eDNA FROM FEATHERS -- A VALUABLE TOOL AND UNIQUE SOURCE FOR IDENTIFICATION OF BIRDS.

eDNA for birds identification is a non-invasive technique that inflicts no damage to the species or habitats under study. It is relatively new data collection approach and opens new ways by which free ranging animals can be studied. The present study aims at the use of non-invasive sampling techniques based on collection of molted or dropped feathers as a tool for identification of birds. For this purpose DNA was isolated and quantified from molted feathers. Since, 12S rRNA has been identified as a reliable molecular tool for genetic species identification, therefore, partial 12S rRNA sequences were amplified from the eDNA of feathers using universal primers. The PCR amplified DNA samples were sent for Sanger sequencing. Phylogenetic trees were constructed on the basis of bioinformatic analysis. This study, therefore, endorses the use of eDNA isolated from feathers as a useful non-invasive tool for identification of birds which can play a pivotal role in avian research and conservation.
