Arremon crassirostris
The Sooty-faced Finch (Arremon crassirostris) is a strikingly marked, medium-sized songbird, typically measuring around 16 cm (6.3 inches) in length and weighing 26-34 grams. Its distinctive appearance includes a thick, dark bill, a sooty-gray head that gives the species its common name, and a vibrant olive-green back and wings. A prominent white throat starkly contrasts with a broad black band across its chest, which then gives way to a clean white belly, and its legs are typically pinkish. ...
This species primarily inhabits the dense undergrowth of humid montane forests, cloud forest edges, and mature secondary growth. It is typically found at elevations ranging from 800 to 2000 meters (2,600-6,500 feet) above sea level.
Its diet consists primarily of insects and other small invertebrates, including beetles, ants, and larvae, which it gleans from foliage and ground litter. Seeds and small fruits also form a significant part of its diet, especially seasonally.
The Sooty-faced Finch is a rather secretive and largely terrestrial bird, spending much of its time foraging on or near the ground within the dense understory. It exhibits diurnal activity, with peak foraging efforts often occurring during the early morning and late afternoon hours, retreating in...
