The black bee-eater (Merops gularis) is a striking bird in the family Meropidae, characterized by its vibrant and contrasting coloration. Measuring approximately 20 cm (8 in) in length, this predominantly black bird boasts a vivid scarlet chin and throat. Its breаst is streaked, adding to its distinctive appearance. Additional features include a pale blue eyebrow, blue belly, undertail-coverts, rumρ, and rufous primaries, creating a colorful and easily recognizable bird.

The black bee-eater is native to the tropical rainforests of Sub-Saharan Africa. It thrives primarily at the edges of these rainforests and in secondary woodland areas, showing a preference for habitats where it can find abundant insect prey.

There are two recognized subspecies of the black bee-eater, each with subtle differences:

1. **M. g. gularis**: This subspecies ranges from Sierra Leone to southeast Nigeria. It is noted for its blue forehead and a bright cobalt-blue superciliary stripe. Birds found in southeast Nigeria and western Cameroon often show intermediate characteristics between this subspecies and M. g. australis.

2. **M. g. australis**: Found from southeast Nigeria to northeast Democratic Republic of the Congo and south to northern Angola, this subspecies lacks the superciliary stripe seen in M. g. gularis. Its forehead is generally black, occasionally featuring a few blue feathers. The light azure-blue streaks on the breаst and belly sometimes have scarlet tips. Additionally, M. g. australis has slightly longer wings than the nominate subspecies.

The black bee-eater is classified as “Least Concern” by the International Union for Conservation of Nature (IUCN). Despite the lack of a precise population estimate, the species is widespread and common within its extensive range. Its stable population and adaptability to various habitats within the rainforest contribute to its favorable conservation status.
