Fastest Sea Bird

Frigate
birds (军舰鸟) are not only the fastest, but also the most acrobatic ocean-going
(擅长远洋飞行的) birds. Able to fly as fast as 93 miles per hour, they
can steal food from other birds while in flight, and snatch flying fish right
out of the air (迅速地捉到跃出水面的鱼) .

Specialized (擅长) for flight, they are unable to land on the water and are
awkward  on land. They build crude nests under low bushes , and lay only
one egg at a time.

The male frigate bird has a bright red pouch on the underside of his neck,
which he can inflate to attract females. When inflated, the pouch can be seen
for great distance.
