Okinawa Rail is a type of bird Friend that first appeared in the original Kemono Friends mobile game.
Appearance
Okinawa Rail has pale skin and bright red eyes. Her hair has an unusual shape; the main part is long, feather-y, and ruffled, going down to the middle of her back. It is black on the top and olive brown on the underside. There are two equally long white strands at the side that have a slight outward curve. A single center bang is bright orange-red with a yellow tip, representing the real life animal's beak. A red hibiscus flower rests on the top left side of her head.
She dons a black turtleneck sweater with "gloved" hands. A black-and-white sweater vest with her signature barred feather pattern and olive colored sleeves covers her turtleneck. Her pleated skirt is the same black as her undershirt. Lastly, her leggings and sandals are both solid orange-red.

In Real Life
The Okinawa rail (Hypotaenidia okinawae) is a bird in the rail family, Rallidae. It is endemic to the island of Okinawa, Japan, specifically the northern part of the island called Yanbaru. In its home country, the bird is known as the Yanbaru kuina (ヤンバルクイナ (山原水鶏).
It is a bird on the smaller side, about 30 cm (11 in.) long with a wingspan of 50 cm (19.6 in.), and weighs about 435 grams (.095 lbs.). The upper part of the body is an olive brown whereas the underbelly is black with narrow, white bars. Probably the most distinct feature is the bright red, white-tipped beak. Its long legs are also a red hue. Young rails are much more pale and have a mottled pattern rather than the signature bars of adults.
Okinawa rails are talkative birds with a variety of loud calls. Those calls are heard most often early and late in the day, usually from the ground but occasionally from trees. Pairs often call together and up to 12 birds have been heard in one area.
Mated pairs are monogamous and appear to mate for life. The nests are built on the ground and made from fallen leaves and foliage. A clutch of 2-4 eggs is laid between May and July. The eggs are small, oval-shaped, and white with reddish, pinkish, or brownish markings. Chicks are born with solid black downy feathers, yellowish legs and feet, and a white bill.
Being endemic to the Yanbaru section of the Okinawa island, their habitat range is very small, a grand total range of just 260 km². It can be found from sea-level to the highest mountains at 498 m (about 1,633 ft.) above sea-level. Come winter though, some birds will move lower down or move a bit further south of the preferred breeding range. It prefers evergreen forests but will also occur in marshes, grasslands, and cultivated lands, so long as its close to forests and water. The rails require dense ground vegetation as well as standing water for bathing.
Food is mainly taken from the dense forest floor, but may also be taken from the shallow waters which it bathes. Okinawa rails are known to eat lizards, amphibians, snails and large insects such as locusts.
The Okinawa rail species is classified as endangered by BirdLife International because of its small, declining population and restricted habitat range. In 1986, the total population was estimated at around 1,800 birds. Surveys made between 1996 and 2004 suggested a significant decline to a mere 720 birds and a "northward contraction of the range" of about 40%. However, a follow up survey done in 2006 found no further range contraction. The species is now legally protected in Japan and has been declared a "natural monument" and a "special bird for protection". Not only it has a captive breeding program been planned for sometime in the future, the Japanese Ministry of the Environment has laid out a 10-year action plan with steps it plans to take to stabilize the species' numbers.
Trivia
- The species was only recently discovered, first being described in 1981 by Japanese ornithologist Yoshimaro Yamashina.
- One of its main predators is the Okinawan Habu, a venomous snake.
- Okinawa rails are not suited for flying, but are great runners.
- Its home range of Yanbaru became a national park in 2016.
