  • Title
    Migratory Pallas’s Gull Larus ichthyaetus (Pallas, 1773): a new record from Sikkim, the eastern Himalaya, India
    Type
    Journal Article
    Description
    The present study documents the first sightings of the migratory Pallas’s Gull at two different locations (Cholamu Lake and Singtam Valley) in the eastern Himalayan state of Sikkim in India. We recommend that long term surveys are required to determine and establish the distribution and status of the species in the state.

  • Title
    Scaling new heights: first record of Boulenger’s Lazy Toad Scutiger boulengeri (Amphibia: Anura: Megophryidae) from high altitude lake in Sikkim Himalaya, India
    Type
    Journal Article
    Description
    Frogs in the genus Scutiger of the family Megophryidae are the highest altitude frogs in the world, and are endemic to eastern Himalaya. Here, we report the occurrence of Scutiger boulengeri (Bedriaga, 1898) in one of the highest altitude lakes in the world, Lake Gurudongmar. This is the first report of Scutiger boulengeri from India and the first record of any amphibian species to be found at an altitude as high as 5270m, thus setting a world record for the highest altitude frog. Scutiger sikimmensis (Blyth, 1855) is another species of the genus Scutiger found in this region. This species is often confused with Scutiger boulengeri due to similar morphology and habitat overlap. We provide a detailed account of both S. boulengeri and S. sikimmensis based on morphology and molecular identification techniques.

  • Title
    Status and distribution of endemic and threatened birds of the Eastern Himalaya in Sikkim, India
    Type
    Journal Article
    Description
    Due to their restricted distribution range and dwindling population endemic and threatened species need considerable attention from ecologists. Sikkim is a part of the Eastern Himalayas Endemic Bird Area that represents high concentrations of globally threatened species. This study collected information on endemic and threatened birds of Sikkim using point count method. The number of species and their density at five elevation zones were calculated. Out of 10 species endemic to Sikkim, five were recorded during the present study. These species were restricted to one to three habitats but densities varied among the habitats. Similarly, out of 17 threatened and 10 near-threatened species of birds that occur in Sikkim, we could observe only three species. The results show that these birds are rare or their occurrence is doubtful in recent years. The principal threat to birds in the state appears to be loss of breeding habitat. Species-specific studies focusing on population status, habitat requirements and assessment of threats are necessary for the execution of conservation measures.

    Sighting of King Cobra Ophiophagus hannah in Sikkim, India: a new altitude record for the northeast
    Type
    Journal Article
    Description
    We report the sighting of Ophiophagus hannah from Yuksam Village bordering Khangchendzonga Biosphere Reserve in Sikkim. The present record signifies a range extention for this species with respect to altitude (1,840m) and habitat (temperate forests) reported for this state and the northeast India.
