Where the name “Grey heron” comes from
The Japanese name aosagi comes from its bluish feathers.
井の頭自然文化園It is the biggest heron in Japan, and it catches fish, frogs, insects and other animals at the water's edge to eat.
When the breeding season begins in spring, the color of its bill, legs and eyes changes from yellow to pink.
It usually lives alone, but at nesting time it gathers with others and builds its nest up in a tree.
How the Grey heron lives
It wades in shallow water or moves on land to find food. It catches prey with its bill and generally swallows it whole. It often roosts on the ground by day and takes cover in trees near dusk.
