The black-collared bulbul (Neolestes torquatus), or black-collared greenbul, is a species of songbird in the bulbul family, Pycnonotidae. It is monotypic within the genus Neolestes. For many years, some authorities considered the genus to belong to the bushshrike or shrike families due to shape and plumage similarities until a review of molecular genetic relationships in 1999 confirmed the behavioral and morphological affinities to Pycnonotidae. The black-collared bulbul is found in equatorial Africa in its natural habitat of dry savanna. Originally misclassified due to its external similarity to bushshrikes (Malaconotidae) or true shrikes (Laniidae), molecular studies in the late 1990s confirmed its rightful place in the bulbul family (Pycnonotidae). This finding highlighted the importance of genetic data in ornithology, as plumage and body shape alone can be misleading due to convergent evolution—when unrelated species evolve similar traits independently. The black-collared bulbul is omnivorous, feeding primarily on insects, spiders, and other small invertebrates, but it also consumes fruits and berries when available. This flexible diet allows it to thrive in the seasonally arid savannas of central Africa. The species is found across parts of equatorial Africa, including countries such as Gabon, Republic of the Congo, Democratic Republic of Congo, Cameroon, and Central African Republic. Its preferred habitat includes dry savannas, open woodland, and forest edges, where it forages among shrubs and low trees. Being the sole member of the genus Neolestes, the black-collared bulbul represents a distinct evolutionary lineage within the bulbul family. This monotypic status underscores its unique genetic and morphological characteristics, and may warrant special conservation focus as it embodies a separate branch of evolutionary history not shared with other bulbuls.
