Kaithal District is comprised of 2317 Km² Sq. Km area having six blocks Viz.:Kaithal, Kalayat, Pundri, Rajound, Ghula and Siwan located at a distance of 150 Kms from New Delhi toward North West. Its geographical position lies between 29° 48' 0 N latitude and between 76° 22' 60 E longitude.The present studies were carried between 2005-2008 with the help of Zenith Camera and telelens. In all, 63 species of Wetland birds belonging to 10 Orders, 38 genera and 16 families were observed in various village ponds in Kaithal District. Out of 63 species of wetland birds, 31 are winter migratory, 9 local migratory, 3 summers migratory and 20 species are resident birds. Considering IUCN categories, Black Ibis (Pseudibis papillosa) which belongs to Biome Restricted Species (BRS) was observed in three blocks viz. Kaithal, Pundri and Rajound of Kaithal district. In addition, Spotted Greenshank (Tringa guttifer) which has been placed in endangered category of IUCN was observed as single individual. But Black Ibis (Pseudibis papillosa) was observed in a group of three to seven. Northern Shoveller (Anas clypeata), which is reportedly coming from Central Russia and Caspian Siberia has been observed in very large groups of 200-250 and virtually spotted in each and every pond in Northern Haryana. Similarly, Northern Pintail (Anas acuta), Common Teal (Anas crecca), Common Pochard (Aythya ferina), Spot-billed Duck (Anas poecilorhyncha), Lesser-whistling Teal (Dendrocygna javanica) were also seen in relatively large groups.

In contrast, Gadwall (Anas strepera), Northern Shoveller (Anas clypeata), Northern Pintail (Anas acuta) and Common Teal (Anas crecca), share close proximity with each other in water and are found in mixed groups. Northern Shoveller (Anas clypeata), Bar- headed Goose (Anser indicus) and Northern Pintail (Anas acuta) stay between Octobers to April. Mallard (Anas platyrhynchos) stays in winter for shortest period between December and January.
