Migratory Birds Feel the Heat
By Elizabeth Carroll, C2ST Intern, Loyola University
Upon the long-awaited onset of spring, a thawing Midwest greets millions of migratory birds as they return for the northern hemisphere’s warm season. The soft calls of songbirds and the less pleasant honks of Canada Geese replace our alarm clocks as a reminder of the warm weather to come. But a bird’s migration is no small task, even for the toughest and most resilient species. Traveling from wintering grounds to breeding grounds can be a several thousand mile journey teeming with a wide variety of predators, perilous weather, and unpredictable resource availability. Threats of climate change throughout their migration routes amplify birds’ vulnerability to these dangers.
