Behaviour |
Social behaviour: Communal | Mobility: Migratory | Elementary unit: FLock |
White-throated Needletails are usually observed hunting in flocks, often of about 50-100 birds, 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.

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.

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.
