Buceros rhinoceros

- Rentan
National bird of Malaysia. Its upturned orange-and-red casque amplifies duet calls across Borneo rainforest.
- Populasi
- Population size not quantified; overall trend decreasing (forest-loss modeling suggests ~35-40% decline over three generations/42 years, with hunting pressure likely pushing actual decline higher)
- Habitat
- Primary lowland and hill tropical rainforest, extending into tall secondary forest, from sea level up to about 1,400 m elevation; occasionally forages in disturbed forest edge and plantations but depends on large tracts of intact forest for nesting
- Fakta menarik
- During nesting the female seals herself inside the tree-cavity nest with mud, food, and feces, leaving only a narrow slit through which the male passes food until the chick is ready to fledge; once the chick is fully feathered, the dried mud barrier is broken down.
