From mid fall to early winter, Japanese Cormorants migrate to Amami. They are 
often seen gathering on the rocks in the shallows, on mud flats or in mangrove 
forests. Since they are a water bird, they have webbed feet and dive for fish. 
Their feathers are blackish and their size is much bigger than a crow. The tip 
of their beak is hooked.
       
        When you are fishing at a seaside, you may happen to 
notice a cormorant dive at a spot. Then, you will be surprized to find it emerge 
at a very distant place after a few minutes. It's amazing how far and fast they 
can dive. They are often seen spreading and drying their wet wings on rocks 
after diving.
       
        Cormorant fishermen tame and train Japanese Cormorants 
to catch ayu (sweetfish). Master cormorant fishermen in the Nagara 
River, Gifu Prefecture, are the most renowned.
