Once the misery of winter fades, warblers burst onto the scene like a rainbow after the clouds. These pint-size songbirds pass through our parks, yards, and forests on their way north to their breeding grounds. They visit us in the fall, too, when they’re working their way south, but many of the males sport drab plumage and skulk in the shadows then. In the spring, though, they've molted into their flashiest feathers, so they strut out onto a catwalk of branches and sing their hearts out. You’ll find that it’s easier to identify them now—and even easier to become a warbler fanatic. To see spring warblers, grab a pair of binoculars and choose a place with trees of various sizes and, if possible, a water feature. Then search high and low. Some species scurry along the ground, some forage in the canopy, and some creep along branches and trunks. Try learning to identify a few songs; you’ll often hear warblers before you see them. Your reward for all of this searching...
