Who's Who
on the Mudflats

The migratory and resident shorebird species a Steward needs to recognise, understand, and document. A name is just a label. What each species needs, why it is here, and what threatens it is a different body of knowledge — and that is what this program delivers.

Already Gone

Eight shorebird species are confirmed extinct. These are not future losses. They are past ones. The dates below are the last time a living individual was recorded. After that date — nothing. A different species appears each time this page is opened.

Fewer Than 500

One species. One living population. Fewer than 500 individuals on the planet. What follows — the Critically Endangered, the Endangered, the Vulnerable — is what the road before this point looks like. This is the road's end.

VulnerableEPBC Act · NSW Endangered · SA Vulnerable
Rare vagrantMoreton Bay — southern edge of range
Why this species is in trouble
🏖️

Beach recreation pressure — no escape

The Hooded Plover's nesting territory is the same strip of beach used by people, dogs, horses, and vehicles. Eggs incubate in a shallow scrape just above the high tide line for 28 days. The nest is invisible to anyone not looking for it. A single disturbance event during incubation on a warm day can raise egg temperature past the point of viability within minutes.

🦊

Predation — foxes, ravens and Silver Gulls

Introduced foxes are the primary predator of eggs and chicks on southern beaches. Silver Gulls — whose populations have expanded enormously in association with human food waste — take eggs and newly-hatched chicks with regularity. Corvids add further pressure. The nesting pair has no structural defence against any of these: the nest is open ground.

📉

Low recruitment — too few chicks survive

In the eastern population, chick survival to fledging is consistently poor. Monitoring in NSW and Victoria has shown breeding seasons where no chicks survived on surveyed beaches. The adult birds are long-lived and pair-faithful — which can mask the absence of recruitment until the population is already in sharp decline.

🟢 What a Steward does about this

At Moreton Bay, where the Hooded Plover is at the northern edge of its range and occurrence is rare, any confirmed sighting during the breeding season (August–January) is immediately worth recording and reporting to BirdLife Australia's Shorebird Recovery Program. The FID for a bird on an active nest is extremely short — approach within 30 metres risks nest desertion.

Why this species is in trouble
🌏

Yellow Sea staging loss — same bottleneck

The Asian Dowitcher stages on Yellow Sea tidal flats on the northbound migration, using the same sites as Bar-tailed Godwit, Far Eastern Curlew and Great Knot. The same reclamation that is driving those species into decline is working on this one — with less documentation and less international attention, partly because the species is harder to survey and partly because its wintering grounds in Myanmar and Bangladesh are less well-monitored than Australian sites.

🎣

Hunting on wintering grounds

On wintering grounds in Myanmar, Bangladesh and India, shorebird trapping continues despite bilateral agreements. The Asian Dowitcher's larger size relative to stints and sandpipers makes it a more conspicuous target. Conservation work in these countries — engaging local communities in protection — mirrors the approach being used for the Spoon-billed Sandpiper and is beginning to show results.

🔍

Poor baseline data — hard to count, easy to miss

Population estimates for the Asian Dowitcher carry wide uncertainty. The species is genuinely rare, but it is also easily overlooked in mixed godwit and curlew assemblages at distance. Every confirmed count at a site like Moreton Bay adds to a dataset that is thin in Australia. A Steward who identifies one is not just making a record for their own log — they are contributing to the global picture.

🟢 What a Steward does about this

Any Asian Dowitcher sighting at Moreton Bay should be recorded in Shoreline Watch with full details: species, count, associated species, GPS, tidal state, date and time. It should also be reported directly to QWSG. The feeding action — rapid vertical probing, straight bill driven deep into soft mud — is the key field distinction from Bar-tailed Godwit, which probes at a shallower angle. Leg colour (dark grey-black) and bill base (dark, not pink) confirm identification.

The species and what to look for
〰️

The bob — constant, compulsive, diagnostic

The tail-bobbing action of the Common Sandpiper is not occasional or contextual. It is continuous — the bird bobs as it feeds, bobs as it stands, bobs as it watches you. No other sandpiper in the Moreton Bay assemblage bobs in this way with this frequency. Combined with the stiff, bowed-wing flight low over water — alternating rapid wingbeats with short glides — the species is identifiable at distance before the field marks are visible.

🏔️

A different habitat niche

The Common Sandpiper works the edges that the mudflat specialists ignore: rocky shore margins, mangrove roots, seawall base, jetty pilings, the margins of freshwater drains where they meet tidal water. It is rarely on open mudflat. At Moreton Bay sites it is most often found singly at the structural edges of the site — the places a Steward passes through rather than stands at. Worth a deliberate look on every visit.

🌐

Context — why it belongs here

The Common Sandpiper breeds across temperate and boreal Eurasia from Britain to Kamchatka and migrates along multiple flyways to Africa, India and Australasia. Its presence at Moreton Bay is a reminder that the EAAF is not the only flyway operating simultaneously. This individual bird may have flown from Siberia or Central Asia. Least Concern today; it uses the same Yellow Sea and Southeast Asian stopovers as species that are not.

🟢 What a Steward does about this

Recording Common Sandpiper presence — site, count (usually one), habitat (rocky margin, seawall, mangrove edge), date and tidal state — adds to the broader species inventory for each Moreton Bay site. Its solitary habit means it is genuinely undercounted in shorebird surveys focused on open mudflat. A Shoreline Watch entry for a single Common Sandpiper at a jetty base is a real data point.

The species — and its place at Moreton Bay
👁️

Cryptic by design, ancient by lineage

The Bush Stone-curlew is not a shorebird in the strict sense, but it is a Charadriiform — related by deep evolutionary descent to the waders and plovers it occasionally shares habitat with. Its enormous yellow eyes are adapted for nocturnal hunting: insects, lizards, crabs and invertebrates taken in the dark from the ground. By day it freezes, elongates its neck, and tilts its bill slightly upward — a posture that breaks its silhouette and renders it nearly invisible against any background it chooses to stand against. This is not learned behaviour. It is millions of years old.

🦊

Southern range collapse — fox predation

In Queensland, the Bush Stone-curlew remains common in urban parks, foreshores and coastal woodland. Its range once extended across most of southern Australia. That has contracted by approximately 90%, driven primarily by red fox predation of eggs, chicks and sitting adults. The species nests on bare ground — a simple scrape — with no structural protection. In the south, where fox populations are dense, breeding success has been near zero for decades in many areas.

🌙

At Moreton Bay — presence and pressure

Common in urban parks and foreshore areas around Moreton Bay — Centenary Lakes Cairns to the north, Brisbane parklands, Minjerribah — the Bush Stone-curlew is under localised pressure from dogs and vehicle traffic. Nest sites are unprotected. Pairs are site-faithful and will attempt to nest year after year in the same location. A pair nesting at a regularly disturbed site has almost no breeding success.

🟢 What a Steward does about this

Bush Stone-curlews at Moreton Bay shorebird sites are worth recording — their presence documents habitat quality for a broader suite of species than the migratory shorebirds alone. If a pair is known to nest at a site, noting nest location, access routes, and disturbance events builds a case for local management intervention. The species responds poorly to dog disturbance at the nest — the adult sits tight and then abandons, often within a short disturbance window.

The species and its habitat
💧

A freshwater specialist at a saltwater site

The Black-fronted Dotterel occupies the freshwater and low-salinity margins of coastal wetlands — the places where a stormwater drain meets an estuary, where a shallow pool forms behind the mangrove fringe, where a small creek crosses the intertidal zone. It feeds by sight, running and pausing to pick invertebrates from the surface and shallow water. It does not probe. It does not wade into depth. It works the margins that the mudflat species walk past.

🪺

Ground-nesting at the water's edge

Nests are a simple scrape lined with plant material, placed on bare ground or gravel near water. Like the Hooded Plover and the Red-capped Plover, the Black-fronted Dotterel relies on cryptic coloured eggs and an incubating adult that sits very tight. Predation by cats and foxes is the primary threat to nesting success. Wetland drainage eliminates habitat entirely — this species has no alternative to freshwater-adjacent ground.

🔍

Overlooked in shorebird surveys

Standard shorebird monitoring at Moreton Bay roost sites focuses on open intertidal mudflat at high tide — the Black-fronted Dotterel is almost never there. It occurs at the freshwater edges of the same sites, or at nearby wetland margins that are not counted in QWSG roost surveys. Recording it extends the species inventory of a site and documents habitat quality for a broader assemblage.

🟢 What a Steward does about this

At Moreton Bay sites that include freshwater wetland margins — Hays Inlet, Tinchi Tamba, parts of Toondah — the Black-fronted Dotterel is worth a deliberate scan of the freshwater edges before and after the main mudflat survey. Recording its presence, count and location builds a more complete picture of site ecological character than mudflat-only counts provide.

The species at Moreton Bay
🦵

Extraordinarily long legs — a functional adaptation

The Pied Stilt's legs are proportionally the longest of any Australian bird relative to body size. They allow it to wade into water far deeper than any godwit or curlew can reach, picking invertebrates from the water column and from soft sediment in depths that exclude every other wader at the site. At Moreton Bay it uses open mudflat, shallow channels, saltmarsh pools and freshwater wetlands — a generalist that occupies the full vertical range of the intertidal zone.

📢

The alarm caller — ecological function

The Pied Stilt's loud, persistent alarm call when disturbed — a high repeated yapping — functions as an alert for every other species at a mixed roost. At Kakadu Beach and Toorbul, if stilts flush, godwits and curlews look up. Recording whether stilts were alarmed before a roost disturbance event adds context to the record that the flush of migratory species cannot provide on its own.

🥚

Ground-nesting at intertidal margins

The Pied Stilt nests on bare ground close to water — often a simple scrape on a saltmarsh bank or a small rise in the intertidal zone. Nests are vulnerable to tidal wash-over at king tides, to fox and cat predation, and to trampling. The adults are aggressive in nest defence, dive-bombing approach from considerable distance, but cannot prevent physical disturbance of the eggs.

🟢 What a Steward does about this

The Pied Stilt is the canary of a mixed roost. Recording its alarm state — feeding quietly, standing alert, flushed and calling — before and after a disturbance event gives the roost monitoring record a behavioural baseline that flock count alone does not provide. A flush of Pied Stilts 10 minutes before a godwit roost disperses tells you something about the disturbance sequence.

The species and how it feeds
〽️

The upcurved bill — a sweeping instrument

The bill of the Red-necked Avocet curves upward, unlike the downward curve of the curlews and godwits or the straight probing bills of the stints. It is a sweeping bill — moved rapidly side-to-side through shallow water just at the surface, detecting invertebrates by touch. The bird walks steadily forward, sweeping as it goes, feeding in a manner no other shorebird at Moreton Bay uses. Like the Spoon-billed Sandpiper on this page, the bill shape defines the ecological niche and the feeding technique simultaneously.

🗺️

Nomadic ecology — following water across a continent

The Red-necked Avocet is not migratory in the EAAF sense — it does not breed in the Arctic and winter in Australia. It breeds inland when rainfall creates suitable wetlands, and moves to coastal sites when inland conditions dry. Its presence at Moreton Bay is therefore variable and hard to predict. Numbers can shift dramatically between seasons. Recording it — including flock size and site location — contributes to understanding of its population distribution across the coast.

🌊

Shallow water specialist — habitat dependency

The avocet needs shallow, open water — saltpan, estuarine lagoon, tidal flat at the right depth. Too deep and the sweep-feeding cannot reach the bottom. Too exposed at low tide and the sediment dries out. At Moreton Bay it uses the shallow margins of tidal flats and constructed wetlands — including, occasionally, the artificial lagoon at the Kakadu Beach constructed roost where water depth is managed.

🟢 What a Steward does about this

Red-necked Avocet presence at Moreton Bay sites is always worth recording with flock size and site location. Its sweep-feeding technique is immediately distinguishable from every other species on the flat — a Steward who spots the side-to-side bill action has made an identification without needing to see the chestnut head. Reporting large flocks to QWSG contributes to coastal distribution monitoring for a species whose total numbers and seasonal movements are not precisely known.

🏊

A wetland specialist — not a mudflat bird

The Red-kneed Dotterel occupies shallow freshwater wetlands, flooded grasslands, saltmarsh edges and estuarine margins with emergent vegetation. It feeds by running across exposed mud and shallow water, picking invertebrates by sight — the same run-and-pause technique as other plovers, but at wetland edges rather than open intertidal flat. At Moreton Bay it uses the inland wetland fringes of sites that extend beyond the tidal zone: Tinchi Tamba, Hays Inlet, the freshwater margins behind mangrove fringe.

🔴

The name and the field mark

The red knee joint — a splash of reddish-orange at the leg joint visible when the bird is stationary — gives this species its name. In the field it is not always obvious, particularly when the bird is moving. The more reliable field marks are the combination of black hood with white throat (no other Australian dotterel has this combination), and the chestnut-brown flanks visible in flight. The bill is short, straight and black. Legs are greenish-grey.

🪺

Ground-nesting at wetland margins

Nests on bare ground or shallow scrape at wetland edges, often concealed in sparse vegetation. Eggs are cryptically marked. Both parents incubate. Cat and fox predation, wetland drainage and water level manipulation all affect breeding success. The species is adaptable to modified wetlands — rice paddies, sewage treatment ponds, constructed wetlands — but requires some fringe vegetation and stable water levels during the breeding period.

🟢 What a Steward does about this

Recording Red-kneed Dotterel at Moreton Bay sites extends the species inventory beyond the mudflat assemblage and documents the freshwater component of site ecological character. It is often present at the same sites as Black-fronted Dotterel — both can occur at the freshwater margins that a mudflat-only survey misses. Noting habitat type (freshwater pool, saltmarsh edge, mangrove fringe drain) adds value to any record.

The conservation response that followed is one of the most intensive in shorebird history.
The species — and where we are
🥄

The bill — unique in nature

The spatulate bill of Calidris pygmaea has no equivalent among living birds. It sweeps side-to-side through shallow water and mud, detecting invertebrates by touch and by the pressure changes its distinctive tip creates. This bill shape evolved over millions of years. It is shared by no other wader, no other shorebird family, nothing. When this species goes, the bill goes with it — an irreplaceable evolutionary solution to a problem that will never be solved again in the same way.

The Spoon-billed Sandpiper breeds on coastal tundra in Chukotka and the Bering Sea region of northeast Siberia. Its migration takes it south through the Yellow Sea, the Chinese coast, and into Myanmar, Bangladesh and Thailand for the non-breeding season. It uses the same staging sites, the same tidal flats, and faces the same reclamation and hunting pressure as the Far Eastern Curlew, the Great Knot, and the Bar-tailed Godwit on this page. The difference is that it arrived at the edge of extinction first, and in smaller numbers. There were never many of them. The margin for error was always smaller.

🏛️

The ark at Slimbridge — and what it took to build it

In November 2011, thirteen Spoon-billed Sandpipers arrived at the Wildfowl and Wetlands Trust reserve at Slimbridge, Gloucestershire — hatched from eggs collected in remote northeast Russian tundra, quarantined for 60 days at Moscow Zoo, and flown 8,000 km to the UK. A second expedition in 2012 added 17 more. The purpose was unambiguous: a captive ark as last resort against extinction. For eight years, the flock laid eggs that failed to hatch. What finally worked was artificial day-length simulation — recreating the photoperiod changes the birds experience on their wild migration, from Arctic summer to Asian winter. In 2019, two chicks hatched and were raised to adulthood. The first Spoon-billed Sandpipers ever bred in captivity. By 2024, the Conservation Breeding Project had concluded its formal phase — two males remain at Slimbridge, their care generating knowledge for future programs. The Russia-Ukraine conflict paused headstarting operations at the Chukotka breeding grounds, though expeditions continued. Preparations for a 2025 restart were underway.

🌱

Headstarting — buying time while the flyway is fixed

Parallel to the captive program, a headstarting technique has been running in Russia: eggs are taken from wild nests early in the season, artificially incubated under controlled conditions, and chicks released into the wild shortly after fledging. In the wild, only 3 in every 20 chicks survive to adulthood. Headstarted: 15 in 20. The technique has stabilised what had been a decline of up to 25% annually. It buys time. The permanent solution — protecting the staging and wintering habitat on which the entire flyway depends — remains incomplete.

🟢 What a Steward understands about this

Every species on this page shares staging and wintering habitat with the Spoon-billed Sandpiper. The tidal flat at Kakadu Beach that receives Bar-tailed Godwits from Alaska is part of the same ecological chain that the Spoon-billed Sandpiper depends on further north. When a Steward records a disturbance event, monitors roost condition, or builds the evidence base for a site management decision, they are contributing to the health of a flyway that extends from this beach to Arctic Siberia — and that the Spoon-billed Sandpiper tells us, clearly and without ambiguity, is already failing in places.

What has already happened

Eight shorebird species are confirmed extinct. On 10 October 2025, the IUCN officially declared the Slender-billed Curlew (Numenius tenuirostris) extinct — the first recorded global bird extinction from mainland Europe, North Africa, and West Asia. Last confirmed sighting: Merja Zerga, Morocco, February 1995. The treaty established to protect it was finalised four months after the last photograph was taken.

All eight extinct species are documented in the Already Gone section at the top of this page. Each one is a record, not a warning. These events are finished. The Spoon-billed Sandpiper's situation is not.

Why this species is in trouble
🌏

Yellow Sea tidal flat loss — 65% gone

The northbound staging habitat has been reclaimed for industry and agriculture. Without adequate refuelling here, birds arrive at Alaskan breeding grounds underweight and fail to breed.

🥚

Breeding failure cascade

Underweight birds produce fewer chicks. Fewer fledglings reach Moreton Bay each September. Every poor Yellow Sea season compounds the next.

Disturbance at pre-departure

March–April at Moreton Bay: birds are rebuilding fat reserves for the northbound flight. A single roost flush costs 4+ hours of foraging time that cannot be recovered during this critical window.

🟢 What a Steward does about this

Every disturbance event recorded in the Shoreline Watch during March–April builds the evidence base for protective management at Kakadu Beach and Toorbul. Your field records are the argument for signage, for seasonal access restrictions, for council engagement.

🌏

Yellow Sea habitat — 65% gone

More dependent on Yellow Sea mudflats than almost any other flyway species. As staging habitat disappears, the population has nowhere to go. The dependency is almost total.

🦀

Specialised feeding — no alternatives

Feeds on deep-burrowing crabs and yabbies in mud channels. Cannot substitute sandy beaches or rocky shores. As mudflat quality drops, so does the food available at both staging and non-breeding sites.

High disturbance sensitivity

Feeds singly or in very small groups on exposed mud. Extremely sensitive to human approach at any distance. Any disturbance event involving this species at Moreton Bay should be documented immediately.

🟢 What a Steward does about this

Far Eastern Curlew disturbance events carry the highest weighted score in the RMTools. One documented event creates a data point with direct management implications — for protective signage, fencing decisions, and formal council engagement.

Single-bottleneck staging dependency

The entire flyway population passes through Yellow Sea tidal flats on the northbound migration. There is no alternative route. As flats disappear, there is nowhere else to refuel.

❄️

Arctic breeding disruption

Climate change is disrupting lemming cycles on the breeding tundra. Lemming populations regulate predator pressure on nesting shorebirds. Without the cycle, breeding success becomes unpredictable year to year.

📉

Compound population collapse

Staging habitat loss and breeding disruption are hitting simultaneously. The 80% decline in 30 years reflects both working together — a compound collapse with no single fix.

🟢 What a Steward does about this

Counting Curlew Sandpipers within Red-necked Stint flocks at Moreton Bay contributes to flyway-wide population monitoring. The Shoreline Watch records counts by species — your observations from Kakadu Beach or Toorbul feed directly into the QWSG dataset.

🟢 What a Steward does about this

Moreton Bay is identified critical non-breeding habitat for this subspecies. Confirming presence, counting numbers, and documenting disturbance events adds to the evidence base for site-level protection. Your records matter at the subspecies level, not just the site level.

Flyway staging habitat loss

High-altitude and arid-zone breeding

Breeds in arid and semi-arid zones across Central Asia and the Middle East. Breeding habitat quality is affected by climate change and increasing agricultural pressure. Pressure on both ends of the flyway is compounding.

🟢 What a Steward does about this

Distinguishing Greater from Lesser Sand Plover in the field — using bill length and depth as the primary feature, supported by head profile and leg colour — is one of the more demanding identification challenges in the Moreton Bay shorebird assemblage.

The bird, and why it matters
🔍

Hidden in plain sight

In non-breeding plumage — which is what you see at Moreton Bay — the Broad-billed Sandpiper is grey-brown above and white below. It stands in the densest part of a Red-necked Stint flock, slightly hunched, slightly shorter-legged, feeding slowly. The field mark is the split supercilium: a forked white eyebrow stripe, unlike any other wader on the flat. You can stand at Kakadu Beach and look directly at one without knowing it. The bird that rewards attention. The one that will not come to you.

🌏

Same flyway. Same pressure. Same mud.

The sibirica subspecies breeds in taiga bogs across central and eastern Siberia, then moves south along the East Asian–Australasian Flyway to spend the non-breeding season on coastal mudflats across Southeast Asia and Australia. It passes through or stages on the same Yellow Sea tidal flats as the godwit and the curlew sandpiper. The same reclamation that is dismantling those species' populations is working on this one too — more quietly, with less documentation, but just as steadily.

📉

A quiet decline becoming visible

The Broad-billed Sandpiper was assessed as Least Concern for decades — partly because it is hard to count, and partly because nobody was looking closely enough. The 2021 uplisting to Vulnerable reflected what the data had been suggesting for some time: a decline exceeding 30% over three generations, driven by the same staging habitat loss affecting every species in this assemblage. The difference is that the godwit had someone watching. This bird mostly did not.

🟢 What a Steward does about this

Identifying a Broad-billed Sandpiper in a mixed flock at Moreton Bay — distinguishing it from the Red-necked Stints surrounding it by bill shape and the forked supercilium — is a meaningful field accomplishment. Recording it in the Shoreline Watch by species rather than noting it as "stints" is a data contribution. This species is under-recorded at Moreton Bay, partly because it is hard to see and partly because identifying it requires deliberate attention. A Steward who learns it is doing something most people at the foreshore will never do.

Why this species is in trouble

Beach recreation and dog disturbance

Nests on open beaches and reef platforms year-round. Nesting attempts are extremely sensitive to pedestrian and dog disturbance. A single disturbance can cause nest abandonment.

📅

Slow reproduction

Typically raises only one chick per year in undisturbed conditions. Low reproductive rate means disturbance-caused failures have a disproportionate impact on local population stability.

🟢 What a Steward does about this

The Beach Stone-curlew's response to disturbance is one of the clearest demonstrations of what a Steward's presence can achieve. Recording nesting activity and disturbance events at beach sites builds the case for formal dog-restriction zones and seasonal access management.
