Mild and Tune – Sparks in Winter

Written by Bryan Pfeiffer

That is BirdNote.

Even within the ruthless grip of winter, when the snow crunches beneath your boots, an ember glows within the lilt of a Black-capped Chickadee.

Even within the northern states, the place the Arctic can appear too shut for consolation, springtime erupts from the music of a Home Finch.

Even now, in February, when the air outdoors is brittle and painful, heat rides the rhythm of an American Robin.

No, spring isn’t simply across the nook — at the least not within the north. However even in winter, some birds greet the dawn with music.

[Chorus of the same three species]

We usually hear the daybreak refrain in springtime, when birds sing to outline territory and entice mates. However birds don’t breed by heat alone. Day size is a much more dependable spark than climate. And in February, as the times develop longer, birds start to sing a prelude to spring.

It’s not completely clear how they measure day size. However we do know that photo-receptors in birds’ brains sense the growing gentle. It triggers the manufacturing of hormones, which helps convey on the breeding season. 

[Chorus of the same three species]

For BirdNote, I’m Michael Stein.
