Studies of ‘optimal foraging’ in birds have concentrated on species which search actively. This paper describes the organization of foraging behaviour under field conditions of a tropical ‘sit‐and‐wait’ predator, based on the choice of trees as vantage points. Preferences shown for different trees did not appear to maximize the birds' rate of capture of prey items, but rates of energy intake were not measured. However, it is possible that selection for ‘optimal’ behaviour in this species is not so strong as in temperate species which search actively.
