Many visitors come to Teuri Island in June to see the “Rhinoceros Auklet return to their nests,” but the breeding season begins in March. It is difficult to visit the Rhinoceros Auklet breeding grounds because there is still snow on the ground at that time, but here are some scenes from a visit in April.
In late April, Rhinoceros Auklet nests were visible in the breeding area because the Giant knotweed had just sprouted. Therefore, it was possible to observe the Rhinoceros Auklet as they landed and entered their burrows when they return. Rhinoceros Auklet at this time of the year are incubating their eggs, so the return at night is for the parent birds to “take turns”. The parent bird that has been out at sea returns in the dark, and the other parent bird that has been holding the eggs all day goes out to sea for feeding. For this reason, the number of Rhinoceros Auklets seen during this period is less than during the chick-rearing period, but this is the only time of year when one can watch them slowly entering and leaving their nest holes before the Giant Knotweed covers them up. Moreover, as soon as the buds begin to sprout, the Giant knotweed grows day by day and covers the nest in no time at all.
We will wait for Rhinoceros Auklet to return to their nests while viewing the evening scenery at the Red Rock Lookout.
This is a Rhinoceros Auklet nesting site. The Giant knotweed appears to have been cut off at a certain height, which indicates the height of the snow cover that winter. Only the part that was buried in the snow remains, and the part that came out of the snow is gone due to the harsh winds. Thanks to this, Rhinoceros Auklet’s burrow is still clearly visible.
It was the night of the full moon. The full moon was very beautiful in the clear air of Teuri Island.
The moonlight created a “path of light” in the sea.
Rhinoceros Auklets have begun to return to their nests.
Rhinoceros Auklet may be watching us for a while after landing, but they do not immediately head for the nest hole. When the chicks are born, the parents return with food in their mouths and rush into the nest hole, so there is no time to observe them slowly. The chicks are hungry, and Rhinoceros Auklets that could not get any other food may take it away from them. So this is the one of the best time to observe them.
One individual whose nest hole was close to our observation area on the road was watching us and approaching us. Since the nest was under the road at our feet, it ran into the burrow at a high speed from the halfway point.
Some Rhinoceros Auklets do not enter their burrows immediately, but take their time.
If this is your second visit to Teuri Island, this is also a great time to visit. This is also the season when, if you are lucky, you may encounter “Herring Spawning” and migratory birds!

Watarase-yusuichi is the largest detention basin in Japan, covering an area of 33 square kilometers. It is a vast expanse of reed beds, lakes, marshes, and riverside forests. 1,000 species of plants, 260 species of birds, 1,700 species of insects, and 50 species of fish have been recorded. Because of this rich biota, the area has been designated as a registered wetland under the Ramsar Convention.
One of the Best Raptor Wintering Grounds in Japan
Twenty-five species of eagles and hawks have been recorded so far, especially in winter, and the area is one of the best wintering grounds in Japan—especially for the eastern marsh harrier. Several species of owls can also be seen here.
Eastern Marsh Harrier
Although they are resident birds, their numbers increase every winterdue to migration. They can be seen in reed beds and nearby rice fields, and return to their roosts in the floodplain at sunset.
Hen Harrier
A winter bird, it can be seen in reed beds and nearby rice fields, returning to its roost in the playground at sunset. They are few in number.
Eastern Buzzard
They are resident birds, but their numbers increase every winter due to migration from the mountains. The most common species, along with the kite.
Eurasian Goshawk
A resident bird, it can be seen flying in a variety of environments from forests to reed beds.
Osprey
A resident bird, here only in winter, it can be seen above the lake water and in the surrounding trees.
Peregrine Falcon
A resident bird, here only in winter, it can be seen in reed beds and nearby rice fields.
Common Kestrel
Although they are resident birds, their numbers increase every winter due to migration from the mountains. They can be seen in reed beds and nearby rice paddies.
Merlin
A winter bird, found in reed beds and nearby rice fields. Few in number.
Short-eared Owl
A winter bird, it can be seen in reed beds at sunset. However, the location where they can be seen varies, as they are natural enemies of the tundra-winged teal.
Long-eared Owl
A resident bird, it is found here in the riparian forests in winter and spring. They breed in the spring and migrate after leaving the nest.
Waterfowl Seen in Reed Beds and Lakes
Watarase Yusui is one of the few breeding grounds for the Oriental Stork, a globally endangered species, and other rare species can also be seen here, including the taiga bean goose, tundra swan, and Eurasian bittern. In winter, numerous ducks, herons, and snipes can be seen, but only the rarer species are shown here.
Oriental Stork
A resident bird, several pairs successfully molt annually. Found near the water’s edge of lakes and marshes.
Falcated Duck
A beautiful winter duck, found in lakes and marshes.

On April 15, 2024, the first herring spawn in 70 years was observed on Teuri Island, Hokkaido. The islanders were excited to photograph and then harvest the herring. At an island inn, stewed herring and herring roe were served. No one on the island today knows what it was like in the heyday of the herring harvest.
Here is some of the wildlife we observed on Teuri Island in the spring.
On the route from Haboro Port to Teuri Island, black-throated divers (surprisingly common), ancient murrelets, rhinoceros auklets, and spectacled guillemots were seen.
Eight species of seabirds breed on Teuri Island: the common guillemot, spectacled guillemot, rhinoceros auklet, black-tailed gull, slaty-backed gull, Japanese cormorant (Temminck’s cormorant), pelagic cormorant, and ancient murrelet. By April, they have already begun their breeding season.
Black-tailed gulls are breeding and expanding their territory on the Kurosaki coast, and around April 20, mating (or pseudo-mating) has already started taking place throughout the area.
When I looked at the Japanese cormorant breeding site from the seabird observation hut, they were already feeding their chicks. The Japanese cormorant is a seabird that starts breeding early, and it seems to be getting even earlier. Slaty-backed gulls were breeding and mating on the upper slope of the bluff. There were many rhinoceros auklet nesting sites in this area as well.
Red-breasted mergansers are seen near Maehama Fishing Port. Red-breasted mergansers migrate to Teuri Island as winter visitors. They will soon be heading north as well.
And then there are the harlequin ducks. They are the most common ducks on Teuri Island. I often saw them near Maehama Fishing Port and Lombaba Beach. Harlequin ducks can be seen all year round on Teuri Island, but they are definitely easier to see—and more beautiful—during the winter months.
On one morning when the wind had calmed a bit, we went out to the sea on the Keimafuri-Gou, a small boat operated by island photographer Takaki Terasawa. The view from the boat was that of Teuri Island in spring!
A steller sea lion we met as soon as we left the harbor. They migrate to Hokkaido from the Kuril Islands in winter. This young male was all alone. Teuri Island, where herring now spawn, attracts wildlife as well as people. It is a symbol of the richness of the sea.
From the boat, we observed the black-tailed gull breeding grounds on the Kurosaki coast and then headed in the direction of Akaiwa. We did not see any common guillemots at the breeding site, but we did see four common guillemots flying over the sea in the vicinity.
The reef was teeming with some very dry and fluffy spotted seals.
The beautiful sound of spectacled guillemots chirping at each other echoes out to sea. On a rocky shore, an adorable pair is seen in a courtship gesture.
Lastly, please take a look at this herring spawn, photographed on April 15 by the staff of Saiyu Travel’s Teuri Office (Teuri Island Naturelive).
Spawning occurs in spring, when females lay their eggs on seaweed in shallow waters less than one meter deep, and males release sperm to fertilize the eggs. This spawning causes the seawater to become white and murky.
A herring dish served at the Yorozuya Ryokan( 萬谷旅館)where I stayed. The fresh herring was so tasty.
I myself had just returned from a trip to Sitka, Alaska, in search of the wildlife that gathers there during the herring spawn. In Alaska, the “Herring Run” is a very popular wildlife tour where you can encounter humpback whales, gray whales, bald eagles, steller sea lions, and other creatures that congregate in the waters of Sitka.
Will Japan’s herring spawn one day be referred to as Hokkaido’s “Herring Run”? Before that, it is important to first restore the richness of the sea where herring come to spawn every year. I sincerely hope that the herring will return next year too.

Observation: April 2024, Teuri Island, Hokkaido
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.

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.
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.
There are two subspecies of the Ryukyu Robin (Akahige in Japanese): Larvivora komadori komadoriwhich 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).
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.

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.

Observation : May-Jul 2023, Teuri Island, Hokkaido
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.
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.
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!

There were two tours conducted in December 2022. This is the first tour report that took place Dec 12-16, 2022. Reported by bird guide, Yoshinori Toshitake.
Day 1
We gathered at Kagoshima Airport and headed to Izumi by private car. We arrived at Izumi in the afternoon and started looking for the cranes. First, I saw the Sandhill Cranes, but it was far away on this day, so I decided to look for the Common Crane and a Siberian Crane, while of course observing and photographing the White-naped Cranes and the Hooded Cranes.
Day 2
We arrived at the reclaimed land while it was still dark, and first observed the sunrise and cranes. The cranes flying in against the backdrop of the sunrise was beautiful, and the participants were engrossed in getting their photos of the scene.
After the sunrise, I was aiming to see the Daurian Jackdaw, which was perched on the electric wires. On this day, I could see the white-colored one, known as “Shiromaru.”
After that, while I was watching cranes from the roof of the Observation Center, I found some Black Cranes hiding in the shadows of the road. I waited patiently, moved to a position where I might see the whole body of the cranes without the other cranes blocking it. This year, the number of cranes is a bit less than normal, but it is all a matter of timing if you can see them or not.
While I was waiting for this crane to come out from the flock, a Perigrine Falcon also appeared, and the ducks that were foraging in the farmland got pretty riled up by it.
Then, we tool a walk along the river, where we aimed to find the European Peduline Tit and the Chestnut-eared Bunting. We could first, hear the calls of the tit, out on the reed bed, but they appeared pretty close by eventually. It is a very small bird, but it didn’t sing at all while observing it, so it took quite a while for everyone to be able to spot it.
The Chestnut-eared Buntings were perched on the concrete embankment, and an Osprey was observed bathing in the river. Ospreys are often only seen in flight, so it is quite rare to see them in the water.
In the afternoon, we went into the mountains and looked at the dam and along mountain streams. The Mandarin Duck were still very cautiously avoiding us, and the Mallards, Eurasian Wigeons, and Common Pochards were seen in the water near the dam. While I was scanning for Mandarin Ducks in the darker areas of the edges of the water, I saw a Mountainhawk Eagle gliding, for just a moment. And as I approached the area of the Crested Kingfisher, I found one perched on some driftwood. The kingfisher flew away and then landed on a dead tree, so I tried to put it in the scope while informing everyone, but it flew off again immediately. Also, on the way back, when crossing the bridge, I heard the call and saw the flight of the kingfisher. Surprisingly, there were two that flew together in the upstream direction of the river. In the evening, we returned to the reclaimed land and observed Eurasian Spoonbills and Northern Lapwing.
Day 3
We arrived at the reclaimed land while it was still dark, but unfortunately the clouds were so thick that we could not see the sunrise or the moon. I was waiting in the car, regretfully thinking that it would be useless to try to observe anything, but a Siberian Crane appeared. The Siberian Crane was easy to observe last year, but it was rare to see them this year.
We left Izumi early to catch the ferry before noon and headed to Kumamoto. The ferry heading to Shimabara was bustling with the Black-headed Gulls looking for snacks from the passengers even before our departure. I don’t know how many there were, but after the ship left the port, many of them continued to follow the ship.
After leaving the port, we observed a large flock of Brown Boobies resting on the embankment, and that day, there were also some flying near our ship.
The Isahaya Reclaimed Land has vast cultivated farmlands and reed beds. In the field of reeds, there were various species we observed, such as the Hen Harrier and Common Reed Bunting. The Common Starling and Common Kestrel were seen and photographed in the farmland areas.
Day 4
In the morning, we visited the Isahaya reclaimed land again. Birds of prey such as the Common Kestrel and Common Buzzard can be seen around the reed bed. The Merlin was also observed targeting hunting the small birds on the edge of the grass.
In the afternoon, we moved to Higashiyoka in Saga Prefecture, and observed the mud flats at high tide. On this day, the tide level was much lower than normal even, though it was high tide, and the mud flats were dotted with shorebirds, Common Shelducks, Saunder’s Gulls, and other species of birds.
On the way from the mud flats back to the hotel, we found a magpie, which I rarely see anymore. It was observed perched on a powerline, and then on the roofs of the houses.
Day 5
Since we saw the magpie yesterday, I changed the plan and headed to the reservoir first instead. We could see the thousands of Bikal Teal, very alive and well, and the large flocks of them were spread across the open water.
Here, we took a walk on a paved road, less than 3km, and enjoyed watching the large flocks of Baikal Teal, as well as being able to see birds of prey, such as the Northern Goshawk and smaller birds, such as the Common Reed Bunting. After that, we went up the river and observed Common Kingfisher, Long-billed Plover, Brown Dipper, etc. in the stream with clear water. Then we headed to Fukuoka Airport, and ended our tour there.
