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.
Following on from our post on the 6th November about Jasmine and Alfie, here are two more stories about care of young animals by other animals. This time it’s the turn of the grandmothers to teach us a thing or two about caring for animals. One of Compassion in World Farming’s supporters kindly supplied us with this story. Her neighbour gave a home to two generations of goats. When the youngest had her goat kid, she didn’t seem to know what to do. Even though the goat kid was repeatedly shown where to suckle, the two just didn’t seem to connect.
The grandmother saw what was happening and stepped in to help, even producing milk for the youngster. From then on she took it in turns with the mother to care for the kid, being there to support the mother goat and also ensure the kid had plenty of food.
Across the generations
Another example of grandmothers helping out was in the news last week. Researchers in Japan had been observing free-ranging macaque family groups when they noticed some interesting situations. A grandmother macaque took over the care of her grandchild when the mother disappeared; carrying, grooming and allowing her to suckle, although the researchers believe she didn’t produce any milk. Perhaps letting the baby macaque suckle may have been an act of reassurance for the youngster.
When the mother returned after a period of time (believed to be 6-14 days) she resumed her duties in caring for the youngster. Another grandmother was witnessed ‘sharing care’ with a struggling mother, and this time was believed to be producing milk as well.
A key feature in all of these stories is the fact that the grandmother was prepared to get involved quickly if needed, but was not overly possessive of the youngster. In both cases they seemed happy to share care with the mother, or hand the infant back when their job was done. This shows sensitivity to the needs of the situation, and more flexible thinking than if they were to simply ‘take over’ an abandoned youngster.
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.

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.
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.
Snowball, a cockatoo who lives at a bird rescue centre, seems to love to dance. This clip shows us that Snowball can keep time as well as many humans!
Scientists looked at YouTube videos to see which animals could do this. Alex the African Grey parrot was famous for his abilities to count and to distinguish between colours and shapes – and he could also keep the beat. In fact, the video search found that 14 different species of parrot who kept time to music.
The scientists said: “Our analyses showed that these birds’ movements were more lined up with the musical beat than we’d expect by chance. … We found strong evidence that they were synchronizing with the beat, something that has not been seen before in other species.”
They suggest that the parts of the brain used for copying sounds are also involved in this ability to keep in time with the beat.
The hens and chickens that we farm are descended from the jungle fowl of south-east Asia. Jungle fowl and domestic chickens make over 30 different calls, which they use to alert their group members to a threat or to food, for example. Chicks start communicating with their mother hen while they are still in the egg and cockerels make a “food call” to let the hens know that food has been found.

Scientists used to think that only a few mammal species could really understand the meaning of different calls and grunts. Now, research is showing that hens and chickens have a more advanced use and understanding of language than scientists expected.
Recordings of cockerels’ food calls were played back to hens, either straight after they had received three corn kernels to eat, or after they had not received anything to eat.
In response to these recorded calls, the hens only went to look for food if they had not eaten any corn. The hens who weren’t hungry ignored the calls! They didn’t just go and search for the food as an automatic response to the call.
This shows that they understood that what the call meant and could make an intelligent response to it.
Other researchers found that hens were prepared to wait longer before eating a tasty treat, if they knew that waiting for longer would mean they received a bigger number of tasty treats.
