Death of a Robin

Robins, in a carefully hidden nest, are not safe from the knowledge of serpents. Neither are they safe from falcons.
Whatever the case, we make the choice. Either the nest is made too low for serpents to reach, or the birds are high enough to be noticed by falcons.
Bonny, Yogesh, and Ray were the three robins in the City of Constantia. Bonny Deut died fourteen years later, in the back of the truck, trying to get back to the humble Province of Ignorance. His elder son, Yogesh, pined away in a mental institution in the City of Constantia. Ray got away.
Were Bonny and Yogesh responsible for their fates? How did Ray escape the falcons?
