Black-winged Monarch (Monarcha frater)

The Black-winged Monarch is a small insectivorous rainforest bird that breeds in tropical north-eastern Australia and moves to New Guinea outside the breeding season. It can be affected by clearing, fragmentation, disturbance and changes to rainforest-associated habitat on works sites. It is least concern, but is listed as a migratory species under the EPBC Act through the Bonn Convention, so actions likely to significantly affect it may require referral.

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 Black-winged Monarch is a summer breeding migrant in tropical north-eastern Australia, mainly in Far North Queensland. Australian breeding records and observations indicate presence from November to March, but exact arrival and passage dates can vary and remain poorly known.

Breeding mode: Seasonal nesting in Australia. Further breeding-system details are not recorded.

Breeding period: November to March in tropical Far North Queensland.

Nest: Goblet shaped. Nest placement and breeding-site structure are not recorded.

Clutch size: Believed to be 2 to 3 eggs.

Incubation: Not recorded.

Fledging and dependent young: Not recorded.

Age at maturity and breeding frequency: Not recorded.

Timing may vary between years and locations, and the species' exact arrival, passage and non-breeding movements are still poorly known.

  • Arrival in Australia for breeding, southward movement: Arrival dates are not firmly established, but the species is present in tropical north-eastern Australia for breeding from November.
  • Breeding in Australia, tropical Far North Queensland: Breeding records and seasonal accounts place breeding in Australia from November to March, with nests recorded in November, December and January.
  • Non-breeding presence in Australia, occasional adults: Most Australian birds are thought to move to New Guinea after breeding, although a small number of adults may remain in Australia over winter.
  • Departure from Australia to New Guinea, northward movement: The Australian breeding population leaves its Far North Queensland range in March, although the exact route and destination in New Guinea remain uncertain.
  • Highest clearing risk: Clearing or construction in rainforest and adjacent mixed tropical woodland is most likely to harm nests, eggs or dependent young from November to March.

Identification: Appearance

The Black-winged Monarch is a small forest bird with a distinctive black face, grey upperparts and breast, and a rufous belly. Field identification can be difficult, especially for young birds and during migration.

Adults have much black on the face. The breast and upperparts are grey, while the belly is rufous. The flight feathers are black, rather than blue-grey edged.

The Australian-breeding form is the Pearly monarch, Monarcha frater canescens. Plumage variation within this group is still being investigated.

Body size: Small bird. A supported measurement is not available.

Colour pattern: Black face, grey breast and upperparts, rufous belly, and black remiges

Identification: Calls and similar species

No reliable call description is available for site identification. The species is an insectivorous songbird, so call recordings and photographs should be retained where identification is uncertain.

The main identification issue is separation from the Black-faced Monarch. Island Monarchs can also share the grey and rufous colour pattern. Juvenile and immature Black-winged Monarchs are poorly described.

  • Check the head pattern carefully.
  • Check whether the flight feathers are black or blue-grey edged.
  • Use clear photographs, recordings and an experienced bird identifier for uncertain records.

Identification: Field signs

Direct sightings and calls are the most useful field evidence. A goblet-shaped nest may be encountered during the breeding period.

Droppings, whitewash, stains, odour, roost marks and other distinctive signs are not known to be reliable indicators for this species.

  • Record the location, habitat, date and behaviour of every sighting.
  • Photograph the bird from several angles where this can be done without disturbance.
  • Do not approach or handle a nest unless authorised and necessary.

Distribution: Australian range

In Australia, the Black-winged Monarch is associated with tropical north-eastern forests. The species is mapped in Queensland and New South Wales, although the detailed Australian records in this profile are concentrated in Queensland.

The main Australian range is in Queensland, including Cape York Peninsula, the north and east of the peninsula, the eastern coast of northern Cape York Peninsula, and areas south to Cooktown.

The species occurs on Torres Strait Islands during migration. It is also mapped in New South Wales, but specific New South Wales localities are not detailed here.

  • Far North Queensland tropical forests
  • Cape York Peninsula, especially the north and east
  • Eastern coast of northern Cape York Peninsula
  • Torres Strait Islands during migration

Distribution: Range outside Australia

The Black-winged Monarch also occurs in New Guinea. Some New Guinea subspecies are considered sedentary, while the Australian-breeding form is believed to move there after breeding.

The exact non-breeding location of the Australian-breeding form remains uncertain. Records include northern, central, south-eastern and north-western parts of New Guinea for the broader species group.

Distribution: What to check on a site

Prioritise rainforest remnants, wet tropical forest and mixed tropical woodland close to rainforest. A site can be relevant even where the bird is recorded only during passage.

  • Map connected rainforest and woodland patches.
  • Check nearby forest across the wider clearing footprint, not only the immediate work area.
  • Record whether habitat provides a link between coastal Australia, Cape York Peninsula and Torres Strait movement areas.

Habitat: Vegetation to look for

Rainforest is the primary habitat. The Black-winged Monarch also uses mixed tropical open eucalypt forest and woodland next to rainforest where the understorey has rainforest-like elements.

Look for tropical rainforest, wet forest and rainforest edge vegetation. Adjacent open eucalypt woodland can also be suitable where the understorey is dense or structurally similar to rainforest.

Habitat quality is likely to be higher where the canopy and understorey remain connected and there is little isolation from other forest.

  • Rainforest remnants
  • Tropical wet forest
  • Mixed tropical open eucalypt forest beside rainforest
  • Woodland with a rainforest-like understorey

Habitat: Landform and site features

The species is associated with forested parts of tropical north-eastern Australia. Retain natural vegetation links, forest edges and sheltered understorey within and beside the work area.

No specific elevation, waterbody, hollow or rock feature is required for this profile.

  • Continuous or partly connected forest
  • Rainforest edges and adjoining woodland
  • Dense understorey within retained vegetation
  • Vegetated links between larger forest patches

Habitat: Site assessment

Inspect the whole clearing envelope and nearby habitat before works begin. A low number of observations does not by itself show that habitat is unimportant, particularly during migration passage.

  • Search early in the planning process.
  • Include retained vegetation, access tracks, compounds and temporary work areas.
  • Document habitat condition, connectivity and the presence of invasive plants.

Foraging habitat: Foraging vegetation

The Black-winged Monarch feeds on insects and usually gleans them from foliage. It may sally for prey, but this behaviour is not common.

Search rainforest foliage, rainforest edges and the understorey of adjacent tropical woodland. Retained vegetation with a rainforest-like structure may provide feeding habitat even where the site is not closed rainforest.

  • Leafy rainforest canopy and understorey
  • Dense vegetation along rainforest edges
  • Rainforest-like understorey in adjoining woodland
  • Connected vegetation around proposed clearing areas

Foraging habitat: Foraging behaviour

Watch for a small bird moving through foliage and taking insects from leaves and twigs. Occasional short flights to intercept prey may occur, but most feeding is by foliage gleaning.

  • Record the vegetation layer being used.
  • Record whether the bird is feeding, moving through or defending an area.
  • Avoid excessive repeated visits to active feeding areas.

Foraging habitat: Works-site considerations

Clearing and canopy reduction can remove feeding foliage and break up movement routes. Dust, lighting, noise and changes to vegetation structure should be managed where work occurs beside rainforest.

  • Retain rainforest edges and understorey where practicable.
  • Stage clearing to reduce the area affected at one time.
  • Prevent unnecessary lighting into retained forest.

Breeding habitat: Breeding places

The Australian-breeding form breeds in tropical forests of Far North Queensland from November to March. Nest records include November, December and January, and the nest is goblet shaped.

Look for goblet-shaped nests in tropical forest during the breeding period. Detailed nest placement information is limited, so all suspected nests should be treated cautiously.

The species is not known from this profile to form breeding colonies. Do not assume that an empty-looking patch is unused without an appropriate inspection.

Breeding period in Australia: November to March

Recorded nest months: November, December and January

Nest form: Goblet shaped

Clutch: Believed to be 2 to 3 eggs

  • Search retained rainforest and dense rainforest-like understorey.
  • Inspect vegetation within the proposed clearing footprint and along access routes.
  • Treat any suspected nest as an active breeding place until checked by a suitably qualified person.

Breeding habitat: Breeding-season work planning

Avoid clearing or high-disturbance work near suspected nests during the Australian breeding period where practicable. Arrange a targeted inspection before vegetation removal, particularly in Far North Queensland rainforest.

If a nest is found, stop work close enough to cause disturbance and obtain advice from the project ecologist and relevant regulator.

  • Use a qualified fauna spotter catcher for pre-clearing checks.
  • Mark the location discreetly and keep workers away from the nest.
  • Recheck the area if clearing is delayed or conditions change.
  • Follow any permit, approval or species management plan conditions.

Breeding habitat: Queensland regulatory point

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

  • Confirm Queensland species management requirements before works.
  • Escalate any nest, dependent young or repeated breeding activity to the project ecologist.
  • Consider EPBC Act referral requirements where the action may significantly affect the species.

Sheltering habitat: Shelter to retain

Specific roosting and shelter structures have not been established for the Black-winged Monarch. For field work, treat intact rainforest, dense understorey and connected forest as the main sheltering habitat.

Retain leafy vegetation, rainforest edges and dense understorey. These features provide cover for a small insectivorous bird moving through the forest and may also support resting between feeding movements.

  • Intact rainforest canopy and understorey
  • Dense vegetation beside clearings
  • Connected forest strips
  • Rainforest-like understorey in adjacent woodland

Sheltering habitat: Roosts and resting sites

No particular roost tree, hollow, cave, burrow or communal roost is identified for this species. Avoid removing potentially useful cover at night or during periods of heavy movement unless the work area has been assessed.

  • Do not assume that lack of a visible nest means lack of use.
  • Check retained vegetation before night works and major clearing.
  • Direct temporary lighting away from forest edges and retained habitat.

Sheltering habitat: Handling and exclusion

The species is a wild migratory bird, not an animal to be relocated routinely. If an individual is injured or trapped, use an authorised wildlife carer or fauna specialist and follow approval conditions.

  • Do not chase birds into retained vegetation.
  • Use gradual, supervised clearing where fauna risks are present.
  • Record any injured, dead or displaced birds and report them through the project process.

Migration and seasonal presence: Seasonal presence

The Australian-breeding form arrives in tropical north-eastern Australia during the wet season and breeds from November to March. It leaves the Far North Queensland breeding range in March and is believed to spend the non-breeding season in New Guinea.

The known Australian breeding period is November to March. Birds disappear from the Far North Queensland breeding range when cooler conditions arrive.

Some adults may remain in Australia over winter, so absence outside the main breeding period should not be assumed. Australian birds are thought to make short-distance movements into southern New Guinea after breeding.

  • Arrival and breeding presence: wet season, with breeding from November to March
  • Departure from the Far North Queensland breeding range: March
  • Non-breeding season: believed to be in New Guinea, at an uncertain location
  • Possible exception: a small number of adults may overwinter in Australia

Migration and seasonal presence: Passage periods

For migratory flycatchers generally, southward movement occurs in austral autumn and northward movement occurs in austral spring. Birds north of known breeding areas can be mobile during both seasons.

The exact Black-winged Monarch passage schedule is not settled. Allow for passage use outside the November to March breeding period, especially in northern Queensland, Cape York Peninsula and Torres Strait.

  • Consider autumn and spring passage when planning surveys.
  • Use repeated observations where a project may affect forest links or coastal movement areas.
  • Record birds moving through as well as birds holding territories or feeding.

Migration and seasonal presence: Important habitat in Australia

Important habitat includes rainforest and mixed tropical woodland adjacent to rainforest where the understorey has rainforest-like elements. Habitat suitable for migration passage should be considered even when few birds are recorded during a survey.

  • Rainforest used for breeding or feeding
  • Adjacent mixed tropical woodland with suitable understorey
  • Connected forest and coastal vegetation links
  • Specific locations suitable for migration passage, including Cape York Peninsula, parts of the Wet Tropics and Torres Strait

Migration and seasonal presence: Survey timing and decisions

Plan surveys for the likely season of use, and do not rely on a single visit to rule out habitat. If a project affects important habitat, assess breeding, feeding, resting and passage impacts together.

  • Check the regional breeding and migration context before clearing.
  • Repeat surveys when timing, weather or access may have reduced detection.
  • Seek EPBC Act advice if the action may have a significant impact on the listed migratory species.

Threats: Clearing and fragmentation

The main works-site risks are loss and fragmentation of rainforest-associated habitat, disturbance during breeding or passage, and changes to forest processes. The species has a limited Australian breeding range, so local losses can matter even where the bird is not recorded on every visit.

Removing rainforest, rainforest edge or suitable adjoining woodland can reduce feeding and breeding habitat. Breaking forest into isolated patches can also affect movement and passage through the landscape.

  • Avoid clearing intact rainforest where practicable.
  • Retain connected vegetation between larger forest patches.
  • Keep temporary work areas and access tracks within already disturbed areas where possible.

Threats: Fire, hydrology and vegetation change

Altered fire regimes, nutrient cycles and hydrological cycles can change rainforest-associated vegetation and its understorey. Invasive plants can also reduce the habitat structure used by insectivorous forest birds.

  • Prevent unnecessary fire encroachment into rainforest edges.
  • Manage drainage and runoff so retained forest is not dewatered or flooded.
  • Control invasive vines such as rubber vine, Cryptostegia grandiflora, where relevant.
  • Inspect for black rats and manage them under approved biosecurity and pest plans.

Threats: Breeding, feeding and passage disturbance

Noise, vibration, lighting, vegetation removal and repeated human activity can disrupt feeding, breeding, resting or migration behaviour. Take extra care from November to March and during autumn and spring passage periods.

  • Complete pre-clearing checks before vegetation removal.
  • Stop and reassess work if a nest, dependent young or repeated territorial activity is found.
  • Keep machinery, lighting and worker movement away from retained forest where practicable.

Threats: Collision and legal risk

Large structures, including buildings, power lines and wind turbines, can cause bird mortality during migration. A project may also require EPBC Act referral if it is likely to have a significant impact on the Black-winged Monarch or its important habitat.

  • Assess collision risk for tall structures and overhead lines near migration habitat.
  • Apply project approval conditions and species management requirements.
  • In Queensland, obtain the required high risk species management program before tampering with a breeding place.
  • Document sightings, habitat affected and mitigation actions.

Survey methodology: 1. Desktop assessment

Survey effort should focus on rainforest and mixed tropical woodland beside rainforest. The Black-winged Monarch is small, insectivorous and easily overlooked, so use experienced observers and repeat visits in suitable weather.

Map rainforest, tropical forest and adjacent mixed woodland before planning works.

Check records for the project area, nearby habitat links, wetlands and other likely movement areas.

Treat habitat in northern Queensland, Cape York Peninsula, the Wet Tropics and Torres Strait as a priority for review. Also check records in New South Wales where the species is mapped.

Identify whether works overlap the Australian breeding period, which is generally November to March in tropical north-eastern Queensland, or the broader migration periods in austral autumn and spring.

  • Review the latest state and Commonwealth species records.
  • Check whether the action may affect a listed migratory species under the EPBC Act.
  • Map all rainforest patches, adjacent woodland, forest edges and proposed clearing areas.
  • Record nearby habitat that could be used during migration, even if few birds are present during the survey.

Survey methodology: 2. Field detection

Search quietly through rainforest and adjacent mixed tropical woodland. Look and listen for small insectivorous birds moving through foliage.

Use observers who can distinguish the Black-winged Monarch from the Black-faced Monarch. Pay attention to the black face and black remiges, or flight feathers, of adult Black-winged Monarchs.

The species is poorly known in Australia. Use repeated searches rather than relying on one negative visit.

  • Survey in daylight when birds are active and visibility is suitable.
  • Avoid heavy rain, strong wind and other conditions that reduce bird activity or detection.
  • Search the canopy, mid-storey and dense foliage along edges, tracks and proposed clearing boundaries.
  • Use passive observation and listening first. Use call playback only where approved and where it will not increase disturbance.
  • Repeat surveys during the breeding season and during likely passage periods if the site contains suitable habitat.

Survey methodology: 3. Record and assess results

Treat a sighting, call detection, nest or repeated use of habitat as a trigger for ecological review. A lack of detection does not by itself demonstrate that habitat is unimportant.

Record enough detail to support the impact assessment and guide the clearing crew.

  • Record date, start and finish time, observers, weather and survey conditions.
  • Map each detection with a location, habitat type and behaviour.
  • Record whether the bird was feeding, moving through, defending a territory, carrying nesting material or attending a nest.
  • Photograph birds, nests and habitat where this can be done without disturbance.
  • Record the number of birds, age or plumage where known, and the direction of movement.
  • Document all areas searched, survey duration and any constraints on detection.

Before habitat disturbance: 1. Avoidance, approvals and permits

Avoid clearing suitable habitat wherever practicable, particularly rainforest, adjacent mixed woodland and places used for breeding or passage. Confirm Commonwealth and state requirements before work starts, and brief every person who may enter the clearing area.

Check whether the action is likely to have a significant impact on the Black-winged Monarch as a listed migratory species under the EPBC Act. Refer the action before it starts if a significant impact is likely.

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

Obtain any Queensland or New South Wales wildlife permits, approvals and species management documents required for the proposed work. Confirm requirements with the relevant state agency before disturbance.

  • Redesign the footprint to retain rainforest and adjacent mixed woodland where possible.
  • Retain connected habitat and avoid isolating small rainforest patches.
  • Keep construction compounds, access tracks, stockpiles and night lighting out of retained habitat.
  • Include migratory habitat and likely passage areas in the impact assessment, not just places where birds were recorded.
  • Keep copies of approvals, permits, the SMP and fauna management procedures at the site office.

Before habitat disturbance: 2. Pre-clearance survey and breeding checks

Complete a final fauna inspection shortly before clearing. Search all vegetation proposed for removal and the retained habitat beside the work area.

Breeding records include November, December and January, and the Australian breeding period is generally November to March. Schedule clearing outside this period where practicable, but continue to check for active breeding places because some adults may remain in Australia outside the main breeding period.

  • Search for adults carrying food or nesting material, repeated alarm behaviour and birds returning to one location.
  • Inspect dense foliage and suitable rainforest vegetation for the goblet-shaped nest reported for this species.
  • Mark any active nest or suspected breeding place and stop planning in that area until it has been assessed.
  • Check for birds using the site during northward spring migration and southward autumn migration.
  • Have the ecologist document the proposed exclusion area and the conditions for recommencing work.

Before habitat disturbance: 3. Site controls and crew induction

Set out no-go areas before machinery arrives. Use visible fencing and signs that can be understood by all crews and subcontractors.

The species has no established species-specific buffer distance in the available guidance. Set buffers using the nest location, vegetation structure, activity level, disturbance type and advice from the qualified ecologist or regulator.

  • Fence retained rainforest, adjacent mixed woodland and all approved exclusion areas.
  • Nominate a fauna spotter catcher with authority to stop work.
  • Induct all workers on the species, its migratory status, exclusion areas and stop-work procedure.
  • Tell workers not to chase, handle, feed or photograph birds at close range.
  • Plan lighting, noise, haul routes and work hours to reduce disturbance to retained habitat and likely movement areas.
  • Display the fauna spotter catcher contact details and the wildlife rescue contact pathway at the site office.

During habitat disturbance: 1. Sequential clearing and supervision

Clear in a controlled sequence from disturbed edges towards retained habitat, with the fauna spotter catcher directing each step. Stop work whenever a bird, nest or other potential breeding place cannot be safely managed under the approved controls.

Use staged clearing so birds have an opportunity to move into retained habitat. Do not surround or isolate a bird with machinery.

The fauna spotter catcher must inspect each work area before and during clearing and must have clear authority to stop machinery.

  • Clear the smallest practicable area at each stage.
  • Work from the outside of the clearing footprint towards retained vegetation.
  • Maintain exclusion fencing and check it after machinery movements.
  • Pause when a bird is flushed repeatedly, behaves defensively or returns to a particular tree or shrub.
  • Do not use machinery to push vegetation into retained habitat.
  • Keep a clear line of communication between the operator, spotter catcher and site supervisor.

During habitat disturbance: 2. Birds, nests and breeding places

Only authorised and appropriately trained people may handle wildlife. Avoid capture where the bird can move safely into suitable retained habitat.

If an active breeding place is found, stop work in the immediate area and apply the approved permit, SMP and ecological advice before proceeding.

  • Stop work and establish a temporary exclusion area around any suspected nest or breeding place.
  • Do not touch, move or destroy a nest unless this is expressly authorised.
  • Keep people, machinery and unnecessary noise away from the exclusion area.
  • Record the location, condition of the nest, adult behaviour and the action taken.
  • If a bird is trapped, injured or unable to leave safely, contact the fauna spotter catcher and an authorised wildlife carer or veterinarian.
  • Do not release a captured bird at an unsuitable location or without advice on the approved release site.

During habitat disturbance: 3. Incident records and escalation

Treat an unauthorised nest disturbance, injury, death or loss of an exclusion area as an environmental incident. Escalate it promptly through the project approval and fauna management chain.

Record incidents while details are fresh and preserve photographs, maps and approval documents.

  • Record the date, time, location, people involved, machinery and sequence of events.
  • Record the species identification, number of birds and observed injury or behaviour.
  • Notify the site supervisor, project ecologist and approval holder immediately.
  • Notify the relevant state or Commonwealth authority where required by the approval, permit or SMP.
  • Suspend related work until the ecologist confirms the control measures and approvals remain valid.
  • Update the site risk assessment and toolbox briefing after every incident.

After habitat disturbance: 1. Post-clearance checks

Complete a final inspection before the area is handed back to construction or rehabilitation crews. Review whether birds moved into retained habitat, whether exclusion areas remained effective and whether any approval conditions were met.

Inspect the cleared footprint and its edges after each clearing stage. Look for injured birds, trapped fauna, damaged nests and unexpected habitat impacts.

Check retained rainforest and adjacent woodland for signs of repeated bird activity or disturbance.

  • Walk the full clearing boundary and all machinery access routes.
  • Check under vegetation piles, beside fences and around temporary structures before they are removed.
  • Confirm that no nest, breeding place or animal remains within the work area.
  • Remove hazards such as unsecured netting, open pipes and entangling materials.
  • Keep exclusion fencing in place until the ecologist confirms that it can be removed.

After habitat disturbance: 2. Reporting and monitoring

Report survey results, clearing outcomes and incidents in the project environmental record. Monitoring should match the risk of the action and focus on retained habitat and any known breeding or movement areas.

Where a bird has been relocated or released, document its condition and the release outcome.

  • Provide mapped records of detections, nests, exclusion areas and cleared habitat.
  • Record the final area of rainforest, adjacent woodland and connected habitat retained.
  • Document all fauna handled, including the person who handled it, destination, release location and condition.
  • Complete follow-up observations where the approval, SMP or ecological risk assessment requires them.
  • Report any unexpected decline in retained habitat condition, repeated disturbance or mortality.

After habitat disturbance: 3. Incident review and corrective action

Hold a short review after clearing and after any fauna incident. Use the findings to improve the next work stage rather than repeating the same risk.

Keep the review practical and assign each corrective action to a named person.

  • Compare actual clearing with the approved footprint.
  • Check whether the stop-work process worked and whether the spotter catcher could reach machinery operators quickly.
  • Review timing against the November to March breeding period and autumn and spring migration periods.
  • Repair or extend exclusion fencing where birds or workers entered no-go areas.
  • Update the induction, clearing sequence and fauna rescue contacts before the next stage.

Rehabilitation actions: 1. Restore suitable habitat

Rehabilitation should restore rainforest structure and reconnect retained habitat. Focus on native vegetation, dense foliage and low-disturbance movement routes rather than installing artificial structures that have not been shown to suit this species.

Replant cleared edges with locally appropriate native rainforest species and understorey plants. Restore mixed tropical woodland beside rainforest where that habitat was removed.

Aim for a connected vegetation structure that supports insect prey, shelter and movement.

  • Use local provenance plants where practical and appropriate.
  • Restore multiple vegetation layers, including understorey and foliage cover.
  • Reconnect isolated rainforest patches and retain natural edge vegetation.
  • Protect revegetation from fire, grazing, vehicle damage and compaction.
  • Keep machinery and storage areas outside rehabilitation zones.

Rehabilitation actions: 2. Weeds, water and site conditions

Control invasive plants that degrade rainforest edges, riparian habitat and understorey. Rubber vine is an example of an invasive vine identified as harmful in northern Queensland.

Manage rehabilitation so it supports natural insect availability and avoids creating new hazards for birds.

  • Remove weeds using methods that do not damage retained native vegetation.
  • Prevent weed spread on machinery, vehicles and soil stockpiles.
  • Maintain natural drainage and avoid altering hydrological cycles in retained habitat.
  • Avoid unnecessary broad-spectrum insecticide use in restored habitat.
  • Use low-spill lighting and direct lights away from rainforest and woodland edges.
  • Inspect rehabilitation after storms, fire, flooding and major construction activity.

Rehabilitation actions: 3. Artificial structures and long-term monitoring

The Black-winged Monarch has no established requirement for nest boxes, bat boxes, artificial nest sites or roost structures. Do not install these structures as a default measure.

The species uses a goblet-shaped nest, but suitable artificial nest designs and occupancy methods have not been established. Seek advice from a qualified ornithologist before proposing any artificial breeding structure.

  • Prioritise natural habitat restoration over nest boxes or artificial roosts.
  • Install an artificial structure only where it has a documented ecological purpose, suitable design and approval.
  • Do not install bat boxes as a substitute for monarch habitat.
  • Monitor plant survival, weed cover, habitat connectivity and bird use of restored areas.
  • Repeat bird surveys during the breeding period and migration periods where the project risk warrants it.
  • Review monitoring results and adapt weed control, lighting, access and rehabilitation methods over the life of the project.
