Three cuts of song from the same bird as it sat about 2-3m off the ground on various perches. In the first cut the bird would give prolonged twitter series, apparently alarmed by my presence, that it ceased to give when it flew to a branch farther away. Habitat was mixed hemlock/deciduous forest on a steeply sided valley and near a slow river.
