Papuan Eclectus (Eclectus polychloros)

Conservation status

Queensland, Nature Conservation Act 1992: Endangered.

Breeding season

The following pattern is based on the reported April to September breeding period. Timing can vary across the species range, and the supplied documents do not provide detailed dates for incubation, fledging or dispersal.

Months are January to December. The documents provide a breeding period of April to September but do not provide detailed incubation, fledging or dispersal timing.

• Breeding, mating and laying: Breeding is reported from April to September. Females use high tree hollows and may mate with multiple males.
• Young in nest or dependent: Two eggs are typically laid and often only one young fledges. The supplied documents do not give incubation or fledging dates, so dependent young may overlap the reported breeding period and extend beyond September.
• Movement to food trees: Males travel between nest hollows and food trees throughout the year and may use a foraging range of more than 30 km².
• Nest hollow occupancy: Females may remain in a suitable hollow for up to 11 months each year and may return to the same hollow over several years.
• Highest clearing risk: April to September is the highest risk period because breeding and young in hollows are reported during these months. Clearing can also harm resident females and nesting habitat outside this period because hollows may be occupied for much of the year.

Identification

The Papuan Eclectus is a conspicuous, short tailed parrot with a large head and strong sexual colour differences. It is most readily detected by its loud calls and by birds flying above the forest canopy.

Males are mainly bright emerald green, with red underwings, blue primary feathers and an orange to yellow bill. Females are mainly bright red, with a violet or blue belly and a dark to black bill.

Adults are about 35 to 42 cm long. The body is stocky, the head is large and the tail is relatively short.

Identification: Sexes and similar birds

The extreme difference between the green male and red female is the main field distinction. The species was formerly grouped with other Eclectus forms, so older records and databases may use Eclectus roratus or Eclectus Parrot.

The Australian form, Eclectus polychloros macgillivrayi, is described as larger than the Papuan form. Other regional Eclectus forms can differ in the shade of green, the amount of yellow on the tail and the colour of the bill.

Identification: Field signs

Calls include a loud, high pitched squawk, a lower rasping caw, whistles and screeches. Birds are often seen flying above forest at first light.

The main breeding sign is a large tree hollow high in a mature tree. Females may remain at a suitable hollow for up to 11 months each year and may return to the same hollow over several years.

Tracks, scats, sloughed skin and eyeshine are not useful identification signs for this bird and are not described in the supplied documents.

• During pre-clearing inspections, check the upper canopy and large trees for green males, red females and birds entering or leaving hollows.
• Record loud squawks and repeated flights over rainforest, particularly around first light.
• Treat a suitable high hollow as potential breeding habitat until inspections establish that it is not being used.

Distribution: Australian range

In Australia, the Papuan Eclectus is restricted to the north of Queensland. The supplied documents do not provide a mapped Australian population estimate, population trend or formal bioregion list.

The Australian form occurs on the tip of Cape York Peninsula and in north-east Queensland. It is associated with rainforest patches in the Iron Range and McIlwraith Range.

The supplied documents do not identify additional Australian states or provide a complete list of Queensland bioregions. Records outside Cape York should therefore be checked against current taxonomic and distribution databases.

Australian state: Queensland only in the supplied documents

Known Australian strongholds: Rainforest patches in the Iron Range and McIlwraith Range on Cape York Peninsula

Population size: Not stated

Population trend: Not stated

Distribution: Wider range and subpopulations

The species occurs across New Guinea and nearby islands, including the Bismarck Archipelago and Solomon Islands, as well as north-east Australia. The recognised forms include the Papuan, Solomon Island and Australian forms.

The species has also been reported as introduced to the Solomon Islands. This does not describe the Australian distribution and should not be used to infer Australian occupancy.

Habitat: Forest type and structure

Papuan Eclectus uses tropical rainforest, particularly lowland and foothill forest. In Australia, available information points to isolated rainforest patches on Cape York Peninsula.

The species is endemic to rainforest habitats from New Guinea to the Solomon Islands and the tip of Cape York Peninsula. It usually remains in the rainforest canopy.

Key habitat features are mature forest, a continuous or connected canopy, fruiting and flowering trees, and large trees containing high nest hollows.

• Retain mature canopy trees and large hollow bearing trees within and beside the clearing area.
• Inspect rainforest patches, riparian rainforest and connected canopy before vegetation removal.
• Map canopy breaks and isolated rainforest patches because the Australian distribution is concentrated in these habitats.

Habitat: Height and climate limits

The supplied documents describe lowland and foothill forest but do not give an elevation limit. They report nesting at 20 to 30 m above ground and note that lower hollows can flood in the rainforest climate.

No numerical temperature, rainfall or elevation thresholds are provided.

Foraging habitat: Food resources

Papuan Eclectus feeds mainly in the rainforest canopy and relies heavily on fruit resources. Males commonly supply food to females and chicks during nesting.

The diet consists mainly of fruit and fruit pulp. Seeds, leaf buds, blossoms, nectar, figs and nuts are also eaten.

Documented food plants include Salacia chinensis, also called lolly berry, Leea indica, also called bandicoot berry, and the seeds of Dodonaea lanceolata.

• Retain fruiting and flowering rainforest trees where practicable.
• Schedule vegetation inspections around food trees as well as around nest hollows, because feeding birds may be away from nesting trees.
• Record fruiting trees and canopy feeding activity during fauna surveys.

Foraging habitat: Foraging movements

Males travel long distances to obtain food for females and chicks. The supplied account reports a foraging range of more than 30 km².

Males generally feed females in the morning and afternoon and may travel between the nest hollow and distant food trees.

Reported male foraging range: More than 30 km²

• Assess retained vegetation beyond the immediate clearing footprint where it may be connected to a nest hollow.
• Avoid assuming that a bird seen in one forest patch nests in that same patch.

Breeding habitat: Breeding biology

Breeding depends on scarce, elevated tree hollows in mature rainforest. Females defend and occupy suitable hollows for long periods, while males provide most food to the female and young.

Females lay two eggs per clutch, although often only one young fledges. Females incubate the eggs while males forage and deliver food.

The species can show cooperative polyandry. Multiple males may mate with one female and assist with feeding the female and chicks.

The supplied documents do not provide a reliable incubation period, age at maturity or wild lifespan. Reported lifespans of about 20 to more than 60 years refer to Eclectus parrots generally and are largely based on captive birds.

Breeding season: April to September

Clutch size: Typically two eggs

Fledging outcome: Often only one young fledges

Incubation period: Not stated

Age at maturity: Not stated

Lifespan: About 20 to more than 60 years reported for Eclectus parrots, mainly from captivity; a wild lifespan for Papuan Eclectus is not stated

Breeding habitat: Breeding habitat requirements

Nests are in hollow cavities in mature trees, usually 20 to 30 m above ground. Good hollows are scarce, and females may defend one against other females, sometimes lethally.

Lower hollows are generally avoided because they can flood in the rainforest climate. A female may stay at a suitable hollow for up to 11 months each year and may use it over multiple years.

Typical nest height: 20 to 30 m above ground

Female occupancy: Up to 11 months each year

• Retain mature trees with large hollows, including trees that appear partly dead but remain standing.
• Inspect trees at approximately 20 to 30 m height where safe access or suitable observation methods are available.
• Use a suitably qualified fauna spotter catcher and arborist for hollow inspections before felling or limb removal.
• Prevent machinery access and prolonged noise or activity around a confirmed active hollow during breeding and dependent young periods.

Sheltering habitat: Tree hollows

The principal shelter and breeding refuge is a high tree hollow in mature rainforest. The supplied documents do not describe separate night roosts or a required hollow entrance size.

Females remain in suitable nest hollows for long periods and may return to the same hollow in successive years. The hollow also provides shelter for eggs and young.

Hollows are generally 20 to 30 m above ground. Lower cavities may flood and are generally avoided.

Known refuge type: High tree hollows in mature rainforest

Known refuge height: Usually 20 to 30 m above ground

Hollow entrance size: Not stated

• Retain hollow bearing trees within the impact area and along retained forest edges.
• Protect the tree, its root zone and the surrounding canopy where a hollow is confirmed or considered suitable.
• Do not rely on the absence of a visible adult as evidence that a hollow is unused.

Sheltering habitat: Other shelter features

No species specific information is supplied on ground cover, burrows, rock shelters, night roosts or separate non breeding refuges. Field assessment should therefore focus first on mature canopy trees and high hollows.

Threats: Clearing and fragmentation

The supplied documents identify scarce nesting hollows, flooding of low hollows and habitat restriction as important ecological sensitivities. Clearing that removes mature rainforest or breaks links between nest hollows and food trees presents a direct project risk.

Removal of lowland or foothill rainforest can remove food trees, canopy cover and high nest hollows. Fragmentation can separate a nesting female from the food resources used by males to feed her and the chicks.

Because females may occupy a suitable hollow for up to 11 months and may reuse it over several years, a tree can remain important outside the months when eggs or young are visible.

• Locate and retain mature hollow bearing trees before clearing design is finalised.
• Map connected rainforest and food trees around known or suspected nest hollows.
• Avoid creating unnecessary canopy gaps around retained rainforest patches.

Threats: Construction disturbance and roads

The supplied documents do not quantify responses to construction noise, vibration, artificial light or roads. These pressures should nevertheless be assessed where works occur near a nest hollow or narrow rainforest patch.

Males may travel more than 7.2 km to mate with females and more than 30 km² while obtaining food, so project effects may extend beyond the visible clearing edge.

• Use staged clearing and pre-clearing checks around potential nest trees.
• Control lighting, noise and repeated vehicle movements near confirmed nest hollows.
• Assess collision and access risks where new roads cross regular canopy flight paths.

Threats: Fire, predators and other pressures

The supplied documents do not provide a species specific assessment of fire, introduced predators, disease or hydrology change. They do note that peregrine falcons are predators and that lower hollows can flood in the rainforest climate.

Changes to drainage or ground levels may increase flooding risk for lower cavities. Fire can also affect rainforest structure and hollow bearing trees, but a fire response or threshold is not specified in the documents.

• Avoid altering drainage around retained rainforest and hollow bearing trees.
• Include hollow bearing trees and rainforest edges in fire planning and post fire inspections.
• Record signs of predation, sick birds or unusual mortality and refer them to the relevant Queensland wildlife authority.

Survey methodology: 1. Diurnal habitat and hollow inspection

Survey effort should focus on lowland and foothill rainforest, rainforest patches and mature trees with hollows. Papuan Eclectus is canopy dwelling, often detected by loud calls or flight above forest, and may use nest hollows 20 to 30 metres above ground. [Sources support this section:

Map rainforest, rainforest edges, mature canopy trees and all trees with visible hollows before clearing.

Inspect retained and proposed clearing areas during daylight for feeding birds, flight paths, roosting activity, nest entrances, feathers and other signs.

Give particular attention to hollows approximately 20 to 30 metres above ground, because the species commonly nests at this height.

Use binoculars or a telescope to inspect high hollows from the ground, and do not climb trees unless the work is separately authorised and safe.

Recorded nesting height: 20 to 30 metres above ground

Recorded habitat: Lowland and foothill rainforest, including rainforest patches

Survey methodology: 2. Dawn and dusk observation

Undertake repeated observation from safe vantage points overlooking the canopy, rainforest edges and proposed work areas.

Schedule observations around first light and late afternoon, when the species may be seen flying above forest and calling.

Record every detection, including the time, location, flight direction, behaviour, sex if identifiable, group size and whether the bird enters or leaves a hollow.

Do not rely on a silent or visually difficult survey period as evidence that the species is absent.

Documented detection period: First light and other daylight periods, with loud calls and flight above forest reported

Survey methodology: 3. Call and canopy searches

Use quiet listening periods during daytime searches to detect the species' high-pitched squawks, whistles, screeches and lower rasping calls.

Search the canopy and upper forest edge because males are mainly green and females are mainly red with a violet or blue belly, making sex-specific identification possible at close range.

Treat a call-only record as a valid detection only when the observer records the call type, direction, location and survey conditions clearly.

Do not use call playback unless it is permitted by the relevant state authority and approved in the project survey plan.

Survey methodology: 4. Effort design and reporting

There is no species-specific survey effort, number of nights, transect length or trap effort specified in the supplied documents.

Set survey effort according to the size and condition of the habitat, the amount of mature hollow-bearing forest proposed for clearing, access and visibility, and the likelihood of canopy disturbance.

Include surveys during the documented breeding period of April to September when works could affect nest hollows, and consider additional surveys outside that period where habitat is suitable.

Do not use cage trapping or other capture methods for this canopy parrot unless a suitably authorised wildlife professional has prepared and approved the method.

Documented breeding period: April to September

Species-specific trapping effort in supplied documents: Not specified

• Record survey dates, start and finish times, weather, observers, routes, vantage points, equipment, area searched and detection conditions.
• Map all records and all potentially suitable hollow-bearing trees, including trees where no bird is observed.
• Submit confirmed records and relevant negative survey information to the relevant state wildlife database.
• Report the taxonomy used in the record because the species was formerly grouped with other Eclectus forms under the Eclectus Parrot.

Before habitat disturbance: Avoid and minimise

Plan around the species' dependence on rainforest canopy, mature hollow-bearing trees and connected habitat. The Australian form occurs in the tip of Cape York Peninsula and is associated with rainforest patches in the Iron and McIllwraith ranges. [Sources support this section:

• Retain rainforest patches, mature canopy trees and all suitable hollow-bearing trees wherever practicable.
• Retain connected forest and canopy flight routes between rainforest patches and retained habitat.
• Avoid removing trees with hollows approximately 20 to 30 metres above ground, particularly during the April to September breeding period.
• Keep machinery, spoil, lighting and unnecessary personnel out of retained rainforest and hollow-bearing trees.
• Design the work footprint to avoid narrow rainforest remnants and isolated retained trees that are exposed to wind, heat or edge effects.

Before habitat disturbance: Approvals and planning

• Confirm the current state listing and obtain any Queensland permits or approvals required before disturbing the species, its habitat or a nest.
• Confirm whether an EPBC Act referral or approval is required, noting that the supplied project information identifies the species as not listed under the EPBC Act.
• Prepare a fauna management plan that identifies survey results, habitat trees, exclusion areas, fauna handling responsibilities, stop-work triggers and reporting requirements.
• Stage clearing so that retained habitat remains available while each work area is checked and released.

Before habitat disturbance: Site preparation

• Complete a pre-clearance inspection of the approved footprint immediately before works begin.
• Mark retained rainforest, hollow-bearing trees, nest trees, buffers and access limits in the field so machinery operators can identify them.
• Use exclusion fencing where it can protect retained habitat and does not create a hazard for flying or ground-moving fauna.
• Brief machinery operators on the species' green males, red females, loud calls, high canopy use and the requirement to stop when directed by the fauna spotter catcher.
• Confirm the location of the nearest veterinarian, wildlife carer and authorised fauna handler before clearing starts.

During habitat disturbance: Daily controls

Clearing should proceed slowly enough for the fauna spotter catcher to inspect trees, canopy activity and fallen habitat features. Work must stop when an animal, nest or previously unrecorded habitat feature could be affected.

• Inspect the work area each day before machinery starts and after any overnight change in conditions.
• Keep the fauna spotter catcher in clear communication with the operator and position the spotter where the canopy, tree base and drop zone can be seen safely.
• Clear in staged sections, retain an escape route to nearby retained forest and avoid pushing fauna towards roads, machinery or isolated habitat.
• Limit unnecessary noise, night lighting and personnel movement near retained rainforest and known nest trees.
• Maintain exclusion fencing, tree markings and access controls throughout the work period.

During habitat disturbance: Habitat feature handling

• Stop work and reassess any tree containing a hollow, nest, roosting bird or other sign of use before felling or trimming it.
• Do not fell or disturb a suspected nest tree until the fauna spotter catcher and the authorised environmental representative have confirmed the action is permitted.
• Lower hollow-bearing limbs and trunks in a controlled manner where approval allows removal, and retain them on site if they can provide replacement shelter.
• Inspect fallen branches, logs, rocks, leaf litter and disturbed ground for animals before machinery enters the area.
• Do not relocate hollow material, logs or other habitat features beyond the approved project area without ecological direction and any required approval.

During habitat disturbance: If an animal is found

• Stop the activity that could affect the bird and give it a clear route to nearby retained forest.
• Do not chase, corner, handle or release the bird unless the person is authorised and trained under the relevant state requirements.
• Use a suitably authorised fauna handler for any capture or relocation, and release a healthy bird into nearby suitable retained habitat approved by the project ecologist.
• Place an injured bird in a suitable ventilated carrier, keep handling and noise to a minimum, and transfer it promptly to a veterinarian or licensed wildlife carer.
• Suspend work if a bird is injured, trapped, unable to leave safely, repeatedly returning to the work zone, or found using a hollow or nest that could be affected.
• Record the location, time, condition, action taken, handler, release or treatment location and outcome.

After habitat disturbance: Completion checks

Post-clearing checks should confirm that no fauna remains trapped and that retained rainforest and habitat trees have not been damaged. Follow-up should focus on known records, nest trees, retained canopy and any relocation outcome.

• Inspect the cleared area, retained tree bases, felled material, machinery exclusion zones and access tracks for trapped, injured or displaced fauna.
• Recheck retained hollow-bearing trees and nearby canopy for damage, vibration impacts, exposed hollows or signs of continued use.
• Confirm that all fauna incidents, sightings, releases, treatments, mortalities and stop-work events are recorded before the work area is signed off.
• Remove temporary exclusion fencing only when the environmental representative confirms that the area is safe and no further staged work is planned.

After habitat disturbance: Monitoring and reporting

• Monitor retained rainforest, known nest trees and replacement habitat during the project monitoring period set by the approval or fauna management plan.
• Use the same mapped locations and observation method for repeat checks so changes in occupancy, canopy use and hollow use can be identified.
• Report confirmed records, injuries, deaths, nest disturbance, permit breaches and unexpected impacts to the relevant project authority and state wildlife database where required.
• Review the fauna management plan if birds continue to enter the work area or if retained habitat becomes unsafe.

After habitat disturbance: Offsets and residual impacts

• Apply any offset, rehabilitation or compensatory habitat requirement imposed by the relevant approval or Queensland authority.
• Do not treat relocation of an individual bird as a substitute for retaining rainforest, connected canopy and mature hollow-bearing trees.

Rehabilitation actions: Vegetation and habitat structure

Rehabilitation should recreate connected rainforest canopy and retain or replace the tree hollows on which breeding depends. The supplied documents identify rainforest habitat, fruit and plant material in the diet, and high nest hollows, but do not specify a planting list or nest-box design.

• Replant cleared areas with locally appropriate native rainforest species from the project site's reference community, using species that will develop a continuous canopy and provide fruit, seeds, buds, blossoms or nectar.
• Prioritise links between retained rainforest patches and isolated mature trees so birds can move through connected canopy.
• Retain standing dead trees and fallen timber where they do not create a safety or fire hazard, because they can provide shelter and support broader fauna habitat.
• Control weeds that suppress rainforest regeneration and maintain ground conditions that allow native canopy plants to establish.

Rehabilitation actions: Hollows and replacement structures

Recorded nest hollow height: 20 to 30 metres above ground

Recorded clutch size: Typically two eggs

• Retain all safe hollow-bearing trees and protect them from fire, machinery impact, soil compaction and unnecessary pruning.
• Where an approved removal is unavoidable, retain suitable hollow-bearing limbs or trunks on site and install replacement nest structures only under advice from the project ecologist and relevant authority.
• Locate replacement hollows in or beside retained rainforest and monitor them for use, damage and maintenance needs.
• Do not assume that a nest box replaces a mature tree hollow, because the supplied documents identify natural hollows as scarce and important breeding sites.

Rehabilitation actions: Monitoring and management

• Monitor planted rainforest survival, canopy development, hollow condition, nest-box use, weed cover and bird detections against measurable targets in the rehabilitation plan.
• Use repeat dawn or daylight observations and call records to assess whether Papuan Eclectus returns to retained or rehabilitated habitat.
• Manage fire so that retained rainforest, mature hollow-bearing trees and regenerating canopy are not exposed to damaging fire intensity or repeated burning.
• Control introduced predators and other threats where they are identified by the project risk assessment and approved management plan.
• Investigate any failure of plant establishment, hollow replacement or bird use, then revise watering, weed control, fire protection or habitat works.
