Abstract
The Spot-billed Pelican (Pelecanus philippensis), a near threatened bird and one of eight pelican species in the world, can be found only in South and Southeast Asia over an area between 129000 and 181000 km2 with strongholds in India, Sri Lanka, southern Cambodia and coastal areas of Sumatra. In India,it is presently distributed in southern and northeastern India with concentrations in Andhra Pradesh, Tamil Nadu, Karnataka and Assam states. The present study deals how the spot- billed pelicans utilize the wetlands as well as their behaviour is noted in order to plan conservation and management strategies for the species.
Highlights
Wetland Wetlands are defined as ‘lands transitional between terrestrial and aquatic eco-systems where the water table is usually at or near the surface or the land is covered by shallow water (1)
The status and colony size of spot-billed pelicans were studied in Tamil Nadu from the month of July 2018 to December 2018
The maximum number of spot-billed pelicans were observed in the month of July; (42), (54) and (73) in Ukkudam-periyakulam, Kurichi kulam and Valankulam respectively whereas the minimum population was observed in the month of December; (6), (0) and (0) in Ukkudam-periyakulam, Kurichi kulam and Valankulam respectively (Fig 1.)
Summary
Wetland Wetlands are defined as ‘lands transitional between terrestrial and aquatic eco-systems where the water table is usually at or near the surface or the land is covered by shallow water (1). Wetlands can be defined as areas of high grsoundwater environments that are characterised by permanent (shallow water bodies) or temporary inundation, or soils having hydric properties. They provide a number of critical ecological functions, including the regulation of water regimes, and support a significant percentage of the world’s biodiversity that have adapted to life in saturated conditions. Majority of the inland wetlands are directly or indirectly dependent on the major rivers like, Ganga, Bhramaputra, Narmada, Godavari, Krishna, Kaveri, Tapti They occur in the hot arid regions of Gujarat and Rajasthan, the deltaic regions of the east and west coasts, highlands of central India, wet humid zones of south peninsular India and the Andaman and Nicobar & Lakshwadeep islands.
