Diners drape a white linen napkin over their heads and eat a whole songbird, bones and all, supposedly hiding the act from the eyes of God. This deep dive explores how the ortolan bunting, Emberiza hortulana, a 16 to 17 centimeter seed-eating bird described by Linnaeus in 1758 and named after the word for gardener, became the most controversial dish in French gastronomy. We explain the biology that made it vulnerable: as a migratory bird it is hardwired to store fat when daylight shortens, so hunters net it in autumn, keep it in darkness to hack its circadian rhythm, and force-feed it millet until it doubles in size.

The episode walks through the drowning in Armagnac, the seven minute roast, the feet-first consumption, and the competing explanations for the napkin ritual attributed to a priest friend of Brillat-Savarin. We cover Cyprus exporting hundreds of casks of pickled ortolans a year, Craig Claiborne’s 4,000 dollar 1975 dinner, Edgar Allan Poe’s story The Duke de l’Omelette, the Three Emperors Dinner of 1867, lobotomy inventor Egas Moniz, Francois Mitterrand’s 1995 last meal, and the scene in Succession. Finally we look at the 30 percent French population decline between 1997 and 2007, the 1999 hunting ban, weak enforcement, and the 2019 study using light geolocators and stable isotopes to prove hunting in southwest France was driving the decline.
