Dryoscopus is a genus ofbird in theMalaconotidae or bushshrike family. Its members are known aspuffbacks. The six species, all of fairly uniform appearance and habits, arenative to various parts ofsub-Saharan Africa.[2] The nameDryoscopus is a compoundGreek word:drus from the Greek word for "tree" andskopos, meaning "watcher or lookout".[3]
Puffbacks are small, active bushshrikes that show a superficial resemblance toboubous. They however display only rudimentary duetting, have red or reddish irides, are smaller and compact with bouncy flight, and displaysexual dimorphism.[4] Characteristically, the long, loose and pale feathers of the male bird's back and rump are puffed out conspicuously during display. At the same time he may fly about, calling loudly.[5] Comparable habits are found in some related genera (cf.Bocagia,Bias,Lanioturdus,Batis andDyaphorophyia).[6]

They move about in pairs in the upper strata of trees (Pringle's excepting) and may join mixed-species flocks.[5] They command a varied repertoire of explosive and fricative whistles, percussive clicking sounds, and harsh rasping, churring or tearing sounds.[6] Three species have a raspingalarm call (cubla,senegalensis andpringlii), while the remaining three (gambensis,angolensis andsabini) have a stuttering alarm call. Wing fripping and bill snapping complement vocal communication. The nest is a neat compact cup in the general fashion of bushshrikes, but similar to those of shrike-flycatchers.Courtship feeding is present, and studied species are monogamous and single-brooded.
DNA-DNA hybridization studies suggest that genusTchagra is their closest relative, though biological traits also link them toLaniarius, shrike-flycatchers (i.e.Bias andMegabyas) and other genera.[6]
The genus contains the following six species:[7]
| Image | Common name | Scientific name | Habitat | Distribution |

| Pink-footed puffback | Dryoscopus angolensis | isolated montane and submontane forests | Kenya, Uganda and the easternCongo Basin | |
| Black-backed puffback | Dryoscopus cubla | tropical to austral woodlands and afromontane forest | sub-Saharan Africa, from southern Somalia to coastal South Africa. | |
| Northern puffback | Dryoscopus gambensis | equatorial to sub-Saharan wooded savannah | northern sub-Saharan Africa | |
| Pringle's puffback | Dryoscopus pringlii | dry, equatorial acacia scrub and thicket | Ethiopia, Kenya, Somalia, and northern Tanzania | |
| Sabine's puffback | Dryoscopus sabini | tropical forest | Congo basin and West African coast | |
| Red-eyed puffback | Dryoscopus senegalensis | mid-canopy at tropical forest edge and clearings[4] | Nigeria and Central Africa. |
