Goose Facts: The Feather on the Thief's Head and the Cry That Warned a Caliph 🪿

If you only know geese as the angry birds of the park pond, this entry will change your mind. The goose facts in al-Damiri's book come wrapped in poetry, a prophet's detective story, and a dawn chorus that turned out to be a funeral announcement.

Goose Facts From the First Line: How to Say “Goose” in 1372

Al-Damiri opens with the word itself. Al-iwazz (الإوز) — hamza with a kasra, waw with a fatha, in case you were wondering how a 14th-century scholar wanted you to pronounce “goose.” One goose is an iwazza (إوزة); a flock is awzun (أوزون). I love that the book treats pronunciation as natural history — before it tells you a single thing the bird does, it makes sure you can say its name.

The Poet Who Heard Pens in Their Honking

Then the microphone goes to Abu Nuwas — the great Abbasid poet of wine and wit, al-Hasan ibn Hani (d. 194 AH). He heard geese honking as pens scratching across parchment: a flock rising off the water, whistling as if from spoons, the squeak of quills on writing sheets. All the poet hears in a takeoff is a roomful of scribes. The book even pauses for his mini-biography before returning to the bird — you came for the goose, you stay for the poet.

The Gosling That Swims at Birth

Then the real goose facts, and they're lovely. Geese love swimming. The chick leaves the egg and swims immediately — no lessons, no practice. While the female sits on the eggs, the male stands guard and never leaves her side for the blink of an eye. The chicks hatch in the last days of the month.

The Feather on the Thief's Head

Now the story this entry should be famous for. A man complained to Solomon, peace be upon him, that his neighbors were stealing his geese. Solomon called out, “Prayer is assembling!” When the people gathered, he preached — and said, almost in passing: “One of you steals his neighbor's geese, then walks into the mosque with a feather on his head.” Somewhere in the crowd, a man reached up and wiped his head. Solomon pointed: “Seize him — he's your man.” The book cites it from al-Dinawari and Ibn al-Jawzi, on the authority of Muhammad ibn Ka'b al-Qurazi. Seven centuries later, “the feather gave him away” is still detection in a single gesture — and GOD had given Solomon a wisdom no lock could keep out.

“Leave Them — They Are Mourners”

The entry's other great scene is darker. Imam Ahmad reports — through Husayn ibn Kathir, from his father, who had met Ali himself — that Ali ibn Abi Talib walked out to the dawn prayer as geese screamed in his face. The people shooed them away. Ali stopped them: “Leave them, for they are mourners.” That same morning, Ibn Muljam struck him down. Ali heard a funeral in the honking of geese — and he was right.

What the Old Doctors Believed About Goose Meat

Every entry ends with khawass — the properties — and the standard warning applies: this is what the old books claimed, not advice. Hippocrates called the goose the moistest of all domestic birds. Its meat is very hot and moist: it fattens the body but fills it with waste, so the book advises borax blown into the throat before slaughter, oil rubbed on the meat before roasting, and plenty of hot spices. Hard to digest, quick to bring on fevers. The fat was believed to help pleurisy and hair loss; the tongue, urinary dripping; a stone from the goose's stomach, drunk in water, looseness of the bowels. The eggs: best half-boiled, good for hot constitutions, bad for colic — take them with thyme and salt, and eat the yolk, not the white.

Frequently Asked Questions

1. How did Solomon catch the goose thief?

   A man told Solomon, peace be upon him, that his neighbors were stealing his geese. Solomon gathered the people for prayer and said mid-sermon that one of them steals his neighbor's geese and walks into the mosque with a feather on his head. A man in the crowd wiped his head — and Solomon had him seized. The entry cites al-Dinawari's al-Mujalasa and Ibn al-Jawzi's al-Adhkiya.

2. Why did Ali call the geese “mourners”?

   On his way to the dawn prayer, geese screamed in Ali ibn Abi Talib's face. When people shooed them, he said, “Leave them, for they are mourners” — and that morning Ibn Muljam assassinated him. The story comes from Imam Ahmad's Manaqib, through Husayn ibn Kathir, from his father, who had personally met Ali.

3. What did medieval doctors believe about goose meat?
