ABSTRACT
Sathurukondan situated within the urban area of Batticaloa and adjacent
to Batticaloa lagoon. This area lies in the migrant route disperse from the
entry points from Eastern and Andaman route. This area is locally notable for their bird diversity as well as being a
major habitat in Batticaloa. Blooming of urbanization causing drastic reduction of
the mangrove forest is the main threat to these birds diversity due to their
habitat loss. Considering that, the objective of this
study was to determine the
taxonomic composition and abundance of water and wading bird in this area. Point
transact method was used to count the birds, and the counting was taken
monthly. A total of 8,893 records of 65
species representing
36 families were recorded from July 2015 to
July 2016. Simpson’s diversity index and Shannon index in this area are about 0.95 and 3.34, respectively, showing the high diversity
of this area. Migrant birds, such as common
sandpiper (Actitis hypoleucos L.), marsh sandpiper (Tringa stagnatilis B.), common greenshank (Tringa nebularia G.) and other important species, such as lesser adjutant (Leptoptilos
javanicus H.), spot-bill
pelican (Pelecanus philippensis G.) and near threatened jungle owlet
(Glaucidium radiatum T.) were noted. This area contributes
notably to the local avian biodiversity and has the ecotourism potential. It conceals the need of the conservation of this area.
