In the winter my yard is quiet, almost too quiet. I’ll find that I tend to turn on music or hum more during those dark months. Perhaps I hum more because I miss the sound of constant summer songs that seem to emanate from the trees themselves? Humans sing to their children, with each other, and to themselves much like birds do. Is there a correlation between the bird’s brain and ours?
Studies of the mockingbird have shown that there could be. Ornithologists have found that mockingbird species living in unpredictable climates, such as a desert, tend have more elaborate songs than those living in more stable climates. Songs are used to attract mates; a mockingbird has the unique ability to create, copy and “make up” variations of songs. It’s believed the female may choose a male based on the differences in his song, interpreting it as a sign of strength and intelligence. This is highly relevant to human behavior because some believe there is a connection between the development of the bird’s brain and our own. Human displays of language, the arts and music might have evolved through a similar process.
As I was considering the social pressures that might have caused the mockingbird to over perform, somehow my “bird brain” made the connection with humans surviving in unpredictable climates, and the artistic outcomes of those experiences. My mind wondered through the planets “hot spots” marveling at Russian painters, Polish pottery, hand painted beads of Ghana, and the woven fabrics of Peru. Just like I would sing to myself more often in the winter, the cultures that live in harsh conditions tend to have a more colorful lifestyle. Different levels of expression, but expression none the less.
Living in the desert city of Tucson, Arizona for example, I loved the painted freeways. What an unexpected surprise! Instead of a drab cement grey the corridors are painted pleasant colors of purple, peach, yellow, red and green. I also noticed a breath of life in the talavera pottery, jewelry, traditional clothing, and home décor. Could cultures that developed in unpredictable climates develop a richer more colorful environment? It seems that way. This summer I view the song birds with a new eye and ear. Is that a flock of Chickadees in the tree or a mariachi band? Either way it’s the sound of life!
