Well, it's the end of the year and the whole team is taking a moment to look back at some of our favorite shows from 2023.

My pick has all the elements of a perfect podcast. It's got monsters the size of small airplanes,

a discovery hiding for three decades in plain sight, and the words,

Passerine, Peep Show.

It comes from host to Laura Lickman,

and it's also the start of an epic four-part mini series,

filled with creatures built like tanks and axe murderers. Basically a little

thrill to add to your holiday chill. Enjoy and see you next year. Happy

holidays everybody.

You're listening to Scientific Americans, science quickly, and I'm Flora Lichtman.

This week I want to take you bird watching,

but I'm not talking about an ordinary Passerine Peep Show.

We are skipping the songbirds.

It's a no-fly zone for hawks and raptors.

Waterfowl?

Throw in the towel.

The birds were gonna meet. They're not like anything you've ever peeped.

They used the big as an axe to kill prey.

So just imagine the largest thing you've ever seen alive flying.
