This episode—which is Number 85—is about the Meadowlarks of the world. And it’s not just those three North American species: the Western, Eastern, and Chihuahuan. There are actually 8 bird species we call meadowlarks. The other five are found primarily in South America. We’ll be talking about them today, too. Meadowlarks belong to the New World Bla…

This is Episode 84. Our topic today is the challenge of saving bird species that are very close to extinction. Species like the Spix’s Macaw, which have tiny global populations—whether in the wild, or in captivity. Other familiar examples are the California Condor and the Whooping Crane, whose populations bottomed out at 22 and 23, respectively. Ri…

This is Episode 83. It’s all about birds in the family Odontophoridae. These are the New World quails. Why is this the family of "New World" quails? Because there’s a whole mess of birds we call quails that live in Europe, Asia, Africa, and Australia. But those birds all belong to the pheasant family, Phasianidae. New World quails are shy birds gro…

This is Episode 82. It's all about the ways that scientists track the movements of individual birds.

It’s a symbol of the spring and summer seasons and of the annual rejuvenation of nature. To the casual observer, birds generally come across as caring, attentive parents. Si…

This is Episode 77. It's an overview of seabirds. Some might call them Oceanic birds or Marine Birds. How do we define what is or isn’t a sea bird? Well, it depends on who you ask. There’s no one definition, since “seabird” is an informal term, rather than a scientific one. It doesn’t correspond to a single taxonomic category, or to a single evolut…
