Fishing is for the birds—literally. Fishermen of the Li river, one of the cleanest in China, use actual birds (the Cormorants) to swoop down and catch their dinner for them.
It's a thankless job for the birds, and the fishermen get some pretty decent meals, but how do a fishermen and a bird end up working together?
One would probably think that it's a great deal for the birds. They are brought to a plentiful lake and set loose to prey on all the fish they can eat.
But it's not quite like that. The fishermen put a stop to that by tying a little noose around the bird's necks to keep them from swallowing their prize.
The fishermen then bounce on their rafts to give the signal and encourage the birds to move through the water like fish-seeking missiles. A single morning can yield a decent bounty, a couple of dozen decent sized fish!
The birds are trained to return to the raft after a catch and are rewarded for their work. In fact, the Cormorants can actually keep a tally of up to seven fish they catch. If they aren't rewarded properly, they will refuse to work!
