Abstract.
Twenty-seven wetlands around Keoladeo National Park (KNP) were surveyed from 2009 to 2011. These wetlands were either on agricultural land or the dams that have been created mainly for supplying water for irrigation of the agricultural fields of surrounding areas. They ranged in distance from KNP from 4.3 to 125.82 km and area from 10 to 26,667 ha. The majority of the wetlands were from 10 to 400 ha in area. The relations of population abundance and species richness with other factors, i.e. water availability, distance and wetland size, were studied. Water availability was a very important aspect and played a crucial role for water birds. The highest bird diversity, H′ = 2.82, D = 0.084, as determined by the Shannnon-Wiener and Simpson’s diversity indices, was observed at Urmila Sagar located 61.82 km from KNP, but no correlation was found between distance and species richness. Moreover, no correlation was found between distance and population abundance also.
Key words: fauna, water birds, species richness, abundance, population.

Авифаунистическое разнообразие водно-болотных угодий вокруг национального парка Кеоладео, Бхаратпур, Индия. - Б.С. Бхадурия, В.Б. Матхур, К. Сивакумар. - Беркут. 23 (1). 2014. - В окрестностях национального парка Кеоладео (штат Раджастхан на севере Индии) расположены 27 водно-болотных угодий (ВБУ). В основном это запруды, созданные для ирригации. Они расположены на расстоянии от 4,3 до 125,8 км от парка. Площадь колеблется от 10 га до 26,7 тыс. га. В большинстве случаев ВБУ небольшие – от 10 до 400 га. В 2009–2011 гг. были проведены учеты птиц. По полученным данным определялось видовое богатство ВБУ и общая численность птиц. Анализировалась связь между этими характеристиками и другими факторами – обводненность, расстояние до национального парка, площадь ВБУ и т.п. Наиболее важным фактором было наличие воды, корреляция между количеством видов, численностью птиц и расстоянием до парка не отмечена.
Ключевые слова: фауна, водные птицы, видовое богатство, обилие, численность.
