Pacific Swallow vs Barn Swallow

In short

The Pacific Swallow and Barn Swallow can be distinguished by their tail length and breast band. The Barn Swallow has a longer, deeply forked tail with white patches and a prominent steel-blue breast band, while the Pacific Swallow has a shorter tail and lacks a breast band.

Identification tips

1. Look for the tail length: Barn Swallows have longer, deeply forked tails with white patches. 2. Check for the breast band: Barn Swallows have a steel-blue band across the chest, which Pacific Swallows lack. 3. Observe the underparts: Pacific Swallows have darker underparts compared to the creamy or buffy white of Barn Swallows. 4. Consider the geographic location: Pacific Swallows are more likely in southeastern Asia and the southwestern Pacific.

Size

The Barn Swallow is generally larger, with a longer tail, compared to the smaller Pacific Swallow.

Plumage

Barn Swallows have glossy steel-blue upperparts and a rufous-chestnut throat with a broad breast band. In contrast, Pacific Swallows have darker underparts, lack a breast band, and have a shorter tail.

Behaviour

Habitat

Both species are found in open areas, often near water, but the Pacific Swallow is more common in southeastern Asia and the southwestern Pacific, whereas the Barn Swallow has a broader range including North America and Eurasia.

Voice

Vocalizations are not a primary distinguishing feature between these two species, as both have similar swallow-like calls.
