The study was carried out to assess the shorebird abundance and its diversity during September 2021 to September 2023 using direct observation and block count method, on the southeast coastline of India, with a study site located at Muttukadu backwaters (12.8006^oN latitude and 80.2363^o E longitude), Chengalpet district of Tamil Nadu. Our study documented 28 shorebird species from Muttukadu backwaters with four families that belongs to the order Charadriiformes. The mean abundance of shorebirds was higher in the post monsoon and followed by monsoon period due to the increased abundance of migratory species. The highest diversity of shorebirds was observed in the monsoon season. The data from rarefaction curve showed that post monsoon and monsoon had higher species richness than pre monsoon and summer. This survey of wintering shorebirds in the study area can be used for proposing the habitat management strategies.

这项研究是为了评估 2021 年 9 月至 2023 年 9 月期间在印度东南海岸线使用直接观察和分块计数方法评估鸻鹬鸟类的丰度及其多样性，研究地点位于 Muttukadu 回水区（北纬 12.8006 度，北纬^{80.2363度）}。东经），泰米尔纳德邦 Chengalpet 区。我们的研究记录了来自 Muttukadu 回水区的 28 种滨鸟，属于鸻形目 (Charadriiformes) 的四个科。由于迁徙物种的丰度增加，季风后和季风期之后，鸻鹬鸟类的平均丰度较高。在季风季节观察到滨鸟的多样性最高。稀疏曲线数据表明，季风后和季风期物种丰富度高于季风前和夏季。对研究区越冬鸻鹬类鸟类的调查可用于提出栖息地管理策略。
