Description

The Ryukyu flycatcher weighs around 12 grams (0.42 oz), with males typically being larger than females. The male is the more colourful sex too, possessing a yellow lower back and rump, yellow-orange underbelly, orange bib, and yellow-orange streaks above its eyes; all contrasted against bluish-black plumage. [3]

Taxonomy

The Ryukyu flycatcher has previously been considered conspecific with the narcissus flycatcher and the green-backed flycatcher, only recently being granted full-species status. [4] However, some of the more northern-ranging populations are considered somewhat intermediate with the narcissus flycatcher. This revision was based on differences in shades of plumage and the Ryukyu flycatcher's songs, which are made up of shorter phrases and fall within a narrower frequency range. [5]

Conservation

Not much is known about this species but it's not considered to be threatened. [3]
