Abstract

For 4 consecutive evenings in southern Nicaragua, a group of three Yellow Tyrannulets (Capsiempis flaveola) roosted in the same plant, and always arrived approximately 45 min before last light. Pre-roosting behavior appeared stereotyped and included mutual preening and a peculiar manner of hopping over one another. These three birds presumably left the roost around first light each morning.
