Snowball, the Dancing Bird

A video of a dancing bird has become the latest YouTube sensation. Some people thought the bird's performance was faked, but for me, it is not surprising, given the sophisticated ability birds demonstrate for manipulating pitch and rhythm in their songs, that a bird shows the ability to keep time with music. Neuroscientists, including John Iversen of the Neurosciences Institute, have studied the dancing bird and confirm it is capable of extracting a beat from sound.



What impressed me most about Snowball's performance is when he lifts his leg and gives it a little shake before bringing it down. As the investigators mention, it may be prompted by the pace being too fast to put his foot all the way down in time with the faster beat, but it piques my curiosity further. It appears Snowball is dividing the beat when he waves his foot, into two or three little waves, which if I am seeing it correctly, suggests birds are capable of division of the beat and perceiving and manipulating a metrical framework. This is simply astonishing were it be to true, but perhaps not unexpected given the sophistication of bird vocalization and communication. It is one thing for a bird to keep time with a beat and an entirely different for a bird to exhibit division of the beat.

When people sing (or compose a melody to sing) the tones are not of arbitrary duration. No one could sing a song consisting of a series of tones of arbitrary duration measured to fractions of a second. Could you imagine signing a melody: A 1000ms, F 1500ms, E 500ms, D 1000ms, A 1000ms? The human mind is not well suited for measuring duration in milliseconds on an ordinary basis (we can leave out extraordinary abilities some humans may possess or develop). What if someone asked you to pick up the pace to sign faster? Each duration would have to be recalculated down to the millisecond, in your head. For this reason, music is organized by relative measures of duration.

In reality, when people sing or play music, they use simple division of the beat to measure duration. This is usually achieved through the division of a steady beat by whole fractions, usually simple divisors, like two or three. The most basic division of the beat is by two. When a tone of shorter duration than the beat is required, the melody will use a tone one half of the beat, or one quarter or one eighth and so on, down to the ability of humans to resolve divisions of time. The other main division of the beat observed in music is by three. So for every beat you have the possibility of three tones, six tones, twelve tones and so on. The human ability for perceiving and manipulation this time structure is sophisticated. Musicians can anticipate the division of future beats, playing notes that persist across multiple divisions of the beat or create "holes" or silences for certain beats, playing with the listeners expectations (this is called syncopation). I have to wonder if the small movements he makes dividing the beat follow any ornamentation of percussion or melody in the song. In the background, another bird can be seen bobbing his head to the beat, in a clear parallel to human "head banging."

Although I would have to watch a lot more video to be sure, what I have seen suggests he may be dividing the beat and deserves further investigation. I would not be surprised to find that birds do erect a sense of metrical time in sound and can mentally divide the beat and even anticipate it, perhaps even perceive syncopation. It is fascinating to watch Snowball lose and pick up the beat again.

I did watch a couple of video clips. At about 2:00 into the following video he lifts his foot and waves time to the beat, but does not divide it.

In the following video, notice how he keeps the beat when Stevie Nicks sings "ooh, ooh" on the beat? This suggests he has an expectation of the beat even when the beat is not marked by a percussive instrument. At about 1:05 he may have divided the beat with a wave. He does lose the beat more frequently when based only on Nick's vocals or less percussive sections. At 2:31 he appears to divide the beat with a wave again. And at 2:56. I'm not sure if he's just losing the beat or dividing it...but this is a seriously important question about the intelligence of birds. At 4:43 also.

Save the Gulf Branch Nature Center

If you live in Arlington County, please help save Gulf Branch nature center by signing the petition available through Save Gulf Branch Nature Center.

The county is planning to demolish the nature center and leave a parking lot to save a pittance on the budget, totaling $132,057. Our county is blessed with numerous streams and stream valleys rich with wild plants and animals running through the urban landscape. In the 1600s this part of Virginia was described as the finest place in the world to live, with its numerous stream valleys and abundant wildlife set in rolling hills. It would be wrong to lose one of the few points of contact children have with nature. The nature center is an island for the preservation of native species. Moreover, the nature center, due to the proximity of human culture to nature, is an opportunity not found elsewhere to understand humans and their culture are not separate from nature, which could help dispel the destructive urge to recreate a mythic Eden.

I've lived here most of my life and was born in the district and came home to Alcova Heights where my family migrated to when Arlington was Alexandria County. I grew up spending my summers in Alcova Heights park. Doctor's Run, Four Mile Run, Lubber Run and the associated parks were my playground. Long Branch Nature Center was closer to my home, to my neighborhoods of Barcroft and Alcova, so I never visited Gulf Branch, being on the far side of Arlington for me, but through my experience with Long Branch at Carlyn Spring I understand why Gulf Branch should continue.

Biological Construction and Networked Content Creation

The order and symmetry of biologically created structures, such as an egg or the human body, are expressions of how correctly those biological systems worked to construct the natural artifact. Biological organisms are collections of cells cooperating with each other. The order and correctness is an expression of the successfulness of the collaboration.

An egg comes out more egg-like when the biological processed working to make it cooperate and collaborate more correctly in its construction. I believe this has implications for the collaborative processes operating in networked software development and information science. The biological process of construction is inherently different than the one humans have inherited from their tool making and industrial heritage. What will we make of it?

Nature and culture

Nature and culture are connected. Art emerges in nature. I like to photograph the happenstance or "found art" in nature, which is is just another way of saying that art naturally emerges in nature. The potential exists in nature for the creation of art through the juxtaposition of elements according to natural laws and emergent patterns (what we used to think of as chance). This is what I try to capture in my nature photographs.

If you'd like to know more about how nature and culture are connected, read William Cronon's Uncommon Ground.

Notes on Uncommon Ground: The Mythic Eden

Our approach to nature is framed by the narrative where

"...an original pristine nature is lost through some culpable human act..."

"The myth of Eden describes a perfect landscape, a place so benign and beautiful and good that the imperative to preserve or restore it could be questioned only by those who ally themselves with evil."

Echoes the appeal to nature. The similar religious zeal with which science is protected from dissent by accusing those who question prevailing thought as either delusional or malicious. This similar approach to questioning emerges from Enlightenment thinking, ironically, since this is the source of the "question anything" admonition, yet is also the source of dogmatism, once an idea has been baptized as "fact," which can only be questioned by the allies of evil (witness the scientists who say a "new dark age" is threatened by advocates of intelligent design. The imperative becomes hysterical when the prevailing identification with an idea is threatened, the new idea threatens the utopia the person has invested in, whether religious, natural or scientific.

The most popular images in photography, since the middle of the 20th century, are pictures (surrogate realizations) of that perfect, benign and beautiful landscape depicted in the mythic Eden. These are the images of Ansel Adams, which directly contradict the humanist, compassionate, images of the social realists who vociferously rejected his work as a betrayal of their conception of art as a means for bringing about social justice. He may not have thought of it, but perhaps his critics were right, he was unwittingly bending photography to an anti-humanist agenda. One thing is sure, without the emergence of the mythic Eden into the popular consciousness in the post second world war era, his photographs would be obscure, known to only a few collectors. It was with the emergence of the cult of wilderness, centered around an "Edenic narrative" that his photographs gained wider significance. This remains the prevailing wind filling the sales of photography, perhaps it is time the wind changed.

Notes on Uncommon Ground: The Appeal to Nature

"This habit of appealing to nature for moral authority is in large measure a product of the European Enlightenment."

Explains why "science" is used as a non-negotiable trump card against dissenters--one must be delusional, ignorant or malicious to oppose "scientific truth" used as a cudgel by opinion shapers to silence their enemies.

My ideal of nature has always been the one that suits humans, which we have every right and obligation to construct and maintain in order to sustain our existence. This includes the city, which I love, the suburbs, like Arlington with its special character, where I was raised and live and also love, and the country, which I am not so much in love with, but respect and enjoy visiting.

Unfolding the City

It is generally believed that order is preferable to unplanned development. The first villages to emerge with agriculture developed without any plan or structure. In time, people would learn to plan towns on a grid of streets and this became the normal way to develop a town or city, along a rigid grid of streets. But we know better now, after observing the formation of towns for over two hundred years in America, according to city planners, that street plans which emerged organically from the seemingly haphazard choices of many individuals over many years, produce the most efficient street plans which help alleviate and avoid gridlock.

If you look at an English countryside village, you can see how the streets and paths are laid out efficiently to follow the activities of actual people. The preexisting activities and their most efficient paths determine the layout of streets. This also interestingly creates a plan of homes and buildings that people find pleasing, or "picturesque." I believe this is due to the streets and structures following an organic plan, similar to nature and the choices going into the making of the plan represent "chaos" or fractal patterns, which emerge and are made visible in the placement of streets, alleys, and structures giving the town the same pleasing pattern as mountains or other pleasing natural forms. It appears the planned, rigid, rectangular street plans are the least pleasing, the least human scale, the most prone to gridlock, traffic and efficiency problems of movement in the city. Sometimes a controlled randomness, a "natural anarchy" of chaotic processes, organically unfolding the city are preferable to order.

I knew this long before city planners began to discover it. My father before me knew it without understanding why or what it was that made driving Arlington easy. That made it easy to avoid "Rush Hour" so well known to Arlingtonians living so close to the big city and experiencing the daily rush to work and rush to home in the bedroom communities. My father always taught me how he had a dozen different ways to get from here to where we were going. There were always four or five back roads, small arteries, little curving streets that cut off corners, like the maze of arteries and veins in the human leg, there was always a way to get from there to there efficiently without blockage. The organic nature of Arlington's streets was known to him without him ever thinking the world "organic" or describing it in formal town planning terminology. I absorbed this by osmosis riding with him in the family car, and would use this knowledge myself when it came time to drive.

Like the weather, like the soil, the streets of the city are at their best when allowed to unfold organically, understood as complex phenomena, not reduced to simplified models. Neither they way nature works or the way human society works is rational. Although we can understand many things by simplifying nature, reducing it to its constituent parts for analysis, and many beneficial things come from a scientific rational study of nature, in the final analysis nature is irrational. The universe is not ordered like the precise gears of a watch, but ordered in complex, organic ways, like the weather. Rationality is a phenomena of the human mind, a way of comprehending and organizing what it knows about the world and is an imperfect match with reality. It is influenced by the reliance of the human mind on narrative for explaining, organizing, comprehending and remembering the confusing and overwhelming sense perceptions flowing into it continuously from all directions through a number of senses.

The mind as storyteller

Jennifer Armstrong (author, The American Story) said in a talk (BookTv 1/29/07) at the Blue Willow Bookshop, "consciousness moves backwards and forwards in time." I stopped working as my mind dropped into gear and listened as she continued to talk about story telling and history. She had struck a chord in my mind with this observation. I thought how strange it is a thing to say. It seems obvious of course, since we all can move our minds back and forth over the events of our life, consider the future and reflect on the past. But it still struck me as strange.

She followed up her remark with a disclaimer reminding us that at the quantum level time is not very orderly or linear, a thought that occurred to me almost simultaneously with her first remark, a little voice rising against the implied linearity of time. However, the distinction between the mind's comprehension of time and natural time was made clear as was the capacity for the mind to create this construct of linear time in our heads out of the occurrence of events. It is a kind of tape recording of natural time in which we can move time back and forward at will. What gave rise to the strangeness is recognizing the linear conception of time and the ability to move forward and backward in it is a complete fabrication of the mind. We all think of time as obviously linear and fool ourselves into thinking that the time we move our minds back and forth over is the same as the time that exists in the natural world, but the time that exists in our mind is in reality a kind of narrative. I realized there exists a relationship between the mind's ability to move freely backwards and forwards through memory (within essentially a model of natural time) and narrative.

Although I am aware of the debate over the nature of time and that there is an argument that the mind orders time and creates it and that time may not be a physical reality, that what we know of as time is created by the persistence of memory just as a moving picture is created by the persistence of vision, the idea the consciousness moving within time was still striking. Science suggests there may be no "proper order" to the natural world and the linear way in which we perceive events may be an imposition of the mind. It suddenly seemed more important to understand this human view of time than to answer the question what time is in the physical universe, which seemed like a lesser question.

I was struck by the novelty of this idea of the consciousness moving backwards and forwards in time independent of actual time, knowing that one cannot actually move backwards and forwards in time, but the mind can, that it has the power to anticipate and reflect on time. That this storing of natural time as a mental narrative through memory, this ordering of events to comprehend them, is the basis of anecdote (the retelling of a series of events), which is the basis of storytelling. That memory ties in with narrative and natural time.

This reaffirms my belief that stories are the way the mind makes sense of the world, which consists entirely of chaotic sense perceptions. Narrative becomes the basic unit of thought. I believe stories are the way the human mind comprehends and make sense the events and phenomena of the surrounding natural world that come to it through sense perception. I believe storytelling evolved as a way for social animals to explain the world in the only terms they knew, social ones where natural events are caused by willful acts, just as in the social world all occurrences are willful acts of individuals. Storytelling is the most immediate and effective way of ordering and explaining social events. As our consciousness grew more powerful, this mechanism was adapted and extended to explain events of the nature world as willful acts powerful spirits and later people began to separate the events of nature from the supernatural actors, science slowly began to take over the job of telling the story of nature.

It might be said that the mind creates time by ordering events. I would go further than that, that not only does the mind create the ordering of events we know of as time, but that it creates "willful spirits" whose actions explain the events, which become a story. In ancient times, a willful spirit might have been a supernatural being where today the willful spirit may be a conspiracy or some other thing that may rationally be thought to exist. Since we no longer believe in capricious supernatural beings causing natural events, we choose our willful spirits carefully to accord with science and reason. Our mind still looks for the same explanations, we just sugar coat them so they acceptable to a rational society. It is interesting to note that this ability of the consciousness to move backwards and forwards in time arose, science tells us, approximately 50,000 years ago in a small group of humans who began to realize that if they found the tracks of an animal, that it had recently passed and might still be nearby. They could look forward into the future and know that if they followed the tracks they might come across the animal and make it their dinner. We take this ability so much for granted that we do not realize how significant a change this is. It is hardly imaginable, something akin to one of these experiments in simulating disability as part of making the healthy understand disability, what it must be like to not be able to perceive and manipulate time in this way. This underscores how much a part of our mind ordered time and narrative are.

In Haiku, the tree and the person, are not very separated

I was talking with filmmaker Tom Davenport today and the discussion turned to my observations of a tree outside the window of my apartment, which over many years I have observed to display fascinating changes and cycles in response to climate. The conversation turned to haiku as he likened my noticing a leaf falling outside my window on a quiet day to haiku. I was startled when he said "in haiku, the tree and the person are not very separated."

This is an idea very close to Zen. I won't go into the details of Zen belief here, but one idea of Zen is that individuals can reach a state where they feel as if there is no separation between the self and the things making up the world around them. Scientists and Zen masters may debate exactly how and why this feeling arises in the human mind, but what is interesting is the possibility haiku may represent a kind of expression or record of this kind of merging of the individual with things. I found myself agreeing with his observation. He helped me see where the haiku does in a way bring the haiku writer and the tree very nearly together.

The haiku represents the tree very differently than a Western poem might. A poet might say "I sat under a beautiful tree one day..." but a haiku might say "golden tree; a leaf falls; I hear." The haiku tends to describe the subject and the perceptions of the haiku writer, and in so doing the tree becomes less separated from the person and the person a little less separated from the tree. The example is sketchy, but I think it gets to the heart of the difference between the haiku tradition and what is commonly thought of as poetry.

The poem uses the tree as a symbol. The haiku does two very strange things in comparison to the typical poem. It takes a photograph of the tree...in that it describes the tree instead of using an adjective like "beautiful." By describing and naming what is beautiful about the tree, all readers of the haiku can reconstruct the experience of the haiku writer in the same way a photograph reconstructs the scene for which we were not present. The other thing the haiku does is tell use what feeling was evoked by perceiving the tree. In haiku, words represent the tree as itself. Natural events are represented as they happen, and does not try to tell a story. Haiku avoids telling a story.

When it succeeds, poetry is said to communicate what it is like to be alive in the world. In the Western tradition, it achieves this only while sustaining a great deal of separation between the poet and the subject of the poem (the poem tends to deconstruct the tree more than reconstruct it, in that it does not leave the tree alone, but must apply adjectives to it). In the haiku, the writer and the natural phenomena are joined in the act of happening and perceiving, brought together and recorded as if by a camera. The haiku becomes a kind of photographic record of this merging of perceiver and the perceived.

I remembered reading some years ago to avoid adverbs and adjectives in haiku, because they lead to opinions placing things in context, so that by avoiding them "the haiku is left with images of things just as they are." (http://www.ahapoetry.com/haiku.htm 2005) A strong similarity to photography exists in the haiku. I am left to wonder if the photographer and subject are not very much separated once entangled in a photograph, perhaps they do steal men's souls after all.
