A dead pigeon on the street is an object that pulls a person out of the flow of everyday affairs. Having lost the usual signs of a living being, the bird finally asserts its objectness.
The sequins create a contrast between the repulsive image of death and the attractive shimmer. This contrast emphasizes the state of a sudden collision with a dead pigeon in the city - a desire to pass by as soon as possible, but at the same time an irresistible urge to consider the deceased archetypal symbol of peace.
