M. THILAGAVATHI, S. MABEL PARIMALA
Abstract:
Birds are considered to be indicators of wetland ecosystem, management, restoration, and creation. The physio-chemical parameters of water quality such as pH, temperature, oxygen, chlorine, and salinity are important factors in creating reliable habitats. A study on wetland birds in the Vagaikulam river revealed 1.732 birds under 102 species from 33 diverse families. Their occurrence percentage showed a higher 7.75% in the Accipitridae family and the lowest 0.08% in the Anhingidae family. Maximum the species in Ardeolagrayii was abundant comprising, about 360 individual birds followed by Corvus splendens (301), Ciconia nigra (200), Acridotheres tristis (185), and Casmerodius albus (173). The number of birds observed, occurrence, species richness, and physiochemical parameters are good in the Vagaikulam river basin. The rich diversity of birds documented in the study site should be protected for conservation.
