They construct a bulky cup nest in cavities near water. The clutch contains 3-5 white eggs which are incubated for 17 days. The nestlings are fed by both parents for 23-27 days to fledging. They usually raise a second brood.


Their diet consists mostly of flying insects, particularly ants; beetles and bugs and includes large species such as dragonflies and bees.
