The Eastern Curlew (Numenius madagascariensis) is an Australian bird or regular visitor that can be identified most reliably by combining shape, plumage, habitat and behaviour. Australia’s largest shorebird, with long bluish-grey legs, streaked brown plumage and an extremely long downcurved bill that is especially long in females. Adults are typically about 60–66 cm long, although posture, sex, age and plumage can affect how large an individual appears in the field.

How to identify a Eastern Curlew

Australia’s largest shorebird, with long bluish-grey legs, streaked brown plumage and an extremely long downcurved bill that is especially long in females. Start with overall silhouette before focusing on colour. Check the bill, legs, tail, wing shape and any bold head or body pattern. Distance, shade, glare and strong Australian sunlight can change the apparent colour of feathers, so several matching features are more useful than a single mark.

Eastern Curlews walk methodically across exposed mud, probing deeply into burrows and soft sediment. They often fly between feeding grounds and high-tide roosts in loose lines. Behaviour can be one of the quickest ways to confirm an identification because closely related birds often feed, fly or perch differently even when their plumage looks similar.

Where is the Eastern Curlew found in Australia?

A migratory shorebird found around much of the Australian coast, with major concentrations in northern and eastern estuaries.

Typical habitat includes large tidal mudflats, estuaries, mangrove-lined creeks, sandflats and sheltered coastal roosts. Distribution can shift with rainfall, drought, breeding conditions, migration, tides and local food supply, so an apparently unusual sighting should be checked against season as well as location.

What does the Eastern Curlew eat?

Crabs, marine worms, molluscs and other deep-burrowing intertidal animals reached with the exceptionally long bill. Watching exactly how a bird feeds can provide another useful clue. Note whether it runs and pecks, probes mud, sweeps its bill, plunge-dives, surface-dips or catches food in flight. Feeding technique often separates species that share the same habitat.

Wild birds do not need processed human food. Protecting natural habitat, clean water and native food sources is usually a better way to support them than regular feeding.

Behaviour and calls

Eastern Curlews walk methodically across exposed mud, probing deeply into burrows and soft sediment. They often fly between feeding grounds and high-tide roosts in loose lines.

The call is a clear, far-carrying curlew whistle, often repeated in a rising series. Voice can be especially useful when distance, a crowded flock or low light makes visual identification difficult. Try to notice the rhythm and tone as well as a written approximation of the sound.

Nesting and breeding

Breeding occurs in north-eastern Asia; Australia is a major non-breeding destination for the species. Breeding timing varies according to latitude, climate and species. Many migratory shorebirds seen in Australia breed in the Northern Hemisphere, while resident terns and seabirds may nest on Australian beaches or offshore islands. If you find a nest or dependent young, observe from a respectful distance.

Similar birds

Whimbrels are smaller with a much shorter bill and a strongly striped crown, while godwits have straighter or slightly upturned bills.

When two species remain difficult to separate, compare photographs against multiple field marks rather than choosing on colour alone. Geographic range, voice, habitat and feeding style may be more decisive than one feather pattern.

Quick identification tip

Remember three things: its approximate size is 60–66 cm; its key visual clue is australia’s largest shorebird, with long bluish-grey legs, streaked brown plumage and an extremely long downcurved bill that is especially long in females.; and a typical setting is large tidal mudflats, estuaries, mangrove-lined creeks, sandflats and sheltered coastal roosts. Matching all three gives a much stronger identification than any one clue by itself.

When and where to look

The best chance of seeing the Eastern Curlew depends on the species’ movements and habitat. In Australia, start with large tidal mudflats, estuaries, mangrove-lined creeks, sandflats and sheltered coastal roosts. Early morning and late afternoon can provide calmer conditions and better light, while tidal shorebirds are easiest to study when falling water exposes feeding areas. For pelagic species, location, season and sea conditions matter more than time of day.
