Abstract
India’s diverse physiography and climatic gradients support exceptional
biological richness, particularly of birds, which serve as sensitive indicators
of habitat condition and environmental change. Despite this, systematic
avifaunal assessments in Bihar’s forested protected areas remain sparse. Rajgir
Wildlife Sanctuary (WLS), located at the interface of the Chotanagpur Plateau
and the Gangetic plains, encompasses a heterogeneous landscape of Sal-dominated
forests, bamboo patches, scrublands, and rocky hill systems, creating a range
of ecological niches for avian communities. The present study provides a
preliminary assessment of bird diversity in Rajgir WLS with the aim of
establishing baseline information for conservation planning and long-term
monitoring. Birds were surveyed from March to October 2022, employing transect count methods across key habitats. A total of 77 bird
species belonging to 60 genera, 41 families, and 12 orders were recorded. The
assemblage was dominated by Passerines, with insectivorous and omnivorous
guilds most prevalent. Community structure was characterised by a few abundant
resident species and a large proportion of low-abundance taxa, while migratory
species were represented sparsely. Although temporally limited, the study underscores
the ecological significance of Rajgir WLS and provides a foundational reference
for future avifaunal research and management interventions.
