Description
The bicolored antvireo (Dysithamnus occidentalis) is an insectivorous bird in the antbird family Thamnophilidae. It is found on the west slope of the Andes from southwest Colombia to northwest Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. The bicolored antvireo was described by the American ornithologist Frank Chapman in 1923 who considered it a subspecies of the white-shouldered antshrike (Thamnophilus aethiops) and coined the trinomial name Thamnophilus aethiops occidentalis. There are two subspecies: D. o. occidentalis (Chapman, 1923) – southwest Colombia and north Ecuador D. o. punctitectus Chapman, 1924 – east Ecuador

Feeding Habits
Bicolored Antvireo feeds mainly on insects and other arthropods, such as caterpillars, moths, katydids, mantids, and crickets. It forages alone or in pairs, perch-gleaning from leaves and twigs near the ground, or sally-gleaning with short flights. Occasionally, bicolored Antvireo flips leaves on the ground to uncover prey.
Habitat
The bicolored Antvireo flourishes predominantly in the understory layers of montane evergreen forests, particularly in areas where sunlight filters more heavily through the canopy, such as natural clearings, landslides, and light gaps. Its environment is characterized by a dense assortment of woody and herbaceous vegetation, with a notable presence of small-diameter trunks and stems, as well as a floor rich in leaf litter. Ferns, small plants, and occasionally bamboo typify the ground flora within these vibrant habitats.
