Cnipodectes subbrunneus
The Brownish Twistwing (Cnipodectes subbrunneus) is a small, cryptically plumaged flycatcher of the Tyrannidae family, notable more for its unique wing structure and the mechanical sounds it produces than its modest appearance. Measuring approximately 14-16 cm (5.5-6.3 inches) in length and weighing 17-21 grams, adults exhibit a dull olive-brown back, a rufous-brown wash on the underparts, and a pale throat, often accented by a faint pale eye-ring. Its most distinctive field mark, though not ...
Resides in the humid tropical lowland and foothill evergreen forests, primarily frequenting the dense understory and forest edges, typically at elevations below 1200 meters. Often found near watercourses or in secondary growth, favoring areas with dense vine tangles and brush.
Primarily insectivorous, feeding on a variety of small to medium-sized arthropods. Forages by sallying from a low perch to snatch insects in mid-air or gleaning them directly from leaves and branches.
The Brownish Twistwing is a largely solitary and inconspicuous species, often remaining perfectly still for extended periods on shaded perches within the dense understory. Its foraging strategy involves short, quick sallying flights from a perch to snatch insects from the air (flycatching) or gle...
The Brownish Twistwing exhibits a notably disjunct distribution across Central and South America, occurring in two main, widely separated populations. The northern population is found on the Caribbean slope of Costa Rica and both slopes of Panama, extending south along the Pacific slope of wester...
