Maroon-chinned Fruit Dove

The maroon-chinned fruit dove of Sulawesi is currently named Ramphiculus gularis and is also called Oberholser’s fruit dove. Its nomenclature is unusually complicated: it was long known as Ptilinopus epius, but a 2021 review established that the earlier name gularis applies. A 2014 molecular study found the old broad Ptilinopus assemblage to be paraphyletic, leading nine species, including this one, to be moved into Ramphiculus (Wikipedia taxonomic account; Bulletin of the British Ornithologists’ Club; molecular phylogeny).

This endemic occupies moist lowland forest. It was once grouped within a wider maroon-chinned fruit-dove complex that also included the Banggai and Sula forms, so older accounts may combine multiple species and cannot be used uncritically for ecology. The sources opened did not provide a complete plumage diagnosis, measurements, species-specific fruit list, nest, clutch or incubation period. Those facts are omitted rather than borrowed from other fruit doves (Wikipedia account; Wilson Journal taxonomic study cited there).
