    Status and Ecology of the Andaman Crake
    (SACON, 2009) Ezhilarasi, N.; Vijayan, Lalitha
    Andaman Crake is a rare and endemic bird of Andaman Islands. There was no detailed information available on this species and was listed as data deficient till recently. Hence a study was undertaken during 2004-2007 to collect baseline data on the population, ecology and biology of the Andaman Crake. A variety of factors is responsible for Andaman Crake's habitat degradation and loss. In this chapter I briefly highlight key findings of this study, major threats to this species and suggestions for conservation and future research. While these threats and recommendations are given for the conservation of the Andaman Crake, they pertain to several other species ecologically dependent on the wet forests.

    Status and ecology of the Nilgiri Wood Pigeon in the Western Ghats
    (SACON, 2006) Soumasunderam, S.; Vijayan, Lalitha
    Conservation of the species requires a comprehensive picture on the status and distribution, ecological requirements for feeding, breeding and other activities. Ecological studies on most of the endemics have not yet been conducted and hence, such information is not available for any management programmes. Moreover, human impacts on the habitats of most species are also not understood. Hence, the present study was conducted on an endemic, endangered species of the Western Ghats which is considered as Globally Threatened, the Nilgiri Wood Pigeon Columba elphinstonii, addressing mainly its biological and ecological requirements.

    Ecology of Bird Communities in the Anaikatty Hills, Coimbatore”
    (SACON, 2002) Nirmala, T; Vijayan, Lalitha
    Structural and functional aspects of bird communities are believed to have direct relation with the structure of habitat and thereby act as indicators of environmental changes. Various components such as the type of resource, quantity of resource and spatial and temporal distribution of resources play a major role in determining the community structure. In general, the central theme in the functional aspects of the avian community studies has been, how the available resources for biological activities such as foraging, roosting and nesting are partitioned among the existing group of species. Studies on bird community in different habitats are very few in India, and the pattern and processes of a group of species or an individual species were studied separately. The study of birds in relation to habitats will give valuable data for forest management. Area outside protected area network is also equally important for birds and biodiversity conservation. This study was designed to determine the ecology of the bird communities in the mixed dry deciduous forest and scrub forest (SACON) in Anaikatty Reserve Forest, foothills of Nilgiri Biosphere Reserve, Coimbatore, South India.
