Abstract

During the final 3 hr of daylight on 6 February 1989, I recorded the behavior of an American robin, Turdus migratorius, foraging on fruits of the hawthorn, Crataegus monogyna in western Oregon, USA. Fruit intake increased (fewer picked fruits were rejected) as dusk approached and time before flying to roost decreased. Foraging bout length and foraging rate remained constant. The observed behavior may reflect the need for frugivores that are gut-process limited to store fuel (fruits) in an extendible esophagus before nightfall.
