The Nature Mates Nature Club has released a dataset entitled "Avian diversity study (water birds) of Kamarganti Bheries, Haroa, North 24 parganas, West Bengal, India during winter season" Bheries are the type of fisheries generally practiced in low land impounded with earthen embankments all round. The age-old bheri-culture has emerged in North 24 Parganas District in its south and eastern skirts centering the lower course of the Bidyadhari River. Salinity in bheri-water is sourced from brackish sea-water entered through rivers and canals.. The district has 22 community development (CD) blocks, though brackish water bheri fishery is usually found to exist in its 13 blocks in the south and eastern skirts. This dataset is concerned with one such area, Kamarganti,Haroa,North 24 Parganas. A list of all the birds identified during a biodiversity survey carried out in the year 2023 is included in the dataset. During the survey Red Necked Phalarope (Phalaropus lobatus) was recorded which is a very rare bird in West Bengal. Species or genus-level identifications have been made for every species. There are 42 bird species total, with records of them in 16 different families and 10 different orders. This study can give a future scope in understanding how bheries affect the biodiversity of an area.
