What is a hummingbird man?
THE VISITING HOUR WAS ALMOST OVER, SO
the hummingbird man encountered only the occasional
carriage as he pushed his cart along the narrow strip of road
between the mansions of Newport and the Atlantic Ocean.
My Last Duchess by Daisy Goodwin
"[...] The sole heiress to her father's bread-flour fortune, she has grown up in a Newport mansion modelled on the Palace of Versailles, and her coming-out ball boasts 800 guests, fountains of champagne, and the release of a cageful of gold-sprayed hummingbirds at midnight." Guardian - My Last Duchess
The hummingbird delivery man? ;)
From a book called 'My Last Duches'.
