Useful to know

A small Andean wren of mossy cloud forests, it forages nimbly through bromeliads and dense understory with its tail often held cocked. Its rich, musical series of whistles and trills carries far and is a key clue to its presence in foggy, high-elevation habitats. It is largely insectivorous and helps control arthropod populations. Typically seen in pairs that defend territories year-round.
