Rhizothera longirostris
The Long-billed Partridge (Rhizothera longirostris) is a distinctive medium-sized gamebird endemic to Southeast Asia, immediately recognizable by its remarkably elongated, decurved bill, which can measure up to 6.5 cm, giving it a unique profile among partridges. Adult males typically weigh around 600-750g and measure 30-37 cm in length, featuring a striking rufous-chestnut cap, greyish underparts, and an olive-brown back, often with fine barring, while females are slightly smaller and duller...
Found primarily in dense primary and secondary lowland evergreen rainforests, extending into lower montane forests, typically up to 1,500 meters in elevation, favoring areas with thick undergrowth and bamboo. It also adapts to disturbed forests and dense thickets.
Feeds predominantly on a variety of invertebrates, including insects, grubs, worms, and mollusks, complemented by seeds and fallen fruits, primarily obtained by probing the forest floor with its specialized bill.
The Long-billed Partridge is a shy and largely terrestrial species, typically active during dawn and dusk, foraging solitarily or in small coveys of 2-5 individuals. Its unique long bill is used to probe deeply into leaf litter and soft soil for subterranean invertebrates, a foraging strategy rar...
