The Russet-crowned Crake (Rufirallus xenopterus) is a critically endangered and highly localized rail found only in a small region of Paraguay and Brazil. It is characterized by its russet crown and duller body plumage.
Where to spot
Endemic to a very small region of eastern Paraguay and adjacent southwestern Brazil. Inhabits dense, seasonally flooded grasslands and marshy edges of gallery forests.
How to spot
Observation is extremely challenging due to its rarity and dense habitat. Focus on listening for its unique calls in its specific grassland habitat. Requires significant patience, local knowledge, and possibly specialized equipment.
When to spot
Year-round resident, but exceptionally difficult to find. Best chances might be during specific times of year when water levels make certain areas accessible or when they are more vocal.

This crake is one of the rarest and most threatened rails in the world, primarily due to habitat loss from agricultural expansion in its extremely limited range.
