White-fronted Nunbird is a fairly uncommon resident in the midstory and subcanopy of terre firme forest. The closely related Black-fronted Nunbird lacks the white face and is found in varzea forest rather than terre firme. Although their song is similar to Black-fronted, it is generally faster and higher; they also tend to be less vocal overall. Often encountered in pairs or small family groups, White-fronted Nunbirds are frequently found in mixed passerine flocks. In fact, seeing this species is often a good indication of a nearby flock.
