“…Bird species diversity in a habitat can illustrate how birds respond to habitat disturbance or change (Xu et al 2018). However, apart from species diversity, parameters to observe bird response can also be discerned through functional diversity (Fontúrbel et al 2022), a facet of biodiversity that assesses the diversity and distribution of functional traits among community members (Meynard et al 2011). Habitat change or disturbance may result in the replacement or erosion of functional traits already present in the community, thereby inducing alterations in the community's functions (Almeida-Gomes et al 2019;Mariano-Neto and Santos 2023).…”

Abstract. Nugroho SPA, Mardiastuti A, Mulyani YA, Rahman DA. 2023. Bird communities in the tropical peri-urban landscape of Bogor, Indonesia. Biodiversitas 24: 6988-7000. Amidst the urbanization threat, peri-urban landscapes can play an important role in biodiversity conservation, particularly among birds. Therefore, to study species and functional diversity of bird communities in the tropical peri-urban landscape, we observed four habitat types (forest, plantation, built-up area, and farmland) in the Ciampea-Dramaga Landscape, Bogor, Indonesia, from September to December 2020 and September to December 2021. A standard point method was used to observe birds, and several diversity indices were used for data analysis. Altogether, we recorded 11,290 individual birds of 61 species and 33 families. The species diversity tended to be higher in the increasing habitat succession stages. Forest had the highest species diversity (H?=3.17), followed by plantation (H?=2.87), built-up area (H?=2.54), and farmland (H?=2.23). Meanwhile, functional diversity revealed that all feeding guilds can be observed in the forest. The species richness of frugivore-insectivores dominated all habitats, and their abundance are also dominated in forest and plantation habitats. In contrast, granivores dominated farmland, and fly-catching insectivores dominated built-up areas. Due to its relatively high bird diversity in the study area, it needed to be conserved, including habitat management at the landscape scale, strengthening policies and conservation actions, and raising public awareness.

Deforestation is linked to the increasing prevalence of small forest fragments worldwide and an associated loss in functional diversity. However, our long-term understanding on how biodiversity and functional roles respond in such isolated fragments is limited, especially in Southeast Asia. We compared the bird community in a small primary rainforest fragment in the Singapore Botanic Gardens, a UNESCO World Heritage Site, using historical records in 1898 and contemporary surveys conducted in 1998 and 2018–2021. Species composition was expectedly dissimilar between the 1898 and contemporary bird communities (50%), driven mostly by turnover (45.5%) rather than nestedness (4.5%). Despite the changes in community composition and species extirpations, both species richness and functional diversity were retained. Our results suggest that small forest fragments can form novel bird communities that are functionally similar to previous communities that inhabited the fragment, leading to the retention of functional diversity. Such functional redundancy may be encouraged through habitat restoration initiatives adjacent to fragmented forests.
