The Vaux’s swifts that had been up
& down the river feeding on flying insects,
Began to draw close & come together
With high, rapid twittering, high whistled chipping,
In ever tightening circles,
Swirling & swirling,
They all go up to spin together in a great pinwheel-like circle,
Coming more & more altogether directly above the chimney,
Then suddenly,   in one morphic resonant being they come down
& into a whirling black-funnel-down tornado-like cloud gyre,
Fifty feet in height, above the house & then into-the-chimney
In a second or two,
Full of this day’s hatch settling & chittering for
Brick gripped sleep.
