Sommaire partiel
The irregular rainfall in semi-arid zone of Gujarat has often resulted into scarcity ofwater. This had given rise to the concept of “one village one pond” to fulfill the needs for water. To overcome the scarcity of water faced by the farmers for irrigation, in Vadodara (22°17”N, 73°15”E), numerous water/ irrigation reservoirs were constructed during the Majestic rule of His Highness Shrimant Maharaja Sir Sayajirao Gaekwad III of erstwhile State of Baroda. Out of these, two irrigation reservoirs Wadhwana Irrigation Reservoir (WIR) and Timbi Irrigation Reservoir (TIR) and two village ponds : one rural Masar Village Pond (MVP) and one urban Hami Village Pond (HVP) in the outskirts ofVadodara city are selected in the present study. These waterbodies, with their shallow waters are considered as Wetlands that support the diverse flora and fauna. These habitats, being the transitional zone between land and water are highly productive and show dynamic characters. Among the diverse flora and fauna supported by the wetlands birds, that are designated as health indicators, form a prominent component used for the assessment of a habitat. It is known that the main factors affecting bird congregations are the habitat characteristics and the availability of prey. Hence, birds are studied in detail with some ofthe important biotic and abiotic parameters known to influence the productivity of wetland thus in turn the congregation of birds. An attempt is also made to correlate these parameters with bird congregations.
