The parrot, screeching, flew out into the darkness,
Circled three times above the upturned faces
With a great whir of brilliant outspread wings,
And then returned to stagger on her finger.
She bowed and smiled, eliciting applause. . .
The property man hated her dirty birds.
But it had taken years--yes, years--to train them,
To shoulder flags, strike bells by tweaking strings,
Or climb sedately little flights of stairs.
When they were stubborn, she tapped them with a wand,
And her eyes glittered a little under the eyebrows.
The red one flapped and flapped on a swinging wire;
The little white ones winked round yellow eyes.
