Pachyglossa agilis
The Thick-billed Flowerpecker, *Dicaeum agile*, is a diminutive and often overlooked passerine belonging to the Dicaeidae family, renowned for its specialized diet and crucial role in seed dispersal. Measuring approximately 8-10 cm in length with a weight of 6-9 grams, it exhibits a rather drab plumage of olive-brown upperparts and paler, grayish-white underparts, lacking any prominent markings or bright colors. Its most distinctive field mark is its relatively stout, short, and slightly hook...
This species primarily inhabits a variety of lowland to submontane tropical and subtropical broadleaf forests, woodlands, and secondary growth. It can also be found in plantations, orchards, and mature gardens, typically from sea level up to elevations of around 1800 meters.
The diet of the Thick-billed Flowerpecker consists predominantly of fruits, particularly the sticky berries of mistletoe species, as well as nectar. It also supplements its diet with small insects and spiders, which are gleaned from foliage and bark.
Active throughout the day, the Thick-billed Flowerpecker is often observed singly or in pairs, flitting rapidly through the canopy and subcanopy. Its foraging strategy involves agile movements as it gleans insects, sips nectar, and, most notably, consumes fruits, especially mistletoe berries. Whi...
The Thick-billed Flowerpecker boasts a wide and largely contiguous breeding and resident range across the Indian subcontinent and Southeast Asia. Its distribution extends from the lower Himalayan foothills, encompassing much of India, Sri Lanka, Bangladesh, and Nepal, eastward through Myanmar, Th...
Least Concern
- The Thick-billed Flowerpecker is a crucial disperser of mistletoe seeds; without such birds, mistletoe plants would struggle to spread. - Its digestive system is highly specialized, allowing mistletoe berries to pass through quickly, often within 10-30 minutes, to minimize exposure to the toxic...
