The Shima-enaga is a long-tailed chickadee subspecies (Aegithalos caudatus) that lives only on Hokkaido, Japan’s second-largest island. Japanese people have loved this tiny bird for a long time and call it the Shima-enaga, which means “long-tailed island tit.” The birds have fluffy, pure white feathers and long tails, making them look like little snowballs hopping among branches.
Our research shows that the most popular articles about the Shima-enaga rank high because they successfully use the bird’s nickname, the “Snow Fairy,” and provide clear, simple guides on where to see the bird and buy merchandise. To make our article rank even higher, we must add specific, detailed facts about the bird’s unique biology and its deep connection to Hokkaido’s culture.
1. What Makes the Shima-enaga Unique?
The Shima-enaga subspecies stands out because of its completely white face.
A Tiny Bird with a White Face
The Shima-enaga is small, measuring 10–14 centimeters from beak to tail tip. Its long tail makes up about half of its total length. The bird’s body is covered in thick, fluffy white feathers, making it look round and soft.
The Adult Difference: Long-tailed Tits that live in other parts of Japan keep black “eyebrows” their whole lives. Shima-enaga birds, however, lose these black markings when they grow up. The adults end up with a completely white face, which helps them blend in during the long, snowy Hokkaido winters.
Taxonomy: This bird belongs to the Long-tailed Tit family, and its scientific name is Aegithalos caudatus japonicus.
Life in the Cold: Behavior and Survival
These energetic birds live in Hokkaido year-round. Their behavior changes significantly depending on the season, helping them survive the cold.
Flocking for Warmth
Shima-enaga are highly social. Outside of the breeding season (which runs from about July to February), they travel in cohesive groups or family flocks that usually have six to seventeen individuals. They move quickly through the forests, foraging for food.
Thermal Huddling: The birds flock together mainly because they struggle in cold weather. To survive the freezing nights, the whole group huddles together tightly. This communal huddle helps them save body heat.
Diet and Communication: Shima-enaga are insectivores; they eat insects, spiders, and their eggs, adding vegetable matter when food is scarce. They communicate constantly while flying and foraging, using a gentle contact call described as “‘juri, juri'”.
Reproduction and Cooperative Breeding
Shima-enaga birds typically breed once per year. The female builds an elaborate, dome-shaped nest using moss, lichen, and spiderwebs, lining it with soft materials. She lays between 6 and 15 eggs. Both parents help incubate the eggs and feed the young chicks. If other adult birds fail to breed, they often stay and help feed the young of the successful pairs, making raising the chicks a community effort.
Deep Roots: Bird and Hokkaido’s Heritage
The history of the Shima-enaga connects strongly with the history of Hokkaido.
The Ainu Connection
The Ainu people are the indigenous inhabitants of Hokkaido. They have a rich spiritual tradition rooted in deep respect for nature. Ainu beliefs state that spirits, called kamuy, live in all natural objects, including animals, plants, water, and fire. The Ainu treat animals with profound respect, viewing them as kamuy that visit the human world in disguise to bring gifts.
This belief system shows a long-standing cultural tendency in Hokkaido to revere its endemic wildlife, which helps explain the modern intensity of the Shima-enaga’s popularity.
Conservation Status and Threats
Today, the International Union for Conservation of Nature (IUCN) classifies the Shima-enaga as a species of Least Concern. This means they do not currently face a global risk of extinction.
However, the bird still faces major threats in Hokkaido :
Habitat Loss: Development and deforestation continue to destroy the forests and woodlands where they live and reproduce.
Food Loss: Changes in climate cause insect populations to become less abundant, making it harder for the birds to find the food they need.

The Shima-enaga’s charming appearance has made it a national celebrity, driving both tourism and a major merchandise market.
Prime Locations for Viewing
The best time to see the Shima-enaga is in winter. The cold weather forces the birds to fluff up their feathers (making them extra round) and stay in large, compact flocks, which makes them easier to find.
Reliable sighting spots include:
Maruyama Park, Sapporo: This is one of the most accessible places to spot flocks of about ten birds. The best time to look is during the early morning hours.
Obihiro Shrine: While a cultural site, the surrounding wooded areas offer potential sightings. The shrine itself sells popular omikuji fortunes shaped like the Shima-enaga.
Bird Watching Cafes: Specialized businesses near places like Chitose cater to photographers, offering managed environments to view the bird.
Where to Buy Merchandise
The bird’s popularity has led to massive commercial success. Major national retailers sell Shima-enaga-themed goods :
Big Box Stores: Nitori (Deco Home), Can Do, Don Quijote, and Shimamura sell everything from home goods (slippers, bedding) to apparel (hoodies) and toys.
Local Specialties: Tourists often buy the cute Shima-enaga omikuji fortunes at Obihiro Shrine
What makes Hokkaido myths so special?
Long-tailed chickadees, also known as Shima enaga, are beloved by the Japanese and can be found flitting among the trees in Hokkaido, Japan’s second-largest island. These fluffy white birds are only found in this region and have tails that run half the length of their bodies, measuring between 13 and 15 centimeters.
In Hokkaido, the species has a unique feature that sets it apart from its counterparts in other regions. As adults, they lose their distinctive black “eyebrows”, leaving them with a completely white face that resembles a small snowman.
Climate Change Impact
Shima Enaga faces significant challenges due to climate change. Japan’s climate is changing rapidly, and this is having a significant impact on the Shima Enaga’s habitat and food sources.
One of the main challenges facing Shima Enaga is the loss of its habitat. The bird lives in forests and forests, but many of these areas are being destroyed by development and deforestation. As a result, Shima Enaga is losing the places it needs to live and reproduce.
Another challenge facing Shima Enaga is the loss of their food sources. The bird feeds on insects, spiders and other small invertebrates, which are becoming less abundant due to changes in climate. For example, warmer temperatures are causing some insect populations to decline, making it harder for Shima Enaga to find food.
