Olive pigeon explained

The olive pigeons are four allopatric species of pigeon, named for their association with olive (Olea) species.^[1] They have a maroon tone to the speckled plumage, and inhabit cool, montane forests of Africa and its associated islands. Together with the speckled wood pigeon, they are seen as members of a superspecies,^[2] which has affinities with the white-naped pigeon.
