It bursts upon dawn-stage
from half-cup nest tangle 
of twigs grafted to brick
      old cold chimney

trailing soot rocketing past nets
of ivy     clutch of near-trees
suspended in half-light
      from the final star

swoop   sweep   dive
singular aerial bolero
wing-stroke    pause
     stamps blue

with its pulse  flawless
performance    this is
how day breaks into
applause   how to be
     a survivor
