B. bicolor, commonly known as the Bicolor Damselfish, is a small, vibrant fish found in the Indo-Pacific region. It is distinguished by its striking two-toned coloration—typically a dark anterior and a lighter posterior. This species inhabits coral reefs, where it plays a role in maintaining the health and balance of the reef ecosystem.

B. bicolor, commonly known as the Bicolored Antbird, is native to Central and South America. Its geographical distribution includes countries like Panama, Colombia, Venezuela, Ecuador, Peru, Bolivia, and Brazil. The species is predominantly found in lowland forests and foothills.

The Bicolored Antbird inhabits tropical and subtropical moist lowland forests. These environments are characterized by high humidity, dense vegetation, and a warm climate with minimal temperature variation throughout the year. The species is often associated with primary forests but can also be found in secondary growth and edge habitats.

B. bicolor is typically found in the understory of forests where it participates in mixed-species flocks. It is known for following army ant swarms to feed on insects and other small arthropods disturbed by the ants, a behavior common among antbirds. This ecological niche requires the bird to be adept at navigating dense foliage and quick to respond to the movements of ant swarms.
