Abstract

The Black-faced Spoonbill (Platalea minor) has often been considered to be a mainly nocturnal feeder. The present study shows that this species is better classified as crepuscular, being predominantly active around sunrise and sunset, but they may also feed during the day and at night. The periods of twilight and the tides interact in the timing of feeding. On average, just over 4 hours per day (17%) is spent for feeding, about 19.5 h (81%) loafing and less than a half hour (1.6%) flying.
