“…Long-term research offers distinct perspectives on how gradual and nuanced processes of urbanization, lasting effects of land use, delayed reactions over time, and intricate occurrences impact avian populations in urban environments (Gopalan & Radhakrishna 2022). For example: through long-term monitoring in India, the Indian Council of Agricultural Research has pointed to a rapid decline of house Sparrows up to 88% in Andra Pradesh, up to 20% in Kerala and up to 70-80% in Gujrat and coastal areas (Maxmellion et al 2020).…”

Urbanization is increasing at an unprecedented rate, leading to changes in land use resulting in the loss of habitat for birds worldwide. Nevertheless, urban areas still support approximately 20% of the world's bird population. In Nepal, urbanization has been rapidly increasing in recent decades, yet little attention has been paid to urban biodiversity exacerbating the impact of urban expansion on threatened birds. In this perspective article, we explore studies on urban birds in Nepal to identify existing research patterns, discuss what has been known, outline gaps and pave immediate future interventions in studies of avian urban ecology in Nepal. There has been a significantly lower number of studies on urban birds in Nepal compared to neighbouring India and China in the last 10 years. Studies of urban birds in Nepal are at a very early stage focused on the diversity and richness in Kathmandu, Pokhara and Butwal with no baseline data for other major cities. Our understanding of bird homogenization or extinction as well as the effects of birds on cities, such as their rapid colonization and potential role as pests, may be limited by this dearth of knowledge about urban birds and biodiversity. Therefore, we have outlined future research opportunities in avian urban ecology in Nepal such as long-term bird surveys, interdisciplinary field of studies, diseases study, management of urban green spaces, avian adaptation to urban environments, colonization and extinction patterns in cities, and conflicts, challenges, and management strategies related to urban avian ecology. With this article, we call the immediate attention of scientists, urban planners, and related stakeholders to use birds as a model system to study urban environments which could be a good start in building a bird-friendly city.

“…More than half of the world’s population lives in urban areas – increasingly so in densely populated cities (Ritchie and Roser 2018); by 2050 it is projected to increase to 68% (UN DESA 2019). Deforestation, fragmentation and loss of connectivity caused by the rapidly increasing urbanisation have caused many wildlife species to live in close proximity to urban areas (Bonte et al 2004; Gopalan and Radhakrishna 2022). Urbanization-induced habitat destruction and fragmentation are often the leading causes of changes in community structure and subsequent deterioration of ecological interactions between species and trophic systems (Seto et al 2012; Lowe et al 2018; Seibold et al 2019).…”

The homogenous nature of the urban environment rapidly alters community dynamics of extant flora and fauna due to short-term spatial and temporal factors. However, such impacts of urbanization are mostly investigated in terms of taxonomic diversity, while its impact on functional diversity remains poorly understood. Whereas taxonomic information is limited to the identity of species, functional traits determine the relationship between species identity and ecosystem functioning. Studies investigating the role of urbanization in altering these ecological parameters have mostly focused on avian communities or plant species, while arthropods such as spiders which are integral components of urban households have largely been overlooked. This study aims to understand the impact of urbanization on both taxonomic diversity and functional diversity of spider assemblages across an urban-semi-urban-forest gradient in Guwahati, a rapidly growing city in northeast India. We surveyed spiders at 13 sites representing four habitat types (urban, urban parks, semi-urban, and forests) using belt transects, and also recorded functional traits relating to key life history processes. Spider species composition differed significantly between various habitats. The taxonomic diversity of spiders was highest in forests and lowest in urban parks. The turnover component was the major contributor to changing the beta diversity of spiders. Reduced diversity in urban regions was likely due to the dominance of a few synanthropic species. Generalised linear mixed-effects model analysis indicated that the habitat types significantly impacted spider abundance. Functional richness was maximum in forests (Fric = 23.43) and minimum in urban habitats (Fric = 12.98), while functional divergence was maximum in urban sites (Fdiv = 0.79). Our study demonstrates that urban land-use change can alter the structure and functioning of the spider community.
