The dusky broadbill (Corydon sumatranus) is a species of bird in the family Eurylaimidae, the broadbills. It is native to Southeast Asia. It may be slowly declining due to habitat loss, especially from logging, but it has a large enough range that it is still considered to be a least-concern species. This species, like most in its family, is an insectivore. Wikipedia →
