Moles are digging, Woolly Bears are emerging and preparing to pupate and develop into Isabella Tiger Moths, and Painted Turtles are emerging and warming their cool bodies by basking in the sun. Red-winged Blackbirds, Killdeer and Wood Ducks are back. Silver Maple buds are beginning to swell. Ticks are out and about. New signs of spring are appearing on a daily basis, and those of us who keep nature journals are busy recording our discoveries. These events may happen every year, but they never get old.
Studies based on the records that Henry David Thoreau and other naturalists kept for Concord, MA in the middle of the 19th century have found that the flowering of plants, leaf-out, butterfly emergence and the arrivals of some migratory birds are occurring earlier now than they did 165 years ago — anywhere from a day to three weeks earlier depending on the species — driven mostly by warmer spring temperatures. Since the mid-1800’s Concord has lost roughly a quarter of its wildflowers while an additional third have become rare.
Whether it be through a written journal, sketches, photographs, videos or taped voice recordings, the observations we make today are a valuable resource for phenology (the timing of biological events) and climate change studies and for our own personal histories of natural places we visit year after year. We are so fortunate that the current state of the world doesn’t prevent our appreciation of and participation in this annual spring ritual.
