Skylark (Alauda arvensis) - threats and concerns.

摘要

This paper discusses the damaging effects of intensive agriculture on the skylark species in the Ousteri Lake region (Tamil Nadu, India). After declaration of the Ousudu Lake as a bird sanctuary, the Government of Puducherry has completely blocked the water for recreation purposes. This has caused the grasslands to be completely submerged under water, as a consequence of which the skylarks have migrated to the surrounding abandoned agricultural fields. When these agricultural fields are ready for second-term cultivation in April to May, this results in the destruction of the skylark nests and its hatchlings during the summer ploughing and irrigation. These activities have reduced the skylark population in the Ousteri Lake area, which needs conservation measures.
