Ravisca
Ravisca is a genus of small, ground-dwelling birds belonging to the family Muscicapidae, commonly known as Old World flycatchers. These birds are found in the forests and woodlands of Asia, with their distribution extending from the Indian subcontinent to Southeast Asia. Ravisca species are characterized by their relatively small size, often measuring around 10-15 centimeters in length. They typically possess plumage that is subdued and camouflaged, with males and females often exhibiting sexual dimorphism in their coloration. Their diet primarily consists of insects, which they catch by sallying out from a perch. The genus name Ravisca is derived from Latin, with "ravis" meaning hoarse and "scare" meaning to frighten or startle, possibly referring to their calls or behavior. They are generally solitary or found in pairs, and their nests are typically cup-shaped, constructed from moss, twigs, and other vegetation, and placed in trees or shrubs. While some species within the Ravisca genus are widespread and common, others may have more restricted ranges or be considered rare, facing potential threats from habitat loss and degradation. Further research is ongoing to fully understand the taxonomy and conservation status of various Ravisca species.
