The Good, the Bad or the Evil – The Crow’s of Okinawa

Posted on October 1, 2017 by Admin11

The Jungle Crow (Corvus macrorhynchos) is found throughout the Ryukyu Islands. They are abundant here and can be found all over Okinawa. Populations have increased due to the readily available food, left on the side of the road and in dumpsters. It’s important to keep your trash enclosed in cages to prevent the crows from getting to it.

Scientific name: Corvus macrorhynchos
Local name: Jungle crow
Distribution: Ryukyu Islands
Habitat: Farms, cities, forests and grasslands.
Diet: Eats almost everything
Average size: 50cm body length
Color: Black

Crows can be vicious predators. They often harass other birds, showing off their strength.

These intelligent birds work as a team to get what they want. I have personally seen them raid baby birds from the nest. I have seen them fly away with juvenile woodpeckers, rails and swallows.

To control the population of jungle crows in northern Okinawa, they use large traps to catch them in. One way in and no way out!

Possibly a strange growth that occurred from an injury (broken beak). Could this be one of the few crows that made a successful escape from a trap?

As much as we dislike the crow, they do have a purpose in the ecosystem. They clean the dead animals (road kill) off the road, keeping our environment clean from rotting carcasses. I often see them feeding on cats, snakes, lizards, birds, and rats dead in the road.

On several occasions, I have observed crows eating dead animals on beaches and river banks. Met EEL-Zilla, a huge freshwater eel that washed up at Nagahama dam.

They also feed on the large green caterpillars that destroy the farmer’s taro (Taanmu) crops in Kin village

Mutualism of Commensalism?

I believe this is Mutualism. Both animals possibly benefit from each other. The crow cleans the parasites on the boar’s skin and also acts as a warning system when threats are in the area. The wild boar uproots the ground, which gives access to insects, grubs, and worms for the crow. This was my first time observing this behavior in the wild.

As soon as the boar spotted me it fled the scene. The crow attempted to stay mounted but could not keep up with the boar.

Seashells of Okinawa by Shawn Miller

Posted on May 20, 2017 by Admin11

The beautiful seashells of the Ryukyu Islands.

It all started in 1989, I went to a friend’s house and saw some beautiful seashells displayed on a counter-top. My first thought was that they were fake or man-made. The intricate design of the Venus Comb Murex shell caught my eye. I was fascinated by the design and wanted to learn more about the animal that produced this beautiful shell.

I continued to collect, photograph and read more about marine mollusks from the Ryukyu Islands. I eventually started contributing my collection samples to worldwide museums, scientists, specialists and images for various scientific publications. I currently do not collect shells anymore but enjoy photographing the marine snails in their natural habitat.

General rules to shell collecting

Be respectful of the environment.
Only collect dead specimens
Avoid over collecting sea-shells
If you turn over rocks, place them back in the original position
Return all unwanted shells back to the coastline

Below are some of my favorite shells found on Okinawa.

Meet Your Neighbours project – Okinawa, Japan

Posted on October 22, 2016 by Admin11

Founded in 2009, Meet Your Neighbours is a worldwide photographic initiative created by Niall Benvie and Clay Bolt. The project is dedicated to reconnecting people with the wildlife on their own doorsteps and enriching their lives in the process. These creatures and plants are vital to people: they represent the first, and for some, the only contact with wild nature we have. Yet too often they are overlooked, undervalued.

There are seventy-five worldwide contributors to this powerful project. I am currently the Japan contributor to this project. All images are used for conservation awareness and educational purposes. Below are some of my favourite images.

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.

Testing the Venus Laowa 60mm F2.8 macro lens underwater

Posted on July 20, 2015 by Admin11

Dive Team Miller Underwater set-up with Canon 70d Laowa 60mmn f2.8 macro lens- Ikelite housing with 8inch dome port, 1 ikelite 160 strobe , 1 ikelite 200 strobe, 1 sola 600 and 1 gobe 700 focus light.

The Venus Laowa 60mm macro lens is a technical lens with great optics. The specialized lens is manual focus and manual aperture selection. I had to use my wide angle dome port since this was the only port I had the lens would fit into. I preset the lens to a 1:2 ratio and used an aperture setting of F8. I went with the aperture setting of F8 since it was an overcast day and I wanted to see my subject through the viewfinder in the low light. I used two modeling lights to add artificial light, which allowed me to see through the viewfinder at a depth of 100 feet. The focusing distance was already preset on the surface, so all I had to do was to move the camera until I saw the subject was in focus and take the shot. It was very difficult to use with subjects that were moving. This was my first dive using this lens underwater and have more testing to do. Here are some of my images using the Venus Laowa 60mm macro lens underwater at Maeda point, Okinawa-Japan.

Test dive two, I set the aperture to F11 with a focus distance between 1:1-1:2. It was challenging working with all moving subjects. The dome port was to close for comfort for moving subjects such as fish. Stay tuned for more images later this week!

Capturing fluorescence – Fluorescence enhancement photography by Shawn Miller

Featured

Posted on March 31, 2015 by Admin11

All photographers experience a time when their work becomes redundant and lose vision. The Light & Motion Sola Nightsea has opened up a new style of photography for me. Recently I have been blending the Light&Motion Nightsea blue light with ambient light underwater and getting beautiful vibrant results.

Some of my Fluorescence enhancement coral images were featured in The Blue Planet 11 publication. It’s always nice to see years of hard work finally pay off.

Fluoro fingerprinting by Shawn Miller

Posted on February 21, 2015 by Admin11

On February 16th 2015, I went out reef walking at night during low tide. I brought my Light and Motion Nightsea blue light in search of marine life fluorescence. I stumbled upon an interesting find in the world of science. I call it Fluoro fingerprinting.

I flipped over a rock, a small sea cucumber fell off and began to fluoresce under blue light. I found another sea cucumber and photographed it using the blue light and yellow excitation filter but it did not fluoresce.

Holothuria (Platyperona) difficilis under blue light

I gently touched it with my finger and it fluoresced bright green, leaving the print of my finger on the surface of the sea cucumber.

I checked my finger and noticed it fluoresced light green under blue light.

Fluoro fingerprinting

I was excited about this find and posted it Flickr for some Identification help and explanation. Curt Fieldler emailed the photograph to Dr. Alexander Kerr from the University Of Guam Marine lab and he was kind enough to assist.

Dr. Kerr stated that the species is known to have green pigment that I have seen in other Sea cucumbers. As far as the fingerprint, It seems to indicate that touching the surface of the Sea cucumber exposes the underlying carotenoid, perhaps by mobilizing the the melanin pigments. So I think you have made an interesting find.

The next step was to photograph Holothuria (Platyperona) difficilis in a studio aquarium using the Meet your neighbours isolation technique. I wanted to show the animal stretched out displaying the tube feet and feathery feeding tentacles.

The last step was to photograph Holothuria (Platyperona) difficilis in its natural environment during the daytime.

Kuroiwa’s Ground Gecko, Endangered species of the Ryukyu Islands!

Posted on November 18, 2014 by Admin11

Kuroiwa’s Ground Gecko is a beautiful lizard found throughout the Ryukyu Islands. It is currently listed endangered on the IUCN red list of threatened species. This lizard is decreasing in numbers due to poaching, deforestation, and the threat of feral cats. The lizard is high valued in the illegal pet trade market and needs to protected. This is one of my favorite reptiles to photograph on my night adventures in Okinawa.

- Scientific name: Goniurosaurus kuroiwae

- Distribution: Okinawa Islands

- Habitat: Leaf littered forests

- Diet: Worms and insects

Average Size: 110mm -130mm

Shawn Miller Featured- Wildlife As Canon Sees. National Geographic October 2017

This is the first ground gecko I photographed in 2010. I found it under a piece of carpet in Onna Village. Illegal dumping is a huge problem in Okinawa.

In the daytime, they live in caves, crevices, and holes in the ground

They come out to feed at night.

When they feel threatened they will stand up on all fours and try to intimate you with a stare down.

They have some strange looking feet –

When I approached this ground gecko it stayed in place. I found three Mosquitoes sucking the blood right out of it. the first time I observed mosquitoes on a lizard.

The juveniles have vibrant orange stripes down the back and rings around their tails.
