The Kofiau paradise kingfisher, known scientifically as Tanysiptera ellioti, is a resplendent tree kingfisher of the family Alcedinidae, within the subfamily Halcyoninae. This species is adorned with a striking plumage; the head and upper parts exhibit a dark blue hue, while the rump, tail, and underparts are a contrasting pure white. Notably, the central tail feathers are elongated and taper to a fine point, and the bird's bill is a vivid scarlet, adding a splash of color to its already vibrant appearance.
