The black-billed wood hoopoe (Phoeniculus somaliensis) is a species of bird in the family Phoeniculidae.

The black-billed wood hoopoe is very similar to the green wood hoopoe (Phoeniculus purpureus) in appearance, but lacks the greenish gloss on the head and mantle and has a black beak rather than a red one, though there is sometimes a reddish tinge at the base of the beak.

[2][3] The black-billed wood hoopoe feeds on arthropods, millipedes, beetles and other invertebrates, foraging on trunks and branches by creeping along the bark, sometimes upside-down, and probing into crevices.

[4] The black-billed wood hoopoe is a common bird and has a very wide range.

Its population trend has not been quantified but it may be decreasing because the large trees in which it nests are becoming more scarce as a result of being harvested.
