A Study on Identification and Population Status of Birds in the Campus of Rani Anna Government College Tirunelveli India

Birds are the important components of the food chain. Birds are vertebrate warm-blooded animals. Birds are ideal bio-indicators and useful models for studying a variety of environmental problems. As increasingly more attention is now being given to ecological studies, the methods employed in field ornithology warrant a closer examination. While in the developed world there has been extensive research on the standardization of bird-count techniques. Population density is the size of a population in relation to a definite unit of space. It is generally expressed as the number of individuals or the populations’ biomass per unit area or volume in Campus of Rani Anna Government College, Tirunelveli India. There are a wide variety of field and statistical techniques for assessing animal abundance, which include complete counts, partial counts, and capture methods. The present study reports for 20 different bird species from 11 orders and 20 families were sighted from the selected sites in the hostel, ground and garden area in the college campus.
