The Black-collared Barbet is called a Rooikop-houtkapper in Afrikaans which acknowledges two characteristics of this common forest resident:
1. it has a red head, and
2. it uses its formidable bill to chop holes in dead trees to form a nest.
The nest is excavated to a depth of 15 to 25 cm into the vertical trunk of a tree by both sexes. The sound of their hammering at a dead tree usually leads birdwatchers to their nest-building activity.
