Tiivisia

Tiivisia is a genus of small, ground-dwelling birds belonging to the family Cettiidae. These birds are typically found in dense undergrowth and scrubby vegetation across parts of Asia. Their appearance is generally drab, with olive-brown plumage, often lighter on the underside. They possess a relatively long tail which they tend to flick upwards, a characteristic behavior that can aid in their identification.

The genus Tiivisia is known for its secretive nature, making them challenging to observe. They are primarily insectivores, foraging on the ground for insects, spiders, and other small invertebrates. Their song is often described as a series of rapid, high-pitched notes or a trill, though it can vary between species.

Currently, the genus Tiivisia includes a limited number of recognized species, though taxonomic classifications can sometimes be subject to revision based on genetic and morphological studies. Like other members of the Cettiidae family, Tiivisia species are adapted to their specific habitats, often inhabiting riparian zones, bamboo thickets, and dense forest undergrowth. Their distribution spans various regions of Asia, with some species having more localized ranges than others.
