Owls of Okinawa by Shawn Miller

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!

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

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

The farmers in Onna village put up this deterrent to keep the crows from coming back.

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.

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 a 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 behaviour 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.
