Tweeting Trends: Unmasking the Birds of Madurai South, Tamil Nadu, India

Wetlands, acting as complex ecosystems bridging aquatic and terrestrial habitats, play a vital role in avian conservation. Despite the extensive use of bird communities in biodiversity conservation, there is a notable lacunae in baseline data, particularly for common avian species. This study aims to address this knowledge gap, providing a foundational dataset for avifauna in the wetlands of Madurai, Tamil Nadu. The survey conducted from January 2022 to December 2023 covered five wetlands: Madakulam, Thenkarai, Koothiyarkundu, Avaniyapuram, and Samanatham. A total of 151 species belonging to 55 families have been observed during the study period. The results highlight the prevalence of Passeriformes, with 51 species. Among the study sites, Samanatham recorded the highest species count, with 124 species, while Thenkarai site recorded the lowest with 82 species. Analysis of feeding guild revealed a diverse range of feeding habits, with 36% being insectivores. The analysis of relative abundance showed that 55% of the population is common (C), and concurrent analysis revealed 64% as residents and 27% being winter visitors. Notably, eight “Nearly threatened” such as Pallid Harrier Circus macrourus, Osprey Pandion haliaetus, Bar Tailed Godwit Limosa lapponica, Black Tailed Godwit Limosa limosa, Oriental Darter Anhinga melanogaster, Painted Stork Mycteria leucocephala, Spot Billed Pelican Pelecanus philippensis, Black Headed Ibis Threskiornis melanocephalus and three “Vulnerable” species, such as the River Tern Sterna aurantia, Greater Spotted Eagle Clanga clanga and Indian Spotted Eagle Clanga hastata, were observed. Throughout the study period, the months of March and April recorded the highest number of individuals across all study sites. A noticeable correlation between the abundance of microhabitats within the wetlands and the concentration of individuals was observed in the Madakulam site. In conclusion, this study serves as a critical step in addressing the dearth of baseline data for avian diversity in Madurai's wetlands. The findings contribute to the broader understanding of ecological dynamics and provide essential information for effective conservation strategies. To ensure a comprehensive approach in safeguarding the delicate balance within wetland ecosystems, ongoing monitoring will extend to environmental conditions, vegetation dynamics, other biotic resources, and potential threats to the avifauna.

Importance of conserving a critical wintering ground for shorebirds in the Valinokkam Lagoon—a first study of the avifaunal distribution of the southeastern coast of India

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.

Population abundance and threats to Black-headed Ibis Threskiornis melanocephalus and Red-naped Ibis Pseudibis papillosa at study sites in Jhajjar district, Haryana, India

The Black-headed Ibis and Red-naped Ibis are large wading birds of the order Pelecaniformes. This study documents abundance and threats affecting both species at Dighal, Gochhi, and Chhochhi villages located in Jhajjar district, Haryana, India. Field visits were made twice a month at each site from October 2020 to September 2021. Dighal had proportionately the largest populations of both species. Black-headed Ibis were most abundant in wetlands and Red-naped Ibis in agricultural areas. Populations of both species did not vary among seasons. Major threats observed included dumping of solid waste, fishing, growth of weeds, release of untreated sewage, collisions with transmission lines, grazers (e.g., cattle and goats), and stray dogs. The findings of this study suggest that despite having sizable populations near Dighal, both species face major threats and conservation efforts will require monitoring and management of ibis habitat.

Population status, habitat preference, and nesting characteristics of black-headed ibis Threskiornis melanocephalus Latham, 1790 in southern Rajasthan, India

The black-headed ibis Threskiornis melanocephalus is a medium sized (65–75 cm long) wading, nomadic Ciconiiform waterbird, gregariously frequenting shallow habitats. It is wide-ranging species distributed across the Asian continent and categorized as “Near Threatened” by IUCN (International Union for Conservation of Nature) because of decreasing population status from the last few decades. The present work describes the current population status, habitat preference in response to seasonal variation, and nesting characteristics of black-headed ibis T. melanocephalus in southern Rajasthan, India. Different surveys were performed in the study area at different temporal and spatial scales to assess different aspects. A total of 580 individuals (496 adults and 84 juveniles) were recorded during 2016, while 643 individuals (547 adults and 96 juvenile) in 2017. Juveniles represented 14.7% of the total population. The overall adult–juvenile ratio was 0.16 in 2016 and 0.17 in 2017. The encountered birds were found not significantly different seasonally in distinct microhabitats in both years (p<0.05); highest number was recorded in seasonal wetlands. Nesting sites were recorded in two districts (i.e. Udaipur and Dungarpur) along with eight other waterbird species. Cattle egrets Bubulcus ibis was the most commonly associated nesting species, while babul Acacia nilotica and vilayati babul Prosopis juliflora were the most preferred nesting tree species.
