The White-throated Needletail and the Fork-tailed Swift are the only species of swifts recorded in the survey. They are both almost entirely aerial and give spectacular displays of high-speed flying above any habitat, urban or rural. Swifts are most often seen in late summer, nearly always in flocks. They are typically associated with stormy weather when they feed on nuptial swarms of various insects. Both species are annual non-breeding summer migrants to Australia from Northern Asia. Overall, only 24 reports of Fork-tailed Swifts were reported from 19 survey sites and the average flock size was 8 birds.
