- Amytornis modestus
Identification
Dull greyish-brown, fine, dark-edged whitish streaks, paler underparts.
Distribution
Taxonomy
Formerly considered conspecific with Western Grasswren; see also Birdforum discussion[5].
Subspecies[1]
Seven subspecies recognized:
- A. m. modestus formerly in central Australia (southern Northern Territory), last reported 1936
- A. m. indulkanna in western Lake Eyre Basin, south central Australia
- A. m. cowarie in northeastern South Australia (southern Sturt Stony Desert)
- A. m. raglessi in western Lake Eyre Basin, south central Australia
- A. m. curnamona in east central South Australia (southwestern Lake Frome Basin)
- A. m. obscurior in southeastern Australia (Grey Range periphery, northwestern New South Wales)
- A. m. inexpectatus formerly southwestern and north central New South Wales, last reported 1898
Habitat
Thick bushes and shrubby vegetation. Particularly acacia-dominated shrublands, dense shrub associations in drainage depressions, and Triodia spinifex with acacia shrubland components.
Behaviour
Diet
The diet consists of a wide variety of insects, from termites, to spiders, also caterpillars, grass seeds and small berries.
Diet
The female builds a hooded, deep, cup-shaped nest formed from strips of bark and dry grass, lined with fine dry grass and sometimes flowers or feathers. The 1-4 eggs are laid at 40-48 hour intervals. Both sexes incubate the eggs for 15-17 days, and feed the young.
