The peregrine pulls out of his stoop. 它停止了俯冲
The falcons need to flush their prey into the open. 游隼需要将猎物驱赶到开阔地带
Diving from height, the falcons can reach speeds 游隼俯冲时的飞行时速
But their prey stay down low and close to the buildings. 但猎物躲在低处 离建筑物很近
And the great areas of concrete roasting in the sun create thermals, 烈日下大面积的混凝土散发的热量形成上升热气流
so that, with very little effort, the birds can soar over the city. 游隼不费吹灰之力便可以在城市上空翱翔
New York City has the highest density 纽约市的游隼密度
of nesting peregrines anywhere on the planet. 居世界之最
