Reasons Why Teuri Island Became a Sanctuary for Seabirds

Teuri Island is a small island with a circumference of about 12 km, and as of 2024, it has a population of approximately 250 people. Despite its size, Teuri Island is considered a “paradise for seabirds,” with an estimated breeding population of around one million birds. Such a sanctuary for seabirds is unique within Japan, as even the neighboring Yagishiri Island, which is about 3 km to the east and of similar size, lacks a significant seabird population.

The reason behind this phenomenon can be attributed to the maritime climate around Teuri Island, particularly during winter when it is influenced by the Siberian high-pressure system from the continent. As a result, the island is continuously exposed to northwestern winds. Over millions of years, these prevailing winds have shaped the landscape, forming cliffs predominantly on one side of the island.

The arrows indicate the direction of the wind. Cliffs were formed on the northwest part of the island where the wind directly hits.

Cliffs, which are among the most challenging terrains for mammals, including humans, become easily accessible for birds capable of flying. Consequently, seabirds, which primarily reside at sea, are not well-adapted to terrestrial life, leading them to choose cliff habitats for breeding where their predators find it difficult to access.

The slaty-backed gull, which breeds on cliffs.

The pelagic cormorant and the black-tailed gull, which breed on cliffs.

The most abundant breeding location for rhinoceros auklets on Teuri Island is on land with soil situated atop the cliffs. Rhinoceros auklets choose to nest on land, despite the presence of many predators, as it becomes harder for predators to spot them during the evening twilight when they return to their nests all at once at sunset. If there were tall trees around the nesting area, they would be at a higher risk of colliding with them in the dark. Therefore, they prefer nesting in areas without tall trees.

Thanks to the island’s strong winds, which prevent the growth of tall trees, Teuri Island provides the ideal conditions for rhinoceros auklets. They have a habitat where approximately 400,000 breeding pairs thrive, making it the world’s No. 1 breeding site for these birds.

Rhinoceros auklets return to their nests by diving into treeless grasslands.

In this way, a miraculous convergence of ideal conditions for seabirds has resulted in the creation of Teuri Island, where numerous seabirds breed. During the seabird breeding season, boat tours are also available, allowing visitors to observe seabirds and geological formations from beneath the cliffs.

The Spectacled Guillemot : A Timeless Favorite among Teuri Island’s Seabirds

 The Spectacled Guillemot: A Timeless Favorite among Teuri Island’s Seabirds

The Spectacled Guillemot, known as “ケイマフリ” (Keimafuri) in Japanese, holds an unwavering popularity on Teuri Island. Its name is derived from the Ainu word “ケマフレ” (Kema-fure), meaning “red-legged.”

True to its name, the Spectacled Guillemot not only possesses red legs but also has a similar crimson color inside its mouth. While observing its courtship behavior on rocky shores, it display its legs while opening its mouth to court potential mates, they leave viewers mesmerized by its stunning beauty.

Compared to other Alcidae birds inhabiting Teuri Island, the Spectacled Guillemot excels at taking off from the water’s surface. It performs a skillful take-off by running on the water while building momentum before finally lifting off. (On the other hand, the other two species, Common Guillemot and Rhinoceros Auklet, perform take-offs by half-swimming and flapping their wings on the water’s surface.)

The sight of “Teuri Blue,” the mesmerizing color of the sea, combined with the radiant red legs of the Spectacled Guillemot, is incredibly beautiful. Many visitors come to Teuri Island solely to witness this enchanting spectacle.

Furthermore, during the latter part of the breeding season, around late June, you can also observe the Spectacled Guillemots carrying food in their beaks to feed their chicks. This heartwarming sight showcases the dedication and care these birds have for their offspring, adding to the enchanting experience of witnessing their behavior on Teuri Island.

The diverse range of prey that the Spectacled Guillemot carries, such as larval fish  and small sculpins, adds to its allure and charm. Observing these graceful birds transporting various types of food is truly captivating.

It’s wonderful to hear that Terasawa Takaki, a photographer residing on Teuri Island, has been so captivated by the charm of the Spectacled Guillemot  that he created a Japanese sake named after them and even adorned his own boat with illustrations of the bird. His passion for these birds is truly inspiring.

I wholeheartedly agree with the invitation for everyone to come and visit Teuri Island to experience the magic of meeting the Spectacled Guillemots in person. It is undoubtedly an unforgettable experience that will leave visitors in awe of the island’s natural beauty and its remarkable avian residents.

The Nocturnal Creatures of Teuri Island (Hokkaido)

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.

Long-eared Owl トラフズク(Torahuzuku)

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.

Japanese tree frog ニホンアマガエル (Nihonamagaeru)

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)

Shiretoko Peninsula: Red Foxes Born at the Fisherman’s Hut (Banya)

We met a family of Red Fox in Rausu during the spring months, when the temperatures had not yet risen to double digits yet.

The three red fox kits lived under the floor of a building called ‘Banya’, which is a hut used by the sea fishermen.

I met these kids when they were less than two weeks old, and they still couldn’t see very well. The parents were frequently grooming them, to remove the dirt from their fur.

After observing them for a few days, I could get to know their daily schedule, and the relationships between the three siblings.

The third kit, which is a little smaller, was often seen dozing off or behaving a little differently then the other two. Every morning, when the time came for the fishermen to return to the port, the parent fox would also go to the port to get the fish from the fishermen.

Every year, from May to June in Rausu, it is not uncommon to find baby foxes coming out suddenly from under the floor of the huts, jump out onto the road, or sadly even get hit by a car in the road. During this season in Eastern Hokkaido, animals such as deer and fox are raising their families, so there is a need to be extra careful when driving.

Seeing the Ryukyu Robin of Okinawa’s Main Island and Amami Oshima

There are two subspecies of the Ryukyu Robin (Akahige in Japanese):
Larvivora komadori komadori which inhabits Amami Oshima Island, and Larvivora komadori namiyei which is found on the main island of Okinawa. These are two species that are considered a subspecies at the moment, but I heard that an announcement to make them two separate species will occur in the near future.
This is a report about a 5 day, 4 night tour conducted in early April.

Day 1   Starts from the main island of Okinawa. First we stop by the Triangle Pond (Sankaku-ike) , a famous birding spot. The usual Eurasian spoonbill (Herasagi) was seen amongst the flock of the usual flock of Black-faced spoonbills (Kurotsura herasagi).

Black-faced spoonbill  Photography by Hiroshi KAWADA

We saw Black-winged Stilts (Seitaka shigi) here and there, and Greenshanks (Aoashi shigi) flying by.  In the distance, Temminick’s sStint (Ojiro tounen) and a Long-toed Stint (Hibari shigi) are present. On the power lines, the Light-vented Bulbul (Shirogashira) and the Jungle Crow (Ryukyu hashibuto garasu, Corvus macrorhynchos connectens) were calling loudly.

From the Triangle Pond, we headed north to the Yanbaru Area. We waited for the Ryukyu robin (Akahige, Larvivora komadori namiyei) and the Okinawa rail (Yanbaru kuina). We could hear the Ashy minivet (Ryukyu sanshoukui,Pericrocotus divaricatus tegimae), and the Warbling white-eye (Ryukyu mejiro, Zosterops japonicus loochooensis), but we did not hear a sound from the target species. The day was completed after confirming the call of the Yanbaru Rail.

 

Day 2. A chilly morning, for Okinawa. We set out in the early morning, before sunrise, to see the Yanbaru Rail. We were able to see two rails crossing the road, as well as 4 Ryukyu wild boar.
After breakfast, we went to Akahige Point. Before I could see anything else, an Okinawa woodpecker (Noguchigera) flew to the dead tree right in front of us! We were so lucky!  It seems like they were nest building, and we could hear the knocking sounds “kon-kon, kon-kon” coming from inside the hole…In order to prevent disturbing them, we kept our distance and observation time short.

The Ryukyu robin was the main attraction, but it didn’t make an appearance for a while. But there was one participant saw a male and female, and even captured some photos of it bathing.

After eating lunch, we went to photograph the Pacific swallow (Ryukyu tsubame), perched along the roadside. Other tourists who saw the scene of us gathered around asking “What is that?” After I answered them, they pulled out their cell phones also and started to snap photos as well! (Lol).

After that, we went to the nearby rice field in search of shorebirds and other waders. Unfortunately, the area had changed so much, that it no longer seemed like a place for the shorebirds to hang out.

In the morning, some people had missed the Red-winged woodpecker and Okinawa woodpecker, so we headed back to that point. Sadly, however, we could not see much and ended up running out of daylight.

 

Day 3    This is the last day of the tour on the main island of Okinawa. However, we did not have much time, so we started from before dawn to look again for the Okinawa Rail. We waited in a certain spot for a long time, but they did not appear there. I did, however see some on the road several times.

After breakfast, we only had one hour. At Akahige Point, we managed to see one individual male. We also got a good look at the Ashy minivet (Ryukyu sanshoukui, Pericrocotus divaricatus tegimae.

We arrived at Naha Airport to head to Amami Oshima. Although it was a little chilly in Yanbaru, it was so hot in Naha! Our plane took off heading to Amami Oshima.

It was windy in Amami Oshima, so we gave up on birdwatching along the coast, and went for a walk through the forest sanctuary instead. While we didn’t have much time there, and the sky looked suspicious as well, we got to see the White-backed Woodpecker (Ooaka gera, Dendrocopos leucotos owstoni).  And we were really hoping to see a  White’s Thrush subspecies, the Amami Thrush (Ootoratsugumi, Zoothera dauma major). However all we saw was the Amami Jay (Rurikakesu), and then we were out of time.

After checking into the hotel and we had finished our dinner, we set out for a nightwalk. Accompanied by a local guide, we drove along the forested roads. As a result, we could see many Amami woodcocks (Amami Yamashigi) and the Amami Rabbits (Amami Kurousagi). Also, we could see endemic species such as the Amami Woodcock, Amami Rabbit, Amami Ishikawa’s frog (Amami Ishikawa gaeru), Okinawa pit viper (Himehabu), and the Amami spiny rat (Amami togenezumi),making it a very special night.

Day 4   We were a bit worried about the weather, but we set out in search of Amami thrush, Amami jay, and other thrushes. Unfortunately, we had a little rain, on and off. We broke the participants up into two search groups, one for searching for the Ryukyu robin, and one searching for the Amami thrush. The Ryukyu robin group could end up seeing a few. The Ryukyu thrush group, could see one, but no one could catch a photo of it.
Then, after lunch, we split up into two groups again, and we were all able to see the target species and get photos of them both, fortunately. We also had some good opportunities to photograph the Ryukyu jay.

Day 5    Last day of the tour. The weather forecast is not looking good. Unfortunately it looks like rain until the end of the tour.

First, we set off before dawn to listen to the calls of the Ryukyu thrush. On the way, we saw an Amami woodcock and heard the calls of a Ryukyu scops owl. As we parked the car, we had a light rain, but we could hear the calls of the Ryukyu thrush.

After breakfast, we didn’t have much time. But it would have been nice just to see the White-backed woodpecker (Austin Ooakagera), so we searched for it on the way to the airport, but we could not spot it. Finally, we went to a rice paddy, where some migratory birds, might be around. Despite the rain, we were able to see the White-Breasted Waterhen (Shirohara kuina) and the White Wagtail (Houjiro hakusekirei, Motacilla alba leucopsis), the Black-winged Stilt (Seitaka shigi) and other species.

This tour was a hyper-focused tour just for the hardcore birders, with the aim of seeing both subspecies of the Ryukyu robin on the main island of Okinawa and on Amami Oshima, and I can say it was a success. I wish to thank all the participants, who made the most of their precious time, over the course of 5 days, to intensely help search for birds, from early morning until late at night.

Ezo Chipmunks Preparing for Winter

You might have a chance to encounter the small animals in the parks and shrines while vising the Eastern Hokkaido area.

Among them are the chipmunks, which hibernate through the winter. They will use the entire park in the autumn months to collect food for their winter storage. They may carry many kinds of food back to their nests such as yew nuts, walnuts, acorns, and mushrooms.

The Ezo Chipmunk, Tamias sibiricus lineatus, is a subspecies of chipmunk that is distributed throughout Hokkaido, its surrounding islands, and the islands of the Northern Territories.

Its body is about 15 centimeters long, a similar size as a mouse; and its footsteps are hard to hear, so it is often not noticed. Hokkaido is home to two small species: the Ezo squirrels and the Ezo chipmunks. The biggest difference is that Ezo chipmunks hibernate, but Ezo squirrels do not hibernate.

Ezo squirrels build their nests at the tops of tall trees, and basically live in the canopy. Ezo chipmunks, on the other hand, build burrows at the base of trees and hibernate, so their home range is largely on the ground level.

Ezo squirrels are also longer than Ezo chipmunks, with the squirrel’s tail alone, measuring about 15 centimeters.

Ezo squirrels can be observed throughout the year, but the Ezo chipmunks are easier to find from September to October, which is the busy pre-hibernation feeding season for them.

Common Guillemot observation update 2023

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.

White Orca (Shiretoko, Hokkaido)

In May 2023, a ‘white killer whale’ appeared in the Nemuro Strait after two years of absence.

White orca / killer whale at Shiretoko, Hokkaiado 白いシャチ

The contrasting color of black and white is a characteristic of killer whales. But this orca’s entire body is white, so the eyepatch and saddle patch are not visible unless you look closely.

After the first observation of two of them separately in the Nemuro Strait in 2019, two white killer whales swimming together made headlines in 2021. And after two years, this year (2023), one white killer whale was seen off Rausu Port.

According to a Japanese news website, he is a “mature male”, “nearly seven metres long by eye measurement”, “at least nearly 50 years old” and “most likely the same individual as the first white killer whale identified in Japan”.

It is not known whether it is an albino (Albinism), which cannot produce melanin due to a genetic abnormality, or a white variant (Leucism) due to mutation. It looks like a white variant because it does not have the characteristic red eyes of an albino and its body colour is greyish.

Pod of 13 killer whales. The colour white is said to be a disadvantage in the race for survival, as it is easily noticeable in nature, but this individual has been able to grow well.

All boats are busy with the rare appearance of ‘white Orca’.

The key highlights for three most popular sea birds on Teuri Island (Spectacled Guillemot, Common Guillemot and Rhinoceros Guillemot)

We have summarized the features of three species of birds in the Auk family that are popular amongst birders visiting Teuri Island: Spectacled Guillemot, Common Guillemot and Rhinoceros Auklet!

(1) Carrying caught fish with their beaks.

The main part of the observation is watching birds bringing fish into their beaks to feed their chicks. This is a common feature of the Auk family, as they are able to swallow fish while swimming in the water and cannot spit out the fish once swallowed to feed the chicks. Hence they fly with several fish in their beak to bring the catch back to the nest.
On Teuri Island, night tours are held every evening during the season (from end of April to the end of July) to observe the 800,000 Rhinoceros Auklets returning to their nests in the evening.

Common Guillemot flies with fish in its beak.

Unlike many other species, Rhinoceros Auklet feed their chicks only once a day, when they finally return home in the evening. Therefore, there are several fish for them to bring into their beaks!

 

(2) Their wings are short and they need to run on the surface of the sea to fly away

When diving in the sea, the Auk family swim by flapping their wings underwater. For this reason, their wings are shorter and smaller than those of other birds of the same size, so that they do not create resistance in the water.

Spectacled Guillemot’s wings

The size of a Rhinoceros Auklet’s wings clearly differs when compared to the size of a Black-tailed gull’s wings.

Due to smaller wings, the Auk family birds do not have high flight capabilities and flap their wings more frequently in the air than bird species of the same size. They also need to run on the surface of the sea to gain momentum in order to take off from the sea into air.

Among the most beautiful is the red-footed Spectacled Guillemot, which runs along the surface of the sea. You can only see this view up close from aboard a small seabird-viewing boat. Please come and see this beautiful moment when you visit Teuri Island!
