Abstract : Change of environment is a very serious problem for the survival of living organisms specially birds that affects many physiological activities of their body. There are many biotic and abiotic factors which are responsible for decline of the bird’s habitat in the environment. The temperature, rainfall and availability of the food are the main important factors which affects biodiversity of avian species in the nature. Climate change is the result of many human activities like deforestation, excessive use of energy and over use of fossil fuels. There are some other natural disturbances like volcanic eruptions, solar variability, etc. which directly affects the ozone layer present in the atmosphere. It is another source of climatic change in the nature and is totally responsible for the decline of avian fauna in the natural surroundings. Present study focuses on harmful effects of climatic changes on the biodiversity of some avian species of Kanpur. The data of some native, domestic and wild species of birds were collected in the month of July and August, November and December and April and May 2011. It is clearly evident from the above study that the variety of birds is declining and is becoming extinct day by day due to climate changes in the environment by many anthropogenic activities.
