Chestnut-breasted Whiteface (Aphelocephala pectoralis)

The Chestnut-breasted Whiteface is a small, quiet ground-foraging bird of arid and semi-arid inland Australia. On clearing and construction sites, protect low chenopod shrubland, especially Low Bluebush, because the species is difficult to detect and is listed as Rare in South Australia under the National Parks and Wildlife Act 1972.

Conservation status

South Australia, National Parks and Wildlife Act 1972: Rare.

Breeding season

The Chestnut-breasted Whiteface is a resident bird, but its breeding calendar is poorly documented. Breeding is likely to vary between years and regions, and may be linked to local rainfall and food availability rather than fixed months.

Breeding mode: Breeds as pairs. No breeding colonies are described.

Nest site: Bulky, dome-shaped nests are built in bushes, usually Low Bluebush, with a side entrance and feather or wool lining.

Clutch size: Usually two eggs. A clutch of two to three eggs has also been reported.

Incubation: Not recorded.

Fledging and dependence: Nestlings are altricial and remain in the nest while fed by their parents. Fledging timing is not recorded.

Age at maturity: Not recorded.

Breeding frequency: Not recorded. Breeding may be opportunistic when local conditions are suitable.

Timing may shift between regions and years, especially with rainfall, food supply and shrub condition, so pre-clearance checks should allow for active nests in any season.

  • Breeding and nesting: No reliable breeding months are established, so active nests should be considered possible in any month, particularly after suitable rainfall.
  • Eggs and nestlings: Eggs or dependent nestlings may occur whenever breeding is underway, with nests most likely to be concealed in Low Bluebush and other low shrubs.
  • Resident presence and ground activity: The species is treated as resident in Australia and forages on the ground in pairs, small groups or mixed flocks throughout the year.
  • Detectability and local movements: Detection can be poor in any month because the birds are quiet, cryptic and may fly low into shrubs or across stony ground when disturbed.
  • Highest clearing risk: Clearing risk is year-round because breeding timing is not defined, nests are in shrubs, and birds may be difficult to detect before disturbance.

Identification: Appearance

The Chestnut-breasted Whiteface is small, rounded and relatively quiet. It is easily overlooked against stony ground and low shrubland, so spotters should check flushed birds carefully.

The bird is about 10 cm long and has a short, black, finch-like bill. The upperparts are warm brown to grey brown, with dark grey to brown wings and tail.

Look for the broad chestnut band across the breast. The face, throat and lower forehead are whitish, the belly is white, and the flanks have reddish-brown markings. The eyes are usually buff white. The legs are black.

  • Rounded, robust body shape.
  • Broad chestnut breast band in all plumages.
  • White face and underparts.
  • Reddish-brown markings on the flanks.
  • Black tail with a broad white tip.

Identification: Calls and similar species

The species is relatively quiet while feeding. Calls include a soft, twittering sound and a repeated, medium-pitched trill.

It can occur with Banded Whitefaces, Southern Whitefaces, wrens and Cinnamon Quail-thrushes. The chestnut breast band is the most useful feature for separating it from other whitefaces.

Identification: Behaviour and field signs

Birds usually feed on the ground in pairs or small groups. When disturbed, they fly close to the ground in a low, undulating flight, then drop into a low bush or onto stony ground.

There are no distinctive droppings, whitewash marks, stains or odours that can be relied on for site detection. Nests are bulky domes with a side entrance and may be visible in Low Bluebush.

  • Search beneath and between low shrubs, not only in open gibber.
  • Watch the landing point after a flush, as the bird may remain close to the ground.
  • Listen for soft twittering from mixed flocks.
  • Do not assume that a quiet or empty shrubland patch is unoccupied.

Distribution: Australian range

The Chestnut-breasted Whiteface is primarily an inland Australian bird of arid and semi-arid country. Records and mapping should be checked closely because the species is poorly detected and some records outside South Australia are uncertain.

The established range is inland South Australia, including stony desert country from around Coober Pedy and Tarcoola through the Marla and Oodnadatta area, and south-east towards Marree, the Birdsville Track and Leigh Creek districts.

Project mapping identifies records or mapped occurrence in the Northern Territory, South Australia and Victoria. The available species account describes the bird as endemic to South Australia, with some Northern Territory sightings unconfirmed. Any Victorian or Northern Territory record should be checked against the original observation and identification details.

  • Arid central and north-eastern South Australia.
  • Stony plains, tablelands, hills, breakaways and rises.
  • Some former areas are no longer occupied following habitat degradation.

Distribution: Site assessment

Treat suitable shrubland as potential habitat even when recent records are absent. The species can be difficult to detect, and birds may be present in low numbers or move away before a survey team reaches them.

  • Review nearby records before clearing or construction.
  • Map intact Low Bluebush and other perennial chenopod shrubland.
  • Record flushed birds, calls, flock associations and the habitat where they land.
  • Keep the observation location and direction of movement in the field notes.

Distribution: Overseas range

The Chestnut-breasted Whiteface is restricted to Australia. No overseas range is recognised.

Habitat: Landforms and vegetation

Look for the species in open, stony country with scattered perennial shrubs. Low Bluebush and other chenopod shrubs provide cover, feeding areas and nesting opportunities.

Typical habitat includes elevated stony plains, gibber tablelands, stony hills, breakaways and low rises associated with stony plains. Vegetation is usually low and open, with bluebush, saltbush and sparse grasses.

Preferred habitat is chenopod shrubland containing Low Bluebush, Maireana astrotricha. Other useful shrubs may include Atriplex, Sclerolaena, Rhagodia and Eremophila.

  • Intact low perennial shrub cover.
  • Stony ground with shrubs close enough to provide escape cover.
  • Shrubland with open ground between plants for feeding.
  • Areas where shrubs have not been removed by grazing, mining or fire.

Habitat: Habitat condition

Very bare gibber with little undergrowth is less likely to support the species. Assess the remaining shrub layer, including scattered plants around the edge of tracks, pads and disturbed areas.

  • Map living Low Bluebush and other perennial shrubs before disturbance.
  • Check whether grazing has reduced shrub height, density or regeneration.
  • Include habitat on the margins of proposed access tracks and work areas.
  • Avoid treating sparsely vegetated country as having no fauna value.

Foraging habitat: Foraging areas

The Chestnut-breasted Whiteface feeds mainly on the ground among stones and low shrubs. It takes seeds and insects, and may also catch insects in short flights.

Search open ground beneath and between low chenopod shrubs, especially where perennial cover remains scattered across stony plains and rises.

The species may perch in low shrubs and then return to the ground. It can also hawk insects briefly from a low perch.

  • Stony ground with nearby Low Bluebush.
  • Open shrubland with sparse grasses.
  • Areas supporting seed-producing grasses and herbs.
  • Shrub edges and small open patches within chenopod cover.

Foraging habitat: Food

Recorded foods include beetles, moth and butterfly larvae, wasps, grasshoppers and shield bugs. Seeds include arid grasses such as Panicum and Setaria, as well as seeds from Sida and Portulaca.

Feeding method: Mostly ground foraging, with occasional short flights to catch insects.

Social behaviour: Usually feeds in pairs or small flocks, sometimes with other whitefaces or Cinnamon Quail-thrushes.

Foraging habitat: Field approach

Walk slowly and scan the ground and shrub bases. Avoid relying only on call playback or visual searches from a vehicle. If birds flush, follow the flight path and inspect the landing area without chasing them through the shrub layer.

  • Use quiet approaches and pause often to scan for movement.
  • Check mixed flocks carefully for the chestnut breast band.
  • Record feeding habitat separately from the nearest nest or sheltering shrub.
  • Suspend work briefly if a bird repeatedly returns to a small shrub patch.

Breeding habitat: Nest and nest site

The species nests in low shrubs, usually Low Bluebush. Nesting timing is not well documented, so suitable shrubs should be treated as potential breeding habitat whenever they occur within a work area.

The nest is a bulky, dome-shaped structure made from twigs. It has a side entrance and is lined with feathers, fine material or sheep wool. Nests are usually built in Low Bluebush.

A nest may be concealed within the shrub and can be missed during a quick visual inspection. Do not pull apart shrubs during pre-clearance searches.

Typical clutch: 2 to 3 eggs.

  • Inspect Low Bluebush from several angles.
  • Look for a dome shape, side entrance and fine lining material.
  • Check shrubs along the edge of pads, tracks and clearing boundaries.
  • Mark any suspected nest and keep people and machinery away until it has been assessed.

Breeding habitat: Breeding response

Breeding months, incubation period and fledging period are not established in the available field account. Use a precautionary approach where adults repeatedly enter a shrub, carry nesting material or show alarm behaviour.

  • Stop work around a suspected active nest.
  • Notify the site ecologist or fauna manager.
  • Avoid clearing adjoining shrubs until the nest status and work controls are confirmed.
  • Record adult behaviour, nest location and the proposed disturbance footprint.

Breeding habitat: Pre-clearance checks

A competent fauna spotter catcher should inspect suitable shrubs before clearing. Searches should be slow and close enough to identify concealed dome nests, while avoiding unnecessary disturbance.

  • Map all suitable shrub patches before machinery arrives.
  • Use a staged clearing approach where practical, leaving escape cover connected to surrounding habitat.
  • Recheck shrubs if clearing is delayed or conditions change.
  • Do not relocate a nest or bird unless directed by the relevant wildlife authority and project ecologist.

Sheltering habitat: Escape cover

Low shrubs and stony ground provide cover when birds are disturbed. The species has no known specialised roost structure, so retain a connected layer of low perennial vegetation.

After flushing, birds commonly fly low to a nearby bush or land on stony ground where their colour provides camouflage. Low Bluebush and other scattered perennial shrubs are therefore useful shelter even when no nest is present.

  • Retain shrubs beside work areas where possible.
  • Keep escape routes open between shrub patches and adjacent habitat.
  • Avoid driving through low shrub cover during fauna handling.
  • Check beneath shrubs and around rocks before moving machinery or materials.

Sheltering habitat: Roosting

Specific roost sites and communal roosts have not been identified. For site management, assume that low shrubs and nearby stony ground may be used for short-term shelter or resting.

  • Limit night work and vehicle movement through intact shrubland where practicable.
  • Use lighting that is directed away from retained habitat.
  • Keep stock, rabbits and earthmoving activity out of retained shrub patches.
  • Do not remove isolated shrubs simply because no bird is seen in them.

Sheltering habitat: Handling flushed birds

The species may fly only a short distance, or may travel far enough to make relocation difficult. Allow naturally mobile birds to leave the disturbance area before clearing proceeds, and keep machinery stopped while a bird is moving through the work zone.

  • Track the bird visually to its landing point.
  • Give the bird time to settle before resuming work.
  • Use a qualified fauna handler if an injured, trapped or immobile bird is found.
  • Record all fauna interactions in the daily clearing log.

Threats: Clearing and construction

The main risks on works sites are loss of perennial shrub cover, direct mortality during clearing and habitat degradation around mining and access infrastructure. The species is listed as Rare in South Australia, so avoidable impacts should be reduced at the planning stage.

Vegetation removal can destroy feeding, sheltering and nesting habitat. Birds may also be killed if they remain hidden in shrubs or are unable to move away from machinery.

  • Clearly mark the approved clearing boundary.
  • Retain Low Bluebush and other perennial shrubs wherever the design allows.
  • Use pre-clearance searches and staged clearing.
  • Stop work if an active nest, injured bird or trapped bird is found.

Threats: Mining, tracks and fragmentation

Opal mining and exploration can remove or degrade suitable habitat. New tracks, pads and service corridors can also fragment low shrubland and increase vehicle access.

  • Use existing tracks and previously disturbed areas where practicable.
  • Keep temporary work areas within approved footprints.
  • Avoid isolated Low Bluebush patches and intact shrubland on stony rises.
  • Rehabilitate disturbed ground with locally appropriate perennial shrub species.

Threats: Grazing and rabbits

Rabbits and livestock can reduce or remove the low perennial shrubs on which the species depends. Loss of Low Bluebush reduces cover and nesting opportunities.

  • Control rabbits around retained habitat where authorised.
  • Exclude stock from rehabilitation areas until shrubs are established.
  • Protect shrub regeneration from grazing and vehicle damage.
  • Monitor retained and rehabilitated shrub patches for ongoing loss.

Threats: Fire, weeds and site operations

Changed fire patterns can reduce food and shrub cover. Weeds, dust, spills, altered drainage and vehicle strikes can add pressure around construction areas.

  • Include fire, weed and pest controls in the site environmental plan.
  • Keep vehicles to designated routes and enforce low-speed rules where fauna is active.
  • Prevent dust, fuel and chemical impacts on retained shrubland.
  • Continue fauna and habitat monitoring after clearing and during rehabilitation.

Survey methodology: 1. Desktop assessment

The Chestnut-breasted Whiteface is a small, quiet ground-foraging bird that can be hard to detect against stony ground. Treat suitable chenopod shrubland and Low Bluebush as potential habitat, even where birds are not seen during one visit.

Map elevated stony plains, gibber tablelands, stony hills, breakaways, rises and open chenopod shrubland before field work starts.

Identify Low Bluebush, saltbush and other perennial shrubs that could provide cover, foraging habitat or nesting sites.

Check recent records, historical records, land condition, rabbit and stock grazing pressure, opal mining, exploration, fire history and proposed clearing footprints.

Confirm the current conservation listing and approval pathway for the project location. Treat the species as a rare species in South Australia and apply the relevant level of survey and impact assessment.

Survey methodology: 2. Field detection

Survey on foot through suitable shrubland and stony habitat. Walk slowly and scan the ground, shrub bases and low shrubs.

Watch for pairs, small groups and mixed flocks containing other whitefaces, wrens or Cinnamon Quail-thrushes.

Listen for the soft twittering call and other repeated twittering or trilling calls, but do not rely on calls alone.

Use an experienced observer who can separate the Chestnut-breasted Whiteface from Banded Whiteface and Southern Whiteface. Confirm records with clear photographs, field notes or an agreed expert verification process where possible.

Survey methodology: 3. Timing and effort

Plan surveys in daylight and in calm conditions when birds are likely to forage on the ground. Avoid relying on a single short visit.

Repeat searches where habitat is suitable, particularly if the first survey occurs during dry conditions, when detection may be low.

Use several visits where clearing is extensive, habitat is continuous or the species is a reasonable likelihood of occurrence. Set the number and spacing of visits through a qualified ecologist and the approval authority.

There are no established migration periods or universal survey months for this species. Select survey timing around local conditions, recent rainfall, vegetation condition and the proposed disturbance schedule.

Survey methodology: 4. Records and reporting

Record the date, start and finish time, observers, weather, recent rainfall if known, route, search effort, habitat condition and survey limitations.

Map every detection, flock, flight path, feeding area, low shrub refuge and potential nest shrub. Record whether the bird was on the ground, in a shrub or in flight.

Describe the habitat, including shrub species, density, height and signs of grazing, rabbits, fire, mining or other disturbance.

Photograph habitat and diagnostic features where this can be done without chasing or repeatedly flushing birds. Report non-detections with the effort and conditions, not simply as absence.

Before habitat disturbance: 1. Avoidance and approvals

Avoiding habitat is the first measure for this rare species. Plan clearing around retained shrub cover and obtain the required approvals before any vegetation disturbance begins.

Redesign the footprint to retain elevated stony habitat, Low Bluebush and other perennial shrub cover wherever practicable.

Confirm whether the proposed action could affect a matter protected under the EPBC Act. Make an EPBC referral where required, and do not assume that a state rare listing alone determines the Commonwealth pathway.

Obtain the relevant state approvals, wildlife permits, native vegetation approvals and land access permissions before clearing. In South Australia, check requirements under the National Parks and Wildlife Act 1972 and other applicable legislation.

If work is proposed in Queensland, obtain advice on the protected wildlife provisions and whether tampering with a breeding place requires a species management program. Obtain any required Queensland SMP before work starts. Confirm equivalent requirements with the relevant agency in the Northern Territory or Victoria where records or potential habitat occur.

Before habitat disturbance: 2. Pre-clearance survey

Complete a targeted pre-clearance search shortly before works. Search all Low Bluebush and other dense shrubs within and beside the disturbance area.

Look for bulky, dome-shaped nests made from twigs, with a side entrance and feather or wool lining. Do not pull shrubs apart or handle a nest during the search.

Search adjoining retained habitat for birds that may move into the work area after disturbance begins.

Mark confirmed birds, active nests, high-quality shrub patches, access routes and no-go areas on the site plan. Have the ecologist update controls if conditions or the footprint change.

Before habitat disturbance: 3. Buffers and exclusion areas

Set exclusion areas around active nests, occupied shrubs, feeding groups and other sensitive habitat identified during the assessment.

Use a clearly marked buffer that prevents machinery, vehicles, personnel and stock from entering. Set the distance case by case with the qualified ecologist and relevant authority because a species-specific standard buffer is not established here.

Keep exclusion areas intact until the ecologist confirms that the risk has passed or the approval authority agrees to a changed control.

Fence or flag retained shrub patches before mobilisation. Protect them from accidental clearing, soil disturbance, dust, fire, weed spread and unauthorised access.

Before habitat disturbance: 4. Timing and induction

There is no confirmed breeding season or migration period to use as a universal clearing window. Schedule works outside periods of highest local breeding activity when local survey information identifies one, and avoid clearing when birds are actively nesting.

Induct all workers, contractors and machinery operators before work. Show photographs of the Chestnut-breasted Whiteface and similar whitefaces, its low flight, low shrub refuge and nest type.

Explain the no-go markings, stop-work process, speed limits, access routes, reporting contacts and injured-animal procedure.

Require the fauna spotter catcher or ecologist to approve the daily work area before vegetation removal starts.

During habitat disturbance: 1. Sequential clearing

Clear habitat in a controlled sequence and give birds time to move away. The fauna spotter catcher must have authority to stop work whenever a bird, nest or other sensitive feature is found.

Clear from the less suitable edge towards retained habitat so birds can move into safe shrub cover rather than becoming isolated.

Remove vegetation in stages and leave escape routes to intact low shrubland. Do not surround a shrub patch with active machinery.

Keep machinery out of marked exclusion areas and use a spotter catcher to inspect each work section before and during clearing.

Pause work during poor visibility, heavy dust, smoke or other conditions that prevent reliable observation.

During habitat disturbance: 2. Stop-work response

Stop work immediately if a Chestnut-breasted Whiteface is found in the clearing area, repeatedly returns to a shrub, shows alarm behaviour or cannot move away safely.

Stop work if a nest, eggs, dependent young or an occupied Low Bluebush is found. Keep people and machinery away and contact the project ecologist and approval authority as required.

Do not chase birds, dismantle nests, move shrubs or block escape routes. Allow the bird to settle and leave naturally where safe.

Reassess the exclusion area, work sequence and approval conditions before restarting. Record the decision and person who authorised the restart.

During habitat disturbance: 3. Handling and injured animals

Only an appropriately authorised and trained person may capture or handle a bird. Do not allow workers to attempt capture.

If capture is necessary, use the least stressful method allowed by the permit and keep handling brief. Place the bird in a secure, ventilated container away from noise, heat and direct sun.

Contact a permitted wildlife carer or wildlife veterinarian for an injured bird. Do not release an injured bird or relocate a healthy bird without ecological and permit advice.

If a nest or dependent young is exposed, protect the site and obtain direction from the qualified ecologist and relevant regulator before any further disturbance.

During habitat disturbance: 4. Daily records

Record all sightings, flushes, nests, injured animals, captures, relocations, stop-work events and clearance areas.

For each record, note the location, time, habitat, behaviour, photographs, action taken, personnel involved and approval or permit reference.

Map the cleared area and retained habitat after each work shift. Report any breach of an exclusion area or unexpected mortality to the site manager and project ecologist immediately.

After habitat disturbance: 1. Completion checks

Post-clearance checks confirm that no animals, nests or unsafe habitat features remain in the work area. Use the results to improve controls for later stages and nearby projects.

Have the fauna spotter catcher or ecologist inspect the cleared area, retained shrub edges, stockpiles, trenches, drains and other fauna traps before the area is handed back to construction.

Check machinery, pipes, spoil piles and temporary structures for trapped or sheltering animals.

Search the edges of retained Low Bluebush and other shrubland for birds displaced by clearing. Record whether birds have moved into retained habitat or nearby cover.

Close or cover trenches and other hazards when unattended, or inspect them at a frequency set by the project ecologist and approval conditions.

After habitat disturbance: 2. Relocated animals and nests

Record the release location, habitat condition, time, method and person responsible for every authorised relocation.

Release healthy birds only where the ecologist and permit conditions support release, using nearby suitable shrub habitat with safe cover and no active machinery.

Do not move an active nest unless specifically authorised. Seek regulator and ecologist direction where clearing affects a breeding place.

Check relocated or released animals where practicable and document their condition and subsequent observations.

After habitat disturbance: 3. Monitoring and reporting

Monitor retained habitat and rehabilitation areas during later construction stages and after major changes in access, fire, grazing, weeds or hydrology.

Use the same mapped locations and comparable search methods where possible. Record detection effort as well as detections.

Report monitoring results, mortality, nest outcomes, habitat loss, weed spread and breaches against the approval conditions.

Submit statutory reports and project completion reports within the required timeframes. Keep field sheets, photographs, maps and permit records with the project environmental register.

After habitat disturbance: 4. Incident review

Review every mortality, nest disturbance, unauthorised clearing event and repeated non-detection with the project ecologist and site supervisor.

Identify whether the cause was survey timing, poor visibility, inadequate marking, equipment failure, crew behaviour or an unsuitable work sequence.

Update the induction, exclusion controls, survey plan and method statement before the next clearing stage.

Notify the relevant authority where required by the approval, permit or incident condition.

Rehabilitation actions: 1. Habitat restoration

Rehabilitation should rebuild open, low shrub habitat rather than simply cover bare ground. The main target is a connected mix of perennial shrubs, including Low Bluebush, with enough ground cover for feeding and shelter.

Retain and protect natural Low Bluebush and other perennial shrubs wherever possible. Natural recovery is preferred to replacing mature shrubs with small plantings.

Rehabilitate stony plains, rises, breakaways and shrubland with locally appropriate chenopod species and native grasses suited to the site.

Use local seed or plant material where available and avoid introducing species that do not belong in the local vegetation community.

Do not spread topsoil, gravel, weeds or wash-down water from infested areas into retained or rehabilitated habitat. Keep rehabilitation areas free from vehicle traffic and unnecessary disturbance.

Rehabilitation actions: 2. Grazing, rabbits, fire and weeds

Exclude or manage stock in rehabilitation areas until shrubs are established and able to withstand grazing.

Control rabbits using approved methods and monitor browsing on Low Bluebush and other perennial shrubs.

Manage weeds before they set seed and remove new infestations from access tracks, laydown areas and rehabilitation sites.

Develop fire controls that protect recovering shrubland and retain suitable food and cover. Avoid broad fire treatment that removes the shrub structure required by the species.

Rehabilitation actions: 3. Breeding and shelter features

Prioritise live shrubs for nesting and shelter. This species builds dome-shaped nests in bushes, usually Low Bluebush, so general-purpose nest boxes are not a direct substitute.

Do not install bat boxes, hollows, caves or communal roost structures for this species. Those features do not match its documented nesting habit.

If suitable shrubs cannot be retained, ask the project ecologist and relevant authority whether an artificial nest structure or other trial measure is justified. Install and monitor it only under an approved species-specific design.

Do not place artificial nest sites where they increase predation, expose birds to machinery or encourage use of unsafe habitat.

Rehabilitation actions: 4. Water, lighting and long-term monitoring

Do not create permanent water points unless they are part of an approved regional restoration design. Manage drainage so rehabilitation receives natural water flows without erosion, ponding or contamination.

Use downward-facing, shielded lighting and switch off unnecessary lights near retained shrubland. Limit glare and night lighting on movement routes and feeding habitat.

Monitor plant survival, shrub recruitment, grazing, rabbits, weeds, fire effects and bird use across rehabilitation areas.

Continue monitoring long enough to show that shrub cover is established and that birds are using the restored habitat. Adjust grazing, rabbit, weed, fire and access controls when monitoring shows decline.
