A Symphony of Birds

Paris is a city of lights, but also a city of sound. The peacefulness of the gardens surrounding the cityscape is no match to the hustle and bustle of everyday city life. Sometimes the sound is welcomed, such as a talented neighbor’s piano playing or an excellent street musician’s violin performance under the Arc de Triomphe. However, sometimes it is less welcomed, such as a taxi honking or an amateur trumpeter interjecting himself on my metro ride. Despite that, I absolutely love the sounds around the city. An overlooked, but equally important aspect to the music of the city, is the music of the animal residents of Paris. Every morning, I walk outside my apartment and generally hear the sound of some animal within five minutes of stepping foot outside my door. Whether it is two pigeons fighting over food by a bakery or two dogs barking as they pass each other, it is clear that animals have specific abilities to communicate unique to each species.

One of my favorite sounds to hear in Paris is the tweeting of birds up in the trees while I walk below on the street. During my time here in Paris, I have been exposed to the knowledge of bird songs in my classes and how their songs act as communication to one another. One questioned asked in class was “If some animals can be shown to have language, do they also create art?”. When I first heard this question, I immediately imagined monkeys holding a paintbrush behind a canvas with paint splattered on it and thought how I wasn’t so sure that it could be considered art. Upon further thinking, I thought of how art can be more than drawing, it could be related to dancing or singing. Instantly I started wondering if some birds may actually be singing for aesthetic purposes or just for their own personal entertainment. I knew that songbirds, like canaries or finches, are even known to have neural circuitry that shows that they are selective in what singing they process from other birds in order to rely on their memories for song learning (Phan et al., 2005). I then began to investigate if birds have been shown to exhibit any capacity of artistic expression and found an article by Gupfinger and Kaltenbrunner (2017) that demonstrated the auditory skills and musical preferences of grey parrots in captivity.

2 What I initially thought of as animals creating art

According to Gupfinger and Kaltenbrunner (2017), grey parrots are quite intelligent and have high audible skills and musical talents. Male parrots are even known to have songs that are specific to only themselves and are able to provide highly trained song learning to their offspring (Berg et al., 2011). The aim of their study was to determine how music and the use of musical instruments would influence the activity of grey parrots and add to their audible enrichment.  A central experiment of the study focused on how the parrots would interact and manipulate a music-producing joystick test device. The parrots’ beaks and legs were able to freely manipulate two joy sticks in two different experimental set ups. The first set up gave one joystick that produced sound and another joystick that remained silent. The preference for the grey parrots to activate the joystick that produced sound over silence demonstrates how parrots are more inclined to have auditory stimulation than to be without it (Gupfinger and Kaltenbrunner, 2017). In the second set up, there were two active joysticks, one set to 90 beats per minute and the other set to 120 beats per minute. This setup was used in order to gain a better understanding of musical and auditory preferences of individual grey parrots. The results from the second setup demonstrate that the parrots preferred to play beats at 90 beats per minute over 120 beats per minute. The spontaneous interaction of the parrots with the joystick device demonstrates that they have a potential capacity to exhibit musical expression.

The real world application of the Gupfinger and Kaltenbrunner (2017) study implies that musical instruments can significantly benefit grey parrots in captivity by giving them a creative outlet for expression. The strength of this experiment was the use of these two different set ups. By being able to compare sound to silence and then strengthen that result (birds prefer auditory stimuli to silence) by specific was measure of beat the grey parrots prefer, it really helps those curious (including me) to agree with their conclusion that grey parrots can not only have vocal singing capabilities, but that they can  consciously process music and have the capability to manipulate a simple form of a musical instrument. While I believe that their experiment, for the most part, was strongly thought through, there is one aspect of their experimental design that I find questionable. Gupfinger and Kaltenbrunner (2017) state that their method to ensure that the birds acknowledged and used the musical joystick was to have a person stay present with the parrots and motivate them to engage with it. This alarms me as a possible confounding variable as they do not go in depth describing what their specific methods were to motivate the birds. The idea to measure grey parrot beat preference and frequency preference proved insightful and begs me to ask the further question of could birds, songbirds and non-songbirds, be shown to have the capability to synthesize the beats that they prefer and make a music all their own?
