Abstract
The present study is
concentrated on density variations of avifauna of three wetlands viz.,
Bannigola, Ankasamudra and Magadi lake because these three wetlands are
attracting the migratory and resident birds every year in considerable number.
The density of birds is indicating the potentiality of the habitat. Among these
three wetlands, in Bannigola wetland 12 Families emerged as major groups with
large number of bird population, each family with more than 1000 in numbers, in
Ankasamudra wetland 11 Families were major groups and family Sturnidae occupied
first place with 48.58% (especially Rosy starling population was the highest)
whereas Magadi lake attracted 10 Families as major groups (dominated by Bar
headed geese). Overall species richness is depending upon the spatial scale and
the variety of resources available in the wetlands. In contrast to this these
three wetlands are having abundant space, food availability and also place for
roosting and breeding. Hence these wetlands in North Karnataka emerged as
assured habitats for the migratory visitors and resident birds.
