Early ornithologists called this species the Black-and-White Creeper or Creeping Warbler. Constantly in motion, in searches for insects on bark, moving along head up like a creeper or down like a nuthatch. It has a brisk, sibilant song, usually a string of high-pitched double syllables—weesee, weesee, weesee, weesee.
