  • 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.

  • Title
    Avifaunal diversity of Manjeera Wildlife Sanctuary, Andhra Pradesh, India
    Type
    Journal Article
    Description
    A total of 164 bird species belonging to 53 families were recorded in the Manjeera Wildlife Sanctuary. Of these 107 species were resident, 55 species were winter migrants and 2 species were summer migrants. The population of the each species in different habitats was estimated. Species richness was observed to be more in agriculture habitat followed by scrubland, grassland and marshy areas, whereas species diversity was observed to be more in scrubland habitat followed by agriculture lands, grasslands and marshy areas. Similarity Index analysis showed that the habitats of agriculture land-scrubland are more similar whereas, habitats of scrubland-marshy area show dissimilarity in the sanctuary.

  • Title
    Birds of Mahi River estuary, Gujarat, India
    Type
    Journal Article
    Description
    The Mahi river estuary is one of the major estuaries of Gujarat. This paper presents a comprehensive list of birds of the Mahi river estuary (nearly 50 km stretch) and the adjacent banks/ravines and defines the avian diversity at three major estuarine gradations with a brief check of similarity and diversity within the three. The present observation is the outcome of a 3 year period from August 2006 to July 2009. A sum total of 118 species belonging to 42 families were reported and listed as on Upstream, Midstream, and Downstream of estuary. No significant difference was seen in the species richness at the three zones; a change in avian composition at upstream and downstream was notable.
