- Populasi
- Unquantified; widespread and locally common in suitable habitat, with a decreasing population trend attributed to habitat loss — no numeric global population figure published
- Habitat
- Coastal and riverine forest, forest edge, and lightly wooded savanna/woodland with thicker forest patches; also occurs in open fields and enters urban gardens near forest patches
- Fakta menarik
- Males and females look similar overall, but the male has a noticeably larger, redder casque atop the bill than the female (whose casque is smaller and bill base yellower) — one of the clearest visual ways to sex this species in the field.
