Over 130,000 years ago, White-throated Rails migrated across hundreds of miles from Madagascar to the tiny island of Aldabra. Fossil records show that these wayward birds evolved to be entirely flightless, and went extinct when the island was lost to sea level rise. But some 20,000 years…

Every summer, millions of birds flock to the Arctic Circle to find mates and raise their young. In a study published in 2025, paleontologists found evidence of the earliest known Arctic breeding colony from fossils uncovered in northern Alaska. The site dates back nearly 73 million years…

Like today’s swans, the extinct species Annakacygna hajimei and Annakacygna yoshiiensis were quite large. But unlike their modern relatives, these birds lived most of their lives out at sea, and their fossils reveal remarkable adaptations to this unusual lifestyle. This led the researchers…

Thousands of years ago, giant raptors lived on what is now Cuba. Gigantohierax is an extinct genus of eagles whose fossils have been found in local cave deposits and tar seeps. With an estimated weight of nearly 30 pounds, Gigantohierax suarezi, the larger of the two named species, would…

25 years ago, a mysterious cause of eagle and osprey deaths plagued a small town in Arkansas. And in this special episode, we get to the root of it all: small unassuming weeds, also known as invasive aquatic species. In conversation with aquatic plant experts Stacy Holt Jr. and Greg Bugbee…

In the 1990s, eagles in the Southeastern U.S. began dying of a mysterious brain disease. Many years of research identified the culprit: a cyanobacteria that grows on an invasive aquatic plant called Hydrilla — also known as waterthyme. Fish ingested the cyanobacteria, and eagles ate the…

John Edmonstone was born on a timber plantation in British Guiana, and enslaved by Scotsman Charles Edmonstone. He learned taxidermy techniques by accompanying a naturalist on expeditions. In Scotland, he became a free man and began working as a taxidermist. One of his students was a…
