Planet, people and other critters, that is bioethics sensu lato. All living beings matter. Without diversity, the world becomes a dull place with little innovation… This is why we need inclusivity. Equality. Allowing everyone to live life to the full and in their own way, without any form of abuse. That includes me and other victims of sadistic stalking.
Do you agree with this? Don’t other species also have to respond to the circumstances around them, including being chased by humans, having been born in a zoo or as part of the pet trade or to droughts and food shortages, as well as the fact that humans take up more and more of their natural habitat and force them to live in our built environment?
I used to be quite fond of people in general, but I no longer like humans as much as I used to.
Humans have been on the planet only a short while, but no other species has managed to wreak even a fraction of the destruction that humans already have.
Humans also hunt and incarcerate each other, and sometimes kill each other, for no good reason. (Guantánamo, anyone? Migrant detention centres, anyone? 9/11 anyone? )
Humans approve of it when other humans want to build unhealthy concrete, plastic, steel and brick homes yet tend to object when other humans want to build homes made from branches and wood, or earth, or straw bales and adobe, or live in a hole excavated in the ground where they keep their books and the other kind of stuff that we all tend to have.
More and more humans, it looks like, gather and gather and gather, and steal, and build up reserves that would last them many lifetimes. It has a name, I believe. Consumerism.
So-called progress that happens for no more than the sake of the drive for bigger bigger bigger more more more has become the norm. (Third Heathrow runway, anyone?)
Sales for the sake of sales instead of the sake of contributing something worthwhile to the lives of others is still a major driver for many, as is the accumulation of monetary value, often to make up for feelings of inadequacy and insecurity.
“It’s amazing! I have X euros/dollars/pounds’ worth of merchandise in my shop right now!”
Even a so-called stupid bird brain of a quaker parrot knows that in times of plenty, all that matters is that you have food in your hands – not how much someone else has – and that you should start building up a little stack of reserves for yourself when you notice that food is scarce.
This spunky creature, a quaker parrot called Sioux, was part of my household for 21 years Her life and death have changed my life forever. She was still a youngster when she was brought to a wild-bird hospital in Florida where I was volunteering at the time. It was against the law to release her, and she was unable to fly, so she needed a home. I adopted her along with quaker parrot Mohawk. As I had noticed that these birds are never on their own in the wild, I wanted to adopt at least two of them, for increased well-being, and housed them together. Myiopsitta monachus.
Quaker parrots don’t round up other birds and their youngsters and put them in cages. They protect them, stand up for them (they stand up even for cats). In the wild, they share their amazing self-built homes that have separate spaces for various activities with other species, sometimes even predators. (Yet they are also highly territorial, protective of their homes.)
But many humans see them as “threats” and spread vile myths about them, mainly because their natural habitat was once limited to South-America.
Probably also because at some level, we humans feel threatened (challenged, made uncomfortable) by the intelligence and strong lively personalities of these birds. They can be highly opinionated.
Something similar goes for our city pigeons.
Birds have been on the planet so incredibly much longer than humans. They are highly aware of their own vulnerability (with to some degree the exception of birds of prey), so much that they will always try to hide it as well as they can. They don’t go around destroying their own habitat, and they tend to live quite peacefully with other species.
Humans are only one species. Homo sapiens.
We humans haven’t really learned a thing yet, have we?
These two embedded tweets below are supposed to show one image and one video.
Humans are like no other species. We have constructed stratified states, colonised nearly every habitat on Earth and we’re now looking to move to other planets. In fact, we are so advanced that some of our innovations – such as fossil fuel technologies, intensive agriculture and weapons of mass destruction – may ultimately lead to our downfall.
Even our closest relatives, the primates, lack traits such as developed language, cumulative culture, music, symbolism and religion. Yet scientists still haven’t come to a consensus on why, when and how humans evolved these traits. But, luckily, there are non-human animals that have evolved societies and culture to some extent. My latest study, published in Nature Evolution & Ecology, investigates what cetaceans (whales and dolphins) can teach us about human evolution.
The reason it is so difficult to trace the origins of human traits is that social behaviour does not fossilise. It is therefore very hard to understand when and why cultural behaviour first arose in the human lineage. Material culture such as art, burial items, technologically sophisticated weapons and pottery is very rare in the archaeological record.
One prevailing explanation is the social brain hypothesis, which argues that our minds and consequently our brains have evolved to solve the problems associated with living in an information rich, challenging and dynamic social environment. This comes with challenges such as competing for and allocating food and resources, coordinating behaviour, resolving conflicts and using information and innovations generated by others in the group.
However, despite the abundance of evidence for a link between brain size and social skills, the arguments rumble on about the role of social living in cognitive evolution. Alternative theories suggest that primate brains have evolved in response to the complexity of forest environments – either in terms of searching for fruit or visually navigating a three dimensional world.
Under the sea
But it’s not just primates that live in rich social worlds. Insects, birds, elephants, horses and cetaceans do, too.
The latter are especially interesting as, not only do we know that they do interesting things, some live in multi-generational societies and they also have the largest brains in the animal kingdom. In addition, they do not eat fruit, nor do they live in forests. For that reason, we decided to evaluate the evidence for the social or cultural brain in cetaceans.
Another advantage with cetaceans is that research groups around the world have spent decades documenting and uncovering their social worlds. These include signature whistles, which appear to identify individual animals, cooperative hunting, complex songs and vocalisations, social play and social learning. We compiled all this information into a database and evaluated whether a species’ cultural richness is associated with its brain size and the kind of society they live in.
We found that species with larger brains live in more structured societies and have more cultural and learned behaviours. The group of species with the largest relative brain size are the large, whale-like dolphins. These include the false killer whale and pilot whale.
To illustrate the two ends of the spectrum, killer whales have cultural food preferences – where some populations prefer fish and other seals. They also hunt cooperatively and have matriarchs leading the group. Sperm whales have actual dialects, which means that different populations have distinct vocalisations. In contrast, some of the large baleen whales, which have smaller brains, eat krill rather than fish or other mammals, live fairly solitary lives and only come together for breeding seasons and at rich food sources.
We still have much to learn about these amazing creatures. Some of the species were not included in our analysis because we know so little about them. For example, there is a whole group of beaked whales with very large brains. However, because they dive and forage in deep water, sightings are rare and we know almost nothing about their behaviour and social relationships.
Nevertheless, this study certainly supports the idea that the richness of a species’ social world is predicted by their brain size. The fact that we’ve found it in an independent group so different from primates makes it all the more important.
Can one form a friendship with a magpie? –even when adult males are protecting their nests during the swooping season? The short answer is:“ Yes, one can” – although science has just begun to provide feasible explanations for friendship in animals, let alone for cross-species friendships between humans and wild birds.
Ravens and magpies are known to form powerful allegiances among themselves. In fact, Australia is thought to be a hotspot for cooperative behaviour in birds worldwide. They like to stick together with family and mates, in the good Australian way.
Of course, many bird species may readily come to a feeding table and become tame enough to take food from our hand, but this isn’t really “friendship”. However, there is evidence that, remarkably, free-living magpies can forge lasting relationships with people, even without depending on us for food or shelter.
When magpies are permanently ensconced on human property, they are also far less likely to swoop the people who live there. Over 80% of all successfully breeding magpies live near human houses, which means the vast majority of people, in fact, never get swooped. And since magpies can live between 25 and 30 years and are territorial, they can develop lifelong friendships with humans. This bond can extend to trusting certain people around their offspring.
A key reason why friendships with magpies are possible is that we now know that magpies are able to recognise and remember individual human faces for many years. They can learn which nearby humans do not constitute a risk. They will remember someone who was good to them; equally, they remember negative encounters.
Why become friends?
Magpies that actively form friendships with people make this investment (from their point of view) for good reason. Properties suitable for magpies are hard to come by and the competition is fierce. Most magpies will not secure a territory – let alone breed – until they are at least five years old. In fact, only about 14% of adult magpies ever succeed in breeding. And based on extensive magpie population research conducted by R. Carrick in the 1970s, even if they breed successfully every single year, they may successfully raise only seven to eleven chicks to adulthood and breeding in a lifetime. There is a lot at stake with every magpie clutch.
The difference between simply not swooping someone and a real friendship manifests in several ways. When magpies have formed an attachment they will often show their trust, for example, by formally introducing their offspring. They may allow their chicks to play near people, not fly away when a resident human is approaching, and actually approach or roost near a human.
In rare cases, they may even join in human activity. For example, magpies have helped me garden by walking in parallel to my weeding activity and displacing soil as I did. One magpie always perched on my kitchen window sill, looking in and watching my every move.
On one extraordinary occasion, an adult female magpie gingerly entered my house on foot, and hopped over to my desk where I was sitting. She watched me type on the keyboard and even looked at the screen. I had to get up to take a phone call and when I returned, the magpie had taken up a position at my keyboard, pecked the keys gently and then looked at the “results” on screen.
The bird was curious about everything I did. She also wanted to play with me and found my shoelaces particularly attractive, pulling them and then running away a little only to return for another go.
Importantly, it was the bird (not hand-raised but a free-living adult female) that had begun to take the initiative and had chosen to socially interact and such behaviour, as research has shown particularly in primates, is affiliative and part of the basis of social bonds and friendships.
If magpies can be so good with humans how can one explain their swooping at people (even if it is only for a few weeks in the year)? It’s worth bearing in mind that swooping magpies (invariably males on guard duty) do not act in aggression or anger but as nest defenders. The strategy they choose is based on risk assessment.
A risk is posed by someone who is unknown and was not present at the time of nest building, which unfortunately is often the case in public places and parks. That person is then classified as a territorial intruder and thus a potential risk to its brood. At this point the male guarding the brooding female is obliged to perform a warning swoop, literally asking a person to step away from the nest area.
If warnings are ignored, the adult male may try to conduct a near contact swoop aimed at the head (the magpie can break its own neck if it makes contact, so it is a strategy of last resort only). Magpie swooping is generally a defensive action taken when someone unknown approaches who the magpie believes intends harm. It is not an arbitrary attack.
When I was swooped for the first time in a public place I slowly walked over to the other side of the road. Importantly, I allowed the male to study my face and appearance from a safe distance so he could remember me in future, a useful strategy since we now know that magpies remember human faces. Taking a piece of mince or taking a wide berth around the magpies nest may eventually convince the nervous magpie that he does not need to deter this individual anymore because she or he poses little or no risk, and who knows, may even become a friend in future.
A sure way of escalating conflict is to fence them with an umbrella or any other device, or to run away at high speed. This human approach may well confirm for the magpie that the person concerned is dangerous and needs to be fought with every available strategy.
In dealing with magpies, as in global politics, de-escalating a perceived conflict is usually the best strategy.
There are two kinds of solidarity. Exclusive solidarity is essentially protectionism. Groups rally to stand up for their own kind and do each other favors such as recommend each other and give each other jobs. It exists on the basis of what divides us, what makes us different from others.
Birds do this too. If you are observant and like being outdoors, for instance go for walks, you may on occasion have seen crows appearing from all sides and forming a circle around a crow attacked by someone’s dog. You can also occasionally hear a lot of loud cackling, look up and see a group of magpies around a cat that has climbed into a tree.
Inclusive solidarity, on the other hand, is much closer to compassion. It does not ask many questions and exists on the basis of what we have in common.
Birds do this as well. If for example you happen to have lived with certain parrots, you may be quite familiar with this. I adopted two quaker parrots in 1994 and they both stood up for my cats if they thought some harm might be happening to one of my cats, for example if I had to stuff a pill into a cat’s mouth and make sure the cat swallowed it, for a very good reason. This happened regardless of whether the cat in question was kind to birds or not.
Birds are capable of compassion because they appear to have something called “theory of mind” just like humans do.
I have seen one of my little parrots quickly step forward and snatch a bit of feces off the other bird. It was stuck to a feather. That other bird never even noticed what happened. This was an act of selfless compassion based on the first bird’s reasoning that she would not want to have feces stuck to her own butt and therefore the other bird probably wouldn’t like it either.
I have two kinds of confirmation for this.
In the past, I have seen that particular bird come running down a series of perches (in a huge cage) and then stop short to avoid stepping into fresh feces.
This particular bird was a pretty intelligent rascal who went through phases of pranks involving feces. For a while, she took great delight in pressing her butt against the bars of the open cage to help her aim and then pelt poop at my shoes whenever I sat reading in a chair near the cage, for example. Poopball. Goal! This means that the bird assumed that I would not like getting feces on me and also that she knew that getting feces on my shoes wasn’t so bad.
This bird has forever changed the way I look at birds. I used to see birds as completely devoid of anything resembling human intelligence. Birds flew, hopped and tweeted. That was it. Oh, and they laid eggs, too. Particularly the flying made me experience them as distant, I presume. Removed. Different.
I couldn’t have been more wrong about that.
I still remember the look that parrot – the longest-living of the two – gave me when I apologized to her for it having taken me so long to realize how intelligent she was. How stupid the two of them must have thought we humans were and how desperate they must have felt at times. “Is she ever going to get it?” She was a very wise one, that one. (She started showing me, by anticipating my moves and wishes and acting on them, all by herself. The first time that happened I was stunned.)
We’d all do ourselves a favor if we could focus more on inclusive solidarity and less on protectionism. I believe we’re slowly getting there.
