The Nocturnal Creatures of Teuri Island (Hokkaido）

>For information and tours of Teuri Island, click here!

Teuri Island is located at 44 degrees north latitude, so during the period from spring to summer, the daylight hours are long, and the sky becomes completely dark around 21:00 (9:00 PM). In the morning, it starts to get bright around 3:00 AM, which means that the nocturnal creatures are spending super busy throughout the night.

Speaking of nocturnal creatures, one  cannot fail to mention the owl family. In the year 2023, the breeding of the Long-eared Owl (トラフズク Torahuzuku in Japanese) has been confirmed on the island.

During the early spring, we confirmed the presence of three chicks, but from the first half of July onwards, we could only find two. It is suspected that one of them might have died at some point. This experience made us realize the true harshness of nature.

Furthermore, the Kiwi of Japan is called a “ヤマシギ” (Yamashigi), which refers to the Eurasian Woodcock, also inhabits Teuri Island.

The life style of the Eurasian Woodcock is similar to the Kiwi of New Zealand, it is a nocturnal creature and preys on worms and other creatures found near the ground. However, the Eurasian Woodcock has the advantage of being able to fly, which allows it to have a broader range of habitats. It has numerous holes in its beak with nerve endings, enabling it to sense movements and detect prey while inserting its beak into the ground.

Additionally, on warm nights, the only snake species found on Teuri Island, the Japanese Mamushi Viper (マムシ: Mamushi,  also known as the Japanese pit viper), also becomes more active.

The snake, often referred to as a nocturnal creature, on Teuri Island, might also be quite active during daytime, especially in the cooler seasons like early spring. Despite being a reptile, it gives birth to live offspring instead of laying eggs. This adaptation might be what allowed it to efficiently reproduce in the fluctuating temperatures of Teuri Island, making it the only snake species on the island.

The Japanese Mamushi Viper is the most well-known venomous snake in Japan. The image of “Mamushi = danger” is deeply ingrained, and this might be a reason why drivers tend to be less aware of avoiding them compared to other creatures. As a result, during the season, I witnessed numerous instances where these vipers were hit and killed by vehicles.

Also, the Japanese tree frog (ニホンアマガエル  Nihonamagaeru), the only amphibian species found on Teuri Island, becomes active during the night.

Due to its small size, approximately 12km in circumference, Teuri Island has limited sources of stable freshwater, making it challenging for amphibians, which constantly require water, to find suitable habitats. However, despite the scarcity of such environments, numerous individuals of the Japanese tree frog  can be found breeding near locations such as rainwater accumulated in abandoned ships and in small springs close to the coastline.

Furthermore, after observing the nocturnal activities, one can enjoy the breathtaking sight of a beautiful starry sky. On clear nights, shooting stars can be observed almost without fail.

When you visit Teuri Island, please make sure to look up at the night sky before you leave.

Mt. Fuji in the Summer! Observing Subalpine birds at Okuniwa and the White-bellied green-pigeon on the Oiso Coast

Reported by YOSHINARI TOSHITAKE for a tour conducted from August 21 – 23.

Day 1

Meeting at the Shinjuku bus terminal and took a bus to the 5th station of Mt. Fuji, which is approximately 2,300 meters above sea level.

When we arrived at Okuniwaso as planned, we immediately started observing birds and taking photos. The back garden is short and has a well-developed walking path, so one of the attractions is that you can stroll around freely.

The waterhole

At the waterhole, we saw Eurasian bullfinch, Red-flanked bluetail, Coal tit, Goldcrest, Japanese leaf warbler. The birds are less than 10 meters away, so we could get good pictures. The little birds came out here and there, so I over heard the group talking about how they were satisfied with the afternoon.

Okuniwaso is a mountain hut, so there are no baths or showers (the temperature is cool so no sweating, but it gets really chilly in the mornings and evenings.) Dinner is served early (when it was still light!) at 4:30pm, but the food was luxurious for being at a mountain hut.

Plentiful Dinner at the Mountain Hut

It was still light even after dinner, so the owner of Okuniwaso showed us the walking path. Unfortunately, the clouds in the western sky were too thick to color Mt. Fuji red in the sunset, but we were able to see the peak of Mt. Fuji up close. And at night, we could see the stars in the sky, between the clouds. Smartphones these days are so advanced, it’s was easy to take pictures of the starry sky. Both of the following images were taken with an iPhone.

Day 2

It was clear skies at dawn, so we were able to have a great view of the sunrise over the ridge with Mt. Fuji.

Daybreak

Just like yesterday, the birds came out frequently for us on this day, as well. A male ed-flanked bluetail that hadn’t come out yesterday also showed up, but perhaps it was in fact, that there were three different males. The male ed-flanked bluetail is truly beautiful.

We enjoyed ourselves at Okuniwaso in the morning hours, and after lunch, headed towards Oiso in preparation for observing green pigeons the next day.

Day 3

Unfortunately, today’s weather forecast is cloudy and rainy. Despite the bad weather, we left the hotel with the hopes that it will improve, while it was still dark, and arrived at Oiso and Terugasaki Beach. It was raining a little when we arrived, but the rain gradually subsided and fortunately, it became sunny. White-bellied green pigeons were flying in, but they were quite wary and would not come down to the rocks. Also, it seemed to be raining quite a bit on the mountain in the direction from which they flew in. However, they gradually started descending to the rocks, and we were able to observe them drinking seawater.

When the green pigeons that had been drinking seawater, took off all at once, a young peregrine falcon appeared. I didn’t see any attacks on the green pigeons, but it seems like the falcon had been hiding somewhere close by.

I was a bit worried about the rain forecast for our last day, but considering that last year it was sunny and quite hot, it ended up being a good day, which was a relief. During the tour, we had an interesting combination of subalpine birds at an altitude of 2,300 m and the White-bellied green pigeons on the coast, and we could see a wide variety of birds this year.

(Total of 27 Bird Species）

Common Guillemot observation update 2023

>For information and tours of Teuri Island, click here!

Teuri Island is the only breeding site of the Common Guillemot in Japan.
At one time the birds’ population was reduced to 13 birds, but their numbers are now recovering.

This year again, Common Guillemots are seen bringing food back to the nest. Bringing food back to the nest means that chicks are born, and the circle of life continues for these species, which is a very comforting thing to know! The first confirmation was made on 8th of July, so it seems that the Common Guillemot’s breeding season is the same as in previous years.

A project was underway on Teuri Island to use decoys to entice them back to the island due to a decline in their population.

This year, the caves that have been used as breeding grounds have become very cramped with decoys and real Common Guillemots, like a crowded train in Tokyo.

This may be why Common Guillemots have been frequently seen perched on rocks other than the breeding caves since the beginning of July this year.

Pelagic Cormorants also breed on this rocky area and congregate in large numbers in the adjacent hollows. This spot is not visible from land, and can only be observed from a seabird watching boat.

Observation of Common Guillemots went well, as they have been seen flying in groups and floating in the sea in numbers of up to 50.

The Common Guillemot population, which was reduced to 13 birds in 2002, has been steadily increasing and now exceeds 100 birds. However, there is only one breeding site in Teuri Island so far and no increase in breeding sites has been confirmed, so we hope that the number of breeding sites will increase next time, as there is concern that the population may plummet if there is only one site and natural enemies appear.

Shakotan’s Undersea Columnar Joints and Hokkaido’s Marine Life

By car from Sapporo, the Shakotan Sea is 1 hour and 30 minutes by car. The scenic spot called the “Shakotan Blue” is famous for the high transparency of the water. The columnar joint formations look like underwater ruins, which are very famous.

Columnar formations are polygonal columnar fissures caused by volumetric contraction as the magma solidifies and then cools. It is a manifestation of the Pacific “Ring of Fire,” also known as the “volcanic archipelago.”

Looking up at the sea’s surface from the columnar joints.

This point of the columnar joint is called the “hidden root of Biyano.” The depth here is about 25 meters, and it is too bad that it’s barely visible from the glass bottom boat.

Heading towards the sites along the coastline. Diving the strait was blessed with good weather. When I visited in September, there wasn’t much marine life to see then…but I was able to see wonderful “Hokkaido’s sea creatures on the Sea of Japan side” with wonderful guides.

Far Eastern Shrimp Pandalus prensor Stimpson. Beautiful blue speckles. If eating it raw, it tastes like sweet pink shrimp.

Common Sunstar Crossaster papposus. There are many legs, just like sunrays.

When you take a macro shot, it looks like a flower garden.

The coastal area’s rock walls which are carved by the waves, are a treasure trove for macro photography.

The kelp was a bit wilted, but the coral and kelp were beautiful.

Unfortunately, I could not eat the sea urchin because fishing was prohibited from August 31st. I decided to revisit Shakotan again in the future.

Wildlife Sightings for January in Eastern Hokkaido

February is generally the peak season in Hokkaido’s eastern region, but what is it like in January? In this blog, we would like to introduce the wildlife that you might see in East Hokkaido (Kushiro, Notsuke Pennisula, Rausu) in January.

Short-Eared Owl (Notsuke Peninsula)

During this period, short-eared owls migrating from Siberia and other places, could be observed (depending on the year). This grassland owl is a rarity in Japan, but when you visit the open grassy fields in the evening, you might observe them flying around looking for mice. After that, as the weather gets colder, many of the owls migrate to other places around the main island of Japan (Honshu), so Hokkaido in January might be the best time to photograph the snowy landscapes with short-eared owls.

Ural Owl (Eastern Hokkaido)

The ural owl, is an endemic species that inhabits Hokkaido as a resident year around. It is easy to spot these birds in the leafless trees.

Blakiston’s Fish Owl (Rausu)

The Blakiston’s fish owl can be seen from a facility along the Chitorai River in Rausu. It is a very rare species that inhabits only eastern Hokkaido and Far East Russia (Kunashir Island).

White-Tailed Eagle (Rausu, Notsuke Peninsula, Nemuro)

In eastern Hokkaido, there are wildlife that migrate here to overwinter, and there are also resident birds as well. They are most abundant in February, and can be easily seen flying around Lake Furen and Rausu.

Steller’s Sea Eagle (Rausu, Notsuke Peninsula, Nemuro)

The Steller’s sea eagles, which breed in Far East Russia such as in the Kamchatka Peninsula, migrate to eastern Hokkaido in the winter. February is the most common, month they start arriving, but I was able to confirm their appearance in January as well.

Red Crowned Crane (Tsurui Village)

In January, the red-crowned cranes are preparing for the breeding season. I was able to see the paired couples singing and dancing together, and a young bird practicing alone. From February to March, the breeding season is in full swing, the number of couples increase and the time they spend doing their displays goes on for longer periods of time.

Red Fox

The red fox, a subspecies that inhabits the Sakhalin, Hokkaido and its surroundings, is also approaching their breeding season as well. During this period, males will walk large areas in the deep snow searching for females, so the muscles of the upper body are said to be very developed, and this one here is a good example, showing very developed pectoral muscles.

One fox approached us with the Kunashir Island in the backdrop, and if you look closely at its tail, you can see some small hair loss. Scabies is spreading among the red foxes, and is seems to be causing a population decline.

Ezo Sika Deer

These are some Ezo Sika Deer with the Kunashir Islands in the background. At this time of year, they have winter fur and are very cute, but they have a voracious appetite and are highly successful at reproduction, so in some areas they are being exterminated due to damage to agricultural areas. At Shiretoko Sarai, the venison is added to the menu so it is not wasted.

In addition, you might see kestrel and a group of long-tailed tit.

January was a fulfilling time to encounter wildlife in eastern Hokkaido for a 3 nights and 4 days stay in January.

Raising The Next Generation of Blakiston’s Fish Owl; Observed in Rausu

Two chicks were born in 2022

Usually, the Blakiston’s fish owls will mate in February and lay two eggs in March. The female warms them for 35 consecutive days, without rest. However, for the Blakiston’s fish owls it is very challenging with various factors influencing the results: like the extreme weather and cold temperatures during breeding; the physical condition of each owl itself; and their past experience of raising chicks. On average only one bird survives until fledging.

At the Blakiston’s fish owl Observatory in Rausu (Washinoyado), the birds can be observed throughout the year, and in June 2022, the pair were able to fledge both chicks for the first time in 15 years! The young birds practiced flying near their nest, and then eventually around August, they would come down to the river with their parents to learn how to catch the fish. Around September, they learned how to hunt for themselves, becoming more independent.

Sometimes, there are young birds that cannot fish successfully, and end up on the roadsides to try to eat roadkill. However, they might end up getting hit by cars due to the dark conditions. Thankfully, our two chicks at the Observatory have been safe from this kind of accident so far.

One of the chicks born in 2022

In December, the two will become independent, and then around 2024 they will mature and find their own partners and live somewhere in Shiretoko. I am praying that they can both survive the trials of winter to live long lives.

Brown Bears Awaiting The Salmon Run On Shiretoko Peninsula

The fall of 2022 was a rough start to the winter for the bears. The pink salmon, which usually go upstream starting from mid-August every year, provide an important source of fat and nutrients for the bears to survive the winter. But this time, there were almost no salmon that came.

In 2021 was said to be bad with 1/10 the number of salmon compared to the year before. But this year was even more horribly below that. We rarely observed the brown bears in August this year, even though normally we would see them, if we took a boat along the coast. It was thought that the shortage of food would continue, but in September, the chum salmon returned in numbers that were close to the previous years’ numbers.

The bears which had returned to the forests due to the lack of salmon, came back to the shorelines in September to look for returning salmon. Due to the short period of time, and fierce competition, it was quite difficult for the mother bears with cubs and the younger, weaker bears to get close enough to the beach to catch the salmon. In only a month’s time, the long, harsh winter of Shiretoko will begin.

I hope they can get through the winter, and we can see them again next year.
