The Carpentarian grasswren is a species of bird in the family Maluridae. It is endemic to Australia.
Region
Northern Australia (Gulf of Carpentaria region)
Typical Environment
Occurs patchily on sandstone and quartzite ranges and rocky hills in the Gulf Country of northwest Queensland and the adjacent Northern Territory. It favors areas with dense, mature spinifex interspersed with rocks, sparse shrubs, and scattered eucalypts. Territories are often isolated by unsuitable lowland habitats, creating natural fragmentation. Fire history strongly influences occupancy, with birds preferring long-unburnt spinifex. Human-induced changes to burning patterns can reduce available habitat.
Altitude Range
0–500 m
Climate Zone

Ease of Keeping
Beginner friendly: 1/5
This elusive grasswren of the family Maluridae is confined to the rocky, spinifex-covered ranges fringing the Gulf of Carpentaria in northern Australia. It depends on mature Triodia (spinifex) hummocks for nesting and cover, making it sensitive to frequent or extensive fires. Birds usually keep low and run mouse-like between clumps, flashing a rufous tail. Habitat fragmentation and altered fire regimes are key threats.
Temperament
skulking and territorial
Flight Pattern
short rapid wingbeats; reluctant, low, and brief flights
Social Behavior
Typically found in pairs or family groups holding well-defined territories year-round. Monogamous pairs nest low within dense spinifex hummocks, usually laying small clutches. Young may linger with parents for a time before dispersing to nearby suitable patches.
Migratory Pattern
Resident
Song Description
A soft, tinkling series of trills and whistles delivered from within cover or a low perch. Pairs often duet, and contact calls include sharp chips and scolds when disturbed.
