What distinguishing feature differentiates the nest of the Sociable Weaver from the Baya Weaver's structure?

Answer

The Sociable Weaver builds a massive, shared thatched roof structure, while the Baya Weaver builds discrete, individual spheres.

Although both the Sociable Weaver and the Baya Weaver are masters of their craft, their architectural approaches reflect fundamentally different social structures. The Baya Weaver (*Ploceus philippinus*) focuses its effort on creating discrete, individual nests, often starting as an upside-down retort that culminates in a functional sphere with a vertical tube, suitable for a single breeding pair. In contrast, the Sociable Weaver (*Philetairus socius*) engages in a communal strategy, constructing immense, shared thatched roofs that house numerous breeding pairs, sharing the load and providing collective resilience that far exceeds the scope of an individual effort.
