Skylark

The purpose of long song is still unknown

Come Spring, a long and familiar song is heard across the Japanese archipelago…
Eurasian Skylarks can be seen hovering high in the sky over their nesting grounds in the fields and meadows below. The purpose of this distinctively long song is still unknown, with some ornithologists claiming it to be a mating call, and others insisting it is territorial in nature. [5’17″/Subtitles: English]
