Pnoepyga formosana
The Taiwan Cupwing (Pnoepyga formosana) is a diminutive and enigmatic passerine, a true gem for dedicated birders exploring Taiwan's montane forests. Measuring a mere 8-9 cm in length with a weight of 10-15 grams, this tiny bird is characterized by its exceptionally short, almost vestigial tail, stout legs, and a remarkably plump, rounded body, giving it a distinctive 'ball-like' appearance. Its plumage is predominantly dark olive-brown, often exhibiting fine scaling or mottling on the crown ...
This species primarily inhabits dense undergrowth within montane broadleaf and mixed forests, particularly favoring areas with abundant moss, ferns, and bamboo thickets, typically found at elevations ranging from 1,000 to 2,800 meters above sea level.
Its diet consists almost exclusively of small invertebrates, including insects, spiders, and their larvae, which it primarily gleans from the forest floor, leaf litter, moss, and rotten wood.
The Taiwan Cupwing is a highly terrestrial and exceptionally skulking bird, spending nearly all its time foraging on the forest floor, often hidden deep within dense vegetation. It moves with a characteristic hopping gait, meticulously searching through leaf litter, moss, and decaying wood for in...
The Taiwan Cupwing is strictly endemic to the island of Taiwan, where it is distributed across the central mountain range. Its breeding range encompasses these higher elevation forests, typically found between 1,000 and 2,800 meters, occasionally venturing lower to around 500 meters in certain pr...
