What orientation risk causes a Baya Weaver nest to be significantly more likely to fail due to wind shear?

Entrances facing the wind in windward locations

The male weavers exhibit an evolved understanding of aerodynamics, instinctively optimizing the nest's orientation relative to local weather patterns to ensure structural stability and survival. Research specifically indicates that nests situated in windward locations—areas directly exposed to incoming wind—are significantly more likely to fail if the entrance tunnel faces directly into this prevailing wind. This orientation exacerbates wind shear forces against the structure. Consequently, the weavers instinctively orient their tunnels away from the prevailing winds, effectively minimizing direct aerodynamic impact and providing better protection for the internal chamber.
