||150 cm. Large, black ratite. Adult all black except bright blue and red neck, with small blue or red single wattle. Chicks are striped then become plain brown, paler than other forest gamebirds. Similar spp. The upland Dwarf Cassowary C. bennetti is smaller, with a low casque and no wattle. The parapatric Southern Cassowary C. casuarius has a higher casque and double wattle. Voice Booming and grunting similar to other cassowaries. Hints Rarely seen, its presence is usually indicated by its large piles of droppings containing fruit stones, or by its large, three-toed footprints.

This species is classified as Vulnerable on the basis of an estimated small, declining population. However, there are few data and, although this species is generally scarce, it is often shy. Basic research may lead to reclassification.

|Range Description:||Casuarius unappendiculatus is restricted to the northern lowlands of New Guinea (Papua, formerly Irian Jaya, Indonesia, and Papua New Guinea). Its distribution on the Vogelkop is poorly known, but it is known from Yapen, Batanta and Salawati islands (Coates 1985, Eastwood 1996, B. Beehler in litt. 2000). There are few records as this region is seldom visited. There are recent records from Batanta, Salawati and Waigeo in north-west Papua, but several other surveys in Papua have failed to find it (Eastwood 1996, K. D. Bishop in litt. 1999, Mack and Alonso 2000). It is usually less common where hunted (K. D. Bishop in litt. 1999), but large areas of its range are remote with few hunters and it is suspected to be fairly common in the foothills of the Foja Mountains of western New Guinea (B. Beehler in litt. 2012). Beyond these scattered records, there are no data on population or trends.|

|Population:||The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
Trend Justification: It is suspected to be declining at a moderately rapid rate, owing to hunting pressure and increasing habitat loss and pressures from an expanding human population.
