The Brolga (Grus rubicunda) is an Australian bird that can be identified most reliably by combining shape, plumage, habitat and behaviour. A very tall grey crane with long legs, a long neck, bare red skin on the back and sides of the head and a dark dewlap under the chin. Adults are typically about 100–140 cm long, although sex, age and posture can affect how large an individual appears in the field.
How to identify a Brolga
A very tall grey crane with long legs, a long neck, bare red skin on the back and sides of the head and a dark dewlap under the chin. Start with the overall silhouette before focusing on colour. Check the bill, legs, tail, wing shape and any bold head or body pattern. Distance, shade and strong Australian sunlight can change the apparent colour of feathers, so several matching features are more useful than a single mark.
Famous for elaborate pair and group dances involving bows, leaps and wing displays. Birds often occur in pairs or flocks outside breeding season. 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 Brolga found in Australia?
Northern and eastern Australia, with important populations on tropical floodplains and in parts of Queensland, New South Wales and Victoria.
Typical habitat includes shallow wetlands, floodplains, wet grasslands, crop fields and open plains close to water. Distribution can shift with rainfall, drought, breeding conditions, migration and local food supply, so an apparently unusual sighting should be checked against season as well as location.
What does the Brolga eat?
Tubers, seeds, grain, insects, frogs and other small animals, often dug or picked from wet ground. Watching exactly how a bird feeds can provide another useful clue. Note whether it walks, probes, dives, sweeps its bill, hunts from a perch 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 plants is usually a better way to support them than regular feeding.
Behaviour and calls
Famous for elaborate pair and group dances involving bows, leaps and wing displays. Birds often occur in pairs or flocks outside breeding season.
Loud, far-carrying trumpeting calls, often given in duet by paired birds. Voice is particularly useful when vegetation, distance 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
A large platform nest is built in shallow water or marsh vegetation; both adults guard the nest and chicks. Breeding timing varies around Australia according to latitude, rainfall and local conditions. If you find a nest or dependent young, observe from a respectful distance and avoid changing the adults’ normal approach route.
Similar birds
Sarus Crane is extremely rare in Australia and has more extensive red on the head and upper neck; Black-necked Stork has black-and-white plumage and a heavy bill.
When two species remain difficult to separate, compare photographs against multiple field marks rather than choosing on colour alone. Geographic range, voice and habitat may be more decisive than one feather pattern.
Quick identification tip
Remember three things: its approximate size is 100–140 cm; its key visual clue is a very tall grey crane with long legs, a long neck, bare red skin on the back and sides of the head and a dark dewlap under the chin.; and a typical setting is shallow wetlands, floodplains, wet grasslands, crop fields and open plains close to water. Matching all three gives a much stronger identification than any one clue by itself.
