Swallows & Swifts

Built for speed, shaped for flight, and easier to identify once you watch how they fly.

How to Notice Swifts & Swallows

Where to Find Them

Look over ponds, rivers, farms, neighborhoods, bridges, cliffs, and open fields. Swallows feed almost anywhere insects fill the air, while swifts favor cliffs, canyons, waterfalls, and tall buildings.

What to Watch For

Ignore color at first. Flight shape is usually the fastest clue. Watch tail length, wing shape, and overall silhouette before worrying about plumage.

Listen Closely

Swallows chatter constantly around nesting colonies, while White-throated Swifts fill canyons with sharp calls as they race overhead.

Masters of the Air

Few bird families are harder to photograph. Swallows and swifts rarely stop flying, constantly changing direction as they chase insects through the air.

The challenge is part of what makes this family so rewarding. From sunrise to sunset they patrol the air, chasing insects with incredible speed and precision. Instead of waiting for prey to come to them, they turn the entire sky into a hunting ground.

Barn Swallow One of Utah's most familiar summer birds. The long forked tail and rich rusty throat make it one of the easiest swallows to recognize when it slows down long enough to perch.

Shape Beats Color

Most swallows are silhouetted against a bright blue sky, making colors surprisingly difficult to see. Learning their shapes is often the quickest path to identification.


Every Species Builds a Different Home

Nests are one of the easiest ways to remember Utah's swallows.

  • Barn Swallow — Mud cups beneath porches and barns.
  • Cliff Swallow — Mud colonies under bridges and cliffs.
  • Tree Swallow — Tree cavities and nest boxes.
  • Bank Swallow — Burrows dug into sandy riverbanks.
  • White-throated Swift — Cliff cracks and narrow rock crevices.

Once you learn the nests, you start noticing the birds differently. A bridge lined with mud apartments almost always means Cliff Swallows, while a single mud cup beneath a porch points to a Barn Swallow. Nest location often identifies the bird before you ever get a close look.

Life on the Wing

Swifts push aerial life to the extreme. Their tiny feet are built for clinging to vertical surfaces rather than perching, and they spend nearly their entire lives on the wing.

The first time I truly appreciated White-throated Swifts was while exploring Havasupai. They never seemed to slow down, racing through the canyon and disappearing around cliffs before reappearing moments later. Watching them there made me realize these aren't simply birds that fly well—they're built for a life almost entirely in the air.

White-throated Swift Fast, agile, and perfectly adapted to life in the air.
