Approval covers this version’s narrative, facts, quick answers and recorded locations in both languages. ## Quick answer The southern cassowary (*Casuarius casuarius*) is a bird in the family Casuariidae. Range in Indonesia: Parts of Indonesian Papua, plus Aru and Seram; human introductions complicate the origin of some island populations. Diet: fallen fruit; a herbivore. IUCN Red List status: Least Concern. It is a legally protected species in Indonesia (Regulation P.106/2018). | Fact | Value | |---|---| | Scientific name | *Casuarius casuarius* | | Indonesian name | Kasuari gelambir ganda | | Group | Birds | | Family | Casuariidae | | Range in Indonesia | Parts of Indonesian Papua, plus Aru and Seram; human introductions complicate the origin of some island populations | | Linked habitats | [Tropical Rainforests](https://panduanhewan.org/en/habitats/tropical-rainforest/) | | Adult feature | Two neck wattles | | Main food | Fallen fruit | | Parental care | Male incubates and cares for chicks | | IUCN status | Least Concern · [IUCN Red List (via GBIF)](https://www.gbif.org/species/5231783) · checked 1 October 2026 | | Legal protection in Indonesia | Protected · [Regulation P.106/2018](https://jdih.kehutanan.go.id/new2/uploads/files/P_106_2018_JENIS_TSL_menlhk_07252019152513.pdf) · annex no. 280 | | Size | 150–200 cm · [Australian Museum — Southern Cassowary](https://australian.museum/learn/animals/birds/southern-cassowary/) | | Population | 20,000–49,999 mature individuals globally (2016 estimate); about 4,000 birds in Australia · [BirdLife International DataZone — Southern Cassowary species factsheet](https://datazone.birdlife.org/species/factsheet/southern-cassowary-casuarius-casuarius) | | Clutch size | Clutch of 4 eggs, incubated by the male · [Australian Museum — Southern Cassowary](https://australian.museum/learn/animals/birds/southern-cassowary/) | | Diet type | Herbivore (plant-eater) — mainly fallen fruit (frugivore); occasionally small animals and fungi · [Animal Diversity Web](https://animaldiversity.org/accounts/Casuarius_casuarius/) | | Reproduction | Laying eggs (oviparous) · [Animal Diversity Web](https://animaldiversity.org/accounts/Casuarius_casuarius/) | | Active | Diurnal (active by day) — Can be active at any time, but forages by day and rests around midday. · [Pangau-Adam et al. 2015, Human impacts on two endemic cassowary species in Indonesian New Guinea, Oryx (Cambridge Core)](https://www.cambridge.org/core/journals/oryx/article/human-impacts-on-two-endemic-cassowary-species-in-indonesian-new-guinea/875900063705C9003574BB9AC63170A6) | ## Distinguishing cassowary species Adult southern cassowaries have black bodies, a casque on the head, and two red wattles. Chicks have different colours and patterns. The word cassowary covers several species, so identification cannot rely only on a large body and running ability. Evidence: [Cornell Lab eBird — Southern cassowary](https://ebird.org/species/soucas1) ## Fallen fruit connects birds and trees Fallen fruit is the main food, though cassowaries also eat other items. Swallowed seeds can be carried elsewhere. Their seed-dispersal role helps explain why losing a large bird can affect plant regeneration, beyond changing a forest’s animal list. Evidence: [Queensland Government — Southern cassowary ecology](https://www.qld.gov.au/environment/plants-animals/conservation/threatened-species/featured-projects/southern-cassowary) ## Males care for the next generation In this species, males incubate eggs and care for chicks after the female has laid. An adult accompanying young is not automatically their mother. Give family groups space and never separate chicks for photographs or because you assume they need rescue. Evidence: [Australian Museum — Southern cassowary biology](https://australian.museum/learn/animals/birds/southern-cassowary/) ## Australian forest research has limits Queensland explains cassowary seed dispersal and habitat needs, but Australian legal categories and numbers do not describe Papua. Green and colleagues (2022) also caution that human movements complicate the origins of Aru and Seram populations. A location record therefore does not automatically establish a native, unintroduced population.

Do not feed, chase, or block their way out. Follow site-manager guidance and observe from a safe distance; familiarity with people does not remove their need for space or natural behaviour.
