The Masked Finfoot, *Heliopais personatus*, is an exceptionally elusive and striking aquatic bird, the sole representative of the Finfoot family (Heliornithidae) in Asia. Measuring approximately 48-56 cm (19-22 inches) in length and weighing around 500-800 grams, it boasts dark olive-brown upperparts, a stark white belly, and distinctive bright yellow lobed feet, which are unique adaptations for propulsion in water without being fully webbed. Males are particularly notable for their prominent...
This finfoot primarily inhabits dense, well-vegetated forested wetlands, slow-moving rivers, streams, and freshwater swamps, typically at low to moderate elevations up to 1000 meters.
Its diet consists mainly of aquatic insects, their larvae, crustaceans, mollusks, small fish, and occasionally amphibians, foraging by gleaning, dipping, and diving in freshwater environments.

It is an adept swimmer, gliding low in the water, frequently submerging its body and even its head, often hiding among overhanging vegetation or submerged roots. F...
