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. Common Pochard (Aythya ferina) is always observed in pure groups floating in the centre of relatively big ponds. 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. Maximum wetland birds observed in Kaithal District belong to Order Charadriiformes and to family Anatidae of Order Anseriformes. Spotted Greenshank (Tringa guttifer) is the peculiar to Pundri block only, in Kaithal District.

The pandemic influenza virus strains of 1918 (H1N1), 1957 (H2N2), 1968 (H3N2), and 2009 (H1N1) have genes related to avian influenza viruses (AIVs). The nonstructural (NS) gene of AIVs plays a significant role in host-viral interaction. However, little is known about the degree of diversity of this gene in Northern pintail (Anas acuta) ducks wintering in Japan. This study describes characteristics of pintail-originated H1N1, H1N2, H1N3, H5N2, H5N3, H5N9, and H7N7 viruses. Most of the viruses were revealed to be avian strains and not related to pandemic and seasonal flu strains. Nevertheless, the NP genes of 62.5% (5/8) viruses were found closely related to a A/swine/Korea/C12/08, indicating exchange of genetic material and ongoing mammalian-linked evolution of AIVs. Besides, all the viruses, except Aomori/422/07 H1N1, contain PSIQSR*GLF motif usually found in avian, porcine, and human H1 strains. The Aomori/422/07 H1N1 has a PSVQSR*GLF motif identical to a North American strain. This findings linked to an important intercontinental, Asian-American biogeographical interface. Phylogenetically all the viruses were clustered in Eurasian lineage. Cocirculation of allele A and B (NS gene) viruses was evident in the study implying the existence of a wide reservoir of influenza A viruses in pintail wintering in Japan.
