In the cool, leaf-layered forests of North America, this living stripe creeps along trunks and branches with restless focus. It hunts insects hidden in bark and curled leaves, moving more like a nuthatch than a typical warbler as it traces every groove. What makes it extraordinary is its quiet service to the woods — by clearing trees of harmful insects and linking forest patches through migration, it helps keep woodland ecosystems resilient. A flash of contrast in constant motion, yet a tireless caretaker of the trees.
