Monarch butterflies are hard to miss with their brilliant orange color and a wingspan that can reach four inches across. But recently they've been difficult to find because their numbers are in decline.
In this edition of Outdoor Radio, biologists Sara Zahendra and Kent McFarland track Monarchs in the flower-filled fields of the Burlington Intervale. We'll learn how Monarchs migrate to Mexico and the challenges to their survival.
"There's a lot of different butterflies here. There are 105 different species of butterflies in Vermont," says McFarland. "And we're after one of them."
