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.

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.

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.

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.

Little Tern Chick Rearing (At the Kemigawa Beach Little Tern Breeding Area)

In late June, I visited the Little tern breeding area at Kemigawa Beach. It was a Sunday and everyone seemed to be staying indoors during the COVID-19, but there were some “beach goers” out enjoying themselves. There are also some “bird watchers” with their big, long camera lenses and looking through binoculars in one particular area of the beach.
The little tern breeding ground is a section of the beach roped off to keep people out of the area.

Both the eggs and chicks are very camouflaged, and I had a hard time finding them at first. I finally found them when the parent bird brought some food to the chick. After some time, once my eyes got the right search image, then I could confirm that there were eggs and chicks everywhere.

Two eggs and one chick.

One egg and two chicks.

These two chicks were a little bigger.

Probably the parent birds are stressed about getting enough food to their babies, but we on-lookers are filled with joy at seeing this precious sight. We can hear loving comments and coos coming from the bird watchers as they get their food.

It is so surprising to think that this is a sight so close to Tokyo City, just on the Tokyo Bay. It really impressed me that these little guys can breed and survive these tough situations in a small area surrounded by such a metropolis. I was so moved by what I saw this day.

(Video) An Asian Sheepshead Wrasse Named “Yoriko” in Hasama’s Underwater Park (Tateyama, Chiba)

The Hasama Underwater Park is located just on the border between Tokyo Bay and the Pacific Ocean, and it is within 2 hours travel time from the city center. The Underwater Park is rich with fish because of the input of nutrition from the freshwater rivers and the Kuroshio Current running along the coast of Japan. This place is quite famous for the underwater shrine Torii and ‘Yoriko’ the Asian sheepshead wrasse.

YORIKO Asian sheepshead wrasse　コブダイの頼子・波左間海中公園

The Asian sheepshead wrasse is called “Kobudai” in Japanese (as if it was a member of the Sea Bream family), it is a member of the wrasse family, and is a “hermaphroditic” species which can change sex between male and female. It first matures as a female and breeds, then changes sex to a male and participates in breeding again.

This “Yoriko” used to be a female paired with a male named “Yoritomo,” but one day “Yoritomo” disappeared perhaps because he lost the battle for territory. Following that development, “Yoriko” then became a male and has stayed that way to the present day. The lifespan of the Kobudai is thought to be about 20 years long, but “Yoriko” has already exceeded 30 years of age. He has come to be a very cherished and well-loved fish at the Hasama Underwater Park and taken on a mystic-natured creature who time has forgotten.

This is the famous underwater shrine, the only kind in the world, in the Hasama Underwater Park. It is an authentic shrine that was built in 1997 as a branch of the Susaki Shrine in Tateyama.

Another famous place in the Hasama Underwater Park is the “Sea Pen Colony” (in Japanese it is called ‘Yanagi-umiera’). It was the first time I could see these! Depending on the tide, it may or may not appear on the surface of the sand, so I felt so lucky to see the colony. The English name “Sea pen” is because of the resemblance to a Quill pen!

There are many other areas for great fish sightings as well. There is a fish-reef called “Dream” where the scenery created by the soft corals and Sea goldie, as well as Redbar anthias and Cooper’s Fairy Basslets. 。

This is the Spottedtail morwong cleaning station. The name for the fish in Japanese is “Takanoha dai” derived from the Japanese word for “Hawk feather” which is “Taka no ha.” This is based on the similarity of the stripes that are seen on hawk feathers, The polka dots on the tail also really catch my attention.

Here is a friendly pair of redlip morwongs.
