Mangaia, Cook Islands.
Usually considered conspecific with T. tutus, but differs in voice, consisting of apparently two calls not heard from tutus, with none of latter’s “noisy chattering” (3); green of mid-crown extending onto forehead as almost complete cap (2); pale rufous vs white supercilium, nape and neck side (2)#R. A recently published and near-comprehensive molecular phylogeny for Todiramphus in the Australasian and Pacific regions has provided additional support for the split, by demonstrating that all three subspecies of T. tutus are each other’s closest relatives, but ruficollaris, while belonging to the same clade, is sister to T. veneratus#R. Shortly after its publication, present specific name was thought to be preoccupied by the taxon described as “Alcyone ruficollaris”, which at the time was listed under T. sanctus; as a result, substitute name mangaia was introduced; however, “Alcyone ruficollaris” was then shown to refer to a form belonging in Ceyx azureus, leaving the name ruficollaris available and valid for present species#R. Monotypic.
