Spectacled Monarch (Symposiachrus trivirgatus)

The Spectacled Monarch is a small insectivorous forest bird found mainly in coastal and near-coastal eastern Australia. Dense rainforest, moist forest, wet gullies, riparian vegetation and mangroves can provide habitat on clearing and construction sites, including habitat used during movement and breeding. It is least concern in Australia but is listed as migratory under the EPBC Act, and is a special least concern animal in Queensland, where tampering with its breeding places requires a high risk species management program.

Conservation status

Commonwealth, EPBC Act 1999: Listed migratory. Listed under the Bonn Convention. Listed migratory species are a matter of national environmental significance, so a significant impact needs referral.

Queensland, Nature Conservation Act 1992: Special least concern. A least concern bird covered by an international migratory bird agreement. Tampering with its breeding place needs a high risk species management program.

Migration and breeding season

The Spectacled Monarch is present in Australia year round in some northern areas, but movement varies between subspecies and regions. Breeding has been recorded from September to April, with October to February the main breeding period reported for Queensland.

Breeding mode: Egg laying in a deep cup-shaped nest, usually built in a vertical fork of a tree, sapling or shrub, or among hanging vines.

Clutch size: Usually two eggs.

Incubation: 15 to 18 days, with the female performing most of the incubation.

Nestling and fledging period: Nestlings fledge after 17 to 20 days.

Parental care: Both parents feed the nestlings. Newly fledged young are fed for several days, and one young was recorded as being cared for for 5 to 6 weeks after fledging.

Age at maturity: Not recorded.

Nest placement: Nests are generally 1 to 6 m above ground and are often near watercourses, wet gullies or other waterside vegetation.

Seasonal timing can vary between years and regions, with Cape York birds often resident or partly migratory and movements of some Queensland subspecies poorly understood.

  • Breeding and nesting in Australia: Breeding has been recorded from September to April, with the strongest general activity from October to February.
  • Eggs, nestlings and dependent young: Eggs, nestlings and recently fledged young may be present while breeding is underway, especially in spring and summer.
  • Southward arrival and passage: Southward movement occurs in austral autumn, although the exact passage timing is not well defined for this species.
  • Non-breeding presence in Australia: Some birds remain in Australia outside the breeding season, while some southern and Wet Tropics birds may move north or winter in New Guinea.
  • Northward departure and passage: Northward movement occurs in austral spring, but resident Cape York birds and other regional differences make the pattern uneven.
  • Highest clearing risk: Clearing and earthworks are most likely to harm nests, eggs, nestlings or dependent young from September to April, particularly from October to February.

Identification: Appearance

The Spectacled Monarch is a small, active songbird that moves through dense foliage. It can be difficult to detect in thick vegetation, so listen for calls and watch inner foliage rather than only open edges.

Adults are blue-grey or slate-grey above, with pale underparts. The black face mask extends across both eyes and the chin, giving a distinctive clover-leaf pattern. The throat and upper breast are rich rufous-orange, and the black tail has white outer tips.

Immature birds lack the black face mask and have a grey throat. The northern Cape York form has a rufous upper breast that is sharply separated from more extensive white underparts.

Body length: 15 to 16.5 cm

Key markings: Black face mask, rufous throat and upper breast, white tail corners

Identification: Calls and behaviour

Australian birds give raspier whistled notes. Calls are also described as harsh buzzes and rattles. The species moves actively through foliage and may fan its tail, showing the white tail tips.

There is no echolocation. Use repeated listening stops in dense vegetation, especially where visibility is limited.

  • Check the inner foliage and shaded lower to middle forest levels.
  • Record the direction of calls before entering dense habitat.
  • Treat a brief call or fleeting bird as a useful fauna record, even without a photograph.

Identification: Similar species and field signs

A specific similar-species comparison is not established in the available species profiles. Confirm records using the combination of the black mask, rufous throat and breast, slate-grey upperparts and white tail corners.

Droppings, whitewash, stains and odour are not reliable field signs for this species. A nest is a more useful breeding sign and is described under breeding habitat.

  • Look for repeated use of the same dense vegetation rather than relying on a single sighting.
  • Photograph the bird, habitat and direction of movement where safe to do so.
  • Have uncertain records checked by an experienced bird observer or ecologist.

Distribution: Australian range

The Spectacled Monarch is largely confined to north-eastern and eastern Australia, with its strongest distribution along the coast and eastern slopes. Some populations are resident, while others move within Australia or to New Guinea.

In Queensland, the species occurs along the east coast, on offshore islands, on the eastern slopes of the Great Dividing Range, on Cape York Peninsula and in the Torres Strait. It ranges from the Cape York region south to the New South Wales border and approximately Mackay for some northern subspecies.

In New South Wales, it occurs along the coast and eastern slopes to the northern Hunter Region, with occasional records farther south around Newcastle, the Central Coast and Sydney. It is a vagrant to Groote Eylandt in the Northern Territory.

  • Queensland, including Cape York Peninsula, the Wet Tropics, coastal forests and Torres Strait islands.
  • New South Wales, mainly the coast and eastern slopes.
  • Northern Territory, with vagrant records from Groote Eylandt.
  • Victoria is included in Australian mapping for the species, but the established range described for the species is concentrated in north-eastern and eastern coastal regions.

Distribution: Subspecies and movement

The southern subspecies occurs from the Proserpine area south along the east coast to just south of Sydney. Some individuals may move to northern Queensland or New Guinea outside the breeding season.

The Wet Tropics subspecies occurs from the Yarraden area through the Queensland coast near Cairns to approximately Mackay. Its movements are poorly understood. The Cape York subspecies is considered resident or partly migratory on Cape York Peninsula.

Distribution: Overseas range

The species or its recognised subspecies also occur in southern New Guinea and on islands in the Torres Strait. Broader taxonomic treatments include records from parts of the Moluccas, Timor and the Lesser Sunda Islands.

Habitat: Preferred vegetation

Look for dense vegetation with a humid understorey. On works sites, habitat may be retained in narrow strips, gullies, creek lines, wet forest remnants, mangroves and connected vegetation outside the disturbance footprint.

The main habitats are rainforest, moist forest and wet sclerophyll forest. The species also uses dense vegetation in mangroves, drier forest, woodlands, parks and gardens.

  • Rainforest and subtropical or tropical moist forest.
  • Moist or wet sclerophyll forest, especially with dense understorey.
  • Wet gullies and waterside vegetation.
  • Riparian vegetation and mangroves.
  • Dense woodland understorey and other connected vegetation.

Habitat: Site features to check

Prior to clearing, inspect creek lines, drainage depressions, wet gullies, vine thickets, forest edges with dense understorey and vegetation around water. Retained trees and shrubs can still provide habitat when the surrounding area is disturbed.

The species may use habitat in the broader landscape even when a small project area does not support a large population. Assess connections to adjacent rainforest, reserves, riparian corridors and coastal vegetation.

  • Map dense vegetation within and beside the work area.
  • Identify vegetation that links gullies, creek lines or forest remnants.
  • Mark mangroves and waterside vegetation as fauna-sensitive areas.
  • Check whether clearing could isolate a patch of dense habitat.

Habitat: Important habitat

For EPBC assessment, important habitat includes dense vegetation used by the species, mainly rainforest, moist forest and wet sclerophyll forest. Mangroves, drier forest and woodlands can also be relevant where they provide dense cover or movement habitat.

An action may have a significant impact if it substantially modifies, destroys or isolates important habitat, or allows a harmful invasive species to become established there.

National habitat threshold: 210 ha represents the 0.1% threshold for the species, while 2,100 ha represents the 1% threshold.

Management use: Smaller areas can still require investigation where they form part of a movement corridor, breeding area or connected patch.

Foraging habitat: Feeding areas

The Spectacled Monarch is an insectivore that searches through foliage for prey. Protect dense lower and middle vegetation, not just large canopy trees, when planning clearing and access routes.

The species takes insects across a range of forest levels, most often around 5 to 15 m above the ground. It usually stays within inner foliage rather than feeding only along exposed edges.

It may forage in rainforest, moist or wet sclerophyll forest, riparian vegetation, mangroves, drier forest and woodland with suitable cover.

  • Dense shrubs and saplings.
  • Vines and tangled understorey.
  • Inner foliage of retained trees.
  • Vegetation along creek lines and wet gullies.
  • Mangrove foliage and other densely vegetated coastal areas.

Foraging habitat: Foraging behaviour

The Spectacled Monarch commonly forages in pairs. It sits and waits for prey, then captures insects by gleaning from foliage or by short sallies. It may also forage on tree trunks, vines and foliage below the canopy.

  • Use quiet observation periods before clearing begins.
  • Search shaded vegetation at several heights rather than only the ground layer.
  • Avoid removing connected understorey where it can be retained safely.
  • Include adjacent habitat in the assessment because birds can move beyond the project boundary.

Foraging habitat: Construction controls

Vegetation clearing, dust, noise and changed drainage can reduce feeding opportunities. Retain dense vegetation where practicable, stage clearing towards already disturbed areas and prevent sediment, weeds and other pollutants from entering wet habitat.

  • Keep machinery and laydown areas out of retained riparian and mangrove vegetation.
  • Control invasive plants and prevent their spread into important habitat.
  • Use fauna spotter-catchers during clearing and grubbing.
  • Stop work and reassess if repeated sightings indicate regular use of the area.

Breeding habitat: Nest sites

Breeding has been recorded from September to April. During this period, treat dense vegetation near water and suitable forks in trees, saplings, shrubs or vines as potential breeding habitat until checked by a qualified person.

The nest is a deep cup. It is usually placed in a vertical fork of a tree, sapling or shrub, or among hanging vines. Nests are often near watercourses or other waterside vegetation.

Reported nest height varies from 1 to 6 m above the ground. One description gives 1 to 4 m for a northern form.

Nest form: Deep cup-shaped nest

Nest materials: Fine bark, plant fibres, moss and spider web or spider cocoons

Nest height: Usually 1 to 6 m above ground

  • Inspect vertical forks in trees, saplings and shrubs.
  • Check hanging vines and dense vegetation near creek lines or other water.
  • Search from ground level before machinery enters the area.
  • Do not disturb a suspected nest while attempting to obtain a closer view.

Breeding habitat: Breeding signs

A nest, adults carrying food, repeated alarm calls or adults repeatedly visiting one small area can indicate active breeding. Both parents feed the nestlings, and fledged young may remain dependent for several weeks.

Typical clutch: Usually two eggs

Incubation: 15 to 18 days

Fledging period: 17 to 20 days

  • Mark the location of any suspected nest from a safe distance.
  • Record adult movements and the direction of approach and departure.
  • Keep workers, vehicles and machinery away while the breeding status is assessed.
  • Follow the approved species management program and project environmental management plan.

Breeding habitat: Queensland breeding-place requirements

In Queensland, the Spectacled Monarch is a special least concern animal because it is a least concern bird covered by the Bonn Convention. Tampering with its breeding place requires a high risk species management program.

  • Before clearing, confirm whether a breeding place is present or likely to be present.
  • Use a fauna spotter-catcher for clearing and grubbing work as required by the project controls.
  • Stop work if an active nest or dependent young are found.
  • Apply the relevant Queensland approval and species management requirements.

Sheltering habitat: Cover to retain

Specific night roost structures and roost group sizes are not established for the Spectacled Monarch. For site management, assume that dense foliage, rainforest understorey and sheltered waterside vegetation may provide resting and cover habitat.

Retain dense shrubs, vines, saplings, understorey and foliage in rainforest, wet forest, riparian areas, mangroves and woodland. These features can provide cover between feeding movements and during passage.

  • Dense understorey in gullies and creek corridors.
  • Vine thickets and foliage beneath the canopy.
  • Mangrove and other waterside vegetation.
  • Connected vegetation between larger forest patches.

Sheltering habitat: Roost information

No defined roost type, roost height or roost group size is available for this species. Do not assume that a small patch is unused because no roost is visible during a daytime inspection.

  • Avoid unnecessary night works beside dense habitat during movement periods.
  • Direct artificial lighting away from retained vegetation and waterways.
  • Limit removal of vegetation outside the approved footprint.
  • Keep stockpiles and temporary access routes away from sheltering habitat.

Migration and seasonal presence: Seasonal presence in Australia

The Spectacled Monarch is listed as migratory under the EPBC Act. Southward movement occurs in austral autumn and northward movement occurs in austral spring, but exact arrival and departure months are not established for the species.

The species breeds in Australia from about September to April in recorded breeding areas. Some birds move north after breeding, while other populations, particularly on Cape York Peninsula, may remain resident or partly migratory.

The southern subspecies may move to northern Queensland and New Guinea outside the breeding season. The Wet Tropics subspecies may move within Queensland or winter in New Guinea. Movements of this subspecies are poorly understood, and the Cape York subspecies is considered resident on Cape York Peninsula.

  • Austral autumn, likely period for southward migration.
  • Austral spring, likely period for northward migration.
  • Spring and summer in southern Australia, an appropriate period for surveys in breeding habitat.
  • September to April, recorded breeding period.

Migration and seasonal presence: Passage habitat

Dense vegetation used during migration passage should be considered important regardless of the number of birds recorded during a survey. Suitable passage habitat can include rainforest, moist forest, wet sclerophyll forest, mangroves, riparian vegetation and other dense woodland.

  • Survey connected vegetation, not only known breeding sites.
  • Consider habitat on both sides of the project boundary.
  • Look for movement corridors along creek lines, gullies, coastal vegetation and forest edges.
  • Use standardised timed survey periods during migration assessments.

Migration and seasonal presence: EPBC project triggers

The species is a matter of national environmental significance under the EPBC Act. An action likely to have a significant impact on the Spectacled Monarch, including substantial modification, destruction or isolation of important habitat, may require referral.

Ecologically significant population proportion: 6,500 birds at 1%, and 650 birds at 0.1%.

Mortality threshold: 650 birds at 1%, and 65 birds at 0.1%.

  • Assess clearing and construction impacts on habitat used for breeding, feeding and passage.
  • Investigate proposals approaching the 0.1% habitat threshold with targeted surveys.
  • Treat predicted annual mortality or breeding-cycle disruption at or above the applicable 1% threshold as a serious potential impact.
  • Seek specialist advice where habitat loss, isolation, invasive species or repeated records are involved.

Threats: Vegetation clearing and habitat loss

The species is generally common and considered secure across its Australian range, but clearing can still remove local habitat and breeding places. Manage vegetation, water, weeds, pests, noise and lighting together across the work area and adjoining habitat.

Removing rainforest, moist forest, wet sclerophyll forest, mangroves, riparian vegetation or dense understorey can remove feeding, sheltering, passage and breeding habitat. Small patches may also become isolated from nearby habitat.

  • Minimise the clearing footprint.
  • Avoid unnecessary removal of understorey and vines.
  • Fence retained habitat before machinery arrives.
  • Rehabilitate disturbed edges with locally appropriate native vegetation.

Threats: Breeding-place disturbance

Tree felling, grubbing and earthworks can injure or kill birds, destroy nests and disrupt adults feeding young. The risk is higher during the recorded breeding period from September to April.

  • Complete pre-clearance checks by a suitably qualified fauna worker.
  • Use a fauna spotter-catcher during clearing and grubbing.
  • Stage clearing and stop work if an active nest or dependent young are found.
  • Apply Queensland species management requirements where a breeding place may be affected.

Threats: Noise, lighting and construction activity

Construction noise can alter feeding behaviour and may cause birds to avoid otherwise suitable habitat. Sudden loud noise and night lighting can also disturb birds using dense vegetation near the work area.

  • Keep noisy activities away from retained habitat where practicable.
  • Direct lighting away from rainforest, riparian vegetation, mangroves and forest edges.
  • Avoid unnecessary night works beside dense habitat.
  • Record repeated avoidance or disturbance and adjust controls.

Threats: Weeds, pests, pollution and changed drainage

Habitat can be degraded by invasive plants, pest animals, pollution and changes to the water regime. These pressures can reduce dense cover and the insect prey available in rainforest, wet forest, mangroves and riparian areas.

  • Control weeds before they spread into retained habitat.
  • Prevent sediment, chemicals and other pollutants from entering waterways and wetlands.
  • Manage black rats and other pest animals where relevant to the site.
  • Maintain natural drainage and protect wet gullies and waterside vegetation.

Survey methodology: 1. Desktop assessment

Survey for Spectacled Monarchs should focus on dense vegetation, especially rainforest, moist or wet sclerophyll forest, riparian vegetation and mangroves. The species is small, active and often keeps to inner foliage, so quiet observation and repeated visits are more useful than a single rapid inspection.

Review recent records, vegetation mapping, watercourses, rainforest remnants, mangroves and other dense vegetation before finalising the clearing plan. Consider both breeding habitat and habitat used during migration passage.

Habitat focus: Rainforest, moist forest, wet sclerophyll forest, riparian vegetation, mangroves, drier forest and woodlands

Foraging height: Usually low to middle forest levels, commonly 5 to 15 m above ground

  • Map habitat that connects larger forest or riparian areas.
  • Check whether the site is within the known eastern or north-eastern Australian range, including coastal, near-coastal and Wet Tropics areas.
  • Identify potential breeding trees, saplings, shrubs and hanging vines, particularly near water.
  • Check whether the proposed action could affect 210 ha or more of important habitat, or 2,100 ha or more at the higher significance threshold. Smaller areas can still require further investigation where habitat quality is high or the site is used during passage.

Survey methodology: 2. Field detection

Use quiet searches and fixed observation points along forest edges, internal tracks, gullies and watercourses. Look and listen for birds moving through inner foliage, often in pairs.

Diet: Primarily insects and other arthropods

Foraging behaviour: Perches and waits for prey, then gleans or sallies from inner foliage

  • Search foliage, vines, tree trunks and lower to middle canopy levels.
  • Allow time for birds to move through dense vegetation rather than relying only on brief visual checks.
  • Record sightings of adults, juveniles, pairs, territorial behaviour, nest material, carrying food or repeated visits to one location.
  • Use experienced observers who can distinguish the Spectacled Monarch from other small monarch flycatchers and confirm records with photographs or detailed field notes where possible.

Survey methodology: 3. Timing and survey effort

Survey during calm weather and good visibility, avoiding heavy rain and strong wind. Repeat visits are appropriate where habitat is dense, the species is likely to be present, or clearing overlaps with breeding or passage periods.

Breeding period reported for the species: September to April

Migration direction: Southward in austral autumn and northward in austral spring

  • In southern Australia, survey breeding habitat during spring or summer.
  • In Queensland, give particular attention to the September to April breeding period described for the species, with October to February also reported for some populations.
  • Use autumn and spring surveys to consider migration passage, including birds moving south in autumn and north in spring.
  • Survey more than once where a single visit may miss a quiet or mobile bird. Match the number and timing of visits to the size, complexity and risk of the clearing area.
  • Do not rule out important passage habitat because few birds are recorded during one survey.

Survey methodology: 4. Record and map findings

Keep records that can be used by the clearing supervisor, fauna spotter catcher and environmental representative. Map habitat and breeding evidence separately from incidental sightings.

  • Record date, start and finish time, weather, observers, survey method and area searched.
  • Record the number of birds, age class where known, behaviour, direction of movement and vegetation used.
  • Map nests, active breeding behaviour, repeated feeding locations, roost observations and potential passage corridors.
  • Photograph nests and habitat only where this can be done without approaching or disturbing the birds.
  • Record negative results, survey limitations and areas that could not be safely inspected.

Before habitat disturbance: 1. Confirm approvals and permits

Plan clearing to avoid dense vegetation wherever practicable and confirm the legal pathway before work starts. Spectacled Monarchs are listed as migratory under the EPBC Act, and Queensland applies additional protections to breeding places of special least concern animals.

Have the project ecologist check whether the action is likely to significantly affect the species or its important habitat. Refer the action under the EPBC Act if the significant impact test may be met.

EPBC status: Migratory species listed under the Bonn Convention

Queensland status: Special least concern animal where the relevant migratory conventions apply

  • Consider loss, substantial modification or isolation of dense habitat, effects on migration passage, breeding disruption and establishment of invasive species.
  • Check the current EPBC listing and referral requirements before construction or vegetation removal.
  • In Queensland, obtain or comply with a high risk Species Management Program where tampering with a breeding place of this special least concern animal is proposed or may occur.
  • Check state and territory wildlife legislation and obtain any required fauna, clearing, scientific or rehabilitation permits before works begin.
  • Include approval conditions, permit conditions and fauna procedures in the construction environmental management plan.

Before habitat disturbance: 2. Set out the work area

Have the clearing footprint surveyed and marked before machinery arrives. Retain connected dense vegetation, riparian strips and potential breeding habitat wherever possible.

  • Fence or flag the approved clearing boundary and no-go areas.
  • Keep machinery, spoil, storage, access tracks and lighting out of retained habitat.
  • Use a site-specific exclusion area around an active nest or breeding place, based on the behaviour of the birds, the nest location, the work type and advice from the fauna spotter catcher or ecologist.
  • Do not use a generic buffer where the risk assessment requires a larger area. Do not reduce an exclusion area without documented ecological and approval-based justification.
  • Plan staged clearing so that retained habitat remains connected and birds have safe escape routes.

Before habitat disturbance: 3. Complete pre-clearance checks

Carry out a final inspection close to the start of works, particularly where clearing occurs during the September to April breeding period or during autumn and spring passage.

Typical nest location: A vertical fork of a tree, sapling or shrub, or among hanging vines

Typical nest height: Approximately 1 to 6 m above ground

  • Inspect trees, saplings, shrubs, vertical forks, hanging vines and dense vegetation near watercourses.
  • Look for deep cup nests, adults carrying food, repeated visits, alarm calls, fledglings and dependent young.
  • Use binoculars where possible and avoid touching or shaking vegetation during the search.
  • Have the fauna spotter catcher and project ecologist decide whether a suspected nest is active before clearing continues.
  • Mark any active breeding place and record the decision, evidence and required controls.

Before habitat disturbance: 4. Induct the crew

Brief every person involved in clearing, supervision, driving and construction before work starts. The briefing should use photographs or clear descriptions and explain who can stop work.

  • Explain the species identification features and its use of dense vegetation.
  • Tell workers not to handle birds, nests or eggs unless authorised under the project approvals and fauna procedures.
  • Nominate the fauna spotter catcher as the person with authority to stop work for fauna risk.
  • Explain the exclusion zones, staged clearing sequence, escape routes and incident reporting process.
  • Provide contact details for the fauna spotter catcher, project ecologist, site supervisor and wildlife carer or veterinarian.

During habitat disturbance: 1. Clear progressively

Use slow, supervised clearing and give birds time to move away from machinery. The fauna spotter catcher must be able to stop work immediately when a bird, nest, dependent young or other fauna hazard is found.

Clear from the least disturbed edge towards retained habitat, using small stages that allow mobile birds to leave safely. Retain nearby vegetation until the active work area has been checked.

  • Remove understorey before larger trees only where the approved method allows it and the fauna spotter catcher considers it safe.
  • Pause between clearing stages to check foliage, forks, vines and ground beneath the work area.
  • Avoid felling trees towards retained habitat, watercourses or known escape routes.
  • Stop work if birds become trapped, repeatedly return to a nest or show signs of injury or distress.
  • Do not allow machinery operators to work ahead of the fauna spotter catcher.

During habitat disturbance: 2. Manage nests and breeding places

Treat any nest with eggs, nestlings, dependent fledglings or repeated adult attendance as an active breeding place until assessed by an authorised person. Do not move the nest or continue clearing around it without approval.

  • Stop work and establish a temporary exclusion area around the breeding place.
  • Keep workers, machinery, vehicles and unnecessary observers outside the exclusion area.
  • Contact the project ecologist and confirm the action required under the EPBC approval, Queensland Species Management Program or relevant state approval.
  • Do not remove, relocate or destroy a nest, egg or dependent young unless the authorised procedure expressly allows it.
  • Resume work only after the fauna spotter catcher and environmental representative record the decision and confirm that controls are in place.

During habitat disturbance: 3. Handle fauna lawfully

Only an authorised fauna spotter catcher or other appropriately permitted person may capture or handle a Spectacled Monarch. Most healthy birds should be allowed to leave without intervention.

  • Keep people and machinery still while a bird moves through the work area.
  • If capture is necessary, use the approved equipment and minimise handling time, noise and exposure.
  • Place an injured or distressed bird in a secure, ventilated container suitable for short-term transport.
  • Do not provide food or water unless directed by a wildlife carer or veterinarian.
  • Contact the nominated wildlife carer or veterinarian promptly and follow permit and animal welfare requirements.

During habitat disturbance: 4. Record incidents and stop-work events

Record every fauna interaction, including events that do not result in injury. Good records support compliance, improve future clearing and help identify recurring risks.

  • Record the date, time, location, species, number of birds, behaviour, habitat, work activity and outcome.
  • Record nests, eggs, young, injured birds, mortalities, relocations and animals that escaped unaided.
  • Take photographs only where this does not increase disturbance.
  • Document who stopped work, who assessed the event, what approval or procedure was applied and when work restarted.
  • Notify the site supervisor and environmental representative before the end of the shift, or immediately where an approval breach or serious injury has occurred.

After habitat disturbance: 1. Complete post-clearance checks

Finish each clearing area with a fauna check and a documented handover. Follow up any nest, injured bird, relocation or unexpected habitat loss rather than treating the incident as closed when machinery leaves.

Inspect the cleared area, retained vegetation and access routes after machinery has left. Check for injured birds, dependent young, damaged nests and fauna trapped in pits, drains or other structures.

  • Search beneath felled vegetation and around tree bases where safe to do so.
  • Check retained vegetation for birds that may have moved into cover during clearing.
  • Inspect open trenches, pipes, culverts and other hazards before they are covered or made inaccessible.
  • Remove or cover fauna hazards in accordance with the project environmental plan.
  • Record the date, area checked, personnel and result of the inspection.

After habitat disturbance: 2. Follow up relocated or injured birds

Monitor any bird that has been captured, treated or moved under an approved procedure. Use the release location and follow-up requirements set by the fauna spotter catcher, wildlife carer or permit.

  • Record the bird's condition before release, treatment details, release date and release location.
  • Release a healthy bird only when the authorised person considers conditions suitable and the location provides dense cover and access to food.
  • Keep a treated or injured bird with the wildlife carer or veterinarian until a lawful release decision is made.
  • Report deaths, failed releases and repeat injuries to the project ecologist and relevant authority where required.
  • Do not move birds to another site as a routine mitigation measure.

After habitat disturbance: 3. Monitor retained habitat

Inspect retained habitat after clearing where the project may have altered access, noise, lighting, drainage or edge conditions. Give extra attention to riparian vegetation, rainforest remnants and mangroves.

  • Check for new weed invasion, erosion, sediment movement, altered water flow and loss of canopy or understorey cover.
  • Look for continued use by Spectacled Monarchs during breeding and migration periods where monitoring is required by an approval or management plan.
  • Compare post-work observations with the pre-clearance habitat map and bird records.
  • Document whether exclusion areas remain intact and whether retained habitat is still connected.
  • Escalate unexpected habitat damage or repeated bird disturbance for ecological review.

After habitat disturbance: 4. Review the incident and close out records

Hold a short environmental review after clearing, and a formal review after any injury, mortality or active breeding place incident. Use the findings to improve the next work area.

  • Check that all approval conditions, permit conditions and fauna procedures were followed.
  • Identify whether timing, machinery, lighting, noise, supervision or vegetation handling contributed to the incident.
  • Update the clearing sequence, induction and risk assessment where controls were ineffective.
  • Submit required reports to the approval holder, regulator, land manager or wildlife authority within the required timeframe.
  • Keep survey, clearing, incident, rehabilitation and monitoring records together for the project file.

Rehabilitation actions: 1. Restore suitable vegetation

Rehabilitation should restore dense, connected vegetation rather than create isolated ornamental plantings. Focus on rainforest, moist forest, wet sclerophyll, riparian and mangrove characteristics that provide cover, feeding habitat and potential breeding sites.

Use locally appropriate native species and recreate layered vegetation. Prioritise structure and connectivity over a small number of mature trees.

  • Replant native canopy, mid-storey and understorey species suited to the local vegetation community.
  • Restore dense foliage along watercourses, gullies, forest edges and links to retained habitat.
  • Use natural regeneration where it is reliable, while protecting regenerating plants from grazing, machinery and trampling.
  • Avoid planting species that are invasive, unsuitable for the local community or likely to obstruct approved fire or access requirements.
  • Protect rehabilitation areas until plants are established and the intended vegetation structure is developing.

Rehabilitation actions: 2. Manage weeds, water and soil

Maintain the conditions that support insect prey and dense vegetation. Poor drainage, sediment movement, weeds and excessive disturbance can reduce habitat value even where trees remain.

  • Control invasive plants before they dominate the understorey or suppress native regeneration.
  • Prevent sediment, fuel, chemicals and rubbish from entering rainforest, riparian areas, wetlands or mangroves.
  • Maintain natural drainage and avoid sudden changes to water flow across rehabilitation areas.
  • Stabilise exposed soil and manage erosion promptly.
  • Inspect rehabilitation after heavy rain, construction changes and maintenance activities.

Rehabilitation actions: 3. Consider breeding features carefully

Spectacled Monarchs build small cup nests in forks or vines, so habitat restoration is usually more appropriate than installing nest boxes. Artificial features should only be used where a qualified ecologist considers them suitable for the local habitat and project approvals.

Nest form: Deep cup nest made from fine bark, plant fibres, moss and spider web

Typical nest setting: Tree fork, sapling, shrub or hanging vine, often near water

  • Prioritise mature shrubs, saplings, small trees, vines and dense foliage near suitable water-associated vegetation.
  • Do not install bat boxes, tree hollows or cave structures as a substitute for Spectacled Monarch nesting habitat.
  • Use nest boxes or artificial nest sites only where there is clear species-specific justification, an approved design and a maintenance plan.
  • Do not install structures that create hazards, attract pest animals or increase disturbance.
  • Remove temporary artificial structures when monitoring shows that they are unsuitable or no longer required.

Rehabilitation actions: 4. Manage lighting and disturbance

Limit night lighting and unnecessary noise around retained and rehabilitated habitat. Dense vegetation can be affected by edge disturbance even when the planted area itself is small.

  • Direct lights away from rainforest, riparian vegetation, mangroves and forest edges.
  • Use the lowest practical light intensity and avoid lighting retained habitat throughout the night.
  • Keep access tracks, maintenance areas and noisy equipment away from rehabilitation zones where practicable.
  • Retain quiet movement corridors between larger habitat patches.
  • Schedule high disturbance maintenance outside periods of active breeding where practicable and consistent with project approvals.

Rehabilitation actions: 5. Monitor habitat recovery

Monitor whether rehabilitation is becoming suitable for foraging, shelter and possible breeding use. A monitoring plan should match the scale and risk of the project.

  • Inspect plant survival, canopy development, understorey density, weed cover, water conditions and habitat connectivity.
  • Use repeat bird observations during spring and summer breeding surveys and during autumn and spring passage periods where required.
  • Record Spectacled Monarch detections, behaviour and habitat use without approaching nests or disturbing birds.
  • Repair failed plantings, erosion, weed outbreaks, lighting problems and damaged exclusion fencing.
  • Continue monitoring until the agreed rehabilitation performance criteria have been met and the area is no longer exposed to routine construction risks.
