This Carolina Wren doesn't know the precise instant of the vernal equinox of course. But the wren senses the growing hours of daylight through a surge of hormones, which tell it it's time to sing. Both science and folklore tie Spring to the renewal of nature, as the world awakens from the long, cold winter. Spring has sprung - the birds declare it official.

Vernal Equinox - East

Ahhh, [Carolina Wren habitat] the first day of spring…at last! Let’s step outside and greet the new season. Clearly, the birds know somethin’ is up. Listen to that Carolina Wren belt it out [Carolina Wren song].
The wren doesn’t know the precise instant of the vernal equinox of course. It’s the moment when the sun is directly above the equator, and day and night are nearly equal all over the world. But the wren senses the growing hours of daylight through a surge of hormones, which tell it it’s time to sing [Carolina Wren song].
Both science and folklore tie Spring to the renewal of nature, as the world awakens from the long, cold winter. A Northern Cardinal pours out its liquid notes [Northern Cardinal song]. And, wow! There’s a tiny Ruby-crowned Kinglet, flashing its red crown. Listen to its bubbly song [Ruby-crowned Kinglet song]. [Oinking of Virginia Rail] Now there’s a comical sound, coming from the marsh. It’s a Virginia Rail, unseen but hardly unheard, ringing in the new season. [Oinking phrase of Virginia Rail vocalization].
Spring has sprung. The birds declare it official.
[Ruby-crowned Kinglet song]
