Correlation of urban avian species diversity present in heterogeneous habitat types of Berhampur city, Odisha, Eastern India

Abstract

This study was conducted for the first time in order to know the urban avian species diversity and their correlation among four habitat types viz. agricultural lands, human settlements, forest patches and wetlands present in Berhampur city, Odisha, Eastern India. Altogether 16 sampling points (4 points in each habitat type) were studied from November 2019 to October 2021. A total of 88 bird species were identified in 18 orders, 43 families and 72 genera. ANOVA revealed the abundance of birds among habitats varied significantly [F (3, 348) = 3.91, p˂ 0.05]. Agricultural land was the most speciose habitat (66 species, 1079 individuals). Insectivore birds dominated (34%) followed by carnivore (16%). Avian species diversity of agricultural land with human settlements, forest patches (r = 0.46, r = 0.53, p˂ 0.05) and human settlement with forest patches (r = 0.52, p˂ 0.05) is highly correlated.
