Sungrebe

The sungrebe is now the only species placed in the genus Heliornis that was erected by the French naturalist Pierre Bonnaterre in 1791 with the sungrebe as the type species. The name of the genus combines the Ancient Greek hēlios meaning "sun" and ornis meaning "bird". The specific epithet fulica is Latin for "coot".

These waterfowl have broad lobes on their feet, convergent to that of grebes or coots, that they use to propel themselves in the water. They are reclusive birds, preferring well-covered slow-flowing streams and secluded waterways, sometimes swimming partly submerged, like an anhinga.

Sungrebes are unique among birds in that males have "pouches", folds of skin under their wings in which they carry their young from hatching until the chicks are able to swim for themselves. This has led to them being called "Marsupial Birds"; certain feathers, with their own musculature, serve as "guard rails" to prevent the baby from falling out.
