evidence suggested that the differences in behavior were cultural: firstly, because the extent of the differences increased with distance, and secondly, because the extent of the orangutans’ tool-use increased according the amount of social contact in their group. Social contact increases the amount of cultural transmission.

This video clip shows orangutans at a sanctuary copying behaviours they learned through observing their human counterparts. They learned how to manoeuvre a canoe, paint, wash with soap and even use a saw!

Orangutans are fascinating animals but their future is under threat. Their rainforest habitat is being cut down at an alarming rate for logging and agriculture, including plantations of palm oil, a vegetable oil widely used in food and everyday products. You may wish to choose products which do not contain palm oil. Some companies claim to use sustainably-produced palm oil.

Understanding you

This is the incredible story of a whale rescue and the response of the whale to her rescuers.

The humpback whale was on the migratory route around the California coast when she became terribly entangled in crab trap lines. Her life was at great risk.
She was tangled up in weighted ropes up to 240 feet long around her tail, her flipper and even in her mouth. The ropes were so tight they cut into her blubber and caused visible wounds. She was completely helpless  and the weight of the traps was causing her to struggle to keep her blow hole out of the sea.

A rescue team of divers went out to her but she was in such a state  they were  unsure that they stood any chance of saving her. They were at risk themselves, as the flick of a humpback’s tail can kill a human.

But they reported that as they worked to free the unfortunate creature, she did not struggle at all and they were aware of her eyes simply following them around as they worked.

Thankfully, the rescuers were successful but must have been astonished by the whale’s heartwarming response. When she felt herself come free, she began to swim around in circles and then went up to each diver one by one and nudged them. One of the rescuers is reported as saying: “It seemed kind of affectionate, like a dog that’s happy to see you … I never felt threatened. It was an amazing, unbelievable experience.”

Her response makes us think about the common ground that humans can have with animals who might appear so very different from us. A whale-watching expert who helped co-ordinate the rescue is quoted as saying: “You hate to anthropomorphize too much  but the whale was doing little dives and the guys were rubbing shoulders with it … I don’t know for sure what it was thinking, but it’s something that I will always remember. It was just too cool.”

An interesting point about our understanding of these large sea mammals was made by Gould and Gould in their book ‘The Animal Mind’. They suggest that perhaps we have been quicker to appreciate the intelligence and sentience of primates as they are so much more similar to us in their gestures and experiences, and therefore easier for us to read. We may have been slower to understand the complexity and richness of underwater creatures simply because they appear to be so very different to us.

Horses: Their Behaviour, Mental Abilities and Welfare

Horses have played a huge part in our lives for hundreds of years. Yet how much do we actually know about them?

Animal welfare consultant Heather Pickett has written a special article for our animal sentience pages. It’s a fascinating  read  about  horses’ behaviour, cognitive abilities (such as ‘thinking’) and welfare needs.  Horses have remarkably complex social lives; with membership of a herd being of ultimate importance to them and sometimes roaming for up to 80km in one day. They are great diplomats, able to resolve many conflicts in order to keep the herd together.

Mares often form lifetime relationships, spending most of their time together. Their foals often become good friends too as a result. They have remarkable memory skills and have even been shown to understand that a 3-D image can be shown in a photograph. For example, horses had been trained to have a ‘favourite’ object (for example a soft toy or a frisbee), using treats as positive reinforcement. Then they were shown photos of a range of things, including their ‘favoured toy’, and more often than not they would choose the photo of that toy. In a similar experiment (Stone 2009), horses were found to be able to tell the difference between photos of people, even identical twins!

Domesticated horses are often kept stabled alone and fed on concentrated food that is eaten quickly, rather than grazing the whole day as they would do in more natural conditions. These factors sometimes lead to destructive behaviours such as weaving, biting the stable doors and pacing. The occurrence of these unnatural behaviours illustrates that horses, just like many other animals, need an environment that more closely fits their needs and fully takes into account their sentience and intelligence.

Reading you like a book

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

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?
