Diet overview

Insectivore

How it forages

Feeds exclusively on aerial insects (aeroplankton), including flies, beetles, aphids, and spiders, caught in its wide gape while in continuous flight. Often forages in large flocks, especially before storms or during periods of low insect abundance.

When it feeds

Diurnal, active from dawn to dusk. Can remain airborne for extended periods, including overnight, during which it may sleep by entering a state of 'unihemispheric slow-wave sleep' while gliding.
