6 Key Differences
Have you ever seen a swallow flying in the air and asked yourself, “Wait, was that a barn swallow or a Pacific swallow?” You’re not alone. I used to mix them up all the time—until I started noticing six little details that made all the difference.
1. Tail Shape and Length
Here’s a quick tip: Barn Swallows have long, forked tails—kind of like scissors in flight. Pacific Swallows? Their tails are shorter and more squared. That’s an easy giveaway.
2. Plumage and Coloring
Barn Swallows shine with a glossy blue back and a rich red throat. Pacific Swallows are more muted, with duller blue feathers and less contrast.
3. Geographic Range
Barn Swallows are world travelers—you’ll see them almost everywhere. Pacific Swallows stick to Southeast Asia and the Pacific islands.
4. Nesting Behavior
I once found a Barn Swallow’s nest under a bridge—very neat and reused often. Pacific Swallows prefer more natural spots and build simpler mud nests.
5. Flight Style
Barn Swallows glide with ease, showing off those long tails. Pacific Swallows flap more and glide less—it’s almost like they’re in a hurry.
6. Social Interaction
Watch for groups. Barn Swallows hang out in flocks, especially near farms. Pacific Swallows are more into quiet couple time.
Size Check:
Barn Swallow: Length 6.7–7.5 in (17–19 cm)
Pacific Swallow: Length 4.7–5.1 in (12–13 cm)
Now you know—next time you see one, you’ll spot the difference like a pro!
