Way back in 2019, we first spoke with Trish O'Kane about the Birding to Change the World program she had instituted at the University of Vermont, where she is a lecturer and environmental educator, because of an essay she had written for The New York Times. She's back 5 years later to talk about her new memoir, appropriately titled Birding to Change the World, which recounts her journey from nascent bird obsessive to activist to environmental educator through the effort to protect a much-loved urban park in Madison, Wisconsin.

Also, Emperor Penguin colonies are all accounted for in Antarctica, thanks to poop-tracking satellites.
