| Popis: | Despite the declining global population trend of several riverine birds, inadequate attention has been given for their conservation. We monitored the nesting activities of Endangered Black-bellied Tern, Indian skimmer, Vulnerable River Tern, Near Threatened River Lapwing and Great Thick-knee for three consecutive years from 2017 to 2019 along the Mahanadi River in Odisha, eastern India. We calculated the nesting success rate as the proportion of success nests to the total number of monitored nests and identified the causes of nest failure examining the nest and its surroundings. Factors responsible for nest failure were flooding (46%), predation (28.6%), desertion (12.2%), trampling (7.1%) and egg collection (6.1%). Formulation of an evidence-based multi species conservation action plan to protect these threatened riverine birds is urgently required and its successful implementation needs support from the Irrigation and Revenue Department. Human induced disturbances can be minimized through community awareness. |
