In spite of the anthropogenic pressure, Durgapur supports a high avian diversity. So far, 257 avian species belonging to 59 families were recorded with a citzen science efort during a period of more than fve years (2013–present). Out of these, fve species discussed here, are either not recorded previously or have few records: Hume’s Lark and Graceful Prinia were recorded from riverine habitat; and Lesser Racket-tailed Drongo, White-rumped Shama, and Indian Blue-Robin were recorded from woodland habitat. More extensive exploraton of this region with involvement of citzen scientsts in this study will enrich our knowledge about bird diversity, their migraton and distributon patern in this region. Keywords: Anthropogenic actvity, birds, drongo, lark, prinia, robin, shama.

Study area Geographically, it lies in the transitonal zone between The present study was carried out in Durgapur two ecoregions, Chotanagpur Plateau and Gangetc subdivision (23.480N, 87.32°E) of Paschim Bardhaman Plains. Complementng its unique geographical locaton, District, West Bengal, India and adjoining Damodar Valley this region harbours exceptonal biodiversity, having (Fig. 1). Durgapur is the 77th most populated city in India species from both the ecoregions mentoned earlier. with 566,517 people (as per 2011 census of Government Menton may be made that the Common Babbler Argya of India) and covers an area of about 154km2.

Soil, in this region, by various researchers, however, most of their studies is red laterite type. About 100 years ago, the total area focused on Damodar Valley (Gauntlet 1971, 1985; was covered by dense Sal Shorea robusta forest, which Chakraborty 2011; Hossain & Aditya 2016). Thus, it was was cleared gradually from the late 1950s to establish felt necessary to undertake a holistc study to get an idea India’s second planned city (Chakrabart 1989). about the avifaunal diversity of the entre city and its outskirts. This was the primary motvaton behind the Data collecton present work where, for the frst tme, the whole area A citzen science program, ‘Biodiversity of Paschim of Durgapur was taken into consideraton for studying Bardhaman’ (formerly known as ‘Birding Durgapur’) avifaunal diversity. We started a citzen science program has been running since 2013 to create interest among namely ‘Birding Durgapur’ in 2013 to accomplish our job. the citzens of Durgapur and adjoining areas for nature With increasing citzen science involvement, we increased watching by Durgapur Wildlife Informaton and Nature our area of work to the whole Paschim Bardhaman Guide Society.

In recent days, the citzen science for photography and feld binoculars for birdwatching. program has become a potental tool for biodiversity Nature watchers regularly post their eforts (eBird monitoring (Cohn 2008; Silvertown 2009; Devictor et al. checklists, photographs and call recordings) with date 2010; Theobald et al. 2015). Several web-based popular and place in the Facebook group. All observatons are programs (such as eBird, CBMI, MigrantWatch etc.) rely verifed by the group experts.

The volunteer citzen by using suitable feld guides (Grimmet et al. 2011; Ali scientsts minimize the difcultes of researchers to 2012; Grewal et al. 2016) while suitable feld guides study a large region. Increase in a number of observers (Grimmet et al. 2011; Baidya et al. 2017), online range in an area, in turn, increases the frequency of sampling, maps and databases (eBird 2017) and publicatons resultng in beter coverage and public awareness.

It may occur due to three possible reasons. distributon and occurrence of various bird species. A First, increase in the number of birds beyond carrying checklist of birds of Durgapur subdivision is contnuously capacity, forcing excess individuals to go beyond the range maintained by group members. to fnd suitable resources for their survival. Second, an increase in the number of observers helps to fll the gap in knowledge about the bird distributon patern.
