Superb Bird-of-Paradise | It Built Its Own Lighting | Dumb Stupid Birds #44

African Jacana | Carrying Four Children On Two Wings | Dumb Stupid Birds #54

The African Jacana weighs less than a lemon, has toes long enough to walk on lily pads, and carries up to four live chicks tucked under its wings during predator escapes - just eight tiny legs visible from the outside. The female is twice the male's weight, holds territory, mates with multiple males, and delegates all childcare. A complete inversion of bird family structure, operating calmly on a pond in sub-Saharan Africa.

Eurasian Wryneck | The Woodpecker That Quit | Dumb Stupid Birds #52

The Eurasian wryneck is a woodpecker that cannot drill, will not excavate its own nest, and eats almost nothing but ants off the ground. Cornered, it twists its neck nearly half a turn and hisses like a snake. The ancient Greeks spun it on strings in love spells, and its genus name, Jynx, is where English got the word jinx. You have been quoting it for years.

Clark's Nutcracker | The Bird That Plants Forests by Accident | Dumb Stupid Birds #51

The Clark's nutcracker buries between thirty thousand and a hundred thousand pine seeds every autumn, hauling them in a pouch under its tongue and remembering thousands of individual caches under deep snow for up to nine months. The forgotten ones grow. Every whitebark pine forest in the high American West was planted, seed by seed, by a plain gray bird with a brain the size of a peanut that was just trying to stash lunch. You forgot why you walked into the kitchen.

North Island Brown Kiwi | A Bird Pretending To Be A Mammal | Dumb Stupid Birds #50

The kiwi hunts by smell, the only bird with nostrils at the tip of its beak. It has whiskers, heavy marrow-filled bones, fur-like feathers, and two working ovaries. The female lays an egg up to 20 percent of its body weight, so large the bird has to stop eating to finish it. Its closest relative is the extinct elephant bird of Madagascar, meaning its ancestors flew here, looked around, and decided flight was not worth the effort.

Ruff | Three Males, One Frozen Gene | Dumb Stupid Birds #49

The ruff comes in three permanent kinds of male: one fights, one freeloads, and one disguises itself as a female to slip past both. Which one a ruff becomes is fixed before hatching, locked in a chunk of chromosome that flipped backwards around four million years ago. Inherit two copies and the embryo dies. It has balanced fighters, freeloaders and impostors at fixed odds since before our own kind existed.
