Colors of Fright, Beauty, and More
by Naturalist, Martha Cerda
October has come to represent a time where nature bursts of beauty. Where transformations in our landscape scream “CHANGE, CHANGE, CHANGE!” before our eyes. The month is also rich in traditions, with the 31st of the month being a day celebrated by many. Throughout the month all hues of orange colors linger in our minds and homes for weeks. A symbol of fall and traditions, tints of orange are linked to pumpkins, fall, and the dreamy tone of our afternoon skies.
During this time of year, the colors of nature are breathtaking. These colors manage to make us feel all the feelings. From warmth and cozy to fiery and alarmed. British poet Leigh Hunt once wrote, “Colors are the smiles of nature.” Nature smiles at us quite often, but it is often during seasonal changes that we can see a cluster of colors be more prevalent than others. Beyond a smile, orange tones across wildlife can be warnings or mere displays of beauty. This vibrant color can range from dark to light across wildlife and often screams, “STAY AWAY FROM ME, PROCEED AT YOUR OWN RISK, BUT ALSO REMEMBER ME.”
Coloration is important in all kingdoms of life. Specific colors aid in camouflaging or blending in with surroundings. Bright colors can be perceived as threatening and toxic, representing a clear message of caution. This is called warning coloration, basically it is nature letting us know to stay away for our own good. Contrasting and alternating colors can follow with a sting, bite, or bad aftertaste. But not all bright colors indicate danger. Bright hues can also represent beauty. Across bird species colors are closely tied with wooing a mate. Males tend to be more brightly colored (not always though) than females in order to sweep the female off her claws for a season or perhaps lifetime. Bright plumage coloration in male birds might not signal danger, but it is a way of competing for the ultimate goal, survival. Vivid colors across nature can also be influenced by chemical processes and environmental conditions including (but not limited) to temperature, light, and nutrition.
Animals, plants, fungi, and other organisms are no strangers to the color orange. Many not afraid to let their colors shine. Each express a tint of this effervescent color in a unique and different way. Their vivid color expression can be seen as a lively smile from nature. This fall season find the following Pleasanton and Bay area residents that sport the color orange. Please remember to be careful and mindful of the spaces you visit and the wildlife you encounter.
