Least Concern

Sassi's Olive Greenbul (Phyllastrephus lorenzi)


French: Bulbul de Lorenz German: Lorenzbülbül Spanish: Bulbul de Lorenz
Other common names: Sassi's Greenbul

Phyllastrephus lorenzi


, 1914,

Moera, near Beni, eastern DRCongo


Relationship with P. icterinus requires further analysis; the two are almost entirely sympatric, closely similar in structure, overlap in dimensions, and appear also to intergrade in crown colour; possibility of lorenzi being an acromelanistic form of that species has been considered in detail#R, but molecular evidence#R appears to validate its status as a species. Monotypic.


Scattered localities in NE & E DRCongo; one record from extreme W Uganda (Bwamba).
