Monachella muelleriana
The Torrent Flyrobin, *Monachella muelleriana*, is a small to medium-sized passerine, typically measuring 13-15 cm (5.1-5.9 in) in length and weighing around 12-18 g (0.4-0.6 oz). Its upperparts are uniformly dark sooty-grey to blackish, contrasting sharply with clean white underparts, a key identification feature. A distinctive broad white band across the lower back and rump is often visible in flight or when the bird is perched. The face is dark, sometimes with a faint pale eye-ring, and it...
Confined to the immediate vicinity of fast-flowing montane and foothill streams, rivers, and torrents within primary rainforests and adjacent disturbed areas. Typically found at elevations ranging from 300 to 2,300 meters (1,000 to 7,500 feet) above sea level.
Primarily insectivorous, feeding on a wide variety of flying insects (e.g., mayflies, caddisflies, midges) caught in flight, as well as aquatic insect larvae and occasional small fish. Foraging method is predominantly aerial hawking from low perches over water.
Torrent Flyrobins are diurnal and highly active, often perching prominently on rocks, logs, or branches directly over or immediately adjacent to rushing water. They are specialized aerial insectivores, employing a distinctive 'sally-strike' foraging technique where they launch from a perch to sna...
