Blue-breasted Quail (Synoicus chinensis)

Conservation status

Victoria, Flora and Fauna Guarantee Act 1988: Endangered.

Breeding season

Wild seasonal timing is not specified in the supplied sources. Captive birds are reported to breed year-round, so the calendar below treats all months as possible breeding and disturbance-risk months rather than identifying a confirmed wild peak.

Confirm local breeding timing from current state records and project surveys before setting seasonal clearing controls.

• Breeding: Captive birds are reported to breed year-round. The timing of breeding in wild Australian birds is not specified.
• Young: Ground nests incubate for about 16 to 19 days, and chicks can fly after about one month. Young may therefore be present in any month if breeding is year-round.
• Highest clearing risk: Treat all months as potential risk months because breeding is reported year-round in captivity and nests are placed on the ground. No wild Australian peak period is provided.

Identification

The Blue-breasted Quail is a tiny, round-bodied quail that usually stays on the ground and may flush from close to a person's feet. It is often detected briefly in dense low vegetation rather than seen in the open.

Adults are 12 to 15 cm long, with a short dark brown tail, black bill and yellow to orange legs and feet.

The male has a dark brown back, slate blue-grey breast, rust to chestnut-red belly, black throat patch, white throat band and black facial markings.

The female is plainer and brown, with a rust-brown breast and belly and a paler underside.

Body size: 12 to 15 cm long

Weight: 20 to 57 g

Leg and foot colour: Yellow to orange

Identification: Similar species

The female can be confused with other small brown quail. The eBird account specifically notes the larger Japanese Quail as a comparison: Japanese Quail has a stronger white brow, while the female Blue-breasted Quail has a plainer face.

The male is more readily identified by its blue-grey breast, cinnamon to chestnut belly and black and white throat pattern.

Identification: Calls and field signs

The male gives a descending, plaintive whistle described as a 'tew-tew' or 'ti-yu'. Other reported sounds include sharp cheeps and a raspy or snoring call, particularly when flushed.

The nest is a ground scrape or hollow lined with dry grass. Eggs are olive green to brown and may have dark brown spots or blotches.

The supplied sources do not describe diagnostic tracks, scats, feathers, eyeshine or sloughs. A quiet flush from dense grass, the reported calls and a small grass-lined ground nest are the most useful field indicators.

• Check dense grass and low vegetation before machinery or hand clearing starts.
• Treat a flushing bird, repeated quail calls or a small grass-lined ground hollow as a trigger for an ecologist or fauna spotter catcher to inspect the area.

Distribution: Australian range

The species has a broad distribution from southern China and South and Southeast Asia through New Guinea and northern Australia to south-eastern Australia. The supplied sources do not provide Australian population estimates, trends, strongholds or mapped bioregion records.

The Blue-breasted Quail is recorded in New South Wales, the Northern Territory, Queensland, South Australia, Victoria and Western Australia.

The supplied information does not identify particular Australian bioregions, local strongholds or discrete subpopulations. Project assessments should therefore rely on current state databases, local records and targeted field surveys.

Australian states and territory listed: New South Wales, Northern Territory, Queensland, South Australia, Victoria and Western Australia

Australian bioregions: Not specified in the supplied sources

Population size and trend: Not provided in the supplied sources

• Search state and territory biodiversity databases using both Synoicus chinensis and older names including Coturnix chinensis and Excalfactoria chinensis.
• Check local records for wet grassland, swamp margins, shrubland, paddyfield-like areas and farmland with dense ground cover.

Distribution: Conservation status

The species is not listed under the Australian Environment Protection and Biodiversity Conservation Act 1999. It is listed as Endangered in Victoria under the Victorian threatened fauna framework.

EPBC Act: Not listed

Victoria: Endangered

• Apply the relevant Victorian threatened species requirements where the project is in Victoria, even though the species is not EPBC listed.

Habitat: Habitat types

Blue-breasted Quail habitat is low, dense and often damp vegetation where birds can feed, move under cover and nest on the ground. The sources identify habitat types but do not provide elevation limits, vegetation community names or measured cover requirements.

Reported habitats include wet and swampy grasslands, shrublands and paddyfields. eBird also describes lowland plains, grassy hillsides and farmland.

Suitable project habitat may occur in wet depressions, swamp margins, dense grass patches, weedy or fallow paddocks, low shrub cover and farmland with continuous ground vegetation.

Elevation and climate limits: Not specified in the supplied sources

Key habitat types: Wet or swampy grassland, shrubland, paddyfields, lowland plains, grassy hillsides and farmland

Habitat: Habitat structure

The species needs enough low vegetation to provide concealment at ground level. Dense grass and other ground cover also provide nest material and shelter from disturbance.

The supplied sources do not give measured vegetation height, patch size, canopy cover or distance to water. Retain connected patches of dense ground cover where practicable and avoid assuming that apparently ordinary grassland is unsuitable.

• Inspect damp grassland, swampy areas, shrub edges and dense farmland vegetation before clearing.
• Map retained ground-cover patches and their connections to nearby wet grassland or shrubland.
• Avoid unnecessary removal of long grass, low shrubs and loose herbage during site preparation.

Foraging habitat: Food

The Blue-breasted Quail feeds on the ground in grassy and other low-cover habitats. Its diet includes plant material and small invertebrates, so clearing can remove both feeding cover and food resources.

The reported diet consists of grass seeds, rape seeds, green vegetation and small insects, particularly termites and their larvae.

The supplied sources do not identify particular native food plants or quantify daily food intake.

Plant food: Grass seeds, rape seeds and green vegetation

Animal food: Small insects, particularly termites and termite larvae

Foraging habitat: Foraging method and area

The species is a ground-feeding quail associated with lowland plains, grassland, grassy hillsides and farmland. It may remain concealed in vegetation and flush only when approached closely.

No foraging home-range size, travel distance or population density is provided. During site inspections, assess the full area of connected ground cover rather than only the immediate location of an observation.

• Look for birds in dense grass, wet ground cover, shrub margins and low vegetation adjoining farmland.
• Retain undisturbed ground cover around known or suspected feeding areas where the project design allows.
• Control sediment, weeds and runoff so that retained wet grassland and ground vegetation are not degraded during works.

Breeding habitat: Breeding biology

Blue-breasted Quail nests on the ground in a grass-lined hollow or scrape. Breeding habitat therefore depends on undisturbed ground cover, suitable nest concealment and access to nearby feeding areas.

Breeding season: Wild breeding season is not specified. Captive birds are reported to breed year-round.

Clutch size: Usually 4 to 7 eggs in one source, with 6 to 14 reported in another source

Eggs: Olive green to brown, with dark brown spots or blotches

Incubation: 16 to 19 days, with 16 to 18 days also reported

Age at maturity: About 3 months

Lifespan: About 1.5 years reported in the wild; typically 3 to 6 years in captivity, with up to 13 years recorded in captivity

Chick development: Chicks can fly after about one month

Breeding habitat: Nest habitat

The nest is a simple scrape or ground hollow lined with dry grass. Captive observations also describe nest sites in a quiet corner or depression, often near long grass, tea-tree branches or loose herbage.

Natural breeding behaviour is not fully documented in the supplied sources. On a project site, any concealed ground hollow within dense grass or low cover should be treated as a possible nest until inspected.

• Complete a pre-clearance inspection of dense grass, swamp margins, shrubland and other ground-cover patches.
• Use staged clearing and fauna spotter catcher supervision where a suspected nest or recently flushed adult is found.
• Avoid disturbing suspected nests until the species specialist or relevant authority has advised on the response.

Sheltering habitat: Ground cover

This is a ground-dwelling species that shelters in dense low vegetation rather than trees or elevated roosts. The supplied sources do not report burrows, hollows, dens, roost structures or measured shelter dimensions.

Wet grassland, shrubland, paddyfield margins, grassy hillsides and farmland can provide concealment for birds that spend most of their time on the ground.

The short dark tail, ground-based habits and tendency to flush from almost underfoot indicate that dense low cover is important for daytime shelter and escape.

Shelter type: Dense ground vegetation, grassland and low shrub cover

Known shelter dimensions: Not provided in the supplied sources

• Retain continuous grass and low shrub cover around wet areas and known records where practicable.
• Inspect vegetation from the edge before entering or slashing dense cover.
• Avoid parking, stockpiling materials or storing spoil on retained ground-cover patches.

Sheltering habitat: No reported tree or subterranean refuge

The supplied sources do not identify use of tree hollows, burrows, caves, elevated roosts or dens. Protection should focus on ground cover, grass-lined hollows and connected low vegetation.

Threats: Clearing and construction

The supplied sources do not provide a formal threat assessment or quantify population decline. For Australian projects, the main management concern is the direct loss or disturbance of wet grassland, shrubland and dense ground cover used for feeding, shelter and ground nesting.

Clearing can remove feeding habitat, concealment and ground nests at the same time. Earthworks, slashing, grading, trenching, vehicle movement and material storage can also disturb birds in retained habitat.

The species is small, ground dwelling and easily overlooked, so a lack of observations during a brief inspection does not demonstrate that a patch is unused.

• Survey and mark wet grassland, dense grass, shrubland and other suitable ground cover before clearing.
• Use a fauna spotter catcher during staged clearing where required by the approval or site environmental management plan.
• Keep machinery, access tracks, spoil and laydown areas out of retained habitat.
• Stop work and obtain ecological advice if a nest, dependent young or repeatedly flushed quail is found.

Threats: Fragmentation, roads and predators

The supplied sources do not quantify the effects of fragmentation, roads, introduced predators or domestic animals on this species. These risks should nevertheless be assessed because the bird nests and feeds at ground level in low vegetation.

Road construction and increased traffic can remove habitat, divide ground-cover patches and increase the risk of birds being flushed into vehicle paths.

• Maintain links between retained grassland, wet areas and shrub cover where practicable.
• Set low vehicle speeds near retained habitat and prohibit unnecessary driving through dense ground cover.
• Prevent dogs and other domestic animals from entering retained habitat and manage waste that may attract predators.
• Record all fauna interactions, including flushes and vehicle strikes, during construction.

Threats: Fire and hydrology

The sources do not describe a fire regime, disease threat or specific hydrological tolerance. Because the species is associated with wet or swampy grassland and paddyfield habitat, changes to drainage, inundation, runoff or sediment movement should be assessed.

Fire, mowing or slashing that removes dense ground cover can reduce shelter and expose nests and birds. The timing and intensity of any vegetation treatment should be managed around confirmed records and suspected breeding habitat.

• Prevent uncontrolled changes to drainage and avoid diverting clean or sediment-laden water into retained habitat.
• Inspect wet depressions and swamp margins after major hydrology changes or vegetation disturbance.
• Use the least intensive practicable fire, mowing and slashing treatment in habitat supporting records or repeated flushes.
• Report unusual mortality or sick birds through the relevant wildlife or biosecurity pathway.

Survey methodology: 1. Diurnal habitat searches

Blue-breasted Quail is a small, ground-dwelling bird of wet or swampy grasslands, shrublands and paddyfields. It can remain hidden in dense low cover and may flush from almost underfoot, so surveys should combine careful daytime searches with targeted listening and observation.

Walk systematic transects through suitable low vegetation, wet grassland, swamp margins, shrubland and other ground-cover habitats before disturbance.

Use a slow search pace and record birds that flush, call, run through cover or are seen feeding on the ground.

Give particular attention to dense grass, vegetation near wet areas and sheltered ground where a bird could remain concealed.

Adult length: 12 to 15 cm

Typical habitat: Wet or swampy grasslands, shrublands and paddyfields

• Define the survey area, transect spacing, walking speed and search period before starting, and record the area covered and time spent searching.
• Repeat searches where dense vegetation, poor visibility or high background noise is likely to reduce detection.
• Record sex, plumage, behaviour, location, habitat, direction of travel and the condition of the site.

Survey methodology: 2. Dawn and dusk observation and listening

Conduct observations during periods when birds are likely to move or call, with timing selected for local conditions and project constraints.

Listen for the male's descending plaintive whistle, described as a tew-tew or ti-yu call, and for raspy or snoring calls and sharp calls when birds flush.

Use quiet observation points near suitable cover and wet areas, and avoid excessive movement that could cause birds to remain hidden.

Male call: Descending, plaintive whistle, also described as tew-tew or ti-yu

Other calls: Raspy or snoring call, sharp cheeps and tir-tir-tir calls when flushed

• Record start and finish times, weather, wind, rain, visibility, noise and the length of each listening period.
• Do not treat the absence of calls as evidence that the species is absent, because the species is generally uncommon and may only be seen briefly when flushed.
• Map all detections and likely movement routes between retained patches of ground cover.

Survey methodology: 3. Breeding and nest searches

Inspect suitable ground cover for nests before clearing, particularly grass-lined hollows in dense grass and sheltered vegetation.

Treat any scrape, hollow or ground nest containing eggs, chicks or nesting material as an active fauna feature until assessed by an authorised person.

Plan searches to avoid trampling potential nests and use a spotter catcher familiar with low, ground-nesting birds.

Nest location: On the ground in a grass-lined hollow

Reported clutch size: 4 to 14 eggs in the supplied sources

Incubation: 16 to 19 days in, and 16 to 18 days in

• Record the nest location, surrounding cover, water conditions, evidence of use and any eggs or chicks without unnecessarily approaching or handling them.
• If a nest is found, establish a site-specific exclusion area and obtain advice from the relevant wildlife authority or project fauna management plan before works continue.

Survey methodology: Minimum effort and reporting

• Use a survey effort that is proportionate to the area and quality of suitable habitat, because the supplied documents do not provide a species-specific Australian survey guideline or prescribed number of nights, hours, transects, area or trap nights.
• Do not use trapping as a routine detection method unless it is justified by the project method, approved by the relevant authority and undertaken by appropriately authorised personnel.
• Record all survey effort, including dates, times, observers, transect lengths or areas, listening periods, weather, limitations and results.
• Submit confirmed records and suitable negative-survey information to the relevant state wildlife database and retain the data with the project environmental records.
• Check current state survey guidance and local permit conditions before finalising the method.

Before habitat disturbance: Avoid and minimise

Plan the works around the species' dependence on dense ground cover and its ground-nesting habit. The Australian population is not listed under the EPBC Act in the supplied material, but the species is listed as endangered in Victoria.

Retain wet or swampy grassland, dense shrub cover, paddyfield-like habitat and connected strips of low vegetation wherever practicable.

Avoid breaking connections between retained patches, particularly where cover provides movement routes between feeding and nesting areas.

Keep machinery, vehicle access, spoil, drainage works and laydown areas out of retained wet ground and dense ground cover.

• Prioritise retention of intact ground vegetation and sheltered grass-lined hollows before considering relocation or reinstatement.
• Design the clearing footprint to leave continuous retained habitat rather than isolated small patches.
• Prevent changes to drainage that would dry suitable wet or swampy habitat or send sediment into retained areas.

Before habitat disturbance: Approvals and planning

Confirm the current EPBC Act assessment outcome and state or territory requirements before works begin.

In Victoria, check the requirements applying to the threatened species listing and obtain any required permits or approvals.

Prepare a fauna management plan that identifies suitable habitat, survey results, exclusion areas, stop-work triggers, handling arrangements and reporting responsibilities.

Australian EPBC Act status in supplied material: Not listed

Victoria status in supplied material: Endangered

• Confirm whether the project requires an EPBC referral even though the supplied material states that the species is not nationally listed.
• Confirm state wildlife permits for fauna survey, capture, handling, release or nest management before appointing a fauna spotter catcher.
• Set out who can authorise a stop, who can handle birds and where injured birds will be taken.

Before habitat disturbance: Site preparation

Complete a pre-clearance survey immediately before works in suitable habitat, using the approved project method and checking for birds, calls, nests and movement through cover.

Mark retained habitat, wet areas, nest exclusions, access routes and no-go areas clearly on plans and on the ground.

Install exclusion fencing where it can prevent machinery and personnel entering retained habitat, while maintaining any required fauna movement routes.

• Brief operators on the species' small size, ground-dwelling behaviour and tendency to flush from close to a person's feet.
• Inspect fencing daily for gaps, trapped animals and impacts on movement before clearing starts.
• Stage clearing so that the spotter catcher can search each section before machinery enters it.

During habitat disturbance: Daily clearing controls

A fauna spotter catcher should control the interface between clearing crews and ground habitat. The species is small, difficult to detect in cover and nests on the ground, so machinery must not advance ahead of the fauna inspection.

Inspect the active work area at the start of each day and after breaks, weather changes or movement of the clearing boundary.

Clear in small, manageable stages so the spotter catcher can maintain line of sight and check ground cover before machinery moves in.

Keep retained wet areas, grassland, shrubland and marked exclusion areas outside the active work zone.

• Use a pre-start briefing to confirm the day's clearing limits, fauna risks, access routes, communication signals and emergency contacts.
• Stop machinery immediately when the spotter catcher gives the agreed stop signal or loses visual contact with the work face.
• Do not permit night clearing in suitable habitat unless it is specifically assessed, approved and supervised under the fauna management plan.

During habitat disturbance: Fauna spotter catcher and machinery

Position the spotter catcher where the ground ahead of the machine, the cutting head and the escape direction can be seen safely.

Have the operator pause while the spotter catcher checks dense grass, shrub bases, wet margins, ground hollows and debris before disturbance.

Keep the machine stationary while the spotter catcher assesses any flushed or concealed bird and confirms that the work area is clear.

• Maintain a safe separation from machinery and never require the spotter catcher to enter an unsafe exclusion zone.
• Use hand signals or radio calls that are understood by the operator and tested before clearing begins.
• Do not chase a flushed bird into retained habitat or continue clearing while its location is uncertain.

During habitat disturbance: Animals, nests and habitat features

If a Blue-breasted Quail is found, stop work locally and allow the bird to move into retained nearby cover where it can do so safely.

Only an appropriately authorised person may capture, handle or relocate the bird, and handling should be limited to what is necessary for safety, assessment or approved relocation.

If an active nest, eggs or chicks are found, stop work around the nest and follow the approved authority and fauna management plan requirements.

• Release a healthy bird into nearby retained habitat that provides suitable dense ground cover, unless the relevant authority directs another action.
• Place an injured bird in a suitable dark, quiet container and transfer it promptly to a veterinarian or authorised wildlife carer through the nominated project procedure.
• Treat logs, rocks, dense grass clumps, ground hollows and wetland edges as potential cover or nesting features and inspect them before removal.
• Do not move or destroy habitat features containing an animal until the spotter catcher has assessed them and the required authorisation is in place.

During habitat disturbance: Stop-work triggers and records

Stop work in the immediate area for any live bird, active nest, injured animal, suspected trapped animal or unconfirmed detection within the clearing footprint.

Record each detection, attempted escape route, handling event, relocation, injury, nest, stop and restart decision.

Report incidents to the project environmental officer and the relevant authority when required by the permit or fauna management plan.

• Record the date, time, precise location, habitat, activity, personnel, machinery status, action taken, release location and outcome.
• Photograph habitat and locations where this can be done without disturbing the bird or nest.
• Update the daily clearing map to show cleared areas, retained habitat, exclusions and fauna incidents.

After habitat disturbance: Post-clearance checks

Post-clearance work should check that no birds, nests or injuries were missed and that retained habitat controls remain effective. Records should support compliance and future management of the species in Victoria and elsewhere in Australia.

Inspect the cleared edge, retained vegetation, wet areas, access routes and spoil margins after each clearing stage.

Search for birds that may have remained in cover, injured animals, disturbed nests and animals trapped by fencing, trenches or other works.

Keep fauna exclusions in place until the environmental officer confirms that the risk from the relevant activity has ended.

• Check trenches, pits, pipes and other excavations at the frequency required by the fauna management plan and before they are backfilled.
• Remove or modify controls that could trap or prevent movement of ground-dwelling birds once they are no longer needed.
• Document the completion of each post-clearance inspection and any corrective action.

After habitat disturbance: Monitoring and reporting

Monitor retained habitat and rehabilitation areas for Blue-breasted Quail detections, calls, nest evidence and changes in ground cover.

Compare post-work observations with the pre-clearance survey, noting changes in wetness, grass cover, shrub cover, connectivity and disturbance.

Report confirmed records and fauna incidents through the project reporting system and to the relevant state wildlife database.

• Continue monitoring for the period required by approval conditions or the fauna management plan.
• Review monitoring results with the project ecologist and adjust access, drainage, weed control or clearing controls where suitable habitat is being degraded.
• Retain survey data, photographs, maps, permits, incident forms and database submission confirmations.

After habitat disturbance: Offsets and compliance close-out

Assess any unavoidable loss of suitable habitat against the applicable approval, state policy and project offset requirements.

Do not describe an offset as a substitute for avoiding or minimising clearing of occupied or suitable habitat.

Close out the work only after required fauna actions, rehabilitation commitments, monitoring and regulatory reporting are complete.

• Record the area and type of suitable habitat cleared and retained using the project's approved mapping method.
• Confirm whether the Victorian threatened species listing creates additional management or reporting obligations for the project.
• Escalate any unexpected mortality, repeated detections in the work area or failure of rehabilitation controls to the approval holder and regulator where required.

Rehabilitation actions: Restore habitat structure

Rehabilitation should restore the low, dense and often wet ground cover used by this quail for feeding, shelter and nesting. The supplied documents do not identify Australian planting lists, nest-box requirements or fire regimes for this species, so those measures must be set by the local ecologist and approval conditions.

Reinstate wet or swampy grassland, shrubland and other dense low vegetation where these communities occurred before the works.

Use locally appropriate native grasses, sedges, herbs and shrubs selected for the site's soil, hydrology and pre-clearing community rather than a generic seed mix.

Recreate sheltered ground cover and grass-lined hollows suitable for a ground nest.

• Restore natural drainage patterns where construction has altered wet ground, while preventing erosion and sediment entry into retained habitat.
• Avoid leaving broad areas of bare ground, regularly mown grass or dense weeds within rehabilitation areas.
• Do not place stockpiles, mulch or woody debris so densely that they remove the low ground cover needed for movement.

Rehabilitation actions: Replace cover and manage threats

Retain or reinstate suitable logs, rocks and other ground cover only where they occur in the local habitat and do not obstruct quail movement or create construction hazards.

Use nest boxes only if a site ecologist and the relevant authority identify them as suitable, because the supplied documents describe this species as a ground nester rather than a hollow nester.

Control weeds that replace native grass and shrub cover, and manage introduced predators in accordance with the site management plan and legal requirements.

• Keep domestic animals and unauthorised access out of rehabilitation areas while vegetation establishes.
• Do not burn or mechanically clear rehabilitation areas without a site-specific fire and fauna assessment.
• Plan fire management to retain dense ground cover and protect active nests during the breeding period identified by local monitoring.

Rehabilitation actions: Measure success

Monitor plant establishment, ground-cover density, wetland condition, weed cover, predator activity and connectivity with retained habitat.

Use repeat searches and listening surveys to check for Blue-breasted Quail presence, calls, flushing records and evidence of ground nesting.

Set success measures in the rehabilitation plan using the pre-clearing habitat condition and the applicable approval conditions as the reference.

Relevant habitat feature: Dense wet or swampy grassland, shrubland or paddyfield-like ground cover

Relevant nest feature: Ground nest in a grass-lined hollow

• Record the area rehabilitated, methods used, planting or seeding details, rainfall or site conditions, maintenance and monitoring results.
• Replace failed plants or repair erosion, drainage, fencing and weed-control measures when inspections identify a problem.
• Continue monitoring until the agreed habitat condition and fauna outcomes have been met, and report failures and corrective actions to the approval holder and regulator where required.
