Flying formation

Hundreds of thousands of spectacled teals fly in formation on Dec. 2, creating strange images in the sky as they fly over a lake on Gochang County, South Korea. The spectacled teal is a migratory species that breeds in central and eastern Siberia and spends its winters in China, Japan and Korea.
