Tree Swallow
Tachycineta bicolor
 (L 5.75" WS 14.5" Wt 0.7 oz)
Can be found in huge flocks
outside of the breeding season.
Across the millstream below the bridge
Seven blue swallows divide the air
In shapes invisible and evanescent,
Kaleidoscopic beyond the mind’s
Or memory’s power to keep them there.
