  • Title
    Avian diversity and density estimation of birds of the Indian Institute of Forest Management Campus, Bhopal, India
    Type
    Journal Article
    Description
    A study to find out the bird diversity at the Indian Institute of Forest Management (IIFM), Bhopal, was carried out over a period of nine months from July 2012 to March 2013. IIFM is located on a hill facing Bhadbhada barrage in Bhopal. Physiographically the area is classified as Vindhayan Hills. A total of 106 bird species belonging to 52 families were recorded during the study covering an area of about 93 hectares. The study area was divided into three major habitat types: open scrub, dry deciduous, and urbanized. Bird species were classified into eight feeding guilds: carnivore, ground insectivore, sallying insectivore, canopy and bark insectivore, nectar insectivore, general insectivore, frugivore and water birds. Of the total 106 species observed, 27 species were recorded as winter visitors. Density analysis was done using DISTANCE software and density was found out to be 32.7 birds per hectare. Rank abundance curve was used for assessing species composition in different habitats and during different seasons. In terms of both richness and evenness, open scrub scored the highest rank (72 species, and most even distribution of species). Higher species richness with lower species evenness was recorded during winter season for all the habitats.

    An avifaunal case study of a plateau from Goa, India: an eye opener for conservation of plateau ecosystems
    Type
    Journal Article
    Description
    The lateritic plateaux typical of the midlands between the Western Ghats and the coastal plains of the Arabian Sea are known to be a unique ecosystem with a sizeable endemic flora. However, there is a total lack of studies on the faunal diversity of these plateaux, which are currently experiencing enormous anthropogenic pressures. We conducted a year-long study on the avifauna of the Taleigao Plateau, Goa. The Taleigao Plateau harbours 114 species of birds, accounting for 37% of the avifaunal diversity of the state. The resident bird population did not vary significantly through the seasons. Among the migrant birds, Rosy Starling Sturnus roseus was particularly partial to the plateau. Besides, five species of larks, grassland specialists were also recorded on the plateau. However, the absence of forest birds like the Malabar Pied Hornbill and the Indian Grey Hornbill (recorded earlier) and the predominance of habitat generalists like the House Crow and the Jungle Myna seemed to be the offshoot of heavy anthropogenic pressures on the plateau. It is recommended that at least some plateaux in the belt deserve to be protected from the impact of unsustainable developmental process
