Roosts of Eurasian Marsh Harriers Circus aeruginosus were studied for four winters between 1996 and 2000 in and around Keoladeo National Park (KNP), eastern Rajasthan, India. Fourteen communal roosts were found, in which harriers gathered in loose aggregations of 11-32 birds. Roosts were situated in tall grasses and wetlands with floating vegetation in KNP, and in tall grasses, sedges, crops and bare ground in areas adjoining KNP.

VERMA, A. (2003): Feeding association of Marsh Harrier (Circus aeruginosus) with Black-necked Stork (Ephippiorhynchus asiaticus) in Keoladeo National Park (Bharatpur, India). Aquila 109-110, p. 47-50. A total of 21 observations were made on Black-necked Stork capturing, killing and feeding on Coots (Fulica atra) on the wetlands of Keoladeo National Park during the winters of 1996 to 2000. It was always the male which killed and devoured the Coot first and later it was shared by both the female and juvenile Black-necked Storks. In the process generally the wings and legs of the prey were discarded which were often picked up by Marsh Harriers, especially females and juveniles.
