E26. We borrowed a phrase from human dating and tried to pin it on birds. Turns out they never needed the rulebook. Dr. Wenfei Tong, biologist and author of Bird Love, joins Scott to unpack what bird partnerships actually look like once you stop projecting our scripts onto them, from females who run the territory to males who guard their paternity in deeply weird ways.

In this episode you'll hear about:

• Why the drabbest little brown bird in the garden has one of the wildest sex lives in the animal kingdom
• How a female calls the shots when she holds the better real estate, and what the males do about it
• The cloacal pecking payoff you have to hear to believe

E25. The blue-footed booby has become an internet personality: cartoon feet, a goofy strut, a name that practically begs to be a punchline. But Scott sat down with Dr. Carlos Zavalaga, Universidad Científica del Sur, and one of the people who first taught him how to study seabirds in Peru, and the "fool" reputation falls apart fast. Get a booby in the air or underwater and you're watching one of the most specialized hunters in the bird family tree.

In this episode you'll hear about:

• How six-plus booby species carve up the same ocean without starving each other out
• What 20 years of GPS loggers, depth tags, and bags of fresh fish revealed about who eats what
• Why El Niño, avian flu, and overfishing keep stacking the deck against these birds

E24. Flight is the thing we associate most with birds, so what does it mean when a lineage gives it up? Dr. Scott Edwards, Harvard, joins Scott to unpack how flightlessness evolves, why it keeps happening across the bird family tree, and what the genome reveals about how a bird loses the ability to fly.

In this episode you'll hear about:

• How losing flight reshapes a bird's body, from feathers to forelimbs to that one famously enormous egg
• Why the answer wasn't where geneticists expected to find it
• What an extinct giant and a tiny tropical relative can tell us about where moa actually came from
