Like clockwork each year, starting around mid-February and peaking around mid-March through early April, hundreds of thousands of sandhill cranes fly to the Big Bend in Nebraska's Platte River. The large grey-feathered birds, known as the bright red skin above their eyes, a loud call that can be heard up to a mile away, and a wingspan of up to 7ft, traveling around 350 miles a day from Texas, Oklahoma or Mexico to stop in Nebraska on their way to their breeding grounds, which are spread across the northern United States and Canada. The sight and sound of nearly the entire population of the world's oldest living bird species is awe-inspiring. For the best views of the cranes, you will need to be in place well before sunrise, dressed in warm clothes and ready to stand quietly for about two hours. Long before you can see the birds along the river, you can hear them. Calling to each other through the night, the birds do not ever seem to stay quiet. Amazingly, a mother can distinguish her baby's call from amid the noise. When the sun starts to rise, the noise will, incredibly, increase as all the birds begin to wake up. Without warning, or at least without one that you can determine, nearly an entire group, hundreds of birds, will take flight at once in a whoosh of wings and calls that will take your breath away. And when the early morning sunlight hits the underside of their wings, they take on a golden glow.

译文 / 解析

每年有数十万沙丘鹤途经内布拉斯加普拉特河，观鸟者可在日出前聆听并目睹它们成群起飞。

每年像时钟一样准时，大约从二月中旬开始，三月中旬到四月初达到高峰，数十万只沙丘鹤飞往内布拉斯加普拉特河的大弯。这些大型灰羽鸟以眼上方鲜红的皮肤、一英里外可闻的鸣叫以及可达7英尺的翼展为人所知，它们每天飞行约350英里，从得克萨斯、俄克拉荷马或墨西哥来到内布拉斯加停留，再前往遍布美国北部和加拿大的繁殖地。

几乎整个世界上最古老的现存鸟类物种齐聚一处，景象与声音都令人敬畏。要看到最好的鹤群，你需要在日出前很久到位，穿上暖和的衣服，安静地站大约两小时。

在河边看见它们之前很久，你就能听见它们。它们整夜彼此呼唤，似乎从不安静。令人惊讶的是，母亲能从嘈杂中分辨出幼鸟的叫声。太阳升起时，叫声会不可思议地增强，因为所有的鸟都开始醒来。

没有任何预兆，或者说没有你能确定的预兆，几乎整群、数百只鸟会同时起飞，翅膀与鸣叫的呼啸让你屏息。清晨的阳光打在翅下时，它们会泛出金色的光。
