Red-crowned Crane Tancho Grus japonensis Endangered (EN) Special Natural Treasure of Japan
Grus japonensis

L=140, W=240cm. Aynu, indigenous people who had lived by hunting and gathering in severe environment in Hokkaido, thought that spirits inhabited all creatures. The Red-crowned Crane, which lives in the boundless expanse of wetlands, was called 'Sarurunkamui' which means the 'God of Wetland' in their language, with feeling of awe and respect.

The Red-crowned Crane is one of the biggest birds in Japan at 140-150cm and with wingspan of 220-240 cm. The entire body is white, while from bill to neck and a part of wings are black, and the top of the head is red. From its characteristic head color originates the Japanese name of "Tancho"('tan'= red, 'cho'=top). It is a resident species in Japan. About 1,300 individuals live in the eastern part of Hokkaido, and Kushiro Shitsugen is their largest habitat. The bird raises chicks in vast wetlands and it is thought that one pair requires at least 100 ha (1㎢) as a territory.

The Red-crowned Crane is an omnivorous bird which eats small fish, frogs, crayfish, shell fish, insects and seeds of plants.

At Tsurui-Ito Tancho Sanctuary, you can easily watch cranes gracefully dancing on the snowfields in winter.

Haliaeetus pelagicus

L=95, W=220-245cm. With huge beak in bright yellow and a longer wedge-shaped tail. Overall blackish with distinctive white shoulder (actually, parts of lesser and median coverts are white). This species breeds only along the coast of the Okhotsk Sea. In Japan, it visits in winter, mainly in northern Japan, and is especially abundant in the eastern part of Hokkaido. It is often seen along coasts and occasionally in inland rivers and lakes. Basically, a fish eater, but sometimes eats ducks too.

Widely distributing in the Eurasian Continent. The species occurs in eastern Hokkaido throughout the year and breeds there. In winter, the numbers of the bird increase as those migrants from the continent join. The species can be seen along the coasts, lakes and rivers and is often seen together with the Steller's Sea Eagle. Feeding habit is the same as the Steller's Sea Eagle, which mainly eats fish.

During breeding season, a male bird flies around calling 'zubiyahk zubiyahk' and displays during its descending flight with roaring sound of 'gah gah gah ----' made by its outertail feathers. This species breeds only in Japan and Sakhalin, Russia and migrates to Australia to winter there. In eastern Hokkaido, the bird occurs in grasslands and meadows from lowland to mountain areas.

Birding sites around the sanctuary

Tsurumidai:

Tsurumidai

Another major feeding ground for Red-crowned Crane in Tsurui Village. Many people visit here in winter because of the easy access from the nearby prefectural road. An elementary school was originally located here and the school fed the cranes. After the closing of the school, Mr. & Mrs. Watanabe, residents of the village, started feeding the cranes. The feeding period is from November to March, twice a day at 9:00 am and 2:00 pm. About 300 Red-crowned Cranes appear at the peak period from the end of December to January.

Location:
Otowa-bashi Bridge:

Otowa-bashi Bridge

Otowa-bashi bridge is one of the bridges over the Setsuri-gawa river which runs in Tsurui Village. A roost of Red-crowned Crane is formed at the downstream in winter. This site is the only place where people can observe cranes at roost without threatening them. A parking area and sidewalks are well maintained here. In the early mornings in the coldest periods of January and February, flocks of the Crane can be observed roosting here in the river fog, in the mist or sometimes in the diamond dust. Many visitors gather around here to take photos. Occasionally, Steller's Sea Eagles and White-tailed Eagles appear in forests along the river, and up in the sky.

Location:
Onnenai:

Onnenai

Onnenai is located in the south-western Kushiro Shitsugen. It is one of the handful places where people can enjoy walking in Kushiro Shitsugen because boardwalks are well equipped. The wetland environments are varied with such as low moors, high moors and alder forests here. In summer, people can hear songs of grassland birds such as Siberian Rubythroat, Black-browed Reed-warbler and Middendorf's Grasshopper-warbler. Yellow-breasted Bunting, which has been sharply decreasing in number in recent years, comes to the high moors. At the entrance to boardwalks, there is a visitor center which provides information about the history and wildlife of Kushiro Shitsugen. In winter, people can walk on the wetland covered with snow all over wearing rental snowshoes.

On the opposite side across the prefectural road, there is Onnenai Wild Bird Protection Area designated by Wild Bird Society of Japan, where breeding of Red-crowned Crane has been confirmed. The site is closed to the public.

Location:
Shimokuchoro:

Shimokuchoro

Shimokuchoro is a dairy region closest to Kushiro Shitsugen in Tsurui Village bordering on the northern edge of the marsh. There are a lot of water channels in the huge meadow. People can watch non-breeding, immature Red-crowned Cranes from their cars, as well as small birds like Reed Bunting and Russet Sparrow in summer, and in autumn Bean Goose, which migrates through this region (be careful not to disturb the area's traffic and farming work).

Location:
Kottaro Shitsugen:

Kottaro Shitsugen

The northern end area of Kushiro Shitsugen is called Kottaro Shitsugen of which panoramic view can be seen from the observation deck on a small hill. A few pairs of Red-crowned Cranes breed in this marsh from spring to summer, which people can see from a long distance. The pebbled road runs from the first observation deck to Tohro-ko lake through the marsh, so that the visitors can easily watch Siberian Rubythroat in summer and Siskin, Redpoll and Pallas's Rosefinch in winter. Raptors such as Buzzard, Steller's Sea Eagle and White-tailed Eagle are often seen on the trees.

Location:
Tohro-ko lake, Shirarutoro-ko lake and Takkobu-ko lake:

Tohro-ko lake, Shirarutoro-ko lake and Takkobu-ko lake

As the reminder that Kushiro Shitsugen was once in the sea, there are a number of lakes in the low-altitude east part of the wetland. Three lakes, Tohro-ko lake, Shirarutoro-ko lake and Takkobu-ko lake, especially, have large water surface, and a good number of bird species use them in spring and autumn before and after the winter freeze. Whooper Swan, Bean Goose, Goosander, Goldeneye and Black-headed Gull visit the lakes in flocks. Many Steller's Sea Eagles and White-tailed Eagles gather here during the spring thaw. Red-crowned Crane is occasionally seen along the shores of the lakes in summer.
