This is Scientific Americans' 60-second science. I'm Erica Barris. Got a minute?

You could be in the Arctic and spot some moss. And then you could be at the tip of South America

and spot the same kind of moss and never find it in between. So how did this particular

plant get so well traveled? Turns out it flew. We've long known that

birds spread seeds, but new research says migrating birds also spread microscopic spores.

The birds harbor tiny parts of plants and lichens in their feathers, setting up similar colonies

thousands of miles apart.

That's according to a study in the journal Pierre J.

Scientists inspected feathers from birds in the Arctic that were about to leave for South America.

Fragments from mosses, algae, lichens, and liverworts were trapped in the feathers,

all of which can grow into new whole organisms.

The researchers think that long-distance flyers such as the American golden plover and the

white rumped sandpiper picked up the spores while lining their nests.

Then when the birds arrive in new places, they molt, leaving behind the feathers and their

precious cargo to start growing again

at the other end of the world.

Thanks for the minute.
