Often found along streams, treefall gaps, and secondary growth where cover is thick. Typically keeps within a few meters of the ground but may range into the midstory where vegetation is dense.

Useful to know

Often placed with the gnatcatchers, this tiny understory skulk was long treated as part of the Long-billed Gnatwren complex before being split mainly on vocal differences. Its rapid, chattering song gives the species its English name and is the best clue to identification. It moves methodically through vine tangles with its very long tail often cocked and fanned.
