Stan’s Notes: This is the only warbler that moves headfirst down tree trunks. Look for it searching for insect eggs in the bark of large trees. Its song sounds like a slowly turning, squeaky wheel going round and round. Female performs a distraction dance to draw predators away from the nest. Constructs its nest on the ground, concealing it under dead leaves or at the base of a tree. Found in a variety of habitats.
