This genus is still a mystery to scientists
This genus was previously classified as a member of the Capitonidae family and also the Ramphastidae family!
The hairy-breasted barbet (Tricholaema hirsute) was named after the genus Tricholaema by the French brothers Jules and Édouard Verreaux in 1855. The generic name is derived from the Ancient Greek words thrix, which means “hair,” and laimos, which means “throat.”
Many members of this genus have unknown nesting habits, yet some social species may nest on riverbanks or termite nests, which is unusual among the Piciformes. Like many other Piciformes, their nests are dug into trees, and they usually lay two to four eggs (except for the yellow-breasted barbet, which lays up to six), which are incubated for 13–15 days. Both parents share the responsibility of nesting.
