This is BirdNote.
During the day, an American Robin sings a lovely, familiar song of rich phrases. The phrases vary, and ring forth with a lilting quality.
But as the sun begins to set, robin song takes on a new and exquisitely different character. From sunset until dark, a robin adds ethereal whispered notes to its carol, creating a song of remarkable grace and complexity.
Let’s listen more closely to the fine detail of a robin’s evening song, by slowing down the same notes to ½ normal speed.
Here’s another passage of evening song at 1/2 speed.
In the high latitudes, where twilight lingers late into the evening, a robin may expand its daytime carols into a twilight symphony that continues for hours.
Support for BirdNote comes from Forterra – creating great communities and conserving great lands in Washington State.
