Aphanotriccus audax
The Black-billed Flycatcher (*Aphanotriccus audax*) is a subtly marked, small passerine endemic to Colombia, belonging to the Tyrannidae family, characteristic of New World flycatchers. Measuring approximately 13-14 cm (5.1-5.5 inches) in length, this species sports a rather subdued plumage of olive-greenish upperparts, a dull whitish throat transitioning to pale yellow on the belly, and faint yellowish wing-bars. Its most distinguishing feature, and the origin of its common name, is its enti...
This species primarily inhabits the understory and mid-story of humid lowland and foothill forests, particularly near watercourses, and extends into dense secondary growth and forest edges, typically at elevations ranging from 100 to 1200 meters.
Predominantly insectivorous, the Black-billed Flycatcher feeds on a variety of flying insects such as flies, small beetles, and wasps, which it captures primarily through aerial sallies and gleaning from foliage.
The Black-billed Flycatcher typically forages in a classic "sit-and-wait" fashion, perching quietly on an exposed branch within the forest understory or mid-canopy, constantly scanning its surroundings for insect prey. Once an insect is spotted, it sallies out in a quick, often acrobatic flight t...
The Black-billed Flycatcher is strictly endemic to Colombia, with its range primarily confined to the humid lowlands and foothills of the Magdalena Valley, extending into the western slopes of the Central Andes and the eastern slopes of the Western Andes. This restricted distribution spans depart...
Vulnerable
- The Black-billed Flycatcher is so elusive that it was known from fewer than 20 specimens for much of the 20th century, making it one of the most poorly known Neotropical flycatchers. - Its entirely black bill is a key diagnostic feature, distinguishing it from many similar flycatchers that ofte...
