Little Pied Cormorant (Microcarbo melanoleucos)

The Little Pied Cormorant is a small black and white waterbird found across most of Australia, from inland wetlands to estuaries and the coast. It breeds in colonies, sometimes with other waterbirds, so clearing, construction, vegetation removal and changes to water levels can affect many birds at one site. It is listed as least concern in Australia, but Queensland treats it as a least concern colonial breeder, and disturbing its breeding place requires a high risk species management program.

Conservation status

Queensland, Nature Conservation Act 1992: Colonial breeder. Least concern in Queensland, but it breeds in colonies, so tampering with a breeding place needs a high risk species management program rather than the low risk program.

Breeding season

The Little Pied Cormorant breeds in colonies, or less often as single pairs. In southern Australia, nesting is recorded across spring and summer, while in tropical areas it is linked to the wet season and may occur in late summer.

Breeding mode: Colonial breeder, with occasional single pairs. Breeding colonies may occur in wetland trees, flooded forest, lake islands and dense vegetation near or over water. Both adults incubate eggs and care for young. [S1, S2, S6, S7, S8]

Nest and breeding place: A flat platform of sticks and twigs, lined with green leaves. Nests are usually in trees, including trees standing in water, small bushy trees, paperbarks, she-oaks, eucalypts and other vegetation near or over water. [S1, S6, S7, S8]

Colony size and density: Recorded colonies contained up to 41 active nests, and approximately 68 nests were recorded at Lake Clarendon. Nests may be clustered less than 1 m apart. [S7, S8]

Clutch size: 3 to 5 pale blue eggs. [S6, S7, S8]

Incubation: Both adults incubate the eggs. Incubation duration: Not recorded. [S1, S2, S6, S7]

Fledging and dependence: First flight has been observed at around 39 days in one Western Australian study. Fledging duration and the period of post-fledging dependence are not recorded. [S7]

Breeding frequency and maturity: Breeds once a year. Age at sexual maturity: Not recorded. [S3, S8]

Timing can shift between years and regions, particularly where breeding follows rainfall, monsoon conditions, flooding or changes in wetland water levels; inspect trees, islands and dense vegetation for active nests before works.

  • Breeding and nesting, southern Australia: Plan for active nests from spring through summer, especially around wetland trees, islands and dense vegetation over water.
  • Breeding and nesting, tropical Australia and Northern Territory: Breeding is associated with the wet season and is recorded as occurring in late summer in the Northern Territory.
  • Eggs, nestlings and dependent young: Treat active colonies as occupied while adults attend nests, eggs or young are present, even if nests are partly hidden in vegetation.
  • Local presence and foraging around wetlands: The species is resident and may use freshwater, brackish and marine waters throughout the year, including ponds, creeks, dams, lakes, estuaries and rivers.
  • Colony and breeding place disturbance risk: Avoid clearing, tree removal, high noise, access through vegetation and water-level changes near active colonies during the breeding period, and confirm occupancy before works.
  • Highest clearing risk: The highest risk is during spring and summer nesting in southern Australia, with late summer risk in tropical and Northern Territory colonies.

Identification: Appearance

The Little Pied Cormorant is a small cormorant with a black back and white underparts. It is often seen perched on a branch with its wings spread to dry.

Adults have glossy black upperparts, a white face and white underparts. The white usually extends above the eye, giving a pale eyebrow appearance.

The bill and bare skin around the face are yellow. The legs and feet are black. A short black crest may be visible on the forehead.

  • Length about 56 to 58 cm
  • Short, yellow bill
  • Long, wedge-shaped black tail
  • White thighs and underparts
  • Immature birds are duller and may have a black flank mark

Identification: Calls and similar species

Calls include a low coo during courtship. Nesting birds may give a soft oo-oo sound. A croaking tuk-tuk-tuk call may also be heard.

The Little Pied Cormorant can occur with the similarly sized Little Black Cormorant. The Pied Cormorant is larger, has a long ivory bill and has contrasting black flank feathers near the legs.

Identification: Field signs

Look for birds perched on branches, dead trees, posts, rocks or structures beside water. Wing spreading after diving is a useful behaviour to record.

Nests are flat platforms made from sticks and green leaves. In colonies, fresh green nest material, whitewash, feathers, faecal staining and repeated adult activity may be visible below or around the nesting trees.

A strong bird odour, concentrated droppings and repeated calls can indicate a colony even when nests are hidden deep in vegetation.

Distribution: Australian range

The Little Pied Cormorant is widespread across Australia and is common in suitable wetland habitat. It occurs in both freshwater and saltwater environments, but is absent from the most arid parts of inland Western Australia.

The species is mapped in New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria and Western Australia. It occurs across mainland Australia and Tasmania, including inland waters, coastal wetlands and estuaries.

  • Freshwater lakes, dams, swamps and lagoons
  • Rivers, creeks and open waterways
  • Estuaries and sheltered coastal waters
  • Islands and wetland margins

Distribution: Regional breeding patterns

Breeding has been recorded in south eastern Queensland, inland New South Wales, Western Australia and the Northern Territory. Timing varies with region and water conditions.

In southern areas, nesting is generally in spring and summer. In the Northern Territory, nesting may occur in late summer during the height of the wet season.

Distribution: Wider range

The species also occurs in New Zealand, New Caledonia, the Solomon Islands, Wallacea, lowland New Guinea and nearby islands. Some non breeding birds have been recorded in Java and Bali.

Habitat: Waterbodies and wetland structure

On a works site, search all permanent and temporary waterbodies, including small ponds, dams, creeks and flooded vegetation. The species can use fresh, brackish and marine water, provided there is suitable feeding habitat and a nearby perch or nesting tree.

The species uses wetlands, swamps, lakes, lagoons, dams, rivers, creeks, estuaries and sheltered coastal waters. It may occur on waterbodies of almost any size.

On inland streams and dams, birds may be solitary. Larger open waterways and coastal areas can hold flocks.

  • Open water with shallow margins
  • Wetland islands and peninsulas
  • Trees or shrubs standing in water
  • Branches overhanging water
  • Flooded forest and dead trees left after water levels rise

Habitat: Vegetation to inspect

Inspect trees, shrubs and dense vegetation near or over water. Nesting has been recorded in eucalypts, she-oaks, paperbarks, bottlebrushes, willows, oleanders, peppermint trees and other trees with suitable forks and branches.

Colonies may be tucked deep inside vegetation and can be difficult to see from the bank.

Habitat: Site inspection priorities

Before clearing or construction, inspect wetland margins, islands, stands of dead flooded trees and trees overhanging water. Also check nearby branches used for drying, resting or observing feeding areas.

A lack of visible nests does not confirm that a site is unused. Repeat observations may be needed where vegetation is dense or water levels have recently changed.

Foraging habitat: Feeding areas

The Little Pied Cormorant catches prey underwater and usually feeds in shallow water or close to shore. Feeding birds may be solitary even when a colony is nearby.

Search open water, shallow edges, creek pools, dam margins, estuaries and sheltered coastal water. Birds may dive from the water surface and return with prey before swallowing it.

Important feeding areas can extend beyond the nesting trees, so works should be assessed across the connected wetland and drainage system.

  • Shallow pools and muddy margins
  • Creek channels and backwaters
  • Dam and lake edges
  • Estuarine flats and sheltered bays
  • Areas with crayfish, yabbies, fish, shrimps and other aquatic animals

Foraging habitat: Foraging behaviour

The species is a benthic feeder and commonly dives for prey near the bottom. Typical dives last about 15 to 20 seconds, followed by about 5 to 10 seconds at the surface before another dive.

It may place a fish on the surface to turn it before swallowing it head first. Birds repeatedly diving in one area may identify a local feeding concentration.

Foraging habitat: Water management

Drainage changes, dewatering, sediment movement, pollution and altered water levels can reduce prey availability or make feeding areas unusable. Consider both the immediate work area and downstream or connected wetlands.

Flooding can create nesting habitat by leaving trees standing in water. Receding water can make nest trees unsuitable, especially where trees are left on dry ground.

Breeding habitat: Nest trees and vegetation

The Little Pied Cormorant breeds in colonies or, less commonly, as single pairs. Its nest is usually a flat stick platform in a tree over or close to water.

Look for nests in small, bushy trees, eucalypts, paperbarks, she-oaks and other trees with forks or dense branches. Nests may be on islands, at wetland margins or in dead trees standing in water.

At one Queensland site, nests were 1 to 6 m above water level. Nests were generally less than 1 m apart, making the colony easy to disturb if work enters the nesting trees.

Breeding habitat: Nest construction

Nests are built from twigs and sticks and lined or edged with green leaves. Paperbark twigs may form a dense upper platform.

Fresh greenery around a nest edge suggests recent construction. Both adults incubate the eggs and care for the young.

  • Clutch usually 3 to 5 pale blue eggs
  • Nests commonly clustered close together
  • Most observed nests had 2 or 3 nestlings
  • Young may move to an adjacent nest or nearby branch

Breeding habitat: Breeding timing and work planning

In southern Australia, plan for nesting during spring and summer. In tropical regions, nesting may follow the monsoon. Northern Territory nesting has been recorded in late summer during the wet season.

Where practicable, schedule tree removal, vegetation clearing, piling, drilling and high noise works outside the local nesting period. Confirm local timing with a qualified ecologist because rainfall and water levels can shift breeding activity.

Breeding habitat: Active breeding place

Treat a site as active when adults are attending nests, eggs or young are present, fresh green nest material is being added, or young are moving between nests and nearby branches.

Do not rely on a quick visual check from the ground. Use binoculars or a suitable observation point and avoid entering dense nesting vegetation.

Sheltering habitat: Roost and drying sites

Outside feeding periods, Little Pied Cormorants use branches, trees and other structures beside water for resting and drying. Roosts may be separate from the breeding colony and should be checked before works begin.

Look for birds on branches overhanging water, dead trees, exposed limbs, coastal rocks and other elevated perches. Birds commonly spread their wings after diving to dry them.

Repeated use of one perch may be shown by whitewash, faecal staining, feathers and worn or bare branches.

  • Branches over water
  • Dead flooded trees
  • Wetland islands
  • Trees and shrubs at lake or dam margins
  • Coastal rocks and quiet shoreline structures

Sheltering habitat: Roost disturbance

Sudden approach, machinery, boats, dogs, drones and people entering the water margin can flush resting birds. Repeated flushing can make a site unsuitable and can increase energy use, particularly when birds are also feeding young.

Keep workers, machinery, vehicles and access tracks away from regularly used perches where practicable. Use existing access routes and avoid parking or staging equipment beneath roost trees.

Sheltering habitat: Survey approach

Observe from outside the wetland margin where possible. Record the location of birds, the direction of flight, repeated perch use and any colony or nest trees.

At a Queensland nesting study, chicks older than about two weeks were not approached closer than about 30 m. Use this as a minimum field reference for observation of older chicks, and set a larger precautionary exclusion area where birds show repeated alarm or flushing.

Colonies and breeding places: What a colony looks like

A Little Pied Cormorant colony is a group of closely spaced stick nests in trees or shrubs beside or over water. Colonies can be mixed with herons, ibises, spoonbills, darters and other cormorants, so one breeding place may support many waterbirds at once.

Colonies may occur on wetland islands, in trees standing in water, along lake margins or in dense vegetation near water. Nests can be hidden from view, with adults nearly touching each other in closely packed trees.

Recorded colonies have included up to 41 active Little Pied Cormorant nests. One Queensland colony had about 68 nests in December 1997. Colony size can vary between sites and seasons.

Colonies and breeding places: Recognising an active colony

Look for repeated adult attendance, fresh green nest material, eggs, nestlings, young on branches, concentrated droppings and faecal staining on nest trees and the ground or water below.

Repeated calls, birds carrying sticks or leaves, and adults flying to the same stand of trees are useful signs. Survey from a distance first, then use binoculars rather than entering the colony.

Colonies and breeding places: Disturbance and flushing risk

People, machinery, clearing, tree felling, boats, drones, dogs, bright lights and sudden noise can flush adults from nests. Exposed eggs and young may then be vulnerable to heat, cold, predation or falling from the nest.

Keep works outside the nesting period where possible. If active nests are present, stop work near the colony and obtain ecological and regulatory advice before changing the site, removing vegetation or altering water levels.

  • Do not fell or prune nest trees while a colony is active
  • Do not enter islands or dense nesting vegetation for routine work
  • Keep access, laydown areas and lighting away from colony trees
  • Use a clearly marked buffer set by the project ecologist
  • Monitor for flushing when work occurs nearby

Colonies and breeding places: Colony protection and water management

Protect the whole breeding place, not only the individual nest trees. Include nearby roosts, flight paths, feeding water and the wetland area that supports prey.

Flooding can create nesting habitat by leaving trees standing in water. Falling water levels can leave nest trees dry and cause them to be abandoned. Avoid sudden dewatering, drainage changes, sediment release and pollution during the breeding period.

Threats: Clearing and construction

The Little Pied Cormorant is widespread and listed as least concern, but local colonies can be affected quickly by works or changes to wetlands. Management should focus on preventing disturbance to active nests, protecting wetland function and retaining suitable trees and perches.

Tree removal, pruning, earthworks, access tracks, piling, cranes and high noise can destroy nests or cause adults to abandon eggs and young. A colony may be difficult to detect when nests are concealed in dense foliage.

Complete a targeted inspection before clearing. Retain nest trees, nearby wetland vegetation, roost branches and safe access routes wherever practicable.

Threats: Disturbance and flushing

Repeated flushing can reduce feeding time and expose eggs and young. Disturbance can come from machinery, workers, vehicles, boats, recreational users, dogs, drones and night lighting.

Use exclusion fencing, low disturbance access, quiet work methods and a site induction. Stop and reassess if adults repeatedly leave nests, circle the colony, call continuously or fail to return.

Threats: Water and wetland impacts

Dewatering, altered flows, pollution, sedimentation and rapid changes in water level can remove feeding habitat, reduce crayfish and fish availability, or leave nest trees dry.

Maintain water quality and natural wetland connections where possible. Plan drainage, pumping and flood management with the colony, roost and feeding area considered together.

Threats: Queensland regulatory requirement

In Queensland, the Little Pied Cormorant is a least concern colonial breeder. Tampering with its breeding place requires a high risk species management program under the Nature Conservation (Animals) Regulation 2020, rather than the low risk program used for other least concern animals.

Before work near a suspected colony or active breeding place, confirm the approval pathway with the relevant Queensland regulator and the project ecologist. Do not disturb, relocate or destroy nests without the required authorisation and management measures.

Survey methodology: 1. Desktop assessment

Survey for Little Pied Cormorants wherever works may affect wetlands, dams, lakes, rivers, estuaries, islands or trees standing in water. Give extra attention to dense vegetation, flooded trees and established waterbird colonies, as nests can be concealed and closely clustered.

Map all waterbodies, drainage lines, wetland vegetation, islands, flooded trees and nearby construction access routes.

Review recent records and aerial imagery for colonies, heronries, communal roosts and suitable nesting trees.

Check whether the site supports other colonial waterbirds. A mixed colony may contain Little Pied Cormorants even when the species is not obvious from a distance.

Check the proposed works against current Commonwealth and state requirements before setting the survey scope.

Typical nest setting: Flat stick platforms lined with green leaves, usually in trees or small bushy trees over or beside water.

Recorded colony sizes: Up to 41 active nests in a Western Australian study, and approximately 68 nests at Lake Clarendon in December 1997.

  • Include trees and vegetation within and overhanging water, not only trees scheduled for removal.
  • Treat an established colony as a recurring sensitive site. Confirm current occupancy before each breeding-season work program.
  • Consider Queensland breeding-place provisions where works may tamper with a breeding place.

Survey methodology: 2. Field detection

Search from the waterbody edge, public access points, boats where authorised, or other locations that avoid entering the colony.

Use binoculars or a spotting scope to scan tree forks, dense vegetation, dead flooded trees, islands and lake margins.

Look for black and white cormorants, yellow bills, adults carrying sticks or greenery, fresh green nest material, eggs, nestlings and fledglings.

Listen for low cooing during courtship and soft calls from nesting birds. Do not rely on calls alone.

Nest spacing recorded at Lake Clarendon: Nests were generally less than 1 m apart.

Recorded nest height at Lake Clarendon: Approximately 1 to 6 m above water level.

  • Search for adults perched with wings spread, feeding near shore, or travelling to and from a colony.
  • Scan adjoining trees and branches for young birds, including recently fledged birds standing to dry their wings.
  • Record possible nests from a distance before approaching or changing position.

Survey methodology: 3. Timing and effort

Survey during daylight, when adults are more likely to be visible on nests, branches or water. Use more than one observation period where vegetation, glare or distance limits detection.

Plan surveys around the local breeding season. Breeding was recorded in spring and summer in south eastern Queensland, spring and summer at Toowoomba, summer in inland New South Wales, and late summer during the wet season in the Northern Territory. Southern Australian breeding is also described as spring or early summer, while tropical breeding can follow the monsoon.

Repeat the survey after substantial water-level changes, flooding, vegetation clearing or a long delay before works begin.

There is no defined Australian migration schedule for this species. Do not assume that an empty colony is permanently unused.

  • Avoid entering a colony to improve detection.
  • Use a distant observation point and allow birds to settle before counting.
  • Schedule follow-up checks when water levels or access conditions have changed.
  • Increase effort where nests are concealed, colonies are mixed, or dense vegetation prevents a complete count.

Survey methodology: 4. Records and mapping

Map the colony, individual nest trees, roost trees, access points, water levels and proposed work footprint.

Record the date, start and finish time, weather, observer position, survey method, visibility, water conditions and any limitations.

Record the number of adults, occupied nests, nests with eggs, nests with young, fledged young, birds entering or leaving, and signs of disturbance.

Describe the response of birds to the observer. Record alarm calls, repeated circling, nest departure, flushing or abandonment risk.

  • Photograph nests only from a distance and where this does not cause disturbance.
  • Record whether the site is a single pair, a colony, or a mixed waterbird colony.
  • Mark uncertain observations as unconfirmed and arrange a follow-up check rather than approaching the nest.
  • Share mapped sensitive locations with the project manager, spotter catcher and relevant regulator.

Before habitat disturbance: 1. Approvals and work planning

Avoid the breeding place wherever practicable. Complete approvals, surveys, inductions and exclusion controls before vegetation removal, water-level changes, piling, drilling, lighting installation or other noisy works begin.

Confirm whether the action could significantly affect a matter of national environmental significance and whether an EPBC Act referral or approval is required.

For Queensland projects, treat the Little Pied Cormorant as a least concern colonial breeder. Tampering with its breeding place requires the high risk species management program pathway under the Nature Conservation (Animals) Regulation 2020, rather than the low risk pathway used for other least concern animals.

Check state and territory wildlife approvals, scientific permits, animal ethics requirements and land manager permissions before survey, handling, relocation or nest intervention.

Obtain written approval for any action that may disturb, remove, damage or alter an active breeding place. Confirm conditions with the relevant regulator before mobilisation.

  • Nominate one person to maintain the approval register.
  • Include colony protection, water management and lighting controls in the construction environmental management plan.
  • Stop work and seek advice if the approved footprint or method changes.
  • Do not assume a least concern listing removes breeding-place controls.

Before habitat disturbance: 2. Avoidance and timing

Retain active nest trees, adjoining vegetation, access to water and the structure of the colony wherever possible.

Keep clearing, pruning, piling, demolition and high-noise work outside the local nesting period where practicable. In many southern areas this means avoiding spring and early summer. In tropical areas, check the local post-monsoon pattern.

Plan water-level changes, dam drawdown, flood management and bank works so they do not strand or isolate a colony or expose nest trees during breeding.

Do not schedule works beside an active colony simply because adults are temporarily absent.

  • Use existing tracks and access points rather than creating new approaches through nesting vegetation.
  • Retain islands, flooded trees, small bushy trees and vegetated lake margins where they support nests.
  • Stage works so the colony retains quiet water and foraging habitat.
  • Recheck the site if works are delayed into a different season.

Before habitat disturbance: 3. Buffers and exclusion zones

Set a site-specific no-go area around the colony, nest trees, roost trees and approach routes. The fauna ecologist should define the buffer using colony size, line of sight, terrain, vegetation, machinery type, noise and bird behaviour.

Use a larger buffer where birds flush, repeatedly circle, call sharply, leave nests unattended or cannot settle. A fixed distance should not replace behavioural assessment.

At Lake Clarendon, chicks older than approximately two weeks were not approached closer than approximately 30 m during study work. This is an example of a research approach distance, not a universal construction buffer.

Fence or mark the exclusion area before plant arrives. Keep workers, vehicles, drones, boats and materials outside it.

  • Use high visibility fencing and signs that identify the area as an active colonial waterbird breeding place.
  • Maintain clear flight paths between the colony, water and foraging areas.
  • Keep lighting directed away from nests and roosts.
  • Review the buffer after rain, flooding, vegetation removal or any flushing event.

Before habitat disturbance: 4. Induction and pre-clearance check

Complete a pre-clearance inspection immediately before works. Check trees, dense vegetation, islands, water edges, culverts, bridges and other structures that may hold birds or nests.

A qualified fauna ecologist should confirm whether the place is active and whether the approved controls remain suitable.

Induct all workers, operators, supervisors, boat crews and fauna spotter catchers before entry.

Explain the stop-work process and show photographs or maps of the exclusion area.

  • Tell workers not to approach, photograph, feed or handle birds.
  • Tell workers to report any nest, fledgling, injured bird, unusual bird behaviour or colony movement immediately.
  • Mark approved clearing limits on the ground and in plant operator maps.
  • Keep a spotter catcher or fauna ecologist available whenever works are near the exclusion area.

During habitat disturbance: 1. Sequential clearing and supervision

Work from the least disturbing area towards the approved footprint. The spotter catcher has authority to stop work whenever a bird, nest, colony, roost or unexpected breeding place is found.

Clear low-risk areas first and leave water edges, nest trees, dense colony vegetation and adjoining escape habitat until the last practicable stage.

Use a staged approach for vegetation removal. Inspect each stage before the next stage starts.

Keep machinery speed low near water and avoid sudden movement, unnecessary alarms and repeated passes.

Maintain the approved buffer throughout the work, including during crane operation, piling, night works and material delivery.

  • Use a fauna spotter catcher with clear sight of the work face.
  • Stop work if birds begin repeated flushing or show alarm behaviour.
  • Do not fell a tree containing a nest unless the action is specifically authorised and the fauna ecologist has confirmed the method.
  • Prevent sediment, oil, concrete washout and debris from entering breeding or foraging water.

During habitat disturbance: 2. Response to a colony or breeding place

Stop work immediately if an active nest, colony, communal roost or dependent young bird is found inside or near the work area.

Withdraw people and plant to a safe distance without chasing or surrounding birds.

Keep the site quiet while the fauna ecologist identifies the species, assesses activity and checks the approval conditions.

Contact the project manager and relevant regulator or wildlife authority if the find is outside the approved controls or requires handling, relocation or damage to the place.

  • Treat a nest as active when it has an attendant adult, eggs, young, fresh nest material or other evidence of current use.
  • Do not remove eggs, nestlings, nest material or a nest tree without explicit authority.
  • Do not attempt to make birds leave a colony so works can proceed.
  • Record the event, photographs, location and immediate actions.

During habitat disturbance: 3. Handling and animal welfare

Only authorised and appropriately trained personnel may capture, handle, contain or relocate a Little Pied Cormorant.

Avoid capture whenever the bird can be protected in place. Cormorants can be stressed by restraint and may injure themselves if handled poorly.

Use a suitable ventilated container, keep the bird cool, quiet and upright, and minimise handling time if capture is authorised.

Do not release a bird into an unfamiliar waterbody without approval and ecological advice.

  • Keep people and dogs away from a contained bird.
  • Do not offer food or water unless directed by a wildlife rehabilitator or veterinarian.
  • Contact the designated wildlife rehabilitator or veterinarian for an injured, entangled, contaminated or exhausted bird.
  • Record the name and authority of the person who handled the bird, the time, location, condition, transport and destination.

During habitat disturbance: 4. Injured or displaced bird pathway

Stop the immediate hazard and establish a quiet exclusion area around the bird.

Notify the fauna spotter catcher, project manager and approved wildlife contact. Seek veterinary or wildlife rehabilitator advice promptly.

If a fledgling is uninjured, observe from a distance first. Parents may be nearby and repeated human approach can prevent reunification.

Do not return a bird to a nest or colony unless an authorised person has assessed the situation and approved the action.

  • Keep machinery and workers away from the bird's line of movement.
  • Use a trained person to assess entanglement, bleeding, weakness, collision injury or exposure.
  • Document whether the bird was released, transferred for care or found dead.
  • Report any suspected breach of an approval or breeding-place condition through the project incident process.

After habitat disturbance: 1. Immediate post-clearance check

Close out each work stage with a fauna inspection and a record of what happened. Post-clearance checks should confirm that no birds, nests, dependent young or injured animals remain at risk and that the colony has not been isolated from water or foraging habitat.

Inspect the completed work area, retained trees, exclusion fencing, water edge and access routes before demobilising the fauna team.

Check for injured birds, displaced fledglings, fallen nests, trapped animals, exposed eggs, damaged nest trees and newly created hazards.

Confirm that sediment controls, waste storage, lighting, fencing and machinery have not encroached on the breeding place.

Remove temporary hazards only when doing so will not disturb active birds or nests.

  • Complete the check in daylight where safe and practical.
  • Use binoculars to inspect retained trees and islands without entering the colony.
  • Check culverts, pits, trenches and temporary water-control structures for trapped fauna.
  • Escalate any active breeding place found after works started.

After habitat disturbance: 2. Monitoring and follow-up

Set follow-up observations where works occurred near a colony, nest tree, roost or important waterbody.

Monitor adult attendance, nest condition, young, fledglings, colony distribution, water access and signs of repeated disturbance.

Repeat checks after major rainfall, flooding, water-level changes, storms, tree failure or changes in construction activity.

Use the same observation points and recording method where possible so changes can be compared.

  • Keep observers outside the agreed buffer.
  • Record flushing, alarm behaviour, nest abandonment, reduced attendance and unusual mortality.
  • Continue monitoring for the period specified in the approval or management plan.
  • Ask the fauna ecologist to review whether controls need to be strengthened.

After habitat disturbance: 3. Relocated or treated animals

Confirm the outcome for every animal captured, treated, relocated or transferred to care.

Record the release location, release condition, date, time, person responsible and any identification or tracking details authorised for use.

Check whether released birds can access suitable water, cover and foraging habitat without entering the active work area.

Report deaths, failed releases, repeat injuries or return of birds to the hazard area.

  • Do not move a colony or nest site without a species-specific approved plan.
  • Use the shortest practicable transport route and an authorised wildlife care provider.
  • Record the fate of eggs, nestlings and adults separately.
  • Include photographs and veterinary or rehabilitation advice in the project file.

After habitat disturbance: 4. Reporting and incident review

Provide the land manager, project ecologist and regulator with the required survey, incident and monitoring records.

Review every stop-work event, bird injury, nest impact, colony disturbance and approval non-conformance.

Identify the immediate cause, such as inadequate fencing, poor visibility, changed water levels, plant movement or incomplete induction.

Update maps, method statements, buffers and induction material before the next work stage.

  • Keep a register of active breeding places and all fauna interactions.
  • Record dates, locations, people involved, actions taken and outcomes.
  • Use lessons from the incident to revise the construction environmental management plan.
  • Close the incident only after the fauna ecologist confirms that residual risks are controlled.

Rehabilitation actions: 1. Restore nesting and roosting habitat

Rehabilitation should restore quiet water, suitable nesting vegetation and safe access to feeding areas. Design replacement habitat for Little Pied Cormorants rather than relying on generic fauna structures that do not suit a tree-nesting waterbird.

Retain mature trees, flooded trees, small bushy trees, paperbarks, she-oaks, eucalypts and other vegetation that can support stick platforms near water.

Restore vegetated islands, lake margins and sheltered water edges where these are part of the colony setting.

Replace removed vegetation with locally appropriate native species and protect plantings from erosion, grazing and vandalism.

Allow enough time for replacement trees to develop structure before treating them as breeding habitat.

  • Prioritise sites with reliable water, quiet access and nearby foraging habitat.
  • Retain dead trees standing in water where safe and permitted, as they can provide nesting structure.
  • Do not simplify a colony site into open lawn or hard bank.
  • Keep rehabilitation works outside the active nesting period where practicable.

Rehabilitation actions: 2. Replacement nest structures

Use artificial nest platforms or other nest structures only where a fauna ecologist confirms that natural nesting trees cannot be retained and the design is suitable for local conditions.

Base the design on the species' natural nest, a flat platform of sticks and green leaves in a tree or bushy tree. Ensure the structure is stable, weather resistant and positioned above water or beside suitable water.

Place structures where birds can approach, land and depart without crossing work areas or exposed hazards.

Inspect artificial structures before and during the breeding season and repair them only when this will not disturb active birds.

  • Do not install bat boxes, hollows or terrestrial nest boxes as substitutes for Little Pied Cormorant nest platforms.
  • Do not install a replacement structure without checking approvals, land tenure, water-level changes and collision risks.
  • Use locally sourced natural nest material only where approved and free of weeds, pathogens and contaminants.
  • Treat a structure as a potential breeding place once birds begin using it.

Rehabilitation actions: 3. Water, weeds and site condition

Maintain water quality and suitable water depth around nesting and foraging areas, while allowing for natural flooding and seasonal water-level variation.

Prevent sediment, hydrocarbons, concrete washout, herbicides and construction waste from entering the wetland.

Control weeds without disturbing nests, roosts, bank stability or native cover. Use targeted methods and follow seasonal restrictions.

Restore shallow edges, aquatic vegetation and safe access to water where these have been damaged.

  • Coordinate water releases, pumping and drawdown with the fauna ecologist and land manager.
  • Keep artificial lighting away from colonies, roosts and flight paths. Use shielding and the lowest practical intensity.
  • Remove fishing line, wire, plastic and other entanglement hazards from rehabilitation areas.
  • Inspect after floods and storms for fallen trees, damaged platforms and blocked flight paths.

Rehabilitation actions: 4. Long-term monitoring

Monitor restored sites for vegetation survival, water condition, nest use, colony development, roost use and disturbance.

Compare use of natural and artificial nest structures without approaching active nests unnecessarily.

Track whether birds can move between the colony, water and feeding areas as vegetation and construction areas change.

Continue monitoring for the period set by approvals or the rehabilitation plan, and extend it where the colony is still establishing.

  • Record occupied structures, active nests, eggs, young, fledglings and signs of abandonment.
  • Use fixed distant observation points and consistent methods.
  • Review monitoring results after each breeding season.
  • Remove or modify structures that create hazards or are not used, but only after ecological and regulatory review.
