The Dusky Chlorospingus (Chlorospingus semifuscus) is a charming, medium-sized passerine, typically measuring around 13-14 cm (5.1-5.5 inches) in length and weighing about 17-21 grams (0.6-0.7 oz). Its plumage is characterized by dusky olive-green upperparts, contrasting with paler, yellowish-olive underparts and a conspicuous pale throat. A key identifying field mark is its relatively plain face, lacking the bold patterns found in some other chlorospingus species, hence "dusky" – it has a ra...
This species primarily inhabits humid montane forests and cloud forest edges, favoring dense undergrowth. It is typically found at elevations ranging from 1,000 to 2,500 meters (3,300-8,200 feet).
Its diet primarily consists of insects and other small arthropods, which it gleans from foliage and branches. It also occasionally consumes small fruits and berries, especially during times of insect scarcity.
The Dusky Chlorospingus is an active, diurnal bird, often observed foraging low in the understory or mid-story, rarely ascending to the canopy. It employs a gleaning foraging strategy, meticulously searching for insects and arthropods among leaves and twigs, sometimes making short aerial sallies ...
The Dusky Chlorospingus has a relatively restricted but stable distribution across the humid montane forests of the northern and central Andes. Its primary range extends from southwestern Colombia, southward through Ecuador, and into extreme northwestern Peru. In Colombia, it is found along the W...
