摘要：Valley of Kashmir is well known for its vast avian diversity and its full bloomed wetland ecosystemswhich encompass four Ramsar sites and many other wetlands and lakes. The study was carried out at Haigam wetland,Kashmir from February 2015- March 2016, with the objectives to determine avian diversity and abundance. Striptransectmethod and point count method was employed. The Haigam wetland provides habitat for a large number ofbirds belonging to 78 genera. Despite being distinguished for winter visiting waterfowl species, the wetland isdominated by passerine bird species with around 38 species known. About 103 species of birds have been recorded.The species composition was significantly different during different seasons. Diversity was calculated using bothShannon-Weiner index and Simpson’s index of diversity. The diversity trend follows spring with highest diversity (H=3.939), followed by summer (H=3.848), autumn (H=2.696) and lowest in winter (H=2.538). Spring season showedmore evenly distributed avifauna (E=0.524) and lowest evenness during winter season (E=0.328). Typha spp.harvesting, hunting and cattle grazing are major threats to the wetland birds.
