    Abstract

    Our study investigates the physiological changes in the migratory redheaded bunting, Emberiza bruniceps under natural conditions. The study was carried out on captive birds held under natural conditions to see their physiological changes in response to spring and autumn migration. Adult male redheaded buntings were captured from overwintering flocks in India and were acclimatized to captive conditions by keeping them in an outdoor aviary where they experienced natural variation of photoperiod, temperature and humidity. Observations on food intake, body mass and fat score were recorded twice in a year: during late March/early April (departure from India of buntings, spring migration) and late September/early October (arrival of buntings in India, autumn migration). Buntings showed deposition of fats during the spring migration (departure period from India). Deposition of fat was significantly high during spring migration as compared to their arrival period in autumn in India. The change in body mass and food intake was not significant.
