Sooty Oystercatcher (Haematopus fuliginosus)

The Sooty Oystercatcher is a resident Australian shorebird that lives mainly on rocky coasts, offshore islands, reefs and headlands. It can forage and nest within or beside coastal works areas, where disturbance, access, predators and flooding can affect breeding pairs. It is Vulnerable in New South Wales, Rare in South Australia and Tasmania, and Priority 4 in Western Australia. In Queensland it is near threatened protected wildlife, and interference with its breeding place requires a species management program.

Conservation status

New South Wales, Biodiversity Conservation Act 2016: Vulnerable.

South Australia, National Parks and Wildlife Act 1972: Rare. This listing covers only Haematopus fuliginosus fuliginosus.

Breeding season

The Sooty Oystercatcher is a resident Australian shorebird that breeds mainly from August to January. Breeding may start earlier in southern Australia, with eggs recorded as early as July, and timing can vary between regions and years.

Breeding mode: Solitary territorial pairs. Pairs show high nest-site and mate fidelity and may make multiple nesting attempts in one season.

Clutch size: 1 to 4 eggs, usually 2.

Incubation: 25 to 32 days. Both sexes incubate.

Fledging: Chicks are precocial and can run soon after hatching. Young usually fledge within 5 to 9 weeks.

Post-fledging dependence: Young may remain dependent for 3 to 5 months.

Nest sites: Shallow scrapes or hollows in sand, gravel, shingle, shell or among rocks, usually above the high-tide mark. Offshore islands are commonly used, with occasional mainland nesting.

Age at maturity: Not recorded.

Timing can shift between years and regions, particularly with latitude, weather, tides and storm events, so site checks should be completed before clearing or construction.

  • Breeding and nesting: Breeding is documented from August to January, with the strongest overlap in October to January.
  • Eggs and incubation: Eggs may be present from July in southern Australia, with incubation lasting about 25 to 32 days.
  • Dependent chicks and fledglings: Chicks can move soon after hatching, but may remain dependent for 3 to 5 months and fledge within 5 to 9 weeks.
  • Non-breeding dispersal and local gatherings: Outside the breeding period, pairs may disperse to the mainland and birds may form small gatherings in preferred foraging areas.
  • Foraging and territorial activity: Adults are resident and may use rocky shores, reefs, islands, beaches and estuaries throughout the year.
  • Highest clearing risk: The highest risk is from July to March, when eggs, chicks or recently fledged young may be present, although resident territories and nesting habitat can be affected year-round.

Identification: Appearance

Sooty Oystercatchers are large, dark shorebirds of rocky coastal habitats. They can blend into black rocks, wave-cut platforms and headlands, so listen for calls and scan carefully before starting work.

Adults have an entirely black plumage, a long, strong red to orange-red bill, red eyes and pink to red legs. The sexes look similar, although males generally have a shorter, wider bill and females a longer, more slender bill.

Juveniles are browner and less uniformly black. They have paler or grey-brown legs and a shorter, paler or brown-tipped bill.

Adult length: About 40 to 52 cm

Adult bill: About 5 to 8 cm in the NSW fact sheet

Weight: Up to about 750 g has been recorded

Identification: Calls and similar species

The call is loud, carrying and piping. A loud whistling or piping call may be given before flight, when disturbed or during display. A sharp call can indicate that an intruder is approaching a nest.

The main species likely to be confused with it is the Pied Oystercatcher. Pied Oystercatchers have obvious white in the plumage, while Sooty Oystercatchers are entirely black.

  • Use the whole bird, habitat and call together for identification.
  • Treat an agitated bird, repeated calling or distraction behaviour as a possible sign of a nest or chick nearby.

Identification: Field signs

Look for a shallow scrape or rocky or shell-lined hollow above the tideline. Nests may contain gravel, pebbles, shells, plant fibres or small pieces of debris.

Opened shells and limpets on rocks can indicate a regular feeding area, particularly near breeding territories. Adults may defend nests or chicks with loud calls, directional flights and injured-wing distraction displays.

  • Search from a distance with binoculars or a spotting scope.
  • Do not walk into a suspected nesting area to look for eggs or chicks.
  • Record birds, calls, opened shells, nest scrapes, distraction behaviour and any nearby people, dogs or predators.

Distribution: Australian range

The Sooty Oystercatcher occurs around the Australian coastline and is resident rather than a regular overseas migrant. It is thinly scattered, with stronger concentrations in parts of Victoria and Tasmania and lower densities in the northern part of its southern range.

The species occurs around the coast of all Australian states and territories. It has been mapped in New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria and Western Australia.

In NSW it occurs along the full coastline, using rocky headlands, reefs, offshore islands and other marine littoral habitat. Records include the South Coast, Illawarra, Sydney and the northern coast.

  • Search rocky headlands, islands, reefs, rock platforms, stacks and exposed coastal outcrops.
  • Also check sandy beaches near rocks, reefs, mudflats or other intertidal feeding areas.
  • Check offshore islands and isolated coastal landforms where access is limited and breeding pairs may persist.

Distribution: Subspecies and regional variation

The nominate subspecies, Haematopus fuliginosus fuliginosus, occurs around southern Australian coasts north to about 25 degrees south. The tropical subspecies, Haematopus fuliginosus opthalmicus, occurs around tropical coasts and intergrades with the nominate subspecies where their ranges meet.

The tropical form is relevant to northern coastal projects. The species is considered rare in the north, particularly around the Gulf of Carpentaria.

Distribution: Status relevant to projects

The NSW population is listed as Vulnerable under the NSW threatened species legislation. South Australia and Tasmania list the species as Rare. Western Australia assigns Priority 4, a non-statutory category for rare and near threatened species requiring monitoring.

In Queensland, near threatened animals are protected wildlife. Tampering with a breeding place requires a species management program. The species is also profiled as an EVNT species across its Australian range.

  • Confirm the applicable state or territory requirements before clearing, access, construction or disturbance near coastal habitat.
  • Treat a breeding pair, nest or dependent chick as a high-risk constraint, even where the local listing is not Vulnerable.
  • For NSW projects, use a threatened species assessment and obtain any required approvals before work starts.

Habitat: Landforms and coastal features

Sooty Oystercatchers favour open marine littoral habitat, especially rocky shorelines. On a works site, focus on the interface between rocks, intertidal feeding areas and secure nesting or resting places above the high-tide line.

Typical habitat includes the bases of cliffs and headlands, rock platforms, reefs, outcrops, rock stacks, offshore islands and exposed coastal rocks. The species also uses stony beaches and, less often, sandy beaches near suitable intertidal habitat.

The species can occur within about 50 m of the shoreline in marine littoral habitat. It may occasionally use estuaries.

  • Rocky headlands and wave-cut platforms.
  • Offshore islands, stacks, coral isles and exposed reefs.
  • Stony beaches, steep beaches and points with nearby rocks.
  • Estuary margins where rocky or intertidal feeding habitat is present.

Habitat: Site assessment

Before works begin, inspect the full coastal footprint and nearby shoreline. Include access tracks, laydown areas, temporary fencing, plant parking and areas where people may gather.

Pairs maintain small traditional territories and may use the same area for many years. A site can therefore remain important even when birds are not visible during a single inspection.

  • Map rocky shoreline, islands, reefs, nesting ledges and access points.
  • Check nearby mainland beaches when island pairs may move there outside the breeding season.
  • Inspect at different tide states where practicable, with high tide useful for locating roosting birds and exposed low tide useful for assessing feeding habitat.

Habitat: Habitat condition

Suitable habitat is generally open, with clear views and little disturbance. Coastal development, frequent visitors, dogs, vehicles, vegetation changes and introduced predators can reduce its value.

Retain natural rock, shingle, shell grit and open shoreline where possible. Avoid placing structures or tall screening vegetation where it blocks birds' view of approaching threats.

  • Record existing disturbance, weeds, rubbish, fishing tackle, tracks and predator signs.
  • Include adjacent intertidal habitat in the impact assessment, not just the proposed clearing area.
  • Protect islands and remote headlands from unnecessary access during the breeding season.

Foraging habitat: Feeding places

Foraging is concentrated in the intertidal zone and on rocky surfaces exposed by falling tides. Feeding habitat may extend well beyond the immediate nest area, so assess the shoreline around a proposed work site as a connected area.

The species forages mostly on intertidal rock, reefs, platforms and exposed coastal outcrops. It also feeds above the tideline on beaches and around stranded seaweed, and may use sandy shores near rocks or mudflats.

The recorded foraging range extends up to about 500 m from the nest. Protecting a nest without maintaining access to feeding areas may not protect the breeding pair.

  • Intertidal rock platforms and reef edges.
  • Rocky shoreline below and around headlands.
  • Stranded seaweed and beach margins above the tideline.
  • Nearby sand, mudflat or estuarine areas connected to rocky habitat.

Foraging habitat: Diet and feeding signs

The diet is mainly marine invertebrates, including limpets, periwinkles, mussels, cunjevoi, crustaceans and other hard-shelled animals. The bird picks food from rocks, hammers shells against rocks and prises bivalves open.

Open shells, broken limpet shells and shell fragments around rocks can indicate regular feeding or chick-feeding areas. Feeding sites may be especially concentrated near an active nest.

  • Map shell middens or fresh opened shells near the proposed work area.
  • Avoid moving rocks, removing seaweed or altering intertidal surfaces used for feeding.
  • Keep plant, workers and temporary materials away from feeding areas where birds are repeatedly present.

Foraging habitat: Survey approach

Use a slow shoreline inspection and scan from a distance with binoculars. Record birds at different tidal stages because feeding habitat is exposed as the tide falls, while birds may be concentrated at high-tide roosts.

Where a pair is present, observe from outside its reaction distance. Repeated observations over several days and, where needed, across seasons will provide a better indication of site use than a single visit.

  • Record date, time, tide, weather, number of adults and behaviour.
  • Note feeding, roosting, territorial defence, alarm calls and movement direction.
  • Stop or redesign activities if birds repeatedly leave feeding habitat or show sustained alarm.

Breeding habitat: Nest sites

Sooty Oystercatchers breed as territorial pairs, usually on offshore islands and other secure coastal landforms. Their nests are exposed and can be damaged by people, dogs, vehicles, predators, high tides and construction activity.

Nests are shallow scrapes or rocky or shell-lined hollows in sand, gravel, shingle or among rocks. They are generally above the tideline, including on offshore islands, stacks, remote headlands, points, outcrops and steep beaches.

Nests are usually in bare areas, although wrack may be present. Suitable sites have nearby intertidal feeding habitat and a clear view of approaching threats.

  • Search above the high-tide line and above likely storm surge levels.
  • Check shell grit, pebbles, gravel, rock shelves, shingle and bare ground among coastal rocks.
  • Inspect small islands and isolated headlands before allowing access or starting works.

Breeding habitat: Breeding timing and behaviour

Eggs are laid from late winter to spring. South Coast NSW breeding is recorded from August to January, while a broader beach-nesting reference gives October to January and records eggs as early as July in southern Australia.

Pairs can make several nesting attempts in one season and maintain traditional territories. Both adults incubate the eggs and defend nests and chicks.

  • Usually two eggs are laid, with one to four recorded.
  • Incubation is about 25 to 32 days.
  • Chicks can run soon after hatching and may fledge in 5 to 9 weeks.
  • Post-hatching dependence can last 3 to 5 months.

Breeding habitat: Breeding site survey

Do not enter a suspected nesting area to locate eggs. Watch from a concealed or distant position and use binoculars or a spotting scope. Repeated alarm calls, distraction displays, an adult staying low, or a chick running and hiding can indicate a breeding site.

Once a site is confirmed, mark the location from outside the nesting area and establish a site-specific protection zone. Use the bird's start distance, meaning the distance at which it reacts to an approaching person, to set the minimum buffer.

  • Record adult numbers, nest or chick location, behaviour, tide, weather, predators and nearby disturbance.
  • Inspect known non-colonial nesting sites at least weekly where monitoring is authorised and can be done without causing disturbance.
  • Use remote or distant checks between close inspections.
  • Stop work and seek ecological advice if a nest, chick or strong territorial response is found.

Breeding habitat: Protection during works

Make the protected area as large as practicable. Fencing should be visible, stable and signed, and should not force workers or the public toward the nest or feeding area.

Keep dogs, vehicles, machinery, workers and visitors outside the protection zone. On offshore islands, restrict access during breeding and remove temporary access controls after the breeding season only when the land manager or ecologist confirms they are no longer needed.

  • Use temporary fencing and signs to control people and vehicles.
  • Place electric fencing at least 5 m inside a temporary people-management fence where electric fencing is used.
  • Do not relocate eggs, chicks or nests without approval and specialist advice.
  • Plan works around high tides, storm surges and periods of severe weather.

Sheltering habitat: Likely resting places

Specific Sooty Oystercatcher roost sites are not well documented, but birds need open, secure places close to feeding habitat. During the non-breeding season, pairs may return to the mainland and form small gatherings in preferred feeding areas.

Look for open rocky shorelines, rock platforms, beaches, sand or shingle margins, rock walls and quiet headlands above the high-water mark. Birds need a clear view of approaching people, dogs and predators.

At high tide, shorebirds commonly concentrate at roosts. For Sooty Oystercatchers, inspect elevated rocks, open beaches and shoreline points near intertidal feeding areas.

  • Open rock platforms and exposed ledges.
  • Quiet headlands, points and offshore islands.
  • Sand or shingle beaches above the high-water mark.
  • Estuarine margins or rock walls close to feeding habitat where birds are observed regularly.

Sheltering habitat: Signs of use

Repeated presence of birds at the same open shoreline, especially at high tide or outside the breeding season, indicates a site that may be used for resting or gathering. Record the location even if no nest is present.

Avoid relying on droppings or whitewash as identification signs. The most useful evidence is the bird's presence, repeated use, calls, tracks, feeding remains and response to disturbance.

  • Count birds during high tide and record the tide state.
  • Map roost locations in relation to access tracks, roads, work areas and public use.
  • Record whether birds flush, call, move repeatedly or abandon the site when people or machinery approach.

Sheltering habitat: Managing shelter and roost areas

Keep roosts open and maintain an unobstructed view. Avoid stockpiling materials, parking machinery, placing temporary buildings or installing screening close to regularly used resting places.

Use signs, fencing and controlled access where a roost is beside a construction area or busy beach. Set the buffer from observed bird responses and obtain ecological advice where repeated disturbance occurs.

  • Keep workers, dogs, vehicles and visitors away from roosts, particularly at high tide.
  • Do not remove natural rocks, shell grit or shoreline features used by resting birds.
  • Retain nearby feeding habitat and safe movement routes between roosts, nests and intertidal areas.

Threats: People, vehicles and dogs

Most risks on works sites come from disturbance, loss of access, direct damage to nests or chicks, and changes to coastal processes. Controls should be stronger around active nests, dependent chicks, offshore islands and sites supporting a listed population.

People walking into nesting areas can cause adults to leave eggs or chicks exposed. Dogs, especially off leash, may trigger repeated alarm responses, prolonged flushing and chick hiding. Vehicles and machinery can crush eggs or chicks and damage scrapes, tracks and feeding habitat.

Beach users, island visitors, four-wheel-drive vehicles, horses, stock and construction traffic should be excluded from confirmed breeding and roost areas.

  • Fence and sign active nest and chick areas before works start.
  • Keep access tracks, plant movements and laydown areas away from nests, feeding sites and roosts.
  • Use a fauna spotter catcher or ecologist to check exclusion zones before daily works.
  • Stop work if an adult shows sustained alarm or distraction behaviour.

Threats: Predation and entanglement

Eggs and chicks may be taken by rats, foxes, cats, ravens, gulls, raptors, goannas and other native or introduced predators. Offshore island populations can be particularly exposed to introduced rats.

Discarded fishing line, hooks and other tackle can injure or kill adults and chicks. Rubbish can also attract predators or obstruct movement.

  • Inspect nest areas for predator tracks, scats, burrows and other signs.
  • Secure food waste and remove rubbish from work sites and access routes.
  • Use an approved predator control program where required, particularly on offshore islands.
  • Remove fishing line and hooks only where this can be done safely and without entering a protected nest area.

Threats: Tides, storms and coastal change

Nests near the high-tide line can be inundated by king tides, high tides, storms and large swells. Spring storms and big seas can be especially damaging on offshore islands.

Reclamation, dredging, filling, shoreline alteration, pollution, beach cleaning, driftwood removal, dune stabilisation and weed invasion can reduce breeding or feeding habitat.

  • Check high-tide marks, storm-surge exposure and recent erosion before locating temporary works.
  • Avoid placing materials or structures where they redirect water or remove natural shelter.
  • Retain shell, gravel, shingle, rock and wrack features used for nests and feeding.
  • Include indirect impacts on nearby intertidal habitat in the works assessment.

Threats: Disturbance from construction

Noise, lighting, repeated vehicle movements and workers near a nest can interrupt incubation and chick feeding. Even short visits may be harmful if they cause repeated flushing or separate chicks from adults.

For Vulnerable NSW sites and other listed populations, use a precautionary approach and obtain project-specific ecological and regulatory advice before clearing or construction.

  • Complete pre-clearance and coastal habitat surveys before mobilisation.
  • Schedule noisy or high-traffic work outside the breeding period where practicable, while recognising that resident pairs may be present year-round.
  • Maintain buffers based on observed start distance and behaviour, not just the edge of the mapped work area.
  • Keep daily monitoring records and review controls if birds change behaviour or abandon an area.

Survey methodology: 1. Desktop assessment

Sooty Oystercatchers are resident coastal birds. They can be difficult to detect on dark rock, so surveys should cover rocky shorelines, offshore islands, headlands, reefs, beaches near rocks and nearby estuarine habitat.

Map rocky intertidal shorelines, rock platforms, reefs, headlands, offshore islands, exposed stacks, stony beaches and beaches near mudflats or rocks.

Identify known breeding territories, nest sites, foraging areas, high-tide roosts, marine park zones, conservation reserves and access routes.

Check whether the proposal could affect a breeding place, habitat used by a listed population, or a site in a state or territory where the species is listed or otherwise protected.

Typical habitat: Rocky shores, headlands, reefs, rock platforms, offshore islands, exposed stacks and some sandy beaches.

Foraging range: Adults may forage up to 500 m from the nest.

  • Review recent records from wildlife atlases, land managers, local shorebird groups and previous ecological surveys.
  • Treat island and headland records as particularly relevant because these areas support breeding and refuge habitat.
  • Plan surveys around tides, access constraints, wave exposure and the need to observe from land or boat without landing near birds.

Survey methodology: 2. Field detection and timing

Survey rocky shorelines and islands at low tide or as the tide recedes, when birds are feeding on exposed intertidal surfaces. Also check high-tide roosts when birds are concentrated and easier to count.

Prioritise the breeding period. Breeding is generally from late winter or spring to summer. In southern Australia, breeding activity may begin in July, and October to January is a recognised breeding period in South Australia.

Use slow, quiet searches from a distant vantage point. Scan dark rock, wrack, gravel, shingle and shell-covered areas for birds, alarm calls, territorial behaviour, eggs and chicks.

Identification: A stocky, entirely black shorebird with a long red to orange-red bill, red eyes and pink to red legs.

Useful calls: A loud piping or whistling call, including a carrying call before flight and sharper alarm calls near a nest.

  • Use binoculars or a spotting scope before moving closer.
  • Avoid walking onto suspected nesting habitat to locate eggs.
  • Repeat visits at different times of day over several days where detection is difficult or a breeding territory is suspected.
  • Use additional seasonal visits where the site may support non-breeding gatherings or where weather and tides limit detection.
  • Record storm, swell, tide, wind, temperature, visibility and recent disturbance conditions.

Survey methodology: 3. What to record

Record every observation on a site plan or georeferenced field form. Separate adults, juveniles, fledglings, eggs and chicks where possible.

Map nests, likely territories, feeding areas, roosts, access points, tracks, dogs, vehicles, predators, fishing gear and other disturbance sources.

Record whether birds are feeding, roosting, displaying, incubating, defending territory, carrying food or tending chicks.

  • Record the number of birds, pairs, active nests, eggs, chicks and fledglings.
  • Photograph habitat and signs from a distance, without approaching an active nest.
  • Record predator signs, including rat, fox, cat, dog, raven, gull and raptor activity where present.
  • Record the observer, date, time, tide, weather, survey duration, route, vantage points and visibility.
  • Report uncertainty clearly, including birds that could not be assigned to a nest or territory.

Before habitat disturbance: 1. Approvals, listings and permits

Avoidance is the preferred outcome for a vulnerable or otherwise listed shorebird. Plan works around breeding activity, retain rocky and open coastal habitat, and obtain jurisdiction-specific advice before entering an offshore island, headland or active nesting area.

Have the project ecologist check the current legal status in every jurisdiction affected by the works. The species is Vulnerable in New South Wales, an EVNT species in the project context, Rare in South Australia and Tasmania, and Priority 4 in Western Australia. Queensland treats near threatened animals as protected wildlife, and tampering with a breeding place requires a species management program.

Assess whether the action needs an EPBC Act referral or other Commonwealth approval. Do not assume that an absence from a migratory shorebird list removes all project obligations. Confirm the current listing and referral position with the relevant regulator.

Obtain state or territory permits, protected wildlife approvals, scientific licences, marine park approvals, island access approvals and animal ethics or rehabilitation permissions where they apply.

NSW status: Vulnerable under the NSW threatened species framework.

Other status context: Rare in South Australia and Tasmania, Priority 4 in Western Australia, and protected wildlife provisions apply to near threatened animals in Queensland.

  • Document the legal advice, approval conditions and responsible approval holder before mobilisation.
  • Confirm whether clearing, construction, access, lighting, noise, vessel movements or disturbance could affect a breeding place or roost.
  • Do not alter, damage or obstruct a nest or breeding place without written approval and a regulator-agreed method.

Before habitat disturbance: 2. Pre-clearance survey and work timing

Complete a targeted survey before clearing, earthworks, access construction, blasting, piling, shoreline works or vessel activity. Survey all habitat within and near the work area, including islands, rocky margins, exposed reefs, stony beaches and adjoining foraging habitat.

Schedule the main disturbance outside the local breeding period wherever practicable. For southern sites, plan around late winter to summer breeding, with particular care from August to January. Confirm local timing because breeding can start as early as July in southern Australia.

Allow extra time after storms, high tides and large swells. Nest sites near the high-tide mark can be lost or birds can move to less obvious sites.

  • Use a qualified ecologist familiar with coastal shorebirds.
  • Search from outside suspected nesting areas and use binoculars or a spotting scope.
  • Treat territorial adults, repeated alarm calls, distraction displays, nest material, eggs, chicks or adults carrying food as evidence requiring further assessment.
  • Do not begin works solely because no nest was seen during one visit.

Before habitat disturbance: 3. Buffers, exclusion and induction

Establish a no-entry area around each confirmed or suspected nest, chick-rearing area and repeatedly defended territory. Set the buffer using the birds’ start distance, which is the distance at which they react to an approaching person or vehicle.

Use 100 m as a general starting point for beach-nesting bird protection where a site-specific start distance has not been established. Increase the buffer if birds alarm, leave the nest, stop feeding, repeatedly call or show distraction behaviour.

Fence the largest practical area around the habitat. Keep fencing visible, install clear signs and place electric fencing at least 5 m inside a temporary people-management fence if electric fencing is approved and needed.

  • Keep people, dogs, vehicles, plant, vessels and contractors outside the exclusion area.
  • Remove temporary fencing after the breeding season only when the ecologist and land manager confirm that it is no longer needed.
  • Induct all workers on identification, exclusion boundaries, access routes, stop-work powers, reporting and the prohibition on handling birds or eggs.
  • Use a spotter catcher or fauna ecologist to check the exclusion area at the start of each shift.

During habitat disturbance: 1. Sequential clearing and spotter authority

Work should proceed in a controlled sequence with a clear stop-work process. Sooty Oystercatchers defend nests strongly, but a quiet bird or hidden chick does not mean the area is clear.

Start with the lowest-risk area and work towards the retained habitat, leaving escape routes and all exclusion zones undisturbed. Do not isolate an island, shoreline, nest site or foraging area by removing access to adjoining habitat.

Give the fauna spotter catcher authority to stop work immediately. Stop for birds, eggs, chicks, active nests, fresh nest scrapes, alarm behaviour, distraction displays, injured animals, entangled animals or unexpected habitat use.

Keep plant stationary until the ecologist has assessed the finding and released the area.

  • Use a pre-start briefing and mark exclusion zones on the ground and project plans.
  • Maintain a slow work front where habitat is close to the high-tide line or rocky shore.
  • Prevent workers and vehicles from crossing shell, gravel, shingle or wrack areas that could contain a shallow scrape.
  • Suspend works during unsafe swell, storm surge or tide conditions where the approved controls cannot be maintained.

During habitat disturbance: 2. Active breeding places, roosts and gatherings

If an active nest, chick, defended territory or breeding place is found, stop work and withdraw along the access route. Keep people quiet and move beyond the bird’s start distance.

Do not touch eggs, chicks, nests or adults. Do not relocate a nest or alter the substrate. Refer the finding to the project ecologist, land manager and relevant regulator before work resumes.

If a roost or gathering is found, stop encroaching activity and establish a buffer that prevents repeated flushing. Maintain an unobstructed view and access to adjoining foraging habitat.

  • Mark the location from a distant vantage point rather than entering the nesting area.
  • Record the species, number of birds, behaviour, nest or chick evidence, coordinates, photographs, disturbance source and time of the finding.
  • Keep dogs, visitors, vessels, plant, lighting and noisy activities outside the agreed buffer.
  • Use an approved species management program or regulator-approved method where Queensland breeding-place provisions apply.

During habitat disturbance: 3. Injured or entangled animals

Keep people and dogs away from an injured, exhausted or entangled bird. Reduce noise and visual disturbance while waiting for the authorised wildlife carer or veterinarian.

Do not chase, catch, feed, water or release the bird unless directed by an authorised person. Fishing line and hooks can injure adults and chicks, so isolate the area and arrange safe removal by trained personnel.

If capture is required, use only people authorised under the relevant permit and animal welfare procedures.

  • Contact the project ecologist, wildlife rescue service, land manager and relevant wildlife authority.
  • Record the location, condition, apparent cause, photographs, people involved and time of transfer.
  • Treat an entangled bird as a project incident, even if it is released on site.

During habitat disturbance: 4. Daily records and stop-work close-out

Keep a daily fauna register for every shift. The register should show that controls were applied and should support later reporting.

The supervisor should confirm that exclusion fencing, signs, access controls and buffers remain intact before work restarts each day.

  • Record weather, tide, swell, works undertaken, observers, bird counts, nests, chicks, roosts, disturbance, incidents and corrective actions.
  • Record every stop-work event, who made the decision, how long work stopped and who authorised recommencement.
  • Photograph damaged fencing, tracks, vehicles or other disturbance before repairs where this can be done without approaching birds.
  • Escalate repeated alarm behaviour, nest abandonment, injury, mortality or buffer breaches to the project manager and regulator contact.

After habitat disturbance: 1. Post-clearance inspection

Post-clearance checks should confirm that no breeding place, chick or roost has been overlooked and that controls remain effective. Review incidents promptly so the next work stage is safer.

Inspect the completed work area, retained habitat, access routes and exclusion fencing from a distant vantage point. Check for birds returning to a territory, chicks using disturbed ground, damaged nests, exposed eggs, entanglement hazards and new predator or dog activity.

Repeat checks during the breeding period where works remain near nesting habitat. Use binoculars or a spotting scope and avoid entering the retained nesting area.

  • Check the area after high tides, storms, large swells and major changes to beach or rock conditions.
  • Confirm that plant, rubble, spoil, fencing wire, cable, packaging and fishing material have been removed from habitat.
  • Check that lighting, noise, access and vehicle controls match the approved method.
  • Record adult and juvenile counts, active nests, eggs, chicks, fledglings and observed behaviour.

After habitat disturbance: 2. Monitoring and reporting

Set monitoring effort according to the listing, the approval conditions, the sensitivity of the site and the scale of the works. A vulnerable NSW population and an active breeding place require more oversight than a short, distant activity with no habitat disturbance.

Use repeat visits at suitable tides and times of day. Continue until the ecologist and regulator agree that the risk has ended or the breeding attempt has finished.

  • Compare observations with the pre-work baseline.
  • Report nest success, chick survival where observable, adult presence, disturbance events, injuries, mortality and habitat changes.
  • Submit records to the project manager, land manager and relevant authority where required by approval conditions.
  • Provide final mapping of retained habitat, exclusion areas, incidents and corrective actions.

After habitat disturbance: 3. Relocated animals and incident review

Sooty Oystercatchers should not be moved as a routine mitigation measure. If an authorised wildlife professional has relocated an injured bird, record the release site, condition, authority, date and follow-up requirement.

Review every nest loss, injury, mortality, repeated disturbance event, fence breach and unplanned work stoppage before the next work stage.

  • Identify the direct cause and any contributing factors, such as access, lighting, dogs, plant movement, predators, fishing line, swell or inadequate fencing.
  • Amend the method statement, induction, buffer, work timing or supervision before restarting similar work.
  • Share lessons with contractors, spotter catchers, land managers and the approval holder.
  • Keep all permits, photographs, field sheets, veterinary records and correspondence in the project environmental file.

Rehabilitation actions: 1. Restore nesting and foraging habitat

Rehabilitation should restore open coastal habitat, natural substrate and safe access to intertidal food. Sooty Oystercatchers do not use nest boxes or bat boxes, so replacement structures are generally unsuitable.

Reinstate natural rock, gravel, shingle, shell and sand surfaces where these were temporarily disturbed. Keep nest surfaces open and above the high-tide line, while allowing adults access to nearby intertidal feeding areas.

Avoid creating steep edges, loose netting, exposed wire, deep pits or vehicle ruts that can trap chicks or adults.

Remove temporary roads, hardstand, spoil, barriers and materials that block movement between nesting habitat, feeding areas and safe roosts.

  • Use local substrate and natural contours where practicable.
  • Retain rocky shorelines, reefs, headlands, offshore island habitat and open sightlines.
  • Keep tall structures, dense vegetation and unnecessary lighting away from roosting and nesting areas.
  • Design drainage so that it does not concentrate runoff across nests or create unstable, flooded surfaces.

Rehabilitation actions: 2. Artificial nest sites and roost features

Do not install nest boxes or bat boxes for this species. Sooty Oystercatchers nest in shallow scrapes or hollows on sand, gravel, shingle, shell, rock or coral rubble.

Consider an artificial open nest site only where a suitably qualified coastal ecologist and the land manager confirm that natural habitat cannot be restored and the regulator accepts the design. Match the local substrate, elevation, drainage, open view and access to intertidal foraging habitat.

Do not place an artificial site close to people, dogs, roads, lighting, structures that conceal predators or areas exposed to avoidable disturbance.

  • Use a small, shallow scrape or substrate patch rather than a box or enclosed structure.
  • Keep the design above the high-tide mark and assess storm surge and large swell risk.
  • Do not attract birds to a construction area or use artificial sites as a substitute for protecting natural breeding habitat.
  • Monitor any approved artificial site through the breeding period and remove failed or hazardous materials.

Rehabilitation actions: 3. Weeds, predators, water and lighting

Control weeds where they close open sightlines, cover nesting substrate or reduce access to rocky and intertidal habitat. Use methods that do not disturb active nests or contaminate feeding areas.

Manage introduced predators, particularly rats on offshore islands, in accordance with approved wildlife and biosecurity procedures. Do not leave food, waste or materials that attract predators.

Keep water quality and drainage stable. Prevent sediment, fuel, concrete washout, litter and other contaminants from reaching intertidal feeding habitat.

  • Use low-impact weed control and stage works outside active breeding areas where possible.
  • Remove fishing line, hooks, plastic, wire and other entanglement hazards.
  • Use shielded, low-spill lighting and switch off unnecessary lights near shore, islands, nests and roosts.
  • Keep lighting directed away from the sea, nesting substrate and flight paths.

Rehabilitation actions: 4. Long-term monitoring

Monitor restored areas for recolonisation, breeding attempts, chick use, predator activity, weed regrowth, erosion and disturbance. The monitoring period should match approval conditions and the time needed for the habitat to become stable.

Use the same mapped points and recording fields as the pre-work survey so changes can be assessed.

  • Check restored nesting surfaces before and during the breeding period.
  • Record adults, pairs, nests, eggs, chicks, fledglings, foraging birds and roosting birds.
  • Inspect after high tides, storms and large swells for erosion or inundation.
  • Repair failed fencing, drainage, substrate or access controls promptly, without entering an active nesting area.
  • Retain monitoring results in the project file and provide them to the land manager and relevant regulator where required.
