推特“一路顺风”(Tweeting 'bon voyage')

你有没有想过鸟类每年穿越地球的旅程？今天，为了纪念世界候鸟日，我们介绍靛蓝彩旗，一种羽毛像黄昏天空的小鸟。他们利用恒星导航，穿越数千英里。这些鸟类在北美洲的繁殖地与中美洲和南美洲北部的越冬地之间迁徙。

Have you ever thought about the annual journeys undertaken by birds across the planet? Today, to mark World Migratory Bird Day, we introduce the indigo bunting, a tiny bird with plumage like the twilight sky. They traverse thousands of miles using the stars to navigate. These birds migrate between their breeding grounds in North America and their wintering grounds in Central America and northern South America.
