The Eastern Ghats of Tamil Nadu have been poorly surveyed for birds.  The best known bird survey in the Eastern Ghats of Tamil Nadu (EGTN) was by V.S. LaPersonne who carried out the the Surveys in Tamilnadu Eastern Ghats between 08th April, 1929 and 25th July 1929. This was reported by WHistler & Kinnear.  Thereafter information about birds in EGTN has come only from checklists published from time to time, by researchers, whose primary focus was not birds.  Hence, to fill this lacuna, a comprehensive survey of birds was undertaken in the EGTN from March 2012-–--February 2015.  The objectives of the study were to document the avian richness and abundance in EGTN, put them in perspective to the Vernay Survey conducted more than 80 years back, and identify priority sites for bird conservation.  The study covered the hills and forests of Tamil Nadu spanning nine districts.  In total, 262 species of birds were recorded during the survey.  Eight species of birds fall under the threatened category.  Species such as Square-tailed Bulbul Hypsipetes (lecocephalus) ganeesa, Rufous Woodpecker Micropternus brachyurus, Asian Fairy Bluebird Irena puella, and Malabar Whistling Thrush Myophonus horsfieldii still persist in the same old sites reported in the Vernay Survey.  The top five abundant species were the Red-vented Bulbul Pycnonotus cafer, White-browed Bulbul Pycnonotus luteolus, Red-whiskered Bulbul Pycnonotus jocosus, Common Iora Aegithina tiphia, and Purple-rumped Sunbird Leptocoma zeylonica.  The Vaniyar riparian tract in the Shevroys, from its origins in the hills to the Vaniyar dam downstream, is a potential bird conservation site in the Eastern Ghats of Tamil Nadu.

  Birds are important bio-indicators and provide various ecosystem services including pollination, dispersal, and pest control. However, they are threatened by habitat loss, fragmentation, and degradation. Study on species diversity, relative abundance, and habitat associations of avifauna were conducted in Tara Gedam Monastery forest patch and associated habitats from July 2016 to April 2017. Stratified random sampling approach was used to classify habitats and select sampling plots based on vegetation type. Consequently, forest, bushland, farmland, and plantation habitats were used for data collection. Point count and line transect methods were used to collect data, and Shannon-Weiner and Simpson’s diversity indices were used to estimate the avian species diversity. One-way ANOVA was conducted to compare avian relative abundance and richness among the different habitat types. A total of 98 species of birds belonging to 14 orders and 41 families were recorded in Tara Gedam Monastery forest and associated habitats. Eighty-seven resident bird species and eleven Palearctic migrants were identified of which seven species are endemic to Ethiopia and Eritrea. The highest avian diversity (H’=4.23) was recorded in the study area during the wet season.The highest species similarity index (SI=0.47) was recorded between forest and bushland habitats during the wet season, while the lowest similarity index (SI=0.07) was found between bush-land and farmland habitats during the dry season. Species richness and relative abundance of bird species varied between the wet and dry seasons. Besides birds, Tara Gedam Monastery forest supports a large number of other wild fauna species, which indicates the area’s potential to support biodiversity. Therefore, there must be a collaborative work between the monastery and different governmental and non-governmental organizations to protect the entire ecosystem in order to conserve the whole biodiversity of the area in general and the avifauna in particular.
