Barn Swallow vs Tree Martin

In short

The Barn Swallow is distinguished by its long, deeply forked tail and glossy steel-blue upperparts, while the Tree Martin has a shorter, less forked tail and duller plumage. Both species are aerial insectivores, but their flight patterns and habitats can help differentiate them.

Identification tips

1. Tail Shape: Look for the long, deeply forked tail of the Barn Swallow compared to the shorter, less forked tail of the Tree Martin. 2. Plumage Gloss: Note the glossy blue upperparts of the Barn Swallow versus the duller plumage of the Tree Martin. 3. Throat Color: Barn Swallows have a rufous-chestnut throat, while Tree Martins have a more uniform grayish-brown throat. 4. Habitat Preference: Consider the habitat; Barn Swallows are more likely in open fields, while Tree Martins are often near wooded areas or urban settings.

Size

Barn Swallows are generally larger with a more pronounced forked tail compared to the smaller, more compact Tree Martin.

Plumage

Barn Swallows have glossy steel-blue upperparts and a rufous-chestnut forehead and throat, with creamy or buffy white underparts. Tree Martins have duller, less glossy plumage with a more uniform grayish-brown appearance and lack the distinct rufous throat.

Behaviour

Both species are highly aerial, but Barn Swallows are known for their acrobatic flight and long-distance migrations, while Tree Martins often display more fluttery flight patterns and are less migratory.

Habitat

Barn Swallows are often found in open areas, including fields and near water, where they can forage for insects. Tree Martins prefer wooded areas, often near water, and are more likely to be found in urban environments.

Voice

Vocalizations are not a primary distinguishing feature; both species have similar chirping calls, but Barn Swallows may have a more varied song.
