The Amami woodcock (Scolopax mira) is considered a prefectural bird of Amami Island. They are a rare species mainly found on Amami and Tokuno islands. These ground dwelling birds are listed as vulnerable on the IUCN red list of threatened species.

Scientific name: Scolopax mira

The Amami woodcock is a master of camouflage. It crouches down low and limits its movements in the leaf litter. When predators approach the woodcock will fly away in most cases.

In this case the female has chicks that she has to protect.

We managed to see one sub-adult, it quickly followed its mothers lead and fled the scene.

The mongoose is the biggest threat to the wildlife of the Ryukyu Islands. It was introduced to the Ryukyu Islands in the1900’s In order to reduce the venomous habu populations. All the islands are still battling this never ending problem.

All the photographs of the Amami woodcock were taken from the car through the back seat window. In the beginning, I had difficulty with the cameras auto-focus system. I adapted by mounting a Light&Motion GoBe light with a 500 search head to my tripod collar. This allowed the auto-focus system to be extremely responsive using the Canon EF100-400mm f/4.5-5.6L IS II USM.

People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.

The Fishing Spiders of the Yanbaru forest By Shawn Miller

Posted on February 8, 2019 by Admin11

The Okinawan fishing spider (Dolomedes orion) is one of the most unique spiders we have on the Island of Okinawa.

My fishing hole

Most fishing spiders are ambush predators. They have the ability to catch prey on the land, on the surface of the water and even underwater. Fishing spiders use vibrations to attract insects like water striders. The spiders vibrations simulate a helpless insect floating on the surface of the water.

Dolomedes sp, Iriomote Island

I have seen amazing photographs of these fishing spiders eating frogs. I personally have observed Dolomedes orion eating insects only.

Dolomedes orion hunting

The beautiful color contrast allows them to blend in with their surrounding environment to avoid being seen.

Dolomedes orion feeding

It is thought that the white reflective leg sections are used to lure in prey when hunting during the daytime, but do they serve a purpose at night?

Please be respectful to the wildlife. If they show any signs of stress or aggression give them their space and move on. Learn more about the Huntsmen spiders of Okinawa

Okinawa Coral snake – Venomous snakes of the Ryukyu Islands by Shawn Miller

Posted on October 5, 2018 by Admin11

The Okinawa Coral snake (Simomicrurus japonicus boettgeri) is a venomous snake found throughout the Ryukyu Islands. They are difficult to find here on Okinawa and are usually found at night. More effort should be focused on conserving this exotic native snake. This beautiful snake has been overlooked and needs to be protected. It is currently listed near threatened on the IUCN red list of endangered species.

Scientific name: Simomicrurus japonicus boettgeri
Local name: Okinawa Coral snake
Distribution: Ryukyu Islands
Habitat: Forests
Diet: Small snakes and lizards
Average size: 30cm -60cm
Color: Black, orange with a yellow and black belly.

They blend in very well with leaves and broken sticks making them hard to find.

When threatened the coral snake will coil its tail. This defense mechanism confuses the predator.

These rare snakes are often found crossing the road at night and sadly I have seen more dead than alive.

The underside of the snake is quite beautiful as well.

The Hyan coral snake ( Sinomicrurus japonicus japonicus) is a subspecies we found on Amami Island. The stripes are less interrupted than the Okinawan coral snake.

Akamata – The Ryukyu odd-tooth snake

Posted on June 4, 2017 by Admin11

The Ryukyu odd-tooth snake (Lycodon semicarinatus) is a non-venomous snake found throughout the Ryukyu Islands. They are fairly common here on Okinawa and are usually found at night. The Akamata is a natural enemy of the venomous Habu snake. They are one of the few snakes capable of feeding on venomous pit vipers. More effort should be focused on conserving this native snake for this specific reason. This beautiful snake has been overlooked and needs to be protected. Sadly I see more dead on the road than alive.

- Scientific name: Lycodon semicarinatus
- Local name: Akamata – Ryukyu odd-tooth snake

- Distribution: Ryukyu Islands

- Habitat: Forests, drainage ditches, and housing areas

- Diet: Snakes, lizards, frogs, snakes, birds, baby sea turtles, and rodents.

- Average size: 100cm -180cm

This was my first time seeing a juvenile akamata pull back and puff out its head to resemble the diamond shape of a venomous pit viper.

Is the coincidence or mimicry? I know this is a common occurrence with other non-venomous snakes around the world. I believe this juvenile snake saw me as a threat.

This rare species is currently listed as endangered on the IUCN red list of threatened species. It’s biggest threats are deforestation, feral cats, dogs and the introduced mongoose.

Okinawan Sword-tailed newt – Endangered species by Shawn Miller

Posted on October 5, 2016 by Admin11

The Okinawan Sword-tailed newt (Cynops ensicauda popei) is an endangered species found on the main islands of Okinawa an Amami. It is currently listed as endangered on the IUCN red list of threatened species. This amphibian is decreasing in numbers due to deforestation and road kill.

Scientific name: Cynops ensicauda popei
Distribution: Okinawa and Anami Islands
Habitat: Forests, wetlands and freshwater streams
Diet: Amphibian eggs, tadpoles, snails, worms and insects
Average size: 100-180mm

Sword tailed newt with stripes

They all have bright orange bellies, which serve as a warning sign to predators that they are poisonous. When threatened they produce a transparent skin toxin.

Poisonous animals are toxic if you eat them or ingest their secretions. Irritations may occur after handling these newts if you have open wounds. Avoid rubbing your eyes or placing your hands in your mouth.

The newt photographed in its natural habitat.

The government has designed specialized wildlife steps for animals that get trapped in roadside drainage ditches. These steps allow the newts to crawl out safely.

Protecting Okinawa’s endangered beetles – Yanbaru forest

Posted on September 21, 2016 by Admin11

Poaching has been a big problem in northern Okinawa. The endemic animals of the Yanbaru forest are highly valued in the exotic pet trade market. The Okinawan Ministry of the Environment and the wildlife protection center are working hard this year to prevent the poaching of these endangered species. The Okinawan’s are spreading the word in the news, local papers, flyers and even monitoring the forest roads at night.

Poaching flyer -Yanbaru

August through September is when people search the forest for the rare Yanbaru long-armed scarab beetle (Cheirotonus jambar). If you see anyone taking this protected species please contact the authorities. I have yet to photograph a live animal. It is one of the rarest beetles in the world.

The giant Okinawan stag beetle (Dorcus titanus okinawanus) is also a high prized specimen in the pet trade.

Beetle collectors use fruit filled net traps to lure in the beetles.

Over the years, I have found a few traps with dead beetles attached.

In 2019 I found this undescribed beetle in the Yanbaru forest.

Beetle collecting is popular on Okinawa. Its important to be familiar with the specific beetles that are protected species. Let’s protect the wildlife of the Yanbaru forest for future generations.
