How does the architectural scale of Sociable Weavers' nests contrast with the Baya Weaver's dwellings?

Sociable Weavers construct massive communal nests, unlike the Baya Weaver's solitary, pendant-shaped homes

Weaver birds exhibit variations in social structure that directly influence their physical output on a large scale. The Baya Weaver is noted for building discrete, single-family dwellings that are pendant-shaped, although dozens may cluster together in one tree. In stark contrast, Sociable Weavers engage in cooperative architecture, maintaining a single, massive edifice intended to house hundreds of birds. This communal structure is often durable enough to last across multiple generations, representing a significantly different scale of physical endeavor compared to the solitary efforts of the Baya Weaver.
