White-bellied Sea-eagle (Haliaeetus leucogaster)

The White-bellied Sea-eagle is a large raptor of Australian coasts, estuaries, rivers, lakes and wetlands. It matters on works sites because clearing, construction activity and people near nests can cause nest abandonment, reduce breeding success or remove important feeding habitat. It is an EVNT species, with state listings including Vulnerable in New South Wales and Tasmania, Endangered in Victoria and South Australia, and Priority 4 in Western Australia. It is protected wildlife in Queensland, with additional controls applying to interference with breeding places.

Conservation status

New South Wales, Biodiversity Conservation Act 2016: Vulnerable.

Victoria, Flora and Fauna Guarantee Act 1988: Endangered.

South Australia, National Parks and Wildlife Act 1972: Endangered.

Tasmania, Threatened Species Protection Act 1995: Vulnerable.

Breeding season

White-bellied Sea-Eagles breed across much of Australia, with activity generally extending from May to January. Timing varies between regions. South Australian laying is concentrated in July and August, while Tasmanian laying occurs from June to October.

Breeding mode: Monogamous pairs usually mate for life. Both adults defend a breeding territory and build or repair the nest.

Clutch size: Usually 1 to 2 eggs, commonly 2.

Incubation: Around six weeks.

Nestling period: Young remain in the nest for about 65 to 70 days. Other guidance records 65 to 85 days before young learn to fly.

Post-fledging dependence: Juveniles remain near their parents for several months while developing hunting skills.

Age at maturity: About 5 to 6 years, generally when adult plumage has been acquired.

Breeding frequency: Not recorded.

Timing can shift between years and regions, particularly between northern, southern, coastal and inland areas, so active nests and dependent young should be checked at the site before works begin.

  • Courtship, nest building and repair: Pair-bonding occurs throughout the year, with courtship and nest work increasing from mid-April and continuing through the breeding season.
  • Egg laying and incubation: Laying is recorded from June to September generally, with July and August the main laying months in South Australia.
  • Nestlings and dependent young: Nestlings are most vulnerable after laying and remain dependent after leaving the nest while they develop flight and hunting skills.
  • Post-fledging dispersal from the natal territory: Young birds may remain near their parents for several months and later leave the natal territory, but the timing of dispersal is not fixed.
  • Highest clearing risk: Avoid clearing and noisy construction near nests from May to December, with the highest risk during courtship, laying, incubation and early nestling stages.

Identification: Appearance and size

The White-bellied Sea-eagle is a large eagle with broad wings and a short, wedge-shaped or fan-shaped tail. Adults are strongly contrasting white and grey, while immature birds are mainly brown and can be difficult to identify.

Adults have a white head, breast, belly and leg feathering. The back and upper wings are grey, and the underwings are greyish black with a smaller white area along the leading edge.

The tail is grey at the base with a white tip. The bill is large, hooked and grey with a darker tip. The legs and feet are cream white, with long black talons.

Immature birds are predominantly brown with lighter or creamy markings. Adult plumage develops gradually over several years.

  • Length: 75 to 85 cm.
  • Wingspan: 180 to 220 cm.
  • Females are generally larger than males.

Identification: Calls and similar species

The species makes loud, goose-like honking calls. Breeding pairs may call together near the nest, especially during the breeding season. Juveniles make repeated begging calls.

Immature White-bellied Sea-eagles can be confused with Tasmanian wedge-tailed eagles and, when perched, swamp harriers. A White-bellied Sea-eagle has a shorter, pale tail and unfeathered, heavily scaled lower legs. Wedge-tailed eagles have feathered lower legs.

  • Use flight shape, habitat and behaviour with plumage when checking an identification.
  • Do not rely on a white adult head, as immature birds are mostly brown.

Identification: Field signs

Look for large stick nests in prominent trees, on cliffs, rock stacks, mangroves and isolated coastal structures. Nests may be reused and enlarged over many years.

Droppings, whitewash, feathers and discarded prey remains may occur below regular perches, feeding platforms and nest trees. These signs can indicate use, but they do not by themselves confirm that a nest is currently occupied.

A nest, guard roost or repeated flight path should be recorded and referred to a suitably experienced ecologist before clearing or construction proceeds.

Distribution: Australian range

The White-bellied Sea-eagle occurs around the Australian coastline, including Tasmania, and inland along major rivers, lakes, dams and wetlands. It is mapped in New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria and Western Australia.

In New South Wales it is widespread along the east coast and along major inland rivers and waterways. Indicative regions include the NSW North Coast, Sydney Basin, South East Corner, South Eastern Highlands, New England Tablelands, Riverina, Murray Darling Depression, Darling Riverine Plains, Cobar Peneplain, Mulga Lands, Nandewar and Brigalow Belt South.

In Tasmania it occurs around the coast, larger rivers, lakes, dams and estuaries. It is also recorded on many nearshore islands, including King Island, Flinders Island, Maria Island, Bruny Island and Bass Strait islands.

In South Australia it occurs along approximately 5,500 km of coastline, including the Great Australian Bight, Eyre Peninsula, Yorke Peninsula, Fleurieu Peninsula and Kangaroo Island. It also occurs along the River Murray system and associated wetlands.

  • The species is also recorded in coastal and inland areas of Queensland, Victoria, Western Australia and the Northern Territory.
  • It may be absent from parts of a mapped region, particularly where suitable water, prey and nesting habitat are lacking.

Distribution: Regional populations

The South Australian population is geographically isolated and sparsely distributed. Most South Australian pairs occur on offshore islands or remote coastal sites, and the mainland population has declined substantially.

Tasmanian and mainland Australian birds are not genetically differentiated. Some limited movement occurs between Tasmania and mainland Australia.

South Australia: Approximately 73 breeding pairs were recorded in recent surveys described in the recovery planning material.

Tasmania: Occurs across the coast and inland waterways, including major islands.

Distribution: Overseas range

Outside Australia, the species occurs from western India to southern China, across South-east Asia and New Guinea.

Distribution: Status and protection

The species is listed as Vulnerable in New South Wales and Tasmania, and Endangered in Victoria and South Australia. Western Australia uses Priority 4 for rare and near threatened species needing monitoring. South Australia and Tasmania also recognise near threatened equivalents under their respective legislation.

In Queensland, the species is protected wildlife. Interference with its breeding place may require a species management program. Confirm the current state and local requirements before site works.

Habitat: Water-associated habitat

Search for this species wherever large areas of open water occur near mature trees, cliffs or other secure nesting features. It can use both coastal and inland landscapes, but breeding pairs need suitable nesting habitat close to reliable foraging areas.

Relevant water bodies include the sea, bays, inlets, estuaries, lagoons, reefs, rivers, lakes, reservoirs, billabongs, freshwater swamps and dams.

Coastal habitat may include beaches, tidal flats, saltmarsh, mangroves, coastal dunes and rocky shores. Inland habitat may include riparian woodland, wetland margins, floodplains and open water surrounded by forest or woodland.

Habitat: Terrestrial settings

The species may occur over grassland, heathland, woodland, open forest, rainforest and swamp sclerophyll forest where these areas adjoin water or provide access to prey.

Convoluted coastlines, large estuaries and shorelines with undisturbed trees or cliffs are useful areas to inspect during a pre-clearing assessment.

Habitat: Site features to check

Inspect large emergent trees, dead branches, prominent perches, cliff ledges, rock stacks, mangrove stands and isolated trees near water. In Tasmania, most nest sites are within 5 km of the coast or a large estuary, although inland nests also occur along major rivers, lakes and dams.

For broad site assessments, include water bodies and adjoining habitat rather than assessing the proposed clearing footprint alone. Important feeding and flight areas may extend beyond the nest site.

  • Large trees with broad lateral branches.
  • Mature live or dead trees that stand above surrounding vegetation.
  • Cliffs, rock outcrops and shallow cave overhangs.
  • Mangrove forest, tidal creeks and wetland edges.
  • Open water with fish, waterbirds or other likely prey.

Foraging habitat: Food and hunting areas

White-bellied Sea-eagles hunt over water and land, usually from a perch or while soaring and gliding. Protecting prey habitat and access between nests, roosts and feeding areas is as important as protecting the nest tree.

The main foods are fish and freshwater turtles. Waterbirds, reptiles, small mammals and carrion are also taken.

Look for productive shorelines, shallow water, tidal creeks, wetland margins, fish nursery areas, river pools, reservoirs and floodplain water bodies. Saltmarsh, mangroves, seagrass and riparian vegetation can support prey populations.

Foraging habitat: Foraging behaviour

An eagle may circle slowly or sail along a shoreline about 10 to 20 m above the water. It may also still-hunt from a prominent perch, dive or glide to the water surface, or take prey from the ground.

Prey is usually carried to a feeding platform or perch. Small prey may be eaten in flight. Eagles may also steal prey from ospreys, terns and other birds.

  • Check prominent trees, snags, poles, rocks and branches beside water for feeding activity.
  • Record repeated low flights, prey carrying, attacks on prey and regular flight paths between water and nesting habitat.
  • Treat fish farms, fishing areas and locations with high fish or waterbird activity as potential foraging areas.

Foraging habitat: Construction considerations

Clearing or degrading mangroves, saltmarsh, seagrass, riparian vegetation and shallow water habitat can reduce prey availability. Pollution, sedimentation, altered water quality and loss of fish nursery habitat may affect birds even when the nest tree is retained.

Keep access routes, cranes, towers, wires, lighting and other tall structures under review where they may interrupt regular movements between a nest, guard roost and feeding area.

Breeding habitat: Nest sites

Breeding pairs defend a territory centred on a favoured nest site and may reuse the same nest for many years. Nesting birds are particularly sensitive to disturbance during courtship, nest repair, egg laying and early incubation.

In many areas, nests are in large emergent eucalypts or other mature trees near water. Suitable trees may have broad lateral branches, dead emergent limbs or a clear view over surrounding habitat.

Other nest sites include coastal cliffs, rock outcrops, shallow cave overhangs, mangrove forest, low coastal scrub and rock stacks. On predator-free islands, nests may be on the ground or on treeless coastal landforms.

  • Mature tall open forest.
  • Open forest and tall woodland.
  • Swamp sclerophyll forest.
  • Riparian floodplain forest.
  • Coastal cliffs, islands and remote rocky shorelines.

Breeding habitat: Nest structure and territory

Nests are large piles of sticks lined with leaves, grass, stems or seaweed. They may become very large through repeated repair and use.

A breeding territory can include the nest, guard roosts, feeding platforms, access routes and nearby foraging habitat. Nest guard roosts are within line of sight of the nest and may be up to 800 m away.

Clutch: Usually one or two eggs, commonly two.

Laying period: Generally June to September in the broader Australian guidance. South Australian laying is mostly in July and August.

Nestling period: Young remain in the nest for about 65 to 70 days.

Breeding habitat: Sensitive breeding periods

In South Australia, courtship, nest building and repair occur mainly in May and June. Egg laying and early incubation are especially sensitive, followed by incubation and early nestling care from late July to mid September.

Work near a nest can cause adults to desert eggs or small young. Older nestlings may leave prematurely if approached closely, so reduced sensitivity later in the season does not remove the need for a site-specific assessment.

  • Confirm whether a nest is active before clearing, blasting, piling, tree removal or high-noise work.
  • Avoid unnecessary approach to the nest, guard roost and likely flight path.
  • Use a fauna ecologist to set practical controls where a nest or breeding place is within the potential disturbance area.

Sheltering habitat: Roosts and guard trees

Shelter and resting places include prominent trees, dead branches, rocks and other structures beside water. These features may be used daily even when the nest itself is outside the works area.

Large dead trees and emergent branches near a nest are commonly used as guard roosts. They provide a view over the nest territory and may be used while adults watch the nest or wait between flights.

Other roosts include prominent trees, rocks and branches beside water. Eagles may roost in the morning and evening, and pairs may call together while perched.

Guard roost distance: Guard roosts may be up to 800 m from the nest.

  • Retain prominent live and dead trees beside waterways.
  • Inspect trees in line of sight of a nest, including trees outside the clearing footprint.
  • Record regularly used perches, feeding platforms and landing trees.

Sheltering habitat: Cover and resting habitat

The species does not depend on dense ground cover for shelter. It generally uses elevated, open perches with a clear view of water, prey areas and the nest territory.

Coastal cliffs, rock stacks, isolated trees, mangroves and mature riparian forest can provide secure resting or lookout locations.

Sheltering habitat: Site protection

Do not assume that retaining the nest tree is enough. Removing guard trees, blocking access to water, disturbing a regular perch or severing the flight path to a feeding area can still affect a breeding pair.

Where a nest or likely roost is identified, establish a clearly marked no-entry area for workers and machinery while the site-specific disturbance controls are confirmed.

Threats: Clearing and habitat loss

The main works-site risks are loss of nest trees, disturbance near breeding places and damage to waterways or prey habitat. The species may abandon a nest when exposed to repeated or poorly timed human activity.

Land clearing can remove nest trees, guard roosts, feeding platforms and riparian vegetation. It can also force birds into suboptimal nesting habitat where breeding success is lower.

Coastal subdivision, residential development, tourism infrastructure and development around estuaries can reduce both nesting habitat and access to prey.

  • Retain mature emergent trees, large dead trees and trees beside water.
  • Protect mangroves, saltmarsh, seagrass, riparian vegetation and shallow water habitat.
  • Assess the wider territory, not only the trees scheduled for removal.

Threats: Disturbance and nest abandonment

The species is sensitive to disturbance while nesting, particularly during courtship, nest repair, egg laying, incubation and early nestling care. People, vehicles, machinery and repeated site access can cause adults to leave the nest.

Activities associated with nest abandonment include residential and coastal development, off-road vehicle use, bushwalking, rock climbing, fishing, hunting, surfing and intrusive photography.

  • Plan high-noise or high-traffic work outside the most sensitive breeding period where practicable.
  • Keep workers, machinery, drones and visitors away from nests, guard roosts and approach routes.
  • Stop and seek ecological advice if adults show repeated alarm, circling, calling or prolonged absence from a nest.

Threats: Waterway and prey impacts

Clearing, reclamation, sedimentation, pollution and poor water quality can reduce fish and other prey. Over-fishing and deterioration of inland water sources can also reduce food availability.

Design drainage, erosion control, lighting and access arrangements to avoid degrading nearby waterways, wetlands, estuaries and fish nursery habitat.

Threats: Mortality and contamination

Discarded fishing line, hooks and fish farm nets can entangle or injure birds. Vertebrate pest control, agricultural pesticides, industrial chemicals and deliberate poisoning can cause mortality or reduce breeding success.

Keep chemicals, baits, waste and fishing materials secured and remove discarded line, netting and plastic from work areas and nearby waterways.

Survey methodology: 1. Desktop assessment

White-bellied Sea-eagles are large, conspicuous birds, but adults, juveniles and nests can be missed where waterways, cliffs or dense forest limit visibility. Use a combination of desktop review, targeted nest searches, vantage-point observations and follow-up checks, with greater effort for endangered populations and known breeding territories.

Map all waterways, estuaries, wetlands, coastlines, cliffs, large trees and potential feeding areas within and around the work area. Give particular attention to habitat within approximately 1 km of large waterbodies, which has been used as a focus for nest surveys.

Search state wildlife databases, local council records, previous ecological reports, landholder information and citizen-science records. Confirm whether the site is in or near a known nest territory, guard roost, feeding platform or flight path.

Treat records as indicative rather than proof of absence. Territories can include large areas, and nest locations may change within the core territory over time.

  • Record the relevant state or territory listing before fieldwork begins.
  • Check whether the work may affect a known breeding place, nest tree, guard roost, feeding platform, waterway or access route.
  • Map potential disturbance points, including roads, tracks, vantage points, machinery areas, blasting locations, boat routes and recreational access.

Survey methodology: 2. Targeted field survey

Search suitable nest trees, cliffs, rock stacks, low coastal scrub, mangroves and isolated trees near water. Look for large stick nests, nest repair, whitewash, prey remains, feathers, guard roosts and repeated adult activity.

Use quiet vantage points to watch adults carrying sticks or prey, attending a nest, displaying, calling, soaring repeatedly over one location or moving along a regular route. Inspect likely nest trees from the ground before approaching more closely.

Plan surveys when visibility is good and wind, rain, glare and heat do not prevent reliable observation. Avoid approaching a suspected nest to improve detection, as close observation can cause abandonment.

  • Survey from several vantage points where terrain, vegetation and access allow.
  • Repeat observations when a bird, nest, guard roost or flight path is detected but breeding status is uncertain.
  • Use binoculars or a telescope where available, and record the observer position and viewing conditions.
  • Increase survey effort for South Australian endangered populations, Victorian endangered populations, and sites supporting known or potential breeding territories.
  • In New South Wales and Tasmania, apply the same precaution at known or potential breeding sites because the species is vulnerable there.

Survey methodology: 3. Timing and survey effort

There is no established migration period that can be used to avoid detection. Survey timing should instead reflect local breeding activity and the proposed disturbance.

Breeding activity may occur from May to January, with laying commonly between July and August in South Australia, June to September in New South Wales, and June to January in Tasmania. The most sensitive period is generally courtship, nest building, laying and early incubation.

  • Complete an initial survey before finalising the work footprint and access routes.
  • Repeat surveys close to construction if the initial survey was undertaken outside the local breeding period, if conditions have changed, or if new nests or birds are reported.
  • Allow enough observation time to determine whether birds are repeatedly using a location. Set effort according to habitat visibility, project risk, the size of the search area and the conservation listing.
  • Do not rely on a single quiet observation to conclude that a nest or territory is unused.

Survey methodology: 4. Records and mapping

Record the location and type of every nest, suspected nest, guard roost, feeding platform, flight path and observation point. Keep sensitive nest locations restricted to people who need the information for protection and compliance.

Photograph habitat and structures from a distance where this can be done without causing disturbance.

  • Record date, start and finish time, weather, wind, visibility, tide or water conditions where relevant, observers and survey methods.
  • Record bird age class where possible, behaviour, direction of travel, food carried, calls, nest attendance and whether one or both adults were present.
  • Record whether the nest appears active, recently repaired, occupied, newly built or unused.
  • Map the proposed disturbance footprint and all activities that may be visible or audible from the nest or guard roost.
  • Document the basis for any conclusion that a site is suitable, unsuitable, occupied or inactive.

Before habitat disturbance: 1. Approvals and permits

Avoiding a nest or territory is the safest management option. Before work starts, confirm approvals, define no-go areas and brief every person who may enter the site, operate machinery or direct the work.

Confirm the legal status that applies in the project jurisdiction. The species is vulnerable in New South Wales and Tasmania, endangered in Victoria and South Australia, and an EVNT species for project planning. It is a protected marine species under the EPBC Act but is not listed as a threatened species under that Act.

Obtain state or territory approvals before disturbing a nest, breeding place, protected animal, habitat or vegetation. In Queensland, obtain or comply with the required species management program where work may tamper with a breeding place of a protected near threatened animal.

Consider whether the action requires an EPBC referral because of impacts to the species as a listed marine species or because other protected matters may be affected. Obtain advice from the relevant environmental regulator before work begins.

  • Keep copies of approvals, permits, conditions, maps and contact details on site.
  • Check whether a wildlife handler, fauna spotter catcher or other person must hold a specific state authorisation.
  • Do not assume that a general clearing approval authorises disturbance to an active nest or breeding place.
  • Escalate any proposed impact to a known endangered population or occupied territory to the project ecologist and relevant regulator.

Before habitat disturbance: 2. Avoidance and work design

Retain the nest tree, nearby guard roosts, mature trees, cliffs, rock stacks, large dead trees and the vegetation linking the nest to water and feeding areas. Retain access to the nest and unobstructed movement between the nest, roost and foraging habitat.

Use the smallest practical work footprint. Move laydown areas, roads, towers, cranes, lights, noisy equipment and worker access away from the core territory.

South Australian guidance identifies guard roosts and disturbance trigger sites commonly 500 to 800 m from nests. Use this as a prompt to investigate the wider territory, not as an automatic approval distance. Set a site-specific exclusion area with the ecologist and regulator.

  • Mark the nest, guard roost, feeding platform and exclusion area on plans and on the ground where this will not draw people towards the nest.
  • Keep people, vehicles, drones, boats and recreational activity out of the exclusion area unless specifically authorised.
  • Prevent new tracks, viewing points and public access near the nest.
  • Retain riparian, wetland, mangrove, saltmarsh, seagrass and shallow-water habitat that supports prey.
  • Use shielding and low-intensity lighting directed away from waterways, nest sites and flight paths.

Before habitat disturbance: 3. Timing and pre-clearance survey

Schedule clearing and high-noise work outside the local breeding period where practicable. If work must occur during breeding activity, redesign the work to avoid the nest and seek regulator and ecologist advice before proceeding.

Complete a pre-clearance inspection shortly before work starts. Recheck all potential nest trees, cliffs, rock stacks, guard roosts and nearby waterways because nests may be repaired or relocated within a territory.

  • Do not clear a nest tree, active nest, guard roost or breeding place until the approval pathway and site controls are confirmed.
  • Treat a nest as active if adults attend it, defend it, repair it, carry food or sticks to it, or if eggs or young are present.
  • Stop the pre-clearance inspection and escalate if an active nest, dependent young, injured bird or previously unrecorded territory is found.
  • Confirm that no proposed activity will block regular access to the nest, feeding platform or water.
  • Record the inspection and have the ecologist sign off the work area before mobilisation.

Before habitat disturbance: 4. Exclusion and induction

Fence or otherwise clearly mark no-go areas before machinery arrives. Use signs that identify the reason for the exclusion without publishing sensitive nest locations unnecessarily.

All workers, subcontractors, visitors, boat operators and fauna handlers must understand that approaching or harassing the birds can cause nest desertion.

  • Include photographs or maps of the nest, roost and exclusion area in the induction where appropriate.
  • Tell workers not to approach, photograph, feed, chase or fly drones near the birds.
  • Give the fauna spotter catcher and site supervisor authority to stop work immediately.
  • Set a communication chain for new sightings, nest activity, injured animals and breaches of controls.
  • Prohibit unapproved night work, bright lighting, blasting, rock climbing and recreational access near the territory.

During habitat disturbance: 1. Sequential clearing

Work slowly and in stages. The fauna spotter catcher or ecologist must be able to stop work whenever the activity creates an unexpected risk to a bird, nest, breeding place or flight path.

Clear only the approved footprint and retain all marked exclusion areas. Use staged clearing so that habitat edges, trees and structures can be checked before each new stage.

Keep machinery, people and stockpiled material away from nest trees, guard roosts and access routes to water. Avoid sudden increases in noise, dust, lighting and traffic.

  • Complete a daily pre-start check for bird activity and changes to the nest or roost.
  • Work from the least sensitive edge towards the approved footprint, unless the ecologist specifies another sequence.
  • Pause work if an adult repeatedly circles, calls, dives, carries food, approaches machinery or shows defensive behaviour.
  • Stop work if a bird is flushed from a nest or if a nest, roost or breeding place is discovered within the impact area.
  • Do not use drones or aircraft near an active territory without specific approval and a documented risk assessment.

During habitat disturbance: 2. Authority to stop work and handling

The fauna spotter catcher, project ecologist or authorised site supervisor must have clear authority to stop work. No worker should attempt to resolve a wildlife issue by moving closer or handling the bird.

White-bellied Sea-eagles are large raptors with powerful talons and beaks. Handling must be undertaken only by appropriately authorised and trained wildlife personnel.

  • Keep workers and machinery at a safe distance and establish a temporary exclusion area.
  • Do not touch eggs, young, nests or nesting material unless directed by the relevant regulator and an authorised wildlife professional.
  • Do not relocate a nest or bird as a routine mitigation measure.
  • Keep dogs, vehicles, boats and the public away from a grounded or injured bird.
  • Record the time, location, activity, bird behaviour and people involved in every stop-work event.

During habitat disturbance: 3. Active breeding places and roosts

If an active nest, eggs, young, breeding place, colony or roost is found, stop the affected work and protect the location. Colonies are not typical of this species, but any repeated communal roost or important gathering site should be treated cautiously until assessed.

Contact the project ecologist and relevant regulator or permit holder. Restart only when the response, exclusion area and work method have been approved.

  • Keep the original observer and crew away from the site unless their presence is required for safety.
  • Do not flush adults to confirm eggs or young.
  • Maintain the nest tree, guard roost, surrounding vegetation and flight access.
  • Review noise, vibration, lighting, access, blasting, clearing and work hours before deciding whether work can continue nearby.
  • Document the finding and any regulator direction as a formal environmental incident or permit event.

During habitat disturbance: 4. Injured or grounded birds

Treat a grounded, entangled or injured bird as a wildlife incident. Protect the bird from people, dogs, traffic and further disturbance while arranging professional assistance.

Fishing line, discarded netting and other debris can entangle sea-eagles. Do not pull material from a bird unless directed by an authorised wildlife carer or veterinarian.

  • Stop nearby work if it is contributing to the risk.
  • Contact the state wildlife authority, licensed wildlife rehabilitator or project fauna veterinarian through the approved emergency pathway.
  • Use a secure temporary exclusion area and keep the site quiet.
  • Do not provide food or water unless instructed by the attending wildlife professional.
  • Record photographs from a safe distance, the location, apparent injury, time found and the response taken.

After habitat disturbance: 1. Post-clearance checks

A site is not cleared of risk when vegetation removal ends. Check the remaining habitat, confirm that controls worked and follow up any bird, nest or disturbance incident.

Inspect the completed work area and retained habitat for damaged nests, displaced birds, entanglement hazards, exposed access routes and changes to water or feeding habitat.

Recheck known nests and guard roosts from a distant vantage point. Do not approach simply to obtain a closer view.

  • Complete checks after each clearing stage and after major changes in machinery, access or work methods.
  • Look for adult attendance, food delivery, calling, defensive behaviour, nest repair and dependent young.
  • Remove discarded line, netting, wire, plastic and other hazards from the work area.
  • Confirm that exclusion markers remain in place and that no unauthorised access has developed.
  • Record the condition of retained trees, cliffs, roosts, waterways and vegetation.

After habitat disturbance: 2. Monitoring and relocated animals

Where work occurred near a territory, set monitoring proportionate to the listing, the disturbance risk and the permit conditions. Endangered populations and known breeding territories need closer and longer follow-up than a low-risk site with no bird activity.

If an animal was captured or relocated by an authorised person, obtain the release location, condition, transport details and follow-up requirements.

  • Monitor nest attendance and breeding behaviour from a distant, repeatable vantage point.
  • Use the same observation points and recording method where practical so changes can be compared.
  • Confirm that relocated or rescued birds have been transferred to the approved wildlife professional or release program.
  • Do not assume that a bird flying away has survived or that a nest is unaffected.
  • Escalate reduced attendance, repeated alarm behaviour, nest abandonment or an injured bird immediately.

After habitat disturbance: 3. Reporting and incident review

Report permit breaches, nest disturbance, injury, mortality, unauthorised clearing and damage to a breeding place through the approval and regulator pathways. Keep records available for audits and future work stages.

Review incidents promptly. The aim is to change the work method before similar risk occurs again.

  • Prepare a completion report with survey dates, observers, maps, nest and roost records, exclusion controls, stop-work events and monitoring results.
  • Notify the relevant state or territory authority where required by the permit or legislation.
  • Record whether the incident involved noise, vegetation removal, lighting, access, machinery, fishing waste, chemical exposure or another cause.
  • Update the site environmental management plan, induction and map controls.
  • Retain sensitive nest information securely and share it only with people who need it for protection or compliance.

Rehabilitation actions: 1. Restore habitat and water

Rehabilitation should restore the food, water, cover and large structures used by the species. Protecting existing mature trees, cliffs, roosts and waterways is usually more reliable than trying to replace them after clearing.

Reinstate native vegetation around waterways, wetlands, estuaries and coastal habitat. Link retained trees and water to surrounding habitat where the project has fragmented access.

Protect water quality and prey habitat during earthworks and operation.

  • Stabilise disturbed banks and shorelines with locally appropriate native species.
  • Control sediment, contaminated runoff, fuel, chemicals and concrete washout.
  • Retain or restore riparian vegetation, mangroves, saltmarsh, seagrass and shallow-water habitat where these occur naturally.
  • Remove fishing line, netting, wire, plastic and other entanglement hazards.
  • Maintain fish and other prey habitat rather than relying on supplementary feeding.

Rehabilitation actions: 2. Retain and replace breeding structures carefully

Retain mature emergent eucalypts, large dead trees with suitable branches, cliffs, rock stacks and low coastal nesting habitat. Existing structures have greater value than replacement structures because pairs may use established territories for many years.

Artificial nest sites may suit this species in limited situations, but they require specialist design, a suitable territory, access to prey and approval from the relevant regulator.

  • Do not install a nest platform, artificial nest or replacement structure close to an active nest without specialist advice.
  • Assess line of sight, approach routes, tree or structure stability, flood and fire risk, human access and proximity to foraging habitat.
  • Use artificial structures only where monitoring and maintenance can be guaranteed.
  • Do not use nest boxes or bat boxes as substitutes for sea-eagle habitat. They are not appropriate replacement structures for this species.
  • Record whether the structure is used, repaired, occupied or abandoned, without approaching during sensitive breeding stages.

Rehabilitation actions: 3. Weeds, fire and access

Manage weeds and fuel loads without removing nest trees, guard roosts or cover used by prey. Works that alter vegetation structure or access can change the value of a territory even when the nest tree is retained.

Prevent new disturbance around restored habitat.

  • Use staged weed control outside sensitive breeding activity where practical.
  • Keep machinery and herbicide away from waterways, nest trees and retained dead trees.
  • Design fences, tracks and gates to prevent uncontrolled vehicle access to remote nesting areas.
  • Use signs and barriers to discourage recreation near nests and cliffs.
  • Review fire planning with the land manager so that burns do not remove nest trees, guard roosts or important riparian habitat.

Rehabilitation actions: 4. Lighting and long-term monitoring

Limit artificial lighting near waterways, nest sites and flight paths. Monitor restored areas for habitat condition, prey access, human disturbance and renewed entanglement hazards.

Use a monitoring period and success measures that match the approval conditions and the conservation listing.

  • Shield lights and direct them away from water, cliffs, trees and retained habitat.
  • Use the lowest practical intensity and avoid unnecessary night lighting.
  • Inspect restored habitat after floods, storms, fire and major maintenance works.
  • Monitor existing and replacement nest structures from distant vantage points during the local breeding season.
  • Review management if birds stop using a territory, show repeated disturbance behaviour, or if water quality and prey habitat decline.
