Chinese fishermen are smart. Why go through the hassle of actually catching the fish yourself when you can have birds do it for you?! Each fisherman has a couple trusty Cormorants perched on their bamboo raft ready to dive into the river at the first sign of a fish. The cormorants have a snare tied to the base of their throats to prevent them from swallowing their hard-earned catch. When they come back to the raft, the fishermen just pull the fish out of their throats and dinner is served. It is a bit sad, but the birds do get fed in the end so I guess it all works out. Here is a picture of the bird after having caught a fish and futilely attempting to swallow it for the 100th time. They're great at catching fish, but they get tricked every time.
