Which recent event do the crows mimic?
Or were they curlews?
Anyways, when they scream do they pretend to be 1950s businessmen?
Are they hiding in make believe bomb shelters, waiting for the Soviets to make their move?

Or are their shouts the sound of rioters, with bellows of “drain the swamp”
Jacksonian in nature. 
Waiting to attack like wild geese.
Perhaps they were geese?

Did their honks remind you of car horns
when the bridge collapsed
drowning four undocumented construction workers in a watery grave,
three were never found.

Are the birds refugees? 
Do they come from so much tragedy only to be faced with more?
Do they fly away in disgrace,
eyes turned mournfully at the sky?
