About This Species

A small, active songbird of open woodland and scrub, constantly flicking its long tail from side to side while gleaning insects from foliage in the mid and upper canopy. Its thin, wheezy call and near-constant motion are usually the first clues to its presence, since the pale grey plumage blends easily into dappled light. Spring, when males sing persistently to establish territory in deciduous and mixed woodland edges, is the easiest time to track one down.

Ethical Viewing Guidelines

  • This species tolerates observation reasonably well if you stay still and let it move through the canopy rather than following directly beneath the nest tree, since nests are small, well hidden and easily disturbed early in the season.
  • A slow approach and pausing periodically to watch rather than press closer will keep stress to a minimum.
  • General park and reserve rules against approaching active nests apply regardless of location.
