Birds of Eastern Hokkaido in Winter

During this winter, we were able to observe many birds, including red-crowned cranes and Ezo Ural owls. The number of photographers from abroad has also increased considerably—especially in Tsurui Village, where red-crowned cranes can be seen. Over 200 people gathered on the Otowa Bridge to photograph the birds sleeping in the river.

Near the Otowa Bridge, from January to early March, temperatures drop below -15°C, and on humid days, a phenomenon known as “Steam Fog” in which steam rises from the river, can be observed. The white breath of the red-crowned cranes as they chirp at each other is beautiful, and the large snowflakes that fall create a magical scene.

Ezo Ural owls are usually found in the trees they’ve chosen for their fixed nest sites, but they may change their location from year to year. We speculate that this may be due to changes—precipitated by the amount of snowfall in a given year—in their rodent-hunting spots. In the month of February, at the nests we observe every year, we can see the owls stand side by side in pairs—for them, this is courtship season. In some nests, we could not see the pair line up together, perhaps because one of the two had disappeared.

The long-tailed tit is the most popular wild bird in Hokkaido nowadays. In winter, they look like snowmen when viewed from the front, puffing up their feathers to ward off the cold.

Long-tailed tits are only about the size of a ping-pong ball and usually hang from branches at the top of trees, pecking at insects and winter buds. If you are lucky, they will come down to a lower branch to catch their food, and you may even be able to photograph them at eye level.

Food is scarcest from February to March, and in addition to the food they normally eat, they strive to eat really small plant seeds to sustain themselves.

In April, insects appear, ensuring that the long-tailed tit will be well nourished. By May, we can expect to see new chicks.

Red-crowned cranes, Ezo Ural owls, and long-tailed tits are all difficult to observe from mid-March onward, as their activity patterns change dramatically for the breeding season.
Mid-February, when they are actively courting, is the best time to observe these three species.

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 red lines indicate the original location 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.

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.

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!

Seabirds breeding on Teuri Island (Hokkaido)

Common murre, Common guillemot　Uria aalge 

Common Murre or Common Guillemot has a distinctive penguin-like appearance due to its legs positioned at the back of its body. In Japan, they breed only in one place, a cliff cave near the red rocks on Teuri Island. The breeding site of the cave can only be observed from the boat, but they can sometimes be seen floating above the sea from the Akaiwa Observatory. In 2002 their numbers were reduced to 13, but now(2023) exceed 100 and is steadily increasing.

Spectacled guillemot 　Cepphus carbo 

Spectacled Guillemots, with their very cute red legs and red mouth, breed in the crevices of the cliffs that stretch from south-west to north of Teuri Island. The moment when the Spectacled Guillemot takes off after running on the surface of the water is one of the most beautiful moments, when the colour of the sea, known as ‘Teuri Blue‘ and the bright red legs of the Spectacled Guillemot shine brightly. Take chance to watch it up close from a small seabird-watching boat that run s early in the morning (reservation is a must).

 Rhinoceros auklet　 Cerorhinca monocerata 

As its name suggests, Rhinoceros Auklet has a rhinoceros horn-like projection that appears during the breeding season from April to July. It is said that there are currently 800,000-1,000,000 rhinoceros breeding on Teuri Island, and the sight of them all returning to their nests at dusk is the one to behold. Because they dig holes in the ground to build their nests, which is quite unusual for bird species, photographers can observe them relatively closely when they return home.

Ancient murrelet　 Synthliboramphus antiquus 

On Teuri Island, they are seen every year from late May to early June. Several birds form groups up to 10 birds and feed on zooplankton and other organisms. Because they are very small and frequently dive, it is very difficult to observe them on days with high wave swell. It is said that they breed only on Teuri Island in Japan – take the rare chance to capture them here.

Pelagic Cormorant　 Phalacrocorax pelagicus

This cormorant normally lives in the open sea. During the breeding season when they come to Teuri Island, their entire bodies are covered with a amazingly beautiful sheen, and the base of its beak is stained red. They can build their nests in small bumps and hollows in cliffs, using saliva and mud to harden very fine nesting material, so natural enemies such as mammals cannot approach their nests.

Japanese cormorant　 Phalacrocorax capillatus 

A species of cormorant widespread across Japan. During the breeding season, its head turns white. Cormorants hunt deep underwater where visibility is poor, so they have blue eyes that are easy to see when viewing in the dark. They have a low oil content on their body surface to facilitate swimming easily underwater, and can be observed spreading their wings on rocks to dry their bodies after swimming.

Black-tailed gull　 Larus crassirostris

This species of gull is characterised by its yellow legs and tail with a black band. On Teuri Island, their numbers have increased dramatically in recent years, with the estimated number of nests doubling from two years ago in 2021 to around 5,000 now in 2023. Kurosaki Beach (literally “Black-cape beach” in Japanese), a major breeding ground for Black-tailed gulls, is often called ‘Shirasaki Beach (“White-cape beach”)’ because its black rocks have turned completely white from their excrements.

Slaty-backed gull    Larus schistisagus 

A large gull with pink legs and a bright white tail. It reigns at the top of the biological pyramid on Teuri Island, and will swallow an adult Rhinoceros Auklet up to 38 cm long awhole. Black-tailed gull chicks, pit vipers and sea urchins are other favorites. If you see sea urchin shells lying around town, they are often the remains of the Slaty-backed gull’s meal.
