Whirl Décima

Dusk and the light begins to wane.
By the lake where the reeds grow high. 
Hear the chatter, the first go by.
My sheer delight I need not feign. 
This reed bed is where Starlings reign. 
Before they roost there's lifts and swirls.
Constantly the rabble unfurls.
Acrobatic undulations!
Chaotic yet in formation
A living mass that twists and whirls. 

A murmuration!
