Rufous-necked Hornbill

The Rufous-necked Hornbill, <em>Aceros nipalensis</em>, is a large and striking member of the family Bucerotidae, found across a discontinuous range in the eastern Himalayas, parts of northeastern India, and into Southeast Asia including Myanmar, Thailand, Laos, Vietnam, and southern China. It inhabits dense tropical and subtropical forests, typically at mid-elevations, where large fruiting trees and old-growth forest structure are essential for its survival. Detailed plumage and bill descriptions are not fully captured in the data available here, though hornbills in this genus are generally characterized by impressive casques and bold coloration. The species is a cavity nester, with the female sealed inside a natural tree hollow during incubation and early chick-rearing, a strategy typical of hornbills. Clutch size is small, ranging from 1 to 2 eggs. The Rufous-necked Hornbill is currently assessed as Vulnerable, reflecting significant population declines driven by habitat loss due to deforestation and hunting pressure. Its dependence on large old-growth trees for nesting makes it particularly sensitive to forest degradation and fragmentation across its range.
