“…We also recorded 32 sighting records of the N. percnopterus over three years. Prakash et al (2007; reported that N. percnopterus was recorded at the lowest levels in all road transect surveys, and this is a general trend throughout the NBR and the state of Tamil Nadu (Byju, Raveendran 2022).…”

Two resident and two local migratory vulture species are reported in the Mudumalai Tiger Reserve of the Nilgiri Biosphere Reserve. The early population estimates from the region are either scanty or crude. Vulture population estimation was performed using three different methods based on their breeding seasons and regional movements between 2019 and 2021. Road transect counts, nest counts, and carcass monitoring counts were used for population assessments. The road transect survey and nest site counting during the breeding season were conducted in all three years, while carcass monitoring was done in 2019 – 2020. For population estimation, three nest site colony counts were conducted for the resident Gyps bengalensis and for Gyps indicus. The other two methods, carcass monitoring and the road transect survey, were used for all four focal vulture species of the Mudumalai Tiger Reserve – Gyps bengalensis, Gyps indicus, Neophron percnopterus and Sarcogyps calvus. Significant variation in vulture population count was observed with different assessment methods.

“…Bird survey data provide useful insights for basic and applied ecology, as well as for identifying priority conservation areas (Daniels et al 1991;Peterson et al 2000). Some of the recently published records from this district include sighting of Artic Skua Stercorarius parasiticus (Byju & Raveendran 2022a), and the first Asian record of Light-mantled Albatross Phoebetria palpebrata (Byju & Raveendran 2022b). Previous findings highlight the importance of this area, and prompted us to undertake a baseline survey based on a need for monitoring in new areas in the rapidly changing landscape.…”

Avifaunal inventories are crucial to the formulation of conservation and management strategies for habitats and species. An annotated checklist of the birds of the Karangadu eco-tourism area located in the Palk Bay in Ramanathapuram district of Tamil Nadu, was prepared. We listed a total of 107 species belonging to 18 orders and 40 families. Orders Charadriiformes, Suliformes, and Pelecaniformes dominated the habitat. Among the families, Scolopacidae (10 species) was dominant, followed by Ardeidae (9), and Laridae (8). In addition, the study also documented three globally ‘Near Threatened’ species: Painted Stork Mycteria leucocephala, Black-tailed Godwit Limosa limosa, and Black-headed Ibis Threskiornis melanocephalus. The observed frequency of the species was: 57% (61 spp.) common, 32.7% (35 spp.) uncommon, and 10.3% (11 spp.) rare. Categorization based on the residential status of birds revealed that 31% (33 spp.) were winter visitors, and one was a passage migrant (Rosy Starling Pastor roseus). These baseline data highlight the importance of Karangadu as an important site on the southeastern coast of India for migratory shorebird conservation priorities.

Any new economic activity in a virgin area brings landscape changes, making it essential to document baseline biodiversity areas to understand the impacts on habitats. Avifaunal inventories are critical for previously undocumented areas, especially in a wintering site for shorebirds in the Central Asian Flyway, to formulate site- and species-specific conservation management tools. We present an annotated checklist of avifauna from the Valinokkam Lagoon in the Ramanathapuram district of Tamil Nadu. We recorded the first baseline avifaunal data for 154 species belonging to 16 orders and 46 families from August 2016 to February 2023. Order-wise, Charadriiformes dominated the study site with 47 species; followed by Passeriformes with 39 species and Pelecaniformes with 20 species. Winter visitors constituted 37.6 % (58 species) and one Passage Migrant Rosy Starling Pastor roseus. The relative abundance indicated that 94 species were C (common), 41 species were UC (uncommon), and 19 species were Ra (rare). Eleven Near Threatened (NT) species: Oriental Darter Anhinga melanogaster, Painted Stork Mycteria leucocephala, Black-headed Ibis Threskiornis melanocephalus, Spot-billed Pelican Pelecanus philippensis, Black-tailed Godwit Limosa limosa, Bar-tailed Godwit Limosa lapponica, Great Stone-curlew Esacus recurvirostris, Eurasian Curlew Numenius arquata, Curlew Sandpiper Calidris ferruginea, Red-necked Stint Calidris ruficollis and Red Knot Calidris canutus, one Endangered (EN) species Great Knot Calidris tenuirostris, and one unassessed Hanuman Plover Charadrius seebohmi according to the IUCN Red List category. This baseline data highlights the importance of Valinokkam Lagoon as an important wintering site in the Central Asian Flyway on the southeast coast of India for migratory shorebirds and the need for more conservation priorities for regional endemic birds like Hanuman Plover.

First Asian record of Light-mantled Albatross Phoebetria palpebrata (Foster, 1785) from Rameswaram Island, Tamil Nadu, India

Abstract: This document is a first sighting record of the Light-mantled Albatross Pheobetria palpebrate from Rameswaram island in Southern India. This is an unusual record from the region as it has not previously been recorded from either South Asia or the Oriental region.
