Population densities and diurnal activity pattern of the Indian Roller were studied in Nagapattinam District over three years in different habitats. The agricultural lands supported the highest populations (41km-2), followed by river banks (36km-2) and social forests (32km-2); populations showed yearly variations in numbers and density in all habitats. On average, birds were observed to spend most of the day scanning (57%), with the remainder divided among feeding (16%), flying, (12%), preening (10%) and resting (5%).
