Black Swift vs White-throated Swift

In short

The Black Swift and White-throated Swift are both dark, fast-flying birds, but they can be distinguished by their plumage and behavior. The Black Swift is larger and more uniformly dark, while the White-throated Swift has distinctive white markings on its throat and flanks.

Identification tips

1. Look for the white throat and flank patches to identify the White-throated Swift. 2. Note the larger size and all-dark plumage of the Black Swift. 3. Consider habitat: Black Swifts are more likely near waterfalls, while White-throated Swifts are often near cliffs or urban areas. 4. Observe behavior: White-throated Swifts may be seen flying around human structures, unlike the more reclusive Black Swifts.

Size

The Black Swift is larger and bulkier compared to the more slender and smaller White-throated Swift.

Plumage

Black Swifts are uniformly dark with no contrasting markings. In contrast, White-throated Swifts have a striking white throat and white patches on the flanks, which are visible in flight.

Behaviour

Both species are aerial insectivores, but the White-throated Swift is more often seen near cliffs and human-made structures, while the Black Swift is typically found near waterfalls and in mountainous areas.

Habitat

Black Swifts prefer remote, mountainous regions, often nesting behind waterfalls. White-throated Swifts are more adaptable, frequently found in open areas with cliffs and sometimes near urban environments.

Voice

Vocalizations are not a primary distinguishing feature in the field; both species have high-pitched calls, but the White-throated Swift's calls are more often heard due to its affinity for human-made structures.
