6 Vital Facts I Love
Ever spotted a small bird darting through the sky and thought, “Wait, is that a Barn Swallow or a Chimney Swift?” I’ve been there. At first glance, they seem nearly the same—but they’re not. Let’s break it down with six simple facts I’ve learned from watching them up close.
1. Flight Style Differences
Barn Swallows glide like little sky surfers. Chimney Swifts, though? They flap fast and never seem to stop.
Quick answer: Swallows glide, Swifts flutter nonstop.
2. Tail Shape and Body Appearance
Swallows have that deep forked tail—like a pair of scissors in the sky. Swifts? Their tails are short and squared.
Need to ID one? Look for that forked tail—it’s a swallow!
3. Nesting Behavior
I’ve seen Barn Swallows build mud nests under porches. Chimney Swifts? They stick their nests high inside chimneys.
Where they nest tells you who’s who.
4. Habitat Preferences
Swallows love open fields. Swifts hang around cities and buildings.
Find them near cows? Probably a swallow. In a downtown alley? That’s a swift.
5. Sounds and Calls
Swallows sound cheerful and sweet. Swifts call in high, rapid chips.
Happy twittering? That’s your swallow singing.
6. Migration and Seasonal Sightings
Barn Swallows (Length: 6.7–7.5 in / 17–19 cm) and Chimney Swifts (Length: 4.7–5.1 in / 12–13 cm) both migrate, but their timing and paths differ.
Want to catch them? Watch the skies in spring and late summer.

I still remember the day that sparked my love for birds. I was just a kid, sitting in my backyard, when a tiny bird landed near me. It moved so fast, its feathers flashing in the sunlight, and then it sang—soft, clear, and almost magical. In that moment, birds became more than just creatures in the sky. They became a mystery I wanted to solve.
That curiosity never faded. It led me to study Biology at the University of Scranton, where I dove deep into the science of birds—their behavior, their calls, and the incredible ways they survive. Today, that same passion drives me, and through Earth of Birds, I get to share it with you.
