Description: Slender tyrannid 18–19 cm long, highly aerial, recalling a swallow in flight silhouette and hunting style. Upperparts brown with darker wing edges; rump and base of the tail rufous-cinnamon, ending in black. Underparts cinnamon (more intense in the NE). In flight, shows extensive rufous on wings and tail, visible even at a distance. Crown somewhat triangular; bill thin and straight; legs short. In western areas it may be confused with the Streak-throated Bush-Tyrant (Myiotheretes striaticollis), but the Cliff Flycatcher is smaller, more slender and much more agile in flight, with more uniform plumage and a throat without heavy streaking. The Cinnamon Flycatcher (Pyrrhomyias cinnamomeus) is much smaller and plumper, has olive upperparts, a concealed yellow crown, and is restricted to the Yungas.

Geographic distribution: Widespread in South America, from the Guianas and Venezuela to NE and NW Argentina between 350–4000 m, where two subspecies occur: Pallidior (West / Andean-Montane): NW Argentina (Jujuy, Salta, Tucumán, Catamarca); continues into La Rioja, San Juan and Mendoza, and east into the sierras of Córdoba and San Luis. Mainly resident, with altitudinal movements. Associated with ravines, montane scrub, dry yungas and rocky upland habitats. Paler, with softer ventral tones. Bellicosa (NE): only in spring and summer. Misiones and Corrientes, occasionally farther south along the Argentine littoral (current records in Buenos Aires). Also in Uruguay. Occurs in forest edges, towns and wooded open areas. More reddish on the belly, more rufous-brown above, and generally brighter plumage.

Habitat: Montane forests and woodlands, yunga ecotones, scrub, forest edges, cliffs, high ravines and rocky outcrops. Highly adaptable, also in urban zones, tall buildings, wires and bridges.

Behavior: Very aerial; spends much time flying or sallying from high perches. Solitary or in pairs; occasional family groups. Active hunter, with strong aerial sallies and long pursuits. In ravine zones of NW Argentina it commonly coexists with the White-winged Black-Tyrant (Knipolegus aterrimus). Vocal at heights: strong, prolonged whistles, sharper in the NW and deeper, more drawled in the NE.

Diet: Arthropods captured by elastic, prolonged and highly agile sallies, returning to the same perch. Hunts like a swallow: long forays from rocky walls, exposed branches, wires and buildings. Occasionally captures small arthropods on rocky surfaces.

Reproduction: Open cup nest built on rocky ledges, road cuts, high shelves, bridges, buildings and vertical structures. Materials: dry grasses, moss, feathers and small twigs; sometimes small stones used as filler. Clutch: 2–3 eggs, white with cinnamon or brown speckles.

Conservation status: Not threatened. Tolerant of modified environments and broadly distributed, especially in central and western regions.
