Description
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 80 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods
Bird observation was carried out as per the Asian waterfowl census monitoring protocol, (Wetland International 2004,2009,2015). Total Census: Total Census of water fowls is been carried out at Santragachi and Ballavpur wetlands from 2006 onwards and continued till 2022. In this process all the individuals are counted by a team during 2nd and 3rd week of January. The members count separate species and the tabulation done on the format provided by Wetland International for Asian Water fowl Census. Spot Count In Gajaldoba (Teesta Barrage), Purbasthali (Chupi Char), Tilpara Barrage, the census carried out on Spot count method. These wetlands are not approachable on foot from all the side and counting from boat is required hence the wetlands are being divided in grids and then random grid point is selected and individual count has been done and then total number has been estimated. Timing of the Total census method: 11 am to 12 Noon because of Minimum activity of birds and Maximum visibility Methods for monitoring land use Remote sensing technology, including satellite imagery and aerial photography, is used to classify land use and monitor changes over time. Methods such as Normalized Difference Vegetation Index (NDVI) and Land Use/Land Cover (LULC) classification help identify areas of habitat loss and degradation (Pettorelli et al., 2011). GIS is used to analyze spatial data and create detailed maps of land use patterns. This information is crucial for planning conservation strategies and assessing the impact of human activities on Waterfowl habitats (Longley et.al., 2015). Arc-GIS software and Landsat and sentinel map (Landsat 7 and Sentinel 10) data has been used for understanding the Land use and land cover in an area of 5 KM radius from the roosting site.

| Study Extent | West Bengal comprises 6 distinct habitat and landscape. They are (i)Hill Zone, (ii) Terai Zone, (iii) Old Alluvial Zone, and (iv) New Alluvial Zone (v) Red and Laterite Zone, and (vi) Coastal and Saline Zone. Out of these 6 zones, the hill zone does not have any important wetland with migratory water fowl and has not been represented in the present study. In West Bengal there are about 54 natural and 9 man made major wetlands and most of them are frequented by the winter migrants. Depending on the distribution and to have all the landscape covered along with the different altitudinal variation Five important unprotected wetlands have been selected within the overlap area of the flyways of migratory water fowls for the present research work. These are (i) Teesta Barrage in Terai zone, (ii) Purbasthali in New Alluvial Zone (iii) Ballavpur in Red and Laterite zone and (iv) Tilpara Barrage in Old Alluvial Plain, and (vi) Santragachi Jheel in the Coastal and Saline. |
