Japan’s Hokkaido Island is home to an unusual species of long-tailed tit birds that look exactly like cotton balls with black spots for eyes. These birds are found in other regions of Europe and Asia, but the Hokkaido species is especially distinct from the rest with their pure white faces and cotton-wool-like bodies.
Hokkaido is Japan’s most northernmost island and has been preserved for centuries as a hub of wildlife and tourism. The animals that live there are very comfortable with people, and it’s no wonder why these cotton balls birds are so social. The bird is called shima-enaga.
They are often 13–15cm long in adulthood and weigh between 7–9 grams. They are easily identified by an immaculately white face and neck with a stream-lined body ending in a long, dark-colored tail. 
The birds live such a communal life that their offspring can be catered to by other members of the flock. While some members are tending to the incredibly tiny babies, others are out there searching for worms or bits of food to bring home.
These birds are sweet, social and friendly, but if you want them flocking all over you like they’ve known you forever, go along with some birdy treats such as peanuts, breadcrumbs, tiny seeds and pizza crusts.
