How do cormorants fish for man?
In China and Japan the ancient art of cormorant fishing dates back for hundreds and hundreds of years. The cormorants are trained to fish tied to a long lead and with a leather thong around their necks. This prevents the birds form swallowing their catches which they disgorge into the boat when the owner pulls them in.
At the end of the night’s fishing the owner unties the thong and gives the cormorants their share of the catch to eat. Modern methods have made cormorant fishing uneconomic in Asia abut it is still demonstrated as tourist attraction.
Why is the frigate bird the pirate of the seas?
The piratical behavior of buccaneers of old has been compared to the way a frigate bird obtains food at certain times of the year. By flying alongside another bird and pecking at it until it realizes it cannot escape, the frigate bird obtains a meal for nothing.
If the victim has just fed, its crop will be full of half-digested mush. In fear, or to lighten its load so that it can escape the frigate bird, the bird will disgorge the contents of its crop.
This frigate bird pounces on as it falls and scoops it into its beak before it hits the water. You will realize from this that the frigate birds are superb fliers.
