Useful to know

The western grasswren is a shy, ground-oriented malurid that slips through dense shrubs rather than flying long distances. It often forages as a pair, giving soft contact calls and occasional duets. Its long, graduated tail is frequently held cocked, aiding balance while moving through thick cover. Habitat degradation and introduced predators have impacted some local populations.
