Cyrill of Alexandria
He seeks to illustrate to us in a different manner the reality encountered in the wilderness. While cities remain populated, the wild trees cannot thrive there, and the creatures that favor desolate areas remain afar. However, when these cities become abandoned and stripped of their inhabitants, they transform into barren land overrun with thorns, a refuge for ostriches and particularly for owls. The sirins, as he refers to the owls, are creatures that produce mournful sounds at night, akin to weeping, while they remain dormant during the day, nesting in forsaken spaces; they are more active in darkness, similar to other nocturnal birds.

Mt 12:43). The beasts that tend to evade human presence, driven to their wild state by inherent instincts, predominantly find their rest in such desolate areas.
