They are not true ant-followers but are frequently observed foraging as part of mixed-species flocks, particularly with other insectivorous passerines. Foraging involves ...
The Black Antshrike is a resident species found exclusively in the humid montane forests of northwestern South America, primarily along the eastern slopes of the Andes. Its breeding and year-round range extends from the central Andes of Colombia, through eastern Ecuador, and south into northern P...
