*3.3. Relationship Habitat Diversity and Number of Birds*

At the five traditional folk villages, habitat diversity highly influenced nesting type diversity (R<sup>2</sup> = 0.74, Figure 5a), and has a weak relationship with diet type diversity (R<sup>2</sup> = 0.35, Figure 5b) and overall number of birds' species (R<sup>2</sup> = 0.31, Figure 5c). These results indicate that habitat heterogeneity of traditional rural landscape can provide diverse nesting resources for birds and indirectly affect the functional groups such as insectivores, granivores and predators.
