abstract

Diurnal time-activity budgets were quantified for Ferruginous Pochard Aythya nyroca wintering in Tanguar Haor, Bangladesh. Individuals spent most time resting (60%), with less time spent feeding (17%), preening (14%) and swimming (9%). The time spent feeding was generally lower than for other Aythya species in winter, perhaps because Ferruginous Pochard feed preferentially at night. Human disturbance during the day may be a significant factor driving this.
