ABSTRACT

Birds are important ecological indicators of an area and provide significant ecosystem service. Natural habitats of birds are destroyed by urbanization, resulting in reduction and alteration of avifaunal diversity. Green coverages of the city have an important impact on urban avifauna diversity, facilitating urban climate, nesting, breeding and migration of birds. Chintamoni Kar Bird Sanctuary (CKBS) spreads over 17.19 acres of land, located at Narendrapur, near Kolkata, West Bengal, India. The plantation type, texture, and resources attract various avifauna, residents as well as migratory to this site. Thus CKBS acts as an attractive survey site for the study of avifauna diversity in urban microhabitat. The survey period of one year (April, 2019 to March, 2020) was categorized into winter, summer and rainy seasons. The inspection was conducted primarily by line transect method and bird census report was prepared for analysis of seasonal fluctuations. The study recorded a total of 618 birds that were categorized into 9 orders, 20 families and 31 species. Among these, birds of order Passeriformes were the most predominant. Birds with omnivorous food habit and resident status were also very common. Winter migrants were more prevalent than the summer one. The richness, abundance and diversity of birds were maximum in winter season compared to other seasons, while bird evenness was high in all seasons. This primary survey at CKBS is an attempt to make people aware of the local avifauna diversity and motivate urban planners to emphasize green cover to conserve the avifauna diversity in urban areas.
