Inland Dotterel (Peltohyas australis)

Conservation status

Victoria, Flora and Fauna Guarantee Act 1988: Vulnerable.

Breeding season

The annual pattern is variable because movement and breeding respond to rainfall. The months below provide a broad seasonal planning guide based on the reported spring and summer movements, not a fixed breeding calendar.

Months are January to December. No month-specific breeding or presence data are provided in the supplied documents, and rainfall can shift the pattern between years and districts.

• Breeding: Breeding may occur after heavy rainfall, so activity can occur outside a fixed seasonal window. Spring to early summer is shown as a broad planning period only.
• Young: Dependent young may be present when rainfall has triggered local breeding. The supplied documents do not provide a period for dependence.
• Seasonal movement: Birds appear to move south in spring and north in summer, and also move in response to rainfall and drought. Exact timing varies between districts.
• Night foraging: Night activity and road foraging can occur throughout the year when birds are present. Birds may be more difficult to detect during the day.
• Highest clearing risk: Risk is highest when birds are present and breeding has followed rainfall. Because the species can breed at variable times, all suitable open ground should be checked before clearing rather than relying on a fixed seasonal closure.

Identification

Inland Dotterels are cryptically coloured, medium-sized plovers of dry inland plains. They are usually detected by their distinctive adult markings, nocturnal activity or shallow ground nests rather than by conspicuous daytime movement.

Adults have sandy-coloured plumage that blends with dirt, gibber and gravel. Distinctive dark markings include a black band across the crown and through the eye, a black collar and a Y-shaped pattern on the breast.

Identification: Size and sex

The supplied documents describe the species as medium-sized but do not provide adult length, mass or measurements for males and females. They do not describe reliable differences between the sexes.

Adult size: Medium-sized plover; numerical measurements are not provided in the supplied documents

Sex differences: Not described in the supplied documents

Identification: Field signs

Look for birds moving or feeding on outback roads at night, usually alone or in pairs. During the day they may be difficult to see among bare ground and scattered rocks, and may occur in small flocks or, outside the breeding season, in flocks of hundreds.

Nests are shallow scrapes on the ground. Eggs may be laid directly on bare ground or on a scrape lined with small stones, dry grass or animal dung. When disturbed, adults may cover the nest with debris or nesting material, or feign injury to draw attention away from eggs or young.

• Search bare and sparsely vegetated ground carefully before clearing or vehicle access, because cryptic adults and nests may be overlooked.
• Treat a bird repeatedly using a particular patch of bare ground, or an adult performing a distraction display, as a prompt for a targeted nest search and exclusion area.

Distribution: National range

The Inland Dotterel is endemic to Australia and is associated with arid inland regions rather than the coast. The supplied documents do not provide a state-by-state range, mapped bioregions, stronghold locations, subpopulation boundaries or population estimates.

The species occurs in arid south-eastern and south-western Australia. It favours remote inland areas and is rarely found near shorelines, although exceptionally it may reach the coast.

Endemism: Australian endemic

Broad range: Arid south-eastern and south-western Australia

Coastal records: Very rare; birds may occasionally reach the coast

Distribution: Movements and population information

Movements are poorly known. Birds appear to move south in spring and north in summer, and also move in response to rainfall and drought. They may leave an area when conditions become excessively wet or dry.

The supplied documents do not give a national population size, population trend, named strongholds, recognised subpopulations or bioregion-level distribution.

Population size: Not provided in the supplied documents

Population trend: Not provided in the supplied documents

Strongholds and subpopulations: Not identified in the supplied documents

• Do not assume that an apparently empty site is unused, particularly after rainfall or during periods when suitable sparsely vegetated habitat is available.
• Review recent records and local rainfall before works because occupancy can change between seasons and in response to drought or heavy rain.

Habitat: Habitat types

Inland Dotterels use flat, open and sparsely vegetated arid country. Their habitat is defined more by bare ground and short vegetation than by proximity to water.

Typical habitat includes gibber plains, clay plains and gravel flats, with scattered short vegetation. The species can occur far from water and in some of the hottest and most exposed parts of Australia.

• Prioritise assessment of flat open areas with extensive bare soil, gibber, clay or gravel and low, sparse vegetation.
• Include apparently poor or heavily exposed ground in habitat assessments, rather than restricting searches to drainage lines or wetlands.

Habitat: Climate and structure

The species is adapted to extreme heat, little shade and exposed conditions. It has salt glands above the eyes that help remove excess salts from the body and from succulent plants it eats.

No elevation limits, vegetation community names, canopy thresholds or minimum patch sizes are provided in the supplied documents.

Elevation limit: Not provided

Climate association: Arid, hot and exposed inland conditions

Vegetation structure: Sparse, short vegetation with substantial open ground

• Map areas of flat open ground, sparse vegetation and scattered stones within the proposed disturbance footprint.
• Retain connected areas of suitable open ground where practicable, because the species responds to rainfall and drought and may shift between areas.

Foraging habitat: Diet

Inland Dotterels switch between plant foods and animal prey across the day. They are most active at night and may be encountered feeding on roads through suitable arid habitat.

During the day, birds pluck succulent leaves and seeds from low vegetation. At night they feed on insects, ants and spiders.

Day diet: Succulent leaves and seeds

Night diet: Insects, ants and spiders

Foraging habitat: Foraging areas and behaviour

Birds are more active at night and are commonly seen foraging on outback roads. They usually feed alone or in pairs at night, while daytime groups may be small or, outside the breeding season, may number in the hundreds.

Foraging range: No numerical foraging range is provided

Typical night grouping: Usually alone or in pairs

Non-breeding daytime grouping: Small flocks, sometimes numbering in the hundreds

• Avoid night vehicle movements through suitable open habitat where practicable, and use a slow speed and active observation when access is necessary.
• Inspect road verges, borrow areas, laydown areas and other bare open surfaces because these can provide feeding habitat even when they contain little vegetation.
• Do not infer that a site is unimportant from a lack of daytime sightings.

Breeding habitat: Breeding habitat

Breeding is associated with open bare ground and appears to be rainfall dependent. The nest is a minimal ground scrape that can be difficult to detect during pre-clearance inspections.

Inland Dotterels nest on open ground in their arid habitat. Suitable nest sites may be bare, or may contain small stones, dry grass and animal dung used as nest lining.

• Search flat open ground, gibber, clay and gravel surfaces after heavy rainfall and before clearing.
• Inspect proposed access tracks, pads, stockpile areas and other open disturbed surfaces because the nest is a shallow scrape on the ground.

Breeding habitat: Breeding biology

The supplied documents do not provide a fixed breeding season, clutch size, incubation period, age at maturity or lifespan. They state that birds may appear and breed in some districts after heavy rainfall, and may leave when conditions become excessively wet or dry.

If an adult covers a patch with debris, gives a distraction display or repeatedly returns to a small area, stop work locally and arrange a targeted inspection by an appropriately experienced fauna spotter catcher.

Breeding season: Variable and rainfall dependent; breeding may follow heavy rainfall

Clutch size: Not provided in the supplied documents

Incubation: Not provided in the supplied documents

Age at maturity: Not provided in the supplied documents

Lifespan: Not provided in the supplied documents

Nest type: Shallow ground scrape, sometimes lined with small stones, dry grass or animal dung

Sheltering habitat: Daytime cover

The supplied documents do not describe roost sites, burrows, hollows or refuges used by Inland Dotterels. Their main known sheltering strategy is camouflage in open ground and concealment of the nest when disturbed.

Sandy-coloured plumage provides camouflage among dirt and gibber rocks. During the day, birds may remain difficult to detect in sparsely vegetated plains and may occur in flocks.

• Use systematic searches of open ground rather than relying only on flushed birds or obvious cover.
• Limit unnecessary pedestrian and vehicle movement through suitable habitat during daylight and at night.

Sheltering habitat: Nest concealment

The nest is exposed on the ground rather than in a burrow, hollow or dense vegetation. If disturbed, adults may cover the nest with debris or nesting material.

Burrows or hollows: Not described

Known refuge structure: Camouflaged open ground and concealed ground nests

Roost dimensions: Not provided

• Do not remove stones, dry grass, dung or other loose material from suspected nest areas until the area has been checked.
• Treat fresh debris covering an otherwise bare patch as a possible concealed nest, particularly where an adult is nearby or gives a distraction display.

Threats: Clearing and construction

The supplied documents identify the species' dependence on sparse open arid habitat, cryptic ground nests and rainfall-driven movements. They do not provide a species-specific threat assessment, so project controls should focus on direct habitat loss, nest destruction and disturbance in suitable open ground.

Clearing, grading, earthworks, stockpiling and temporary access can remove or disturb the open gibber, clay and gravel surfaces used for feeding and nesting. Ground nests may be missed because they are shallow and cryptic.

• Complete targeted pre-clearance searches of suitable open ground before clearing, especially after heavy rainfall.
• Mark and protect any active nest or distraction-display location from plant, vehicles and personnel until the breeding event has ended and a suitably qualified ecologist has confirmed that work can proceed.
• Keep temporary compounds, laydown areas, spoil and access tracks out of sparsely vegetated open habitat where practicable.

Threats: Roads and night disturbance

Inland Dotterels commonly forage on outback roads at night. Night traffic and construction lighting can therefore overlap with feeding activity, while vehicle movements may cause direct collision or disturbance.

• Manage night vehicle speeds and movements through suitable habitat, particularly where birds are observed feeding on roads.
• Avoid unnecessary lighting directed onto open foraging areas.
• Record night observations and road-use locations during fauna monitoring.

Threats: Fire, predators and other pressures

The supplied documents do not specify the effects of fire, fragmentation, introduced predators, disease or hydrology change on Inland Dotterels. They do show that the species responds to drought, heavy rainfall and conditions that become excessively wet or dry.

• Assess whether a project changes surface water, drainage or access in a way that could make suitable ground excessively wet or dry.
• Consider increased access and disturbance as potential risks where roads or infrastructure open previously remote habitat.
• Do not assign species-specific fire, predator or disease impacts without local evidence or a project-specific assessment.

Survey methodology: 1. Habitat assessment and daytime searches

Survey effort should reflect the Inland Dotterel’s use of open, arid country and its stronger activity at night. The supplied documents do not provide a species-specific survey guideline or minimum effort, so the project ecologist should set effort from the disturbance area, habitat quality, season and survey objectives.

Inspect all proposed disturbance areas during daylight for flat, open, sparsely vegetated habitat, including gibber plains, clay plains and gravel flats.

Walk or drive systematic transects across representative habitat and record the area searched, transect length, start and finish times, weather, visibility, vegetation cover, surface type and any Inland Dotterel observations.

Search slowly and use binoculars where possible because the species has cryptic, sandy-coloured plumage and can be difficult to detect among dirt and gibber rocks.

Record flock size, locations, behaviour, tracks or other signs, and any shallow scrapes, eggs or adults showing distraction behaviour.

Survey methodology: 2. Nocturnal searches

Undertake targeted night searches because Inland Dotterels are more active after dark and commonly forage on outback roads at night.

Use a consistent spotlighting route or walked transect covering all accessible suitable habitat, and record the route, area searched, search time, weather, moon conditions, visibility and detection distance.

Search for birds on open ground and roads, while avoiding driving speeds and lighting practices that could create a collision risk or disturb birds.

Where safe and permitted, repeat night searches on separate nights rather than relying on one visit, particularly where habitat is extensive or rainfall has recently made the site suitable.

Survey methodology: 3. Seasonal and rainfall targeting

Schedule surveys across the period when the site is most likely to support the species, using local records, seasonal movements and recent rainfall to guide timing.

Give additional attention to areas where birds appear after heavy rainfall, and reassess sites if conditions become excessively wet or dry because birds may leave when habitat becomes unsuitable.

Consider surveys during both daylight and night because birds may feed on plant material during the day and insects, ants and spiders at night.

Repeat the assessment if a project is staged across seasons or if clearing is delayed into a materially different rainfall period.

Survey methodology: 4. Minimum effort and reporting

• Prepare a written survey design before fieldwork that states the search area, transect layout, number and duration of visits, night and daylight effort, weather and rainfall conditions, detection limits and any access constraints.
• Do not describe a site as free of Inland Dotterels solely because no birds were detected during one visit, particularly where suitable open habitat remains or recent rainfall has occurred.
• Map all records and potential nesting areas in project plans and provide the data to the project ecologist and relevant approval authorities.
• Submit confirmed records, including negative survey information where required by the approval, to the relevant state wildlife database.
• Retain survey dates, tracks, photographs, observer names, equipment settings and habitat descriptions with the project environmental records.

Before habitat disturbance: Avoid and minimise

Avoid clearing suitable open habitat wherever practicable. Inland Dotterels use sparsely vegetated arid plains, can nest directly on bare ground, and may move into an area following rainfall.

• Retain flat, open gibber, clay and gravel areas that are outside the construction footprint, especially where birds have been recorded or where nesting scrapes are present.
• Keep retained habitat connected to nearby areas of similar open country and avoid creating unnecessary roads, laydown areas or stockpiles across movement routes.
• Avoid unnecessary changes to surface drainage, soil crusts and low vegetation that provide the species’ foraging and nesting substrate.
• Use the smallest practicable disturbance footprint and locate access tracks, camps and compounds in already disturbed areas where feasible.

Before habitat disturbance: Approvals and work planning

• Check the current national and state threatened species registers before works begin and obtain all required permits, approvals and authorisations.
• Assess whether the action requires an EPBC Act referral and address the relevant state approval requirements for the project location.
• Plan clearing outside periods when birds are present or breeding where local survey information supports a lower-risk timing window.
• Use recent rainfall and local records when setting the work program because birds may arrive and breed in some districts after heavy rainfall.
• Prepare a fauna management plan that defines survey triggers, exclusion areas, stop-work procedures, authorised handlers, release locations, veterinary contacts and reporting requirements.

Before habitat disturbance: Pre-clearance preparation

• Complete a pre-clearance search of all areas to be disturbed, including access routes, temporary work areas and spoil or material storage areas.
• Mark approved clearing limits and any active nest, bird concentration or retained habitat exclusion area clearly on the ground and in construction plans.
• Use exclusion fencing where it can keep machinery and people out of a confirmed nest or retained habitat without blocking necessary movement between suitable areas.
• Brief all supervisors, machine operators and fauna spotter catchers on the species’ cryptic appearance, nocturnal activity, nesting behaviour and stop-work requirements.

During habitat disturbance: Daily controls and spotter catcher duties

Inland Dotterels are exposed on open ground and their nests may be shallow scrapes with little or no lining. Clearing controls must therefore cover the ground surface, not only trees and large habitat features.

• Complete a daily pre-start inspection of the approved work area, access tracks and exclusion zones before machinery enters the site.
• Have the fauna spotter catcher inspect the active work area immediately before clearing and remain positioned where the machine operator can see the spotter’s stop signal.
• Clear progressively in small sections so the spotter can inspect ground ahead of machinery and check areas as they are opened.
• Use lighting and vehicle controls that reduce disturbance and collision risk during night work, and avoid unnecessary night driving through suitable habitat.
• Suspend work in an area if visibility, dust, rain or vehicle movement prevents the spotter catcher from safely inspecting the ground.

During habitat disturbance: Ground nests and habitat handling

• Treat any shallow scrape, eggs, dependent young, alarm-calling adult or adult performing a distraction display as a potential active nest or breeding site.
• Do not touch, cover, move or drive over a suspected nest unless the action is authorised under the project fauna management plan and by the relevant authority.
• Do not assume a nest is empty because it contains little lining, because eggs may be laid directly on bare ground.
• Retain nearby low vegetation, surface stones and undisturbed ground around an active or suspected nest until the ecologist confirms the required exclusion and next steps.
• Inspect and manage rocks, logs, debris and soil piles as potential shelter or obstruction hazards even though the supplied documents do not identify a specific dependence on these features.

During habitat disturbance: If an animal is found

• Stop machinery immediately when an Inland Dotterel is found inside the work area, and keep workers, vehicles and dogs away from the bird.
• Allow the bird to move away naturally where it is mobile and uninjured, while the spotter catcher maintains a safe separation and prevents it being driven towards active works.
• Only an appropriately authorised and trained person may capture or handle the bird, and handling should be limited to what is necessary for safety, assessment or approved relocation.
• Relocate a healthy bird only where the fauna management plan and relevant approvals allow it, using nearby retained habitat with similar open, sparsely vegetated conditions.
• Place an injured or exhausted bird in a secure, quiet container and transfer it promptly to a veterinarian or authorised wildlife carer.
• Treat repeated alarm calls, distraction displays, a nest or young, or a bird unable to leave the work area as triggers for stop-work and ecologist review.

During habitat disturbance: Records and stop-work reporting

• Record every sighting, capture, injury, nest, exclusion zone and release, including location, date, time, observer, behaviour, action taken and outcome.
• Photograph and map any suspected nest or breeding area without approaching unnecessarily.
• Notify the site supervisor and project ecologist before work resumes in an area where a bird, nest or dependent young has been found.
• Escalate repeated sightings, breeding behaviour, injury or mortality to the relevant approval authority where required by the permit or fauna management plan.

After habitat disturbance: Post-clearance checks

Post-clearance work should confirm that no birds, nests or injured fauna remain in the disturbed area and that retained habitat controls have stayed in place.

• Inspect the cleared area, work edges, access tracks and exclusion zones after each clearing stage for birds, nests, eggs, injured fauna and disturbance outside the approved footprint.
• Complete additional night checks where works affected roads or open arid habitat used for nocturnal foraging.
• Confirm that no spoil, equipment, fencing or traffic controls obstruct retained open habitat or access between retained areas.
• Remove temporary barriers only after the project ecologist confirms that the area is safe and the work stage is complete.

After habitat disturbance: Monitoring and maintenance

• Monitor retained habitat for Inland Dotterel use, flocking, breeding behaviour and changes following rainfall during the construction period.
• Maintain exclusion fencing, signage, access controls and low-speed vehicle controls for as long as the risk remains.
• Inspect rehabilitation and retained habitat after rainfall and after major construction events because birds may move into suitable areas in response to changed conditions.
• Use the same mapped locations and observation methods where practical so records can be compared between monitoring visits.

After habitat disturbance: Reporting and corrective action

• Report survey results, sightings, incidents, injuries, mortalities, nest protection measures, releases and rehabilitation results in the project environmental report.
• Provide required records to the relevant state wildlife database and approval authorities.
• Investigate any mortality, repeated disturbance or use of habitat outside the approved footprint, and revise controls before continuing the affected activity.
• Apply any approved offset or compensatory measure where residual impacts remain after avoidance and mitigation.

Rehabilitation actions: Restore the ground surface

Rehabilitation should recreate open, sparsely vegetated arid habitat rather than dense vegetation. The supplied documents do not identify particular plant species, nest box requirements or habitat restoration targets for Inland Dotterels.

• Reinstate flat, stable ground and the local gibber, clay or gravel surface where those materials formed the pre-disturbance habitat.
• Remove construction rubble, surplus soil, temporary matting and other obstacles from areas intended to function as open foraging or nesting habitat.
• Avoid establishing dense planted cover across areas that were previously open and sparsely vegetated.
• Prevent altered drainage, erosion and sediment deposition from making retained or rehabilitated flats excessively wet or unstable.

Rehabilitation actions: Vegetation, weeds and predators

• Use locally appropriate native species and densities based on the pre-clearing vegetation community and the ecological restoration advice for the project region.
• Control weeds so rehabilitation remains sparsely vegetated and structurally similar to suitable nearby Inland Dotterel habitat.
• Manage feral predators and other introduced animals in accordance with the approved site management plan where they threaten ground-nesting birds.
• Avoid creating artificial food, shelter or refuge conditions that increase predator activity around retained or rehabilitated habitat.

Rehabilitation actions: Monitoring and success measures

• Monitor surface stability, vegetation cover, weed presence, drainage, predator activity and use by Inland Dotterels after rehabilitation.
• Include daylight and nocturnal observations because the species uses open habitat differently across the day and night.
• Use nearby undisturbed suitable habitat as a reference where possible, and assess whether the rehabilitated area remains open, sparsely vegetated and accessible.
• Set project-specific completion criteria with the ecologist, including stable ground, functioning drainage, controlled weeds, removal of construction hazards and no continuing fauna incidents.
• Submit rehabilitation monitoring results and confirmed species records to the project regulator and relevant state wildlife database where required.
