Do not pass Crow (do not collect $200)

Hi blog.

Here is an interesting article from late last month.

Crows have a poor reputation, but I think part of the problem is that humans don’t know how to deal with a vastly intelligent animal that is using that vast intelligence to survive in a world we keep changing.

I’ve seen crows pick up the yellow netting used to cover garbage – they don’t have to be able to see through the netting to know that there is garbage under it.  (Apparently crows can not see the yellow spectrum well and the net is supposed to disguise the garbage)

But here is a case where people make use of the birds’ behaviour to avoid conflict.

‘Crows do not enter’ signs keep the winged pests at bay in Iwate

OTSUCHI, Iwate Prefecture–Since the “crows do not enter” signs went up at a university research center here, the pesky birds have quit raiding it for nest material.

Katsufumi Sato, a professor of ethology, put up the first set of signs in 2015 after taking advice from his friend Tsutomu Takeda, a researcher of environmental medicine and “crow expert.”

Takeda suggested putting up the warning signs at the International Coastal Research Center (ICRC) of the Atmosphere and Ocean Research Institute, the University of Tokyo.

Sato first thought his friend was kidding, but he gave it a try. In no time at all, the crows stopped targeting the research center in northeastern Japan.

The professor expected the lull was perhaps temporary and down to luck, but, no, the crows continued to stay away.

In mid-April, Sato was hanging the new warning signs for the spring that prohibit crows from coming into the building that were written on sheets of paper. They were hung on broken window frames and pipes on the ground floor of a research center building that was inundated with water after the tsunami spawned by the 2011 Great East Japan Earthquake.

This year was the third “round” of his so-far successful war against the bothersome birds.

The foul avians target the insulation material covering the pipes, tearing it off and flying away with their “loot.”

“Crows take it for their nests,” said Sato with a bitter smile.

The predecessor of the current research center opened in 1973 as a base for international marine research, but on March 11, 2011, the tsunami hit, reaching even the top floor of the three-story building.

The third floor was later repaired for temporary use, but the first and second floors were not and after debris was cleared, they became warehouse space.

The crows’ first full-on invasion took place in the spring of 2015, according to Sato.

The insulation material on the pipes along the exposed ceiling of the first floor were torn away but there was tell-tale evidence of whom the guilty party was–crow feathers and bird droppings scattered about.

The houses around the research center were all destroyed, and the residents have moved to other areas.

As the ICRC building’s windows and doors had been left without glass panes on the bottom two floors, it was easy pickings for the airborne marauders.

Sato was consulted by research center staff, but could not provide a decisive solution.

In a flap, he turned to Takeda, who works at the Center for Weed and Wildlife Management at Utsunomiya University.

So, have the crows been reading books and studying written Japanese? Not quite.

Takeda said the crows are actually scared off by ICRC staff and students looking and pointing their fingers at them after seeing the strange signs.

“People gaze up at the sky (looking for crows), you know,” said Takeda.

This year, Sato put up a few dozen signs. There are few crows flying around. People coming to and going from the center see the signs and look up to the sky.

“The effectiveness will increase if there are more people looking at the crows,” said Sato. “So please feel free to visit us!”

Article ends.

TV news was a little more forthcoming with information in that wild crows don’t like being pointed at or stared at – gosh, they’re just like me – and will avoid areas where they a the centre of unwanted attention.

Avian psychology wins!

Badgering On

Hi blog.

Sometimes I am genuinely surprised at how little the locals know about their native wildlife.

A point in case was during Golden Week and my family went camping near Shomaru Pass.  The campsite was very much unknown and we had the whole place to ourselves for one of the two nights spent there.  Deer could be heard at night and even left their calling cards (although we did not actually see any deer), we saw what I believe was the same Japanese rat snake on two consecutive days, heard and spotted a couple of kites and caught two freshwater crabs (which we released the following day).  However, the highlight – for me, at least – was during our hike up to Shomaru Pass.

There is a well known cafe/restaurant at the top of the pass, and we were walking up to have an early lunch.  I tried to encourage the kids to keep their eyes and ears open – I spotted several lizards by noticing the rustling of leaves on the ground.  At a point not far from the top I could hear dripping water and paused to find the source.  At that moment a small head and pair of feet popped out from a covered gutter.  The animal was the size of a small dog, and had dark rings under its eyes, it had round ears and a pointed face.  Both my son and I recognised it instantly. (Those hours spent at Inokashira Park Zoo had paid off.)

A badger!

Unfortunately, I had no time to squeeze off a photo before the badger disappeared back into the darkness and refused to show its face again.


The Japanese badgers at Inokashira Park Zoo

A wild badger is something the vast majority of Japanese will never see.  What’s more, I was surprised at number of people who drew a blank when I told them about my encounter with a badger.  For many – even the good wife who caught a glimpse of its paws – the animal known as the badger simply fails to register.

One reason, as I’ve mentioned before on this blog, are the superficial similarities between badgers and the much better known raccoon dogs.  This is not a recent phenomenon, as even the Wakansansaizue contains no mention of badger at all.

Tokyo Zoo Net has some nice video images of raccoon dogs and Japanese badgers which really highlight the differences between them.

Racoon dog

Japanese badger

Another reason is the similarity of the names in Japanese.  As my avid followers would know, the Japanese name for badger is anaguma (穴熊) – literally “hole bear”.  Because of the bear in its name, too many listeners automatically assume the animal is a kind of bear.

Others simply confuse the name for that of the introduced raccoon – araiguma (洗熊 or 浣熊, but usually written in katakana) in Japanese.  Furthermore, the raccoon was the star of a Japanese animated series, but Japanese badgers have never had that kind of publicity.  In fact, I have not found them mentioned in any traditional children’s stories and, indeed, I couldn’t find any pre-modern references to badgers at all.


The cartoon that encouraged the import of thousands of raccoons into Japan.

Other people responded to my story with the question, “Are there badgers in Japan?”  Either they were confusing badgers with raccoons, or had some vague background awareness that there is an animal known as a badger but couldn’t imagine it being a Japanese native.  Even when I specified “Japanese badger”…

Educating people about Japanese badgers has become part of my wider mission.

I Shot the Stork…

Hi blog.

This is one of those “JUST WHAT THE **** WERE YOU THINKING?!” moments.

A hunter, culling herons (?) , managed to kill the only female stork currently nesting outside the Toyooka stork breeding program.  At 30 metres range and front on, he mistook the bird for a heron.  (TV news went to great lengths to show how front-on the two birds look similar.. I mean, they are both birds.  AND… they are both white, and…err…)

Protected white stork shot by mistake in Shimane

Hunter shoots rare stork by mistake

KYODO — An oriental white stork, a species designated as a special national treasure, was mistakenly killed Friday by a hunter in Shimane Prefecture, the local police and education board said.

The education board said that a member of a hunting group shot the female stork after mistaking it for a heron.

The Unnan City Education Board said the 5-year-old stork laid eggs in March and that four had hatched so far.

Since Japan’s wild storks disappeared in 1971, this was only the second such hatching in the wild that was not part of the breeding project in and around Toyooka, Hyogo Prefecture.

Since 2007, the large black-and-white birds with long beaks, necks and legs have been breeding in the wild around Toyooka, home to a major rearing facility called the Hyogo Park of the Oriental White Stork.

Satoshi Yamagishi, head of the park, said the accident was very regrettable.

“I can guess how local people waiting for the fledglings feel,” he said, adding that he hopes the chicks grow up safely.

Article ends.

The chicks have been taken the the Toyooka facility where it is hoped that they can be raised and released into the wild.

And, hopefully, they WON’T BE MISTAKEN FOR HERONS.

Why did the pheasant cross the road?

Hi blog.

This is an example of one of those magic encounters, when one simply stumbles across wildlife and has time to get visual evidence.  Enjoy!

And I think the answer to the titular question was that the female was in the other field.

Eats Shoots and Leaves

Hi blog.

Spring is in full swing, with the leaves out on virtually every tree.  Unstable weather is with us as storm clouds suddenly appear and disappear.

The first part of this post was seeded several years ago when we visited the wife’s family out in the countryside and her cousins went to harvest some shoots from what looked like a spiky sapling.  I wasn’t able to get a photo at the time and so the idea for the post went into hiatus.

That hiatus thawed when I was riding to work recently and spotted someone harvesting shoots from a spiky plant.  A couple of photos on the way home ensured the seeds of this post germinated.

You wouldn’t guess that this plant is the main star of this post, would you? The taller of the two trees was about 2 metres in height.

The plant in question is the Japanese angelica-tree or Korean angelica-tree (Aralia elata), known in Japan as the taranoki (楤木 of 桵木).   This tree can reach heights of up to 10 metres, but typically grows between two and four metres tall.  It is a slender tree covered with a rough grey coloured bark and spines.  The pinnate leaves grow to between 50 cm and 100 cm, with individual leaflets about 5 cm in diameter.  Each of these leaflets also have spines along the veins.  (This page has lots of close up photos of A. elata, especially of the individual parts)

With so many spikes, it is hard to imagine this plant being any use at all.  However, for a few weeks in spring it produces tender shoots with no spines, which may be harvested and eaten.  In Japan, the most popular way of eating the shoots – called taranome (楤芽) – is as tempura.

A shoot, too small to be harvested.

When harvesting from wild plants, especially those on public land, it is important to leave side shoots, otherwise the tree will die.

Some of the spines covering the trunk.


The second part was inspired by events last year when I helped harvest bamboo shoots.  I didn’t have any chances to take photos that day.  However, I was prepared this time around and managed to sneak in a couple of shots.

A partially dug bamboo shoot.

Bamboo shoots are best harvested just as the tip breaks the surface, but these can be hard to find.  There certainly weren’t as many as last year, and it appears that some wild pig had beaten us to some.  (I didn’t get a photo of the pig’s diggings as it was virtually indistinguishable from where the humans had been digging!)

The harvest wasn’t as good as last year.

Several kinds of giant bamboo are harvested in their shoot form, so I can’t tell you the species.  All I know is that the bamboo rice was pretty good!

Hi blog.

The school year is up and running.  The first week of the school year is mostly administration and I don’t have so much to do, but now lessons are underway and I’m busy again.

Thinking back to March when the school year was drawing to a close and how some of the teachers filled in those “dead” lesson periods – assessment was over, there was nothing to be gained from trying to teach the kids anything, but…  Anyway, I noticed that one social studies teacher was showing his kids Princess Mononoke, and I was wondering if he had any questions up his sleeve to get the kids at least thinking.

One element of Princess Mononoke that has always confused me is Ashitaka’s mount.  It is clearly not a deer, nor does it resemble any Japanese mammal that I know of.  Furthermore, the creature is recycled from one of Miyazaki’s earlier works The Journey of Shuna.  Some sources, however suggest that the animal is (loosely) based on the Japanese serow.

Yakkul (spelling?) as he appears in Princess Mononoke. The horns of Japanese serow rarely, if ever, exceed the length of the ears.

The Japanese serow (Capricornis crispus), known locally as kamoshika (usually 氈鹿 or 羚羊 ) but correctly as Nihon kamoshika (日本 氈鹿) to prevent confusion with other ungulates.  An older name was niku (褥), basically meaning “mattress” or “rug”.

Perhaps because “kamoshika” can be loosely translated to mean “antelope”, one can see how a creature most closely resembling an eland of Africa appears in Miyazaki’s medieval Japan setting.

Rather than antelopes, Japanese serow are more closely related to goats.  Their stocky bodies are covered with thick hair which may range from white to black, the area around the neck typically being white.  The coat typically becomes a lighter colour in summer.  Both males and females grow backward curving horns, which continue growing throughout the animal’s life but almost never exceed the length of the ears.

Here you can compare the length of the horns to the ears.  The eyes are very goat-like

Japanese serow live in broad-leaf or conifer forest areas around deep mountains in northern and eastern Honshu, and parts of Shikoku and Kyushu.  They are sometimes spotted on the slopes of Mt. Fuji, although it is safe to say that the average Japanese person is not familiar with them at all – many people think that serow are a kind of deer due to the name.

Serow are foragers, feeding on sasa bamboo and other grasses, bark, nuts and fruit, shoots and leaves.  They live alone or in small family groups rarely exceeding four.  They are also territorial and mark their territory with scent glands.  Japanese serow defecate in set areas, which probably also helps mark territory.

Japanese serow have a long and complicated history with humans.  Their numbers dwindled for the usual reasons – over-hunting and loss of their natural environment, reducing the wild population to less than 3000 individuals by 1955, but they have also been labelled pests by foresters.  The serow has also been used as a symbol of conservation, and the animal now enjoys the status of “National Monument Species.

As it appears in the Wakansansaizue.

The Japanese serow has featured on Japanese postage stamps, once on the 1952 ¥8 stamp and again on the 2015 ¥50 stamp.

The 2015 issue ¥50 stamp featuring the Japanese serow.

Interestingly, in Japan, someone with long, thin legs is described as having “legs like a serow”.  This is another case of misinterpretation – the “serow” in the proverb actually being a an antelope or gazelle, not a Japanese serow!

My only confirmed encounters with Japanese serow have been at zoos (an animal spotted running along a road at night in the mountains of Fukushima may have been a serow, but I was unable to identify it), so I hope to correct this situation one day.

Not Just Another Walk in the Park

Hi blog.

April is upon us, which means the beginning of the financial year and academic year, cherry blossom parties, and the end of the end of the extremely short spring holidays.  (I don’t get why the last day of third term and the first day of first term are separated by less than two weeks while first and second terms are six weeks apart)

April 1st was a bit of a joke weather-wise.  The heater didn’t get turned off all day, and rain was persistent.

April 5, however, gave us sun and basically the most glorious day so far this year.  I was to do something with my son, and decided an outing was in order – partially for blog reasons.  My initial suggestion of a walk around Hachikokuyama was rejected immediately, but when I offered Inokashira Park as an option, interest sparked.  A quick internet search of the small zoo within the park sealed the deal.

*Note: The English page for the zoo currently mentions Asiatic elephants.  This is no longer true as Hanako, the oldest elephant in Japan, died in May 2016.  Her enclosure was small and concrete floored, and Hanako had not seen another elephant in decades.

Leaving that sour note behind us, lets take a mostly visual wander around the zoo.  I’ll focus on the native wildlife here, mostly from my son’s attempts at photography…

Before entering the zoo we encountered the “source”…

The spring that feeds the lake and ultimately the river system. There is no longer enough pressure to bring water to the surface and so it is pumped.

The zoo is divided into the main zoo park and the aquatic life park.  My son wanted to visit the latter first.  As we entered the sun was out in all its glory and bush warblers could be heard calling out.  We actually spotted one up a tall tree, but we could make out its movement better than its shape.  Still, I managed to get a recording of its voice.  Turn your sound up for this video.

The outdoor section of the aquatic park houses waterfowl, and the park makes note of is breeding program for Mandarin ducks.

A pair of Mandarin ducks. The bright and gaudy one is the male.

A Japanese crane.

A little egret. I can never get them to hold still for a shot in the wild.

We also spotted people checking fish traps in the lake – I assume they were either surveying the fish population and/or removing alien species.

Checking fish traps. I think this would be a great activity to join.

Most of the shots of the birds are not worth showing, so let’s take a look at the aquarium section.

One of the highlights of the aquarium – a giant salamander. The Japanese giant salamander is the world’s second-largest amphibian.

The head of the giant salamander.

A water spider in a bubble of its own making.

One enclosure was particularly interesting – it contained a pair of little grebes which actively hunted for fish, a large soft-shelled turtle, a Japanese pond turtle and a crested kingfisher.  Only the last one is not normally found within the confines of the larger park area.

A Japanese pond turtle wandering around on dry land.

A soft-shelled turtle. These animals rarely leave the water, making this a rather unusual shot.

High up in a hard-to-see point in the enclosure, a crested kingfisher.

But being able to see those little grebes hunt was something special.

I finally got some pictures of Japanese keelbacks.

A pair of Japanese keelbacks.

A Tokyo salamander. Although they rarely enter the water outside of breeding season, this one was in the water.

Charr and seema. The “kiss marks” on the rocks is where the fish have been feeding on the red algae.

After we had finished in the aquatic park we crossed over to the main zoo.  While this zoo houses a variety of animals from around the world, it boasts a collection of native Japanese mammals and birds.

A Japanese serow. I might get around to writing about these someday…

A Ural owl.

A Tsushima leopard cat.

A pair of Japanese badgers at play.

A copper pheasant. These birds tend to live in the deep mountains.

There is a squirrel enclosure which visitors can enter and experience squirrels running around them.  My memories of Hokkaido include seeing wild squirrels in the large park, but they are a different species.  People around Tokyo rarely, if ever, see wild squirrels.

A Japanese squirrel foraging in the enclosure.

While my son was keen for the civets to wake up, they didn’t.  However, one the Japanese martens became active later in the afternoon.

At just ¥400 for adults and free admission for kids under 12, Inokashira Park Zoo is possibly one of the cheapest and best value days out in Tokyo.  And that doesn’t include the rest of the park!

A Walk in the Park

Hi blog.

I’ll spare you the excuses, mostly because I have none.

We are into late March, meaning the end of the academic and financial years, unstable weather – one day’s minimum might be higher than the next day’s maximum, rain one day and dust storms the next – and cherry blossoms and the hype surrounding them.

Feeling somewhat low over the spring equinox long weekend – right after my 45th birthday, no less – I decided to take the plunge and go out in search of something to blog about.

This will be a mostly visual post.  I cycled to Tokorozawa Aviation Memorial Park (it feels so strange to call it that – everyone I know uses “Kokukoen”) in the hope of seeing something worth photographing.  And something I could photograph with my not-so-great smartphone camera.

A Trachycarpus palm, one of the evergreens found in this area.  I should get around to writing about them some day.


Small bracket fungus growing on a tree stump.


Mississippi red-eared sliders vie for the best basking spot on what was the warmest day so far this year.


A yulan magnolia in full bloom. Avid followers might recognise this.


They smell better than those cherry blossoms too.

On the way to the park, along the banks of the Azuma river. White, pink and red camellias under a cherry tree and palm.

Sometimes a walk in the park is just what one needs.

The monkey killers

Hi blog.

It looked like I wasn’t going to get a post out this month.  I was toying with one about the starlings in the area, but couldn’t get any decent photos – if I was running early for work, there would be no starlings close by; if there were starlings up close, I was running late.

Then a rather unusual article showed up on my newsfeed.

My encounters with Japanese macaques, or snow monkeys (Macaca fuscata), known locally as nihonzaru (日本猿), have almost entirely been limited to zoos, monkey trainers performing in public, or monkey parks.  I did come across a wild mother and baby around Nikko some years back, but that is it.

The killing of 57 macaques due to genetic impurity – hybridization with the superficially similar rhesus macaque (Macaca mulatta) – has created a minor stir, but I will take a slightly different tack.

Most of the English news contains the same information as the BBC version, so I’ll leave that one here.

Japan zoo kills 57 snow monkeys due to ‘alien genes’

  • 21 February 2017

A zoo in northern Japan has culled 57 of its snow monkeys by lethal injection after discovering they carried the genes of an “invasive alien species”.

Takagoyama Nature Zoo in Chiba said DNA testing showed the monkeys had been crossbred with the rhesus macaque.

The non-indigenous rhesus macaque is banned under Japanese law.

A local official said they had to be killed to protect the native environment.

The zoo’s operator held a memorial service for the snow monkeys’ souls at a nearby Buddhist temple.

Japanese macaques, commonly known as snow monkeys, are native to Japan and are one of the country’s major tourist attractions.

Japan prohibits the possession and transport of invasive species, including crossbreeds.

An official from the Office for Alien Species Management, part of the country’s environment ministry, told local media that the culling was unavoidable because there were fears they might escape and reproduce in the wild.

Junkichi Mima, a spokesman for conservation group WWF Japan told AFP news agency that invasive species cause problems “because they get mixed in with indigenous animals and threaten the natural environment and ecosystem”.

Article ends.

The Huffington Post UK gave some extra information

The zoo housed 164 primates which they believed were all pure Japanese macaques, AFP reports.

But it was later discovered that about one-third had been crossbred and they were culled. It is not clear when the crossbreeding occurred, or if the zoo is at fault.

And this is what I want to know:  Why did the zoo perform DNA tests?  Is it a standard procedure, or did they suspect something?  

Did the hybridization occur in the wild (cue the Lost in Space robot “Danger, danger!”), or did it happen in (gasp!) captivity?  And if the latter, what does that tell us about the laws regarding the possession of invasive species, or about zoo management?

Were the culled hybrids the first generation, or were they second – or even worse – third generation?  

The articles pose more questions than they answer.

A Stroke of Genius…?

Hi blog.

Sometimes I say to myself, “Andrew, you’re a genius.”  And very occasionally, I prove it.

I sometimes get requests for information about various topics, or “Can you identify this?”  Well, I recently received an e-mail from all-round good guy Ian G. “Goat” Fraser:

Okay... maybe.

Okay… maybe.

I instantly recognised the large character at the bottom, kai (界), usually meaning “world”.  I wondered if it was some kind of Buddhist term – one would expect such things on a pilgrim route.  Although on a marker like this the smaller characters would be read top-down, right-to-left, I decided to tackle the three on the left first, simply because I recognised them straight away.  Well, recognised them individually, which is of little help when trying to read unusual vocabulary.

Google to the rescue.  I entered the characters individually – actually, the 々 symbol is like a ditto mark, meaning the previous character is repeated.  As it turns out, 久百々 is read “Kumomo” – a phonetic combination that it hardly likely to be a native Japanese speaker’s first choice.  It is the name of a district within the city of Tosashimizu, Kochi Prefecture.

The set on the right turned out to be more challenging.  First, I used a stroke count application to get the reading for the second character, 岐, ki.  The angle of the photo and the particular writing style made it difficult to pick out straight away.  The first character looked like 六, so I tried searching under the reading “Rokki”, but to no avail.   However, when I tried the search term in conjunction with Kumomo, I got links to Oki no hama.  The first character was actually 大, not 六!!  (A Japanese friend said that she agreed with me as to how the character appeared due to the style of the engraving)

“Of course it says 大岐 久百々 界  What did you think it said?”

A search for Oki gave location just south of Kumomo.  That was when inspiration struck – I recalled the word kyokai (境界) meaning “boundary” or “border” – and tried a map and then street view search of the border between Kumomo and Oki.

From Google street view. That bluff looks familiar...

From Google street view.  That bluff looks familiar…



As it turns out, 界 by itself can also mean the same.

So Ian’s mysterious marker was marking the boundary between the old villages of Kumomo and Oki, which were incorporated into the city of Tosashimizu in 1889.

OK, hardly anything to get excited by – not marking a battle or shipwreck, but I’m nevertheless congratulating myself on a job well done.
