I Finally Found the Yanbaru Kuina

Posted on November 9, 2019 by Admin11

When I tell people I am a nature photographer, they often ask me if I have ever seen a Yanbaru kuina. Friends are always so excited to tell me that they found a Yanbaru kuina in central Okinawa. I feel bad telling them the bad news. More than likely, they found a common moorhen. The common moorhen is often mistaken for the Yanbaru kuina.

The Common Moorhen (Gallinula chloropus) has a bright red head shield, yellow legs with distinctive white feathers underneath. The Common moorhen is found near marshes, local parks and small rivers. This bird is very common in Okinawa

Scientific name: Gallinula chloropus
Common Name: Common moorhen
Distribution: Okinawan wide
Habitat: City parks, rivers and creeks
Diet: Vegetation and small aquatic animals
Average Size: 30 to 37 cm

The Difference: The Yanbaru kuina ( Okinawa rail ) has an orange beak with bright orange legs. The underneath is black with white bars.

The Yanbaru kuina is a flightless bird found in northern Okinawa. It is a protected species and declared a living natural treasure. It is currently listed by the International Union for Conservation of Nature (IUCN) as an endangered species. In 2012 populations of this endemic bird were estimated at 1500 by the Environment Ministry. As of October 2016 populations have declined to 480 mature individuals according to IUCN assessment.

Scientific name: Hypotaenidia okinawae
Common Name: Okinawa Rail
Japanese Name: Yanbaru kuina
Distribution: Northern Okinawa
Habitat: Forests
Diet: Small insects, worms, snails and fruit.
Average Size: 31cm
Threats: Habitat loss, and the threat of mongoose and feral cats.

Psychedelic Spiders of Okinawa by Shawn Miller

Posted on July 30, 2018 by Admin11

I have been photographing fluorescence for over five years now. Mainly underwater but lately I have been testing the technique on land. I often find insects, spiders, and plants that fluoresce using a specialized Light&Motion Sola Nightsea light. Some of the micro-spiders fluoresce brightly under blue light, the challenge is to get an acceptable photograph.

Below are some comparison photographs of spiders. The first photograph was taken under blue light and the second under white light using on-camera flash. All the spiders were photographed in their natural habitat on the beautiful Island of Okinawa.

I used my nauticam underwater setup with NIGHTSEA’s fluorescence excitation filters to photograph the wood spiders.

Light and Motion lights produce constant lighting with studio quality output. This light configuration is convenient while shooting macro photography at night. The camera, tray, arms and lights are combined into one lightweight unit. The light output can be easily adjusted with a touch of a switch. Having the lights on loc-line arms allow simple light angle adjustments.

The custom Light and Motion macro field setup consists of

Sola Tray kit with extention tray and arms
Third custom loc-line arm mounted
GoBe 700 wide light
Sola 600 light
Sola 1200 light
Canon 70D with 60 mm macro lens and strap

I was fortunate to have beautiful weather both nights testing the constant lighting setup in northern Okinawa. Six of the animals below are endangered species listed as threatened on the IUCN red list. All of these night dwellers are decreasing in numbers due to deforestation.
