Behaviour

Social behaviour: Communal Mobility: Migratory Elementary unit: FLock

White-throated Needletails are usually observed hunting above forest or woodland. Only in rainy weather, in particularly near approaching storms, they are found hawking for insects above more open country, e.g. in open farmland with scattered trees. This may indicate that their prey, insects, also move from wooded areas into more open space in these weather conditions.

[Eulah Creek, NSW, January 2016]

The way White-throated Needletails often hunt is that part of the flock remains at relatively high altitude, say 100 m, from where they dive down on their prey, which they take at heights of 10-50 m, in rainy conditions also down to near ground level. When not hunting, they have been observed by us circling in thermals.

Food, Diet

Like other swifts, White-throated Needletails are insect hunters. They catch and devour their prey in-flight.

Call(s)/Song

For this species we have recorded the following call(s)/song. The interpretation of their meaning is our own; comments and suggestions for improvement are welcome.

Being the bird species with the fastest wing-flapping flight , White-throated Needletails create enormous thrust with their wings, which makes the wing beats audible. Below an example of a bird passing over at about 15-20 m above ground.
