Here's a nice visual reference for the lines: When the Bakhtiari herd their goats back/Into the highlands ... a 10-minute documentery film on the annual Bakhtiari migration in Iran. http://www.youtube.com/watch?v=IljkR_y9Or8&feature=player_embedded#at=157
In late October, a chill settles in the basement.
In the third floor bedroom, an antiqued-blue chest
At the foot of the bed becomes a nesting ground.
Several species of shorts winter here: cut-off denims,
Silk boxers, one-hundred-percent-cotton chinos.
Plaid baggies puff their pleats to scare interlopers.
Mating pairs entice each other with floppy pockets.
The shorts breed; they rear; they remain for months,
Fighting off wash-day trespassers, day-old underwear,
Wallets, wedgies, and wanderlust. In mid May,
When the Bakhtiari herd their goats back
Into the highlands; when the Pennacooks hike north
To Concord; when martins, swallows, terns, and warblers
Wing their way up coasts, the shorts tentatively explore
The second floor, testing the breezes, warming to travel.
