Birds do one thing to stay warm

When the temperature drops it's a race to pull out your jackets and scarves. After all, who wants to walk around being cold?

While we're busy sticking our heads into those scarves and anything else we can find to keep warm, birds are doing pretty much the exact same thing.

A new study has confirmed the popular belief that birds keep their beaks warm by tucking them into their feathers.

It's hard to believe the cutest bird act of all is really just a ploy to fight off the cold but there you have it.

Researchers tested this theory in the wild for the first time, observing 9 species of shorebirds.

They found that birds with bigger beaks tucked more and for longer periods of time than birds with smaller beaks.

Scientists explained that the bigger the bill the more heat was being released which is great if you're a bird in California, but not so much if you're a bird in the North.

Perhaps there should be a market for tiny scarves for our feathered friends.
