Posted on June 1, 2018 by Admin11

The Okinawan tree lizard (Japarula polygonata polygonata) is found throughout the Ryukyu Islands. It is listed as Vulnerable on The Okinawa Red Data Book of threatened species. Habitat destruction and collection have greatly reduced the populations of the beautiful reptile.

- Scientific name: Japarula polygonata polygonata

- Common name: Okinawan tree lizard or Monkey lizard

- Distribution: Ryukyu Islands

- Habitat: Trees and bushes

- Diet: Insects

- Average size: 17-27cm

Color: Green and yellow

A great place to see this beautiful lizard is in the Yanbaru forest.

If you’re lucky you can find one eating an insect or two.

Sometimes the monkey lizard is not so lucky. It is the Ryukyu odd-toothed snakes favorite meal.

Pryers Keelback Snake – Reptiles of the Ryukyu Islands by Shawn Miller

Posted on March 11, 2018 by Admin11

As of March 2018, The Pryers Keelback (Hebius pryeri) is considered a venomous snake found throughout the Ryukyu Islands. They are rear-fanged and require a strong long-term chewing style bite to inject the venom into the wound. They are a very common snake found on Okinawa. I often find them in the Yanbaru forest on my night dwellings.

Scientific name: Hebius pryeri
Local name: The Pryers Keelback
Distribution: Ryukyu Islands
Habitat: Forests, grasslands, streams and rice fields
Diet: Frogs, frog eggs and small reptiles
Average size: 60cm-115cm
Color: Black & yellow with yellow bell

This year (2018) the Okinawa government posted some education posters to bring awareness about the snakes of Okinawa. I was surprised to see the Pryers Keelback is now considered venomous.

The Pryers Keelback mainly feeds on the small frogs. Its favorite meal is the Kajika frog!

They generally feed on the animals head first.

Sometimes you will see them eat frogs feet first. This makes for a more interesting photograph.

Owls of Okinawa by Shawn Miller

Posted on January 26, 2018 by Admin11

Okinawa has three resident species of Owls. They generally live in trees in mountain forests, forest parks and sometimes in residential areas. All three owls are fairly small (20-33cm). They are hard to find in the day, but as night falls their large shiny eyes give them away. These beautiful night dwellers feed on small lizards, rodents, frogs and insects.

The Collard Scops-owl (Otus lempiji) has beautiful red eyes and short pointy ears. It can be challenging to photograph owls. You have to be fast acting with your camera, the owls will fly off quickly after a few photographs.

This is an example of undesirable red eye reflected (Red-eye) below. You generally want to try to avoid this but, I only had had a few shots with the flash on the camera, pointing straight at the owl high in a tree.

The Brown hawk owl (Ninox scutulata) is the most abundant of the three small owls. It has beautiful bright yellow eyes. This owl looks more like a hawk than an owl.

The Ryukyu scops owl (Otus elegans) is mainly found in the northern part of Okinawa. The Yanbaru forest is a designated wildlife protection area.

The owls are often found hunting on forest roads. The insects are attracted to the roadside lights which bring in the owls. The bush cricket (Mecopoda elongata) is one of their favourite meals.

I wonder if the owls can see fluorescence. Many of the stick bugs, grasshoppers and crickets fluoresce under blue light,

Sadly I have seen more dead owls than alive!

Ryukyu Long tailed Giant Rat – Ryukyu Islands

Posted on January 21, 2017 by Admin11

The Ryukyu Long-Tailed Giant Rat (Diplothrix legata) is an endangered species found on Amami, Tokuno and Okinawa Island. 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. I often see it crossing the road during the night in the Yanbaru forest. Please pay attention to crossing wildlife and drive at a safe speed.

The Yanbaru forest is designated as a wildlife protection area by the Okinawan prefecture, It extends from Nago to Kunigami village.

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 Art of Wide-Angle Macro Photography by Shawn Miller

Posted on December 20, 2014 by Admin11

Wide-angle macro photography is popular with wildlife photographers. The technique allows the photographer to document the animal in its natural habitat and show the full scene it lives in. The photographs have great impact and deliver a bug eye perspective using a wide angle lens. I generally use off-camera flash with a custom soft box to make these photographs. Lately, I have been testing a variety of on-camera flashes to achieve a different perspective. One of the biggest challenges is lighting the subject evenly with soft diffused lighting.

The most popular lenses used for wide angle macro photography ( WAM )

Tokina fisheye 10-17mm f3.5-4.5
Nikon fisheye 10.5mm f2.8
Sigma fisheye 15mm f2.8 E
Venus Laowa 15mm f4 – (Manual focus only)

The Tokina 10-17mm Fisheye is my favorite lens in my bag and has been my go-to lens for the project “Crabs with Beach Trash Homes”

The woodpecker can rotate its head 180 degrees to capture the difficult insects. This is the first and only time I have observed this occurring.

Ryukyu black-breasted leaf turtle, Yanbaru forest

Posted on November 10, 2014 by Admin11

The Ryukyu black-breasted leaf turtle (Geoemyda japonica) is an endangered species found in Northern Okinawa. This turtle is decreasing in numbers due to poaching, deforestation and roadkill. The turtle is highly valued in the pet trade market and needs to be protected. It has been designated as a National Natural Monument of Japan and is currently on the IUCN red species list as endangered.

Scientific name: Geoemyda japonica (Fan, 1931)
Distribution: Okinawajima
Habitat: Leaf littered wetland forests
Diet: Worms, snails, insects, crustaceans, and fruit
Average Size: 140mm- 160mm

This leaf turtle was not painted red or yellow. I photographed it using specialized blue lights and filters. The shell fluoresced bright yellow and the algae grow fluoresced bright red.

Slow Down! – Let’s Protect The Okinawa Rail

Posted on August 26, 2014 by Admin11

The Okinawa rail 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

Distribution: Northern Okinawa

Habitat: Forests

Diet: Small insects, worms, snails and fruit.

Average Size: 31cm

Threats: Habitat loss and the threat of Jungle crows and mongoose.

The rail is often found feeding on the side of the road. It feeds on worms, snails, and insects.

Okinawa rail posing ( Hypotaenidia okinawae)

When defending its territory, the rail will become aggressive and flare its wings.

If you are lucky you can catch the Okinawa rail feeding on the fruit of the cherry tree.

Okinawa rail feeding ( Hypotaenidia okinawae)

They roost high above the ground to avoid predators like the habu snake.

Okinawa rail roosting ( Hypotaenidia okinawae)

In 2014 I stumbled upon Scientists handling an adult Okinawa rail in the wild.

Awareness signs are posted along the main roads in northern Okinawa for their protection. I think they should also include speed bumps in the designated crossing areas for the rails.

The speed limit is only 40km/h so watch your speed for the protection of the wildlife. The rails are often seen feeding on the side of the road.

I have observed these birds crossing the road on many occasions. They have no problems crossing when people are driving the speed limit. Speeding decreases your reaction time, slow down and pay attention to all crossing wildlife.

What to do if you find an injured rail.

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.
